Book excerpt: Aim: To compare early implant failure, template-related complications, and virtual planning accuracy of computer-assisted template-based implant placement using conventional impression and scan model or digital impression using conventional impression and scan model or digital impression to rehabilitate partial edentulous patients using flapless or mini-flap procedures and immediate loading.u2028Materials and methods: Any partially edentulous patients requiring at least 1 implant to be plan on three-dimensional (3D) cone beam computed tomography (CBCT) scans using a dedicated software were enrolled in the trial. Patients were randomised according to a parallel group design into two arms: intraoral digital impression (fully digital group) versus conventional impression and scan model (control group). Implants were to be placed flapless and loaded immediately, if inserted with a torque over 35 Ncm, with reinforced provisional prostheses. Three deviation parameters (horizontal, vertical, and angular) were defined and calculated between the planned and placed implant positions and analyzed statistically. Results were compared using a mixed-model repeated-measures analysis of variance (u03b1=0.05).Results: Twelve patients were randomised to the fully digital group (6 patients with 17 implants) and control group (6 patients with 20 implants). The mean error in angle was 2.56u00b11.52u00b0 (range 0.3u20135.0u00b0) in the fully digital group and 2.18u00b11.41u00b0 (range 0.3u20135.8u00b0) in the control group (P=0.519); in the horizontal plan (mesio-distal), the mean error was 0.57u00b10.32 mm (range 0.1u20131.1 mm) in the fully digital group and 0.43u00b10.26 mm (range 0.1u20130.9 mm) in the control group (P=0.249); in the vertical plan (apico-coronal), the mean error was 0.67u00b10.51 mm (range 0.0u20131.6 mm) in the fully digital group and 0.43u00b10.32 mm (range 0.0u20131.2 mm) in the control group (P=0.180).Conclusions: With the limitation of the present randomized controlled trial, intraoral digital impression may be a viable option to conventional impression and scan model for the rehabilitation of partial edentulous patients by using computer-guided template-assisted implant placement.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To compare accuracy and complications of computer-assisted template-based implant placement using conventional impression and scan of a physical stone model or intra-oral scanning to rehabilitate partial edentulous patients.u2028Materials and methods: Any partially edentulous patients with at least five residual teeth, requiring at least one implant to be planned on three-dimensional (3D) cone beam computed tomography (CBCT) scan according to a computer-assisted template-based protocol were enrolled. Patients were randomised according to a parallel group design into two arms: intraoral digital impression (fully digital group) or conventional impression and scan model (conventional group). Implants were placed flapless or with a minimally invasive flap and conventionally loaded after 5 months. Outcome measures were: implant and prosthetic success, complications, accuracy, and peri-implant marginal bone loss. Three deviation parameters (angular, horizontal, vertical) were defined to evaluate the discrepancy between the planned and placed implant positions. Results were compared using a mixed-model repeated-measures analysis of variance (u03b1=0.05).Results: Twenty patients (11 females and 9 males; mean age 45.4 years old) were randomised to the fully digital group (10 patients with 28 implants) or conventional group (10 patients with 29 implants). No patients dropped out. No implant or prosthesis failed up to 1 year after loading. One implants in the fully digital group was placed free-hand due to limited inter-arch space. No other complications were experienced during follow-up. Difference between groups were not statistically significant (p = 0.999). The mean error in angle was 2.32u00b11.44u00b0 (range 0.3u20135.0u00b0; 95% CI 1.17 to 2.23u00b0) in the fully digital group and 2.10u00b11.18u00b0 (range 0.3u20135.8u00b0; 95% CI 1.52 to 2.38u00b0) in the conventional group (P=0.550); in the horizontal plan (mesio-distal), the mean error was 0.52u00b10.30 mm (range 0.1u20131.10 mm; 95% CI 0.39 to 0.61 mm) in the fully digital group and 0.44u00b10.26 mm (range 0.1u20130.9 mm; 95% CI 0.30 to 0.50 mm) in the conventional group (P=0.279); in the vertical plan (apico-coronal), the mean error was 0.58u00b10.44 mm (range 0.0u20131.6 mm; 95% CI 0.44 to 0.76u00b0) in the fully digital group and 0.46u00b10.34 mm (range 0.0u20131.2 mm; 95% CI 0.28 to 0.52u00b0) in the conventional group (P=0.250). One year after loading, the mean marginal bone loss was 0.14u00b10.12 mm (range -0.1u20130.4 mm; 95% CI 0.11 to 0.19 mm) in the fully digital group and 0.18u00b10.13 mm (range -0.1u20130.6 mm; 95% CI 0.15 to 0.25 mm). The difference was not statistically significant (P = 0.2942).Conclusions: With the limitations of the present trial, intraoral digital impressions showed similar results compared to conventional impression and scan model. Digital impression may be a viable option for the rehabilitation of partial edentulous patients when computer-guided template-assisted implant placement is used.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Static computer-aided implant surgery is a predictable and widely accepted procedure, its accuracy being within the clinical acceptable range in the majority of clinical situations. Usually the 3D model of the bone and surrounding structures is obtained via cone beam computed tomography (CBCT) and the patientu2019s oral condition can be acquired conventionally and then digitalized using a desktop scanner - partially digital workflow (DW) or digitally with the aid of an intraoral scanner - full DW.The aim of the present pilot study is to compare the accuracy of a full digital workflow to partially digital workflow for a limited edentulous space (1 to 3 dental units) using an inspection tool software. Null hypothesis tested: full digital WF is more accurate comparing to partially DW.Materials and methods: The study was conducted in accordance with ethical principles including the World Medical Association Declaration of Helsinki, approved by the University Bioethical Committee, registered (ClinicalTrials.gov Identifier: NCT03814655) and written consent of each subject was obtained.Patients with Kennedy Class III partially edentulism, good general health, acceptance of dental implant treatment, acceptance of pre-operative CBCT, not requiring bone graft, not limited mouth opening were included.The full DW included: intraoral scan of the partially edentulous site, antagonists and occlusion registration, CBCT with radiopaque customized tray placed over the partially edentulous arch; merging files in R2 Gate planning software (Megagen, Korea), implant placement and digital scanning of implants position (.stl u2013 Stereolithography file).In the partially DW, digital impression was replaced with a conventional impression and poured casts are scanned with a desktop scanner.Results: 20 patients were enrolled in this prospective, pilot study and 38 implants were inserted using tooth-supported surgical templates and a flapless technique. Neither complications nor unexpected events occurred during implants insertion.22 implants were inserted using full DW. Inserted and planned implant position were compared using Geomagic Qualify 2013 software (3D Systems,USA).The mean 3D errors of implant positioning for the two insertion protocols were: 0.62mm (u00b10.42) entry point, 0.98mm (u00b10.73) at the implant apex, 2.1 (u00b10.35) angular deviation for full DW, respectively 0.68(u00b10.57), 1.02mm (u00b10.43) and 2.4 (u00b10.22) for partially DW. The t test for implant position showed no statistically significant differences (p > .05) in accuracy between full DW and partially DW, rejecting the null hypothesis tested.Conclusions and clinical implications: Within the limits of the present pilot study, the surgical template used has proved high accuracy for implant insertion, both in full and partially DW.The results of this study suggest that a full digital workflow for computer-guided implant surgery in partially edentulous patients is a reliable method and could be used in clinical situations.

Available in PDF, EPUB and Kindle. Book excerpt: BackgroundRecently, surgical templates without metallic sleeves have been designed and introduced in the dental market, with the goal to make guided surgery work-flow faster and easier. Nevertheless, there is still lack of data about their accuracy and predictability.Aim/HypothesisTo compare virtual planning accuracy of novel computer-assisted, template-based implant placement techniques, which make use of CAD/CAM stereolithographic surgical templates with or without metallic sleeves. Furthermore, to compare open versus closed sleeves for templates without metallic sleeves.Materials and MethodsAny partially edentulous patients with at least five teeth in two different quadrant, requiring at least one implant to be placed according to a computer-assisted template-based protocol were enrolled. Patients were randomized according to a parallel group design into two arms: surgical template designed and fabricated with (test group) or without (control group) metallic sleeves. Implants were placed according to the manufacturer's instruction. Immediately after implant placement, three deviation parameters (angular, horizontal, vertical) were defined to evaluate the discrepancy between the planned and placed implant positions. Furthermore, implant and prosthesis survival and success rates were evaluated one-year after loading.ResultsForty-one implants were placed using surgical templates with metallic sleeves while 49 implants were placed with a surgical template without metallic sleeves. Of these, 16 implants were placed through open sleeves and 33 through closed sleeves. There was a statistically significant difference in angle (p = 0.0212) and in the vertical plan (p = 0.0073) with lower values for implants placed with a surgical template without metallic sleeves. In the test group, close sleeves were more accurate compared with open sleeves in angle (p = 0.0268) and in horizontal plan (p = 0.0477). One-year after implant placement, no implant and no prosthesis failed. No major complications were experienced. Two minor prosthetic complications were experienced in the control group versus none in the test group. The difference was not statistically significant (0.2047).Conclusions and Clinical ImplicationsWith the limitations of the present study, surgical templates designed without metallic sleeves were more accurate in the vertical plan and angle compared to the conventional template with metallic sleeves. Open sleeves should be used in the molar region only in case of reduced space. Further researches with longer follow-up are needed to confirm these results.

Available in PDF, EPUB and Kindle. Book excerpt: Physical attractiveness of the face has a significant impact on the social life and daily interaction of individuals as well as one’s general perception of life. Proper surgical planning for aesthetic facial surgery requires a meticulous analysis of the patient’s current and desired facial features from the perspective of both soft and hard tissues. Significantly greater changes to facial aesthetics can be made via the alteration of the main bony structures of the face than by alteration of soft tissue and skin alone. Various surgical and clinical techniques are available for the augmentation, reduction or refinement of the most prominent aspects of facial aesthetics, such as alterations to the cheek, chin, nose, para-nasal area, as well as the angle of the jaw. These techniques can be categorized as office-based or non-invasive techniques (filler injections, facial liposculpture or liposuction to modify the soft tissue of the face) and invasive surgical interventions such as facial prosthesis and maxillofacial osteotomies. In order to achieve the optimum aesthetic results for patients who undergo bi-maxillary or mono-maxillary orthognathic surgery, it is of paramount importance to utilize a hard and soft-tissue integrated approach. These integrated approaches have utilized the latest techniques in 3-dimentional printing, computer-assisted surgery, tissue engineering and stem-cell therapy in order to achieve positive and lasting outcomes. Integrated Procedures in Facial Cosmetic Surgery includes chapters that focus on facial analysis and clinical evaluation and best practices in surgical techniques such as: principles of bone contouring; genioplasty; mentoplasty; malarplasty; rhinoplasty; orthognatic surgery and intra-oral plastic surgery; lifting procedures like blepharoplasty; surgical approaches to cleft lip and palate surgery; as well as the principles of facial photography. Written by a team of renowned international experts, this textbook features over 900 original photographs, fully illustrating each procedure in a stepwise manner. Integrated Procedures in Facial Cosmetic Surgery is an essential companion for oral and maxillofacial surgeons, plastic surgeons and otolaryngologists, as well as for cosmetic surgeons and clinical residents dealing with face rejuvenation. Its contents will also be of interest to dentists, prosthodontists, periodontists, radiologists, general surgeons, and dermatologists.

Book Synopsis Accuracy of Digital and Conventional Implant Impressions by : Bohner Lauren
Download or read book Accuracy of Digital and Conventional Implant Impressions written by Bohner Lauren and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to ensure a correct occlusion and fit of restorations, the accuracy of entire arch is required. In these cases, the quality of the dental cast relies on the digitizing and machining processes provided by CAD-CAM systems. As geometric errors may be introduced during the step of scanning and manufacturing of casts, their accuracy is still questionable.The purpose of this study was to compare the accuracy of casts obtained using digital and conventional implant impressions. A maxillary model containing dentalimplants on the region of canine and pre-molar was used as master model. Dental casts (n=10) were fabricated through both conventional and digital implant impressions. The conventional casts (CC), stereolithographic casts (SC) and the master model (MM) were digitized and the accuracy was determined through a deviation analysis and linear measurements. Data were analyzed using Student t-test and ANOVA with p=0.05. SC showed higher deviation at vestibular (CC: 41 u00b1 28; SC: 117 u00b1 37 u03bcm) and lingual cusps (CC: 40 u00b1 19; SC: 80 u00b1 42 u03bcm) in comparison to CC. No statistically significant difference was found for linear measurements of conventional and digital casts. The entire-arch accuracy was comparable between casts. However, in located points, stereolithographic casts were less accurate in comparison with conventional casts.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: BackgroundThree-dimensional preoperative implant planning may help to achieve a more predictable postoperative implant position, minimizing anatomical risks and unfavorable prosthodontic outcomes. While different studies investigated the accuracy of computer-assisted implant placement with static CAD/CAM fabricated surgical templates, information on completely free hand and partially guided approaches is limited.Aim/HypothesisTo compare the postoperative implant position with the virtually planned using free hand, pilot drill and fully guided surgical approaches. The hypothesis was that there would be no differences in the accuracy between the 3 surgical protocols.Material and MethodsA controlled in-vitro study with 60 identical maxillary models (3D printed, polilactid) missing the teeth 16, 15, 24, 25, 26 and 27 was performed. The model and tooth setup were digitized with a cone beam computerized tomography (CBCT) and laboratory surface scan, and superimposed using SmartFusion technology. The study coordinator planned the ideal positions for the implants 15, 24 (13/4.3mm) and 26 (8/4.3mm) with the NobelClinician software. Twenty surgeons viewed this ideal planning and placed totally 180 implants using 3 protocols: A) free hand: mentally guided 2/3.5/4.3mm osteotomies (OST) and implant placement (IP), B) pilot drill: template-guided 2mm OST (tooth supported NobelGuide template, 2mm sleeve) combined with free-hand 3.5/4.3mm OST and IP, C) fully guided: template guided OST and IP (tooth supported NobelGuide template, 2/3.5mm inserts with 4.3mm sleeve). Three-dimensional differences between the digitized postoperative and planned implant positions were measured.ResultsFor the implant protocols A (free hand) vs B (pilot drill) vs C (fully guided) the mean absolute differences (u00b1 SD; range) between the postoperative and the virtually planned implant positions were 1.1mm (u00b10.8; 0.2-4.7) vs 0.7mm (u00b10.4; 0.1-1.8) vs 0.5mm (u00b10.3; 0-1.6) at the entry point, 1.5mm (u00b10.7; 0.3-3.2) vs 1.2mm (u00b10.6; 0.4-2.5) vs 0.7mm (u00b10.4; 0.1-2.1) at the tip, and 5.1u00b0 (u00b14.5; 0.1-27.3) vs 5.0u00b0 (u00b13.2; 0.7-19.0) vs 1.9u00b0 (u00b11.6; 0.1-8.6) for the angle.

Book excerpt: Introduction: Studies demonstrated that the accuracy of intra-oral scanners can be compared with conventional impressions for most indications. However, little is known about their applicability to take impressions of multiple implants.Objective: compare the accuracy between digital impressions and different conventional printing techniques in implants in order to observe differences of the novel digital impression with the conventional techniques.Material and Methods: A stone cast of an edentulous mandible with 4 implants was fabricated to serve as master cast (control), two master models were made: one with parallel implants (Model 1)and another with uneven implants(Model 2). Model 1: 4 types of impressions were taken(Group A: tray impressions with reposition abutments; Group B: Open tray impression groups for dragging copings, without splinting; Group C: Open tray impressions for ferrules; Group D: Using 3M u2122 True Definition Scanner system).Model 2: 3 types of impressions were taken(Group E: tray impressions with reposition abutments; Group F: Open tray impression groups for dragging copings, without splinting; Group G: Using 3M u2122 True Definition Scanner system).Master casts and conventional impression casts were digitized with na extraoral high-resolution scanner. Standard tessellation language (STL)data sets from the seven groups of digital and conventional impressions were superimposed with the STL data set from the master cast to assess the 3D (global)deviations. To compare the master cast with digital and conventional impressions.Results: Statistical analysis was performed using the IBMu00ae SPSSu00ae Statistics Vs. 24, NY, USA.The normality of the distributions was analysed with an Kolmogorov-Smirnov test. The median comparison was performed using The differences between the median were analyzed using non-parametric Krustal-Wallis and Mann-Whitney tests with a significance level of p

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Dental implantation is a standard procedure for replacing missing teeth. The utilization of a cone beam computed tomography (CBCT)-assisted surgical template allows predictable flapless results, with implant placement plans performed with accuracy before the actual surgery.Aim: The study was conducted to evaluate the accuracy degree of computer-guided 3D planning program 3Shape for implant insertion in partially edentulous patients. Methods: Computer-guided implant surgery was performed in 23 patients with 57 implants in total. Preoperative CBCT scans were fused with patientu2019s casts to produce the surgical templates. Postsurgery CBCTs were also performed after the implant placement. The collected data were used to analyze the possible differences of the implant fixture body placement between preoperative plan and postoperative actually placed implant, evaluating the angulation and distance errors.Results: The mean angulation errors between the preoperative planned and postoperative placed implant was 5.84u00b0 u00b1 1.87u00b0; the mean distance errors between the planned and actually placed implants were 0.67 u00b1 0.38 mm horizontally and 0.74 u00b1 0.48 mm vertically at the implant neck and 0.82 u00b1 0.51 mm horizontally and 0.74 u00b1 0.39 mm vertically at the implant apex for all 57 implants.Conclusions: Computer-guided implant planning and insertion with 3Shape software, seems to provide sufficient accuracy, although more clinical studies should be conducted. Deviations are mainly related to CBCT accuracy and the implementation of the digital radiographic data to the 3D model through the software planning system.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives:Computer-guided surgery has been validated since the introduction of digital technology in the early 2000s as an efficient and reliable procedure for obtaining functional and aesthetic outcomes. The purpose of this article is to describe a fully digital workflow that was used to perform computer-guided flapless implant placement in an edentulous patient without the use of conventional impressions, model casting and a radiographic guide. Material and Methods:The digital data for the workflow was acquired using an intraoral scanner and cone-beam computed tomography (CBCT). The image fusion of the intraoral scan data and the CBCT data was performed by matching the resin markers placed in the patientu2019s mouth. The definitive digital data were then used to design a prosthetically driven implant position, a surgical template and a computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated fixed dental prosthesis. Immediate restoration was performed using surgical templates and fixed dental prosthesis immediately after implant placement. After implant placement, accuracy of implant placement was evaluated using a 3D image processing software. Results: The average angular deviation between the planned and placed implant positions was 1.1u00b0 with a minimum deviation of 0u00b0 and maximum deviation of 3.2u00b0.Conclusions:The results of this study suggest that a full digital workflow for computer-guided implant surgery in edentulous patients is a reliable method.

Available in PDF, EPUB and Kindle. Book excerpt: Fully digital implant-prosthetic reconstruction in dental officeBackgroundPrecise documentation of the oral cavity and proportions in the face area is crucial not only in dentistry, e.g. prosthetics, orthodontics or orthognathic surgery planning, but also in implantology. Current imaging methods together with dental impressions enable a satisfactory imaging of tissues, which is required for a given purpose. Mainly dental impressions and plaster casts are used for reproduction of the situation in the oral cavity. Usage of an intraoral scanner is one of the new possibilities how to document and preserve 3D data about patients. Intraoral scanning is a non-invasive method, well tolerated by patients and more time effective compared to traditional dental impressions with dental impression trays and appropriate impression material. A record from the intraoral scanner consists of single pictures and video-sequences. Aim/HypothesisThe aim of study was to evaluate the precision of fully digital implant-prosthetic reconstruction ASTRA TECH Implant Systemu2122 EV in dental office using Triosu00ae 3Shape Dental Systems digital intraoral scanner, 3D print and CAD /CAM techniques to create prosthetics components. Materials and MethodsProspective study of 20 implants AstraTech EV was prepared. The range of patients at implants surgery moves from 16 to 35 years. Multidisciplinary therapy by the surgeon, orthodontist, and prosthodontist before implant insertion was monitored. 3Shape TRIOSu00ae 3 - a three in one digital impression solution and 3D printed model were used before computer-aided design and computer-aided manufacturing. The CAD /CAM techniques - abutments (Dentsply Int.), Zircon Zahn (Prettauu00ae Zirconia) were used to establish a framework. The aesthetic appearance was checked mainly from the point of view vertical position of framework and loss of bone marginal support. For every patient we checked step upper and lower jaw digital impression, occlusion, create prosthetics components including digital models in articulator, CAD/CAM reconstruction. Rescanning of 3D print model and X-ray image after reconstruction helped to evaluate the results. ResultsCase reports demonstrate the functional and esthetic results. A good or acceptable aesthetic appearance at the last observation was found in 98 % subjects. 3D reconstruction of occlusion helped us to prepare optimal occlusion without problems with registration material. Also vertical position of the implant-supported crown was precise registered, especially in subjects with no incisor contact. Rescanning process and X-ray image after reconstruction confirmed the acceptance of digital impression and 3D print model in clinical praxis. Conclusions and Clinical implicationsThe aesthetic and functional result has been achieved. Very important was that during patient rehabilitation no need to change occlusal field adjustment. No biological and mechanical complications were found.

Available in PDF, EPUB and Kindle. Book excerpt: Implant dentistry has become a standard option for the rehabilitation of fully and partially edentulous patients. With the ever-increasing number of dentists involved in implant dentistry, it is essential to ensure that their treatment methods follow the highest standard. The ITI Treatment Guide series, a compendium of evidence-based implant-therapy techniques in daily practice, is written by renowned clinicians and provides a comprehensive overview of various therapeutic options. Using an illustrated step-by-step approach, the ITI Treatment Guide shows practitioners how to manage different clinical situations, with the emphasis on sound diagnostics, evidence-based treatment concepts, and predictable treatment outcomes. The second volume of the ITI Treatment Guide is devoted to the restoration of partially dentate patients. Central to this volume of the ITI Treatment Guide are loading protocols available to the clinician and the patient and how they relate to various treatment indications, including both single and multiple missing teeth in the posterior and anterior regions of the mouth. Among potential topics for upcoming volumes are implant placement in extraction sockets, loading protocols in edentulous patients, implant therapy in the esthetic zone in extended edentulous spaces, and many more.
