Available in PDF, EPUB and Kindle. Book excerpt: Zusammenfassung: AbstractObjectiveTo investigate the survival rate, fracture strength, bending moments, loading to fracture and fracture modes of different designs of zirconia abutments after dynamic loading with thermocycling, and compare these values to titanium abutments.MethodsA total of 80 abutment samples were divided into 5 test groups of 16 samples in each group. The study included the following groups, Group 1: CAD/CAM produced all-zirconia abutments, Group 2: titanium abutments, Group 3 zirconia-abutments adhesively luted to a titanium base, Group 4: prefabricated all-zirconia abutments and Group 5: zirconia-abutments glass soldered to a titanium base. Half the number of samples in each group was exposed to 1.2 million loading cycles (5-years simulation) in the chewing simulator. The samples that survived the artificial aging were later tested for fracture strength in a universal testing machine. The remaining 8 samples of the group were directly tested for fracture strength.ResultsAll samples exposed to the 5-years artificial aging survived except of six samples in one group (Group 1). The surviving samples were later fracture tested in the universal testing machine. The bending moments (Ncm) values were as follow: Exposed groups: Group 1: 94.5 Ncm; Group 2: 599.2 Ncm; Group 3: 477.5 Ncm; Group 4: 314.4 Ncm; Group 5: 509.4 Ncm. Non-exposed groups: Group 1: 269.3 Ncm; Group 2: 474.2 Ncm; Group 3: 377.6 Ncm; Group 4: 265.4 Ncm; Group 5: 372.4 Ncm. Except in Group 1, the values were higher in the exposed groups, although, statistically there was no difference (p>0.05). The one-piece ZrO2-abutment group (Group 1 and Group 4) exhibited lower values, while the two-piece ZrO2-abutment groups (Group 3 and Group 5) showed similar values and fracture modes like the titanium abutment group. The titanium abutment group showed the highest values of bending moments among all groups.ConclusionThe implant-abutment connection area appeared to influence the bending moment value and the fracture mode of the tested abutment groups, and it was found to be the weakest part of an internal connection one-piece zirconia abutment. The titanium base in the two-piece zirconia abutment worked as a substitute for the weakest part of the abutment. Therefore, the titanium base can reinforce the fracture strength of a zirconia abutment

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Various protocols are available to preclinically assess the fracture resistance of zirconia oral implants. The objective of the present review was to determine the impact of different treatments (dynamic loading, hydrothermal aging) and implant features (e.g., material, design or manufacturing) on the fracture resistance of zirconia implants. An electronic screening of two databases (MEDLINE/Pubmed, Embase) was performed. Investigations including > 5 screw-shaped implants providing information to calculate the bending moment at the time point of static loading to fracture were considered. Data was extracted and meta-analyses were conducted using multilevel mixed-effects generalized linear models (GLMs). The Šidák method was used to correct for multiple testing. The initial search resulted in 1864 articles, and finally 19 investigations loading 731 zirconia implants to fracture were analyzed. In general, fracture resistance was affected by the implant design (1-piece > 2-piece, p = 0.004), material (alumina-toughened zirconia/ATZ > yttria-stabilized tetragonal zirconia polycrystal/Y-TZP, p = 0.002) and abutment preparation (untouched > modified/grinded, p

Download or read book Influence of Implant Angulation on the Fracture Resistance of Zirconia Abutments written by Shreedevi Thulasidas and published by . This book was released on 2013 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zirconia-based implant abutments are widely used in prosthetic dentistry. Custom made abutments are utilized to correct for non-ideal implant positions and can successfully accommodate the morphologic requirements of the overlying crown. It was hypothesized that there will be difference in fracture strength and fracture mode of artificially aged zirconia implant abutments supported by implants at varying angulation, when load is applied to failure on overlying zirconia crowns. The implant-abutment-crown assemblies were subjected to steam autoclaving to induce some degree of phase transformation from tetragonal to weaker monoclinic form and to thermo-cycling to artificially age the samples. The effects of loading or occlusal forces applied to a model of implant-abutment-crown assembly with varying geometry of implant alignment was investigated in this study with customized zirconia implant abutments with internally hexed implant and overlying zirconia crowns loaded to fracture. Construct design and loading angulations were selected to simulate mouth conditions as closely as possible. Results showed that fracture strength of zirconia abutments was affected by the variation in the angulation of the implant. Aging did not seem to play a role in the fracture strength.
Book Synopsis The Use of Titanium Dental Implants Vs Zirconium Dioxide Dental Implants in Esthetic Zone. Systematic Review by : Juan Carlos Centeno
Download or read book The Use of Titanium Dental Implants Vs Zirconium Dioxide Dental Implants in Esthetic Zone. Systematic Review written by Juan Carlos Centeno and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: The use of zirconium dental implants for esthetic purposes seems to have a promising future due to similar survival rates to titanium implants. Other added mentioned proprieties are white color, the small level of bacterial adherence and the high resistance of the material. Aim/Hypothesis:The main aim of this systematic review was to evaluate the zirconium oxide implants success and survival rates (ZrO2) versus the titanium implants (Ti) in the esthetic area.Materials and Methods:This Systematic review was registered at PROSPERO with the reference CRD42015019546. Clinical trials that evaluated zirconium oxide implants were searched in seven electronic databases (PubMed, Lilacs, Science Direct, Cochrane Collaboration, Evidence Based Dentistry (EBD), Journal of Evidence-Based Dental Practice (JEBDP), NHS Evidence) till November 2016 and were included according to pre-established inclusion criteria. A manual search was performed on the bibliography of the collected articles, and the authors were contacted for additional references. Success and survival rate for titanium implants (Ti) was compared with the zirconium oxide implants success and survival rate (ZrO2). The quality of the included articles was evaluated using the Critical Appraisal Skills Programme (CASP) criteria, thus being analyzed at both study and outcome level.Results:Seventeen articles were included and the results obtained after calculating the data from each study, in which the zirconium oxide dental implants (ZrO2) location (maxilla or mandible, anterior or posterior) is described. Number of patients: 1057. Number of implants of ZrO2: 1916. Survival: 95%. Follow-up Mean: 32 months (2.6 years). In order to analyze the information about the esthetic area, the studies which did not describe the placement of the zirconium oxide implants in the anterior area (ZrO2) were discarded, only implants placed from 14 to 24 and 34 to 44 (esthetic area) were accounted for: 486 ZrO2 implants. Of the included studies only two were randomized controlled trials; twelve prospective trials and three retrospective studies. Several methodological limitations on the collected articles and debated in this review. The overall survival rate of the zirconium oxide implants of one and two pieces resulted in 95%. Conclusions and Clinical implications: Although the available scientific evidence base is and at considerable risk of bias, from the available data it is possible to conclude that zirconia dental implants could be used in esthetic zone with 95% survival. The different study designs and methodology make difficult to present an overall conclusion regarding the efficacy of ZrO2 implants in maintaining crestal bone levels and periimplant soft tissue health. Further long-term, randomized controlled trials with a standard methodology are needed.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background (500)Despite biocompatibility and excellent clinical outcome of titanium implants, a growing interest for an alternative implant material is noticeable. This is mostly due to patient-specific requests for metal-free treatment and concerns about adverse reactions titanium particle corrosion. Therefore, manufacturers are increasingly introducing zirconia implants with different features and designs. While most systems offer one-piece implant design, little is known about the applicability and features of two-piece implants.Aim of the study (300)This review aimed to summarize the preclinical knowledge about two-piece zirconia implant systems. Focus was given on design features, mechanical resistance of the implants and of the implant-restoration complex as well as peri-implant tissue response.Material and Methods (1000)An electronic search of the literature until March 2017 was performed to identify all articles related to preclinical research on two-piece zirconia implant systems. The search was conducted using MEDLINE (National Library of Medicine), Pubmed without restrictions concerning the date of publication. The search terminology included: zirconia implant, two-piece, mechanical properties, fracture resistance, strength, osseointegration, bone-to-implant contact, soft tissue, histology, histomorphometry (connecting different keywords with AND, OR). Hand-searching of the bibliographies of all full-text articles and related reviews, selected from the electronic search, was also performed. The literature search was limited to only English language articles. References appraised in related systematic reviews were also considered.Results (1000)Of the initially-identified 1026 titles, 58 papers were selected for full-text evaluation. After exclusion 53 articles, a total of 6 article were finally selected and analysed. The mechanical resistance was evaluated in 4 studies, where a clinical situation of implants placed in the anterior region was simulated. Interestingly, most studies used titanium abutment screws for evaluation. Irrespective of connection type (screw- or cement-retained), implant fractures were mostly reported in the implant-abutment connection, with the weakest component to be abutment screw, abutment and implant, respectively. In general, two-piece zirconia implant systems showed higher failure rates and lower resistance than one-piece zirconia implants as well as titanium implants.Peri-implant tissues were evaluated in 2 studies. Regardless of implant type (one- or two-piece), a significant marginal bone loss was recorded 6months after placement (0.19-1.11mm). The height of buccal peri-implant mucosa and bone-to-implant contact ranged, respectively, between 2.64-3.03mm and 78.6-87.9% with no statistically significant differences at follow-up evaluations.Conclusion and Clinical implications (500)Irrespective of connection type and the design, two-piece zirconia implants show sufficient strength to withstand normal forces applied in the anterior region. Hard and soft tissue response around two-piece zirconia implants seem to be similar to one-piece implants as well as titanium implants. Although they have the potential for clinical application, the limited knowledge about two-piece zirconia implants does not support their clinical application yet.
