Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To identify and compare possible risk indicators associated with failure of multiple versus single dental implants Materials and Methods: A retrospective analysis was performed on patients with more than one implant who had experienced biological failure of one or more implants at the Faculty of Dentistry, University of Toronto (January 1979 to June 2018). Data was used to identify possible factors associated with multiple dental implant failures and compare these factors between individuals with single and multiple implant failures. Associations between various factors and multiple implant failure were reported. Results: Excluding history of implant failure, the following factors were found to be associated with MIF: machined surfaces, post-operative infections, presence of certain prostheses opposing the implant, periodontitis, alcohol consumption, history of chemotherapy, and use of antidepressants. Conclusions: Provision of implant-based care for patients presenting with factors associated with multiple implant failure should be undertaken with caution.

Available in PDF, EPUB and Kindle. Book excerpt: Objectives: Dental implants have predictable outcomes and high survival rates. However, a small subset of patients experience implant failure. A retrospective review of charts at UBC was conducted to determine how patient-, disease-, site-, surgeon- and implant design-centered risk factors affect the survival of implants. Methods: A review of implants placed between 1989-2006 was completed. Inclusion criteria required a one-year post-placement diagnostic radiograph. Implant failure was defined as the loss or removal of an implant at any time. Bivariate analyses were used to identify variables associated with implant failure. Risk factors with p-values

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: With advanced technology, short implants are more commonly used and have proven to have a relatively reliable curable efficacy. A consensus has not been reached regarding potential risk factors related to the loss of short implants.Purpose: This large-sample retrospective study concentrated not only on patient characteristics and medical procedures but also on the features of implants in order to uncover the risk factors associated with short implants.Methods: Between 2014 and 2017, a total of 7001 implants were inserted at Nanjing Stomatological Hospital, Medical School of Nanjing University. Among the all, 1236 short implants were included after being evaluated according to the inclusion and exclusion criteria. In organizing the detailed information, seven variables including bone grafting procedure, age, gender, diameter of the implant, implant position, surface treatment and definitive restorations were taken into consideration. The chi-square test, Kaplan-Meier test, logistic regression and multifactorial Cox regression analysis were employed to explore the risk factors.Results: The cumulative survival rate (CSR) of short implants was 96.36%, slightly lower than that of the standard implants (98.16%, P

Book excerpt: Treatment planning for implant therapy has changed dramatically in recent years as new protocols have evolved for techniques such as immediate loading and the use of short implants. This new edition has been updated to reflect the most important advances in implant dentistry, while still focusing on the patient risk assessment that is essential to successful long-term implant treatment. This book offers a clear, practical methodology for defining and evaluating the impact of various risk factors on individual patients considering therapy. In addition, specific guidelines and checklists are included to give specialists and general practitioners alike increased confidence in discussing implant therapy with their patients. The risk factors and limitations associated with various presentations of edentulism are described in detail, and the safest treatment options are given for each, including surgical protocols and solutions to bone-related problems.

This book was released on 2016-01-27 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of implants, is to restore the patients stomatognathic system to normal contour, function, esthetics and thereby improvinng speech and health. Despite its high success rates, failures like biological, technical, and esthetic complications do occur in a percentage of cases. Implant failure is a multifactorial process, which can occur right from the selection of the patient, treatment planning, surgical stages, prostheses designing, fabrication and maintenance of implant. A better understanding of the factors associated with implant failure, will provide data for planning future studies, facilitate clinical decision making and ensure implant success. Hence, it becomes mandatory for the clinicians to know 'why' the implants fail and how best they can overcome and avoid the problems associated with it. To make the understanding easier the failures are discussed under the following headings: (a) Criteria for success of osseointegrated endosseous implants, (b) Parameters used for evaluating implant failures, (c) Classification of implant failures, (d) Management of implant failures and (d) Maintenance

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Implant stability has been recognized as an essential factor link to osseointegration and predicts the survival rate of dental implants. The resonance frequency analysis (RFA) is a noninvasive device providing results in the form of the implant stability quotient (ISQ). The primary stability is also influenced by numerous factors such as surgical technique, implant morphology as well as bone quality and quantity. In the posterior maxilla, the sparse bone density leads to low primary stability. Aim: This retrospective study aims to analyze the factors that influenced the primary stability of dental implant of posterior maxilla.Material and methods: Patients records of treatment performed between January 2014 to December 2018 were reviewed for primary implant stability. Patients who had Straumannu00ae implants at posterior maxilla and exhibited RFA both buccal and mesial area immediate implant placement were included. The following variables were determined; patient age, gender, implantation region, timing of implant placement after tooth extraction (immediate placement, u2264 4 months after extraction, > 4 months after extraction), implant geometry (diameter and length), and adjunctive procedures during implantation (guided bone regeneration and transcrestal osteotomy). The RFA value was used The Kolmogorov-Smirnov Test to determine normal distribution. The Chi-Square Test was applied to compare the relationship between qualitative variables and the Kruskalu2013Wallis test was used to compare the mean. The Pearson correlation coefficient was used to determine correlation.Results: Seventy implants in 53 patients (male 19, female 34) were found. The mean age of this sample size is 59.04uf0b11.41 years old. The mean value of RFA of the buccal area is 65.76uf0b11.44 and the mean of RFA of mesial area 66.59uf0b11.55. The RFA value of the buccal and mesial area was significant correlate (p

Available in PDF, EPUB and Kindle. Book excerpt: Significant progress in the field of implant dentistry has led to various trend shifts with regard to treatment indications, implant parameters as well as surgical procedures. Compared to edentulous jaws in the past, the single-tooth gap represents the primary indication for implant placement today. Advances in oral regeneration have enabled implant therapy for more and more patients, and new implant designs as well as novel surgical techniques have broadened the spectrum of implant therapy.Recognizing changes in the field implant dentistry is crucial for the development of the field. Thus, we aimed to perform an analysis of a large patient pool to identify current trends and tendencies as well as possible risk factors for complications and early implant failure.We performed a retrospective analysis of patients referred to the Department of Oral Surgery of the Medical University of Vienna, University Clinic of Dentistry between January 2016 and November 2018. First, we evaluated subject characteristics (e.g., demographics, systemic conditions, medication). We then analyzed indications for implant placement (single-tooth gap, extended gap, distal extension, edentulous jaw), implant parameters (length, diameter, type, material), the timing of surgery (immediate, early, late) as well as the exact surgical procedures (e.g., bone augmentation, computer-aided navigation). Finally, we assessed postoperative complications (hematoma, local infection, swelling, nerve damage) as well as early (i.e., before loading) implant failures.A total of 1,132 patients (16u201390 years, mean 50.6 u00b1 16.5 years, 55.4% female, 19.3% smokers) received 2,413 implants. The majority of patients had 1 implant (n = 525, 46.7%). The maximum number of implants per patient was 10. A total of 1,028 implants (42.6%) were used in single-tooth gaps, 379 (15.7%) in extended edentulous gaps, 469 (19.4%) as distal extensions, and 537 (22.2%) in completely edentulous jaws. Implants 11.5 mm in length and 4.3 mm in diameter were the most common (19.6% of all implants). No implants shorter than 8 mm were used, and 86.4% of all implants were between 3.5 and 4.5 mm in diameter. A total of 1,879 (77.87%) implants were placed late (i.e., more than 6 months after first edentulousness) and 732 implants (30.3%) were supported by an augmentative measure. Computer-aided navigation was used for the placement of 226 implants (9.4%). A total of 71 patients (6.27%) reported a postoperative complication. Early implant failure occurred in 16 implants (0.7%).The data show a largely conservative approach to implant dentistry, as evidenced by the absence of short implants, the late time point of surgery, the low prevalence of computer-aided navigation as well as the reservation of bone augmentation for cases where they were indispensable. Our findings highlight a trend shift towards single-tooth replacements, similar to the recent literature. However, our data show a significantly lower prevalence of augmentative measures than comparable studies.

Part II- Peri-implantitis and Late Implant Failures written by Abitbol Jeremy and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background : Implant failure is based on clinical and radiographic information which is a clear and easy endpoint to study and report. The only factor to discuss may be where the cut-off time-point should be placed after implant surgery, separating u201cearlyu201d from u201clateu201d implant failures, resulting into either slightly under- or over-estimation of the two different observations. No obvious trend of increasing implant failure rates over time has been observed yet, much attention has lately been focused on mucosa health and bone loss at the implants, referred to as u201cperi-implantitisu201d. It can be observed that available inclusion parameters for diagnosis of peri-implantitis show an obvious variation in the present literature, and it would be of value to further analyze and report the problems with peri-implantits and implant failures in another larger patient groups in routine practice. Aim :The aim of the present study was to report problems with peri-implantitis and late implant failures in a large private implant referral clinic where patients have been treated on a routine basis over a period of time. The aim was also to analyze the impact of different clinical and patient factors over time with regard to clinical observations related to peri-implantitis, surgery related to peri-implantitis and late implant failures.Material and Methods :A total of 1 017 patients were consecutively provided with 3 082 implants with an anodized surface between 2000 and 2011. All patients with three events of problems were identified; u201cperi-implantitisu201d, u201csurgery related to peri-implantitisu201d and u201clate implant failuresu201d. A logistic multivariate analysis was performed to identify possible factors with an association to the three events.Results :Altogether, 66 patients (92 operations) and 30 patients (34 operations) were identified with u201cperi-implantitisu201d and u201csurgery related to peri-implantitisu201d after first year in function. The statistical analyses identified five and three clinical parameters significantly associated to the two events, respectively. Two-stage surgical technique (with GBR technique; HR1.82; 95% CI: 1.32 u2013 2.52) and immediate grafting at implant surgery (HR 3.34; 95% CI: 1.06-10.54) were the factors with the highest risk associated to these two events, respectively. Risk of peri-implantitis increased by year of inclusion from year 2000 (HR 1.28; 95% CI; 1.16-1.41). u201cLate implant failuresu201d were associated to u201csmokingu201d (HR 2.11; 95% CI: 1.26-3.55), u201ctwo-stage surgeryu201d (with immediate grafting; HR 1.67; 95& CI: 1.11 u2013 2.59) and u201ctype of implantu201d (NobelActive CC; HR 2.48; 95& CI: 1.05 -5.85).

Download or read book Factors Associated with the Failure of Silicone Gel-filled Breast Implants written by Julie Lynn Cross and published by . This book was released on 1997 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the systemic health consequences of silicone gel-filled breast implants have been explored in several large studies, little attention has been placed on factors associated with implant failure (defined as silicone gel on the outside of the implant and commonly referred to as implant rupture). This study explores woman-specific and implant-specific characteristics potentially associated with silicone breast implant failure. The study population consists of 441 women (807 implants) who received MRI examination to diagnose the integrity of their implants (i.e., failed versus intact) between 1992 and 1995 at the UCSD MRI Institute and who responded to a mailed survey in 1996 (79% response rate). Information included the woman's demographic characteristics and personal factors. Medical records provided information about the patient's implants and her implant surgery. Multivariate analysis using the Generalized Estimating Equation (GEE) approach was conducted in order to control for confounding and simultaneously take into account the correlation between factors from two implants within the same woman. Thirty percent of the implants had failed. Meme ME polyurethane-coated implants were identified as having a much greater risk of failure than other implants (86% compared to 27%), and failure occurred in this sub-group at a much younger implant age. Among non-Meme ME implants, increasing age and having had a previous implant were strong predictors of implant failure. Implants placed in the sub-muscular position were at higher risk of failure compared to sub-glandular implants, and smaller implants were more likely to fail than larger ones. Wearing a bra during exercise (always or most of the time) appeared to increase the risk of failure if the implants were sub-glandular or hard. Hardness was a risk factor for implant failure, but only among women who wore a bra during exercise. The risk of failure for a "typical" patient with a 10-year old implant was estimated to be 17%. The results of this study offer guidance to women with breast implants and their health care providers who are questioning their risk of silicone breast implant failure

Download or read book Multifactorial Analysis of Implant Removal- a Retrospective Study of 19 Year Data written by Anastasiya Petrovska and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction: Dental implants have become a popular choice for replacing missing teeth. It is estimated that every year, over two million implants are placed throughout the world. However, dental implants may exhibit immediate or delayed complications that could lead to implant failure. The aim of this study was to explore the factors coincidental with removal of failed implants at the UCSF Postgraduate Periodontology Clinic (PGPC) by reviewing electronic health records (EHR) for the last 19 years.Methods: EHR data from Axium were searched for the dental code D6100 (implant removal) from January 2001 - April 2019. Furthermore, code D7140 (simple tooth removal) was used to include cases that were suspected to be misclassified. Inclusion criteria was focused on patients who had dental implant(s) removed and had sufficient records for analysis. Patient and surgical data were gathered from dental records and analyzed. Exclusion criteria focused on patient data that was incomplete or not accessible.Results: Upon review of 3,426 simple tooth extractions and 81 implant explantations, it was determined that 114 implants were explanted from 88 patients over 19 years. Fifteen patients were removed from the data analysis based on exclusion criteria. Analysis was performed on 73 patients who had a total of 96 implants removed. Of these, 59% of patients had periodontal disease and 32% were smokers. Amongst the medical conditions reviewed, 32% of patients reported cardiovascular disease, 23% had a bone disorder, and 18% had emotional disorders. In terms of the implants, 41 implants were placed in grafted bone; 54% being allograft. Out of 96 implants removed, 58 were late failures and 33 implants failed before loading. Furthermore, we examined the reasons for tooth extractions at sites with subsequent implant failure and found that 6 teeth had endodontic treatment and 3/6 had periapical abscesses. Forty-five percent of cases that had a late failure did not report regular recall and maintenance appointments.Conclusion: Implant failure was coincidental with a history of periodontal disease and other risk factors, such as cardiovascular disease and emotional disorders. A lack of consistent maintenance recalls was frequently found in cases with late implant failure. Not every patient is a good candidate for implant therapy and risk factors have to be carefully evaluated and presented to the patient. This research highlights the need for a systematic evaluation of patients planning to receive implants and the need to inform them of possible complications and risks of implant treatment.
