The study focused on the survival of the restoration (in situ criterion) and the success of the ceramic veneers (no defect). MATERIALS AND METHODS: Seventy-five patients with a maximum of two missing teeth and an antagonistic dentition were treated at the Department of Prosthodontics, University of Goettigen, with 99 posterior FPDs. Fifty-one specimens (experimental group) were veneered with an experimental ceramic suitable for titanium and zirconia frameworks (thermal expansion coefficient [TEC]: 8.5 microm/m K); 48 restorations (Ceram-S group) were veneered with a commercially available low-fusing ceramic optimized for zirconia frameworks (TEC: 9.5 microm/m K). All restorations were luted with zinc-phosphate cement. Statistical analysis was performed according to the Kaplan-Meier method; time-dependent success rates of the different types of ceramic veneers were analyzed using the log-rank test. RESULTS: Seven restorations were lost: 4 due to technical complications and 3 due to biologic complications. The overall survival rate after 48 months was 94% (Kaplan-Meier analysis). Twenty-three events required clinical intervention for restoration maintenance: 13 ceramic veneer chippings (polishing), 6 losses of retention (recementation), 3 caries lesions (filling therapy), and 1 loss of vitality (endodontic treatment). Between the two groups of veneering materials, no significant difference in the probability for success was determined (log-rank test, P=.81). CONCLUSIONS: Within a mean observation period of 4 years, sufficient survival rates for zirconia-based posterior FPDs could be verified. The main complications included fracture of the ceramic veneering material and decementation, which occurred mainly in the mandible."],["dc.identifier.pmid","20305852"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6042"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61265"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","0893-2174"],["dc.relation.orgunit","Universitätsmedizin Göttingen"],["dc.rights","Goescholar"],["dc.subject.ddc","610"],["dc.subject.mesh","Adult"],["dc.subject.mesh","Aged"],["dc.subject.mesh","Dental Restoration Failure"],["dc.subject.mesh","Denture Design"],["dc.subject.mesh","Denture, Partial, Fixed"],["dc.subject.mesh","Female"],["dc.subject.mesh","Follow-Up Studies"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Male"],["dc.subject.mesh","Middle Aged"],["dc.subject.mesh","Prospective Studies"],["dc.subject.mesh","Survival Analysis"],["dc.subject.mesh","Tooth, Artificial"],["dc.subject.mesh","Treatment Outcome"],["dc.subject.mesh","Zirconium"],["dc.title","Prospective evaluation of zirconia posterior fixed partial dentures: four-year clinical results."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

To evaluate the effects of different abutment geometries in combination with varying luting agents and the effectiveness of different cleaning methods (prior to re-cementation) regarding the retentiveness of zirconia copings on implants. MATERIALS AND METHODS. Implants were embedded in resin blocks. Three groups of titanium abutments (pre-fabricated, height: 7.5 mm, taper: 5.7; customized-long, height: 6.79 mm, taper: 4.8; customized-short, height: 4.31 mm, taper: 4.8) were used for luting of CAD/CAM-fabricated zirconia copings with a semi-permanent (Telio CS) and a provisional cement (Temp Bond NE). Retention forces were evaluated using a universal testing machine. Furthermore, the influence of cleaning methods (manually, manually in combination with ultrasonic bath or sandblasting) prior to re-cementation with a provisional cement (Temp Bond NE) was investigated with the pre-fabricated titanium abutments (height: 7.5 mm, taper: 5.7) and SEM-analysis of inner surfaces of the copings was performed. Significant differences were determined via twoway ANOVA. RESULTS. Significant interactions between abutment geometry and luting agent were observed. Temp Bond NE showed the highest level of retentiveness on customized-long abutments, but was negatively affected by other abutment geometries. In contrast, luting with Telio CS demonstrated consistent results irrespective of the varying abutment geometries. Manual cleaning in combination with an ultrasonic bath was the only cleaning method tested prior to re-cementation that revealed retentiveness levels not inferior to primary cementation. CONCLUSION. No superiority for one of the two cements could be demonstrated because their influences on retentive strength are also depending on abutment geometry. Only manual cleaning in combination with an ultrasonic bath offers retentiveness levels after re-cementation comparable to those of primary luting."],["dc.identifier.doi","10.4047/jap.2014.6.3.233"],["dc.identifier.isi","000338750900012"],["dc.identifier.pmid","25006388"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10638"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33222"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Korean Acad Prosthodontics"],["dc.relation.issn","2005-7814"],["dc.relation.issn","2005-7806"],["dc.rights","CC BY-NC 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/3.0"],["dc.title","Evaluation of removal forces of implantsupported zirconia copings depending on abutment geometry, luting agent and cleaning method during re-cementation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

This retrospective study evaluated the outcome of implant-retained overdentures (IODs) after 5-19 years of clinical function. MATERIALS AND METHODS. A retrospective analysis of patient files was performed referring to 27 patients who received 36 IODs with 3 different bar designs (group A=prefabricated round bars, n=7; group B=one-piece anterior milled bars, n=20; and group C=two bilaterally placed milled bars, n=9) in the mandible (n=24) and/or in the maxilla (n=12). The analysis focused on the survival and success rates (according to Kaplan-Meier) of the implants and prostheses. Technical complication rates for each type of restoration were analyzed and compared via one-way ANOVA and the Chi-squared test. The prevalence of peri-implantitis (radiographic bone loss >= 3.5 mm) was evaluated by digital analysis of panoramic radiographs taken postoperative (baseline) and after 5-19 years of clinical function (follow-up). RESULTS. The mean observational time was 7.3 years. The survival rates of the prostheses and implants were 100% and 97.7%, respectively. Technical complications occurred more frequently in group A (mean: 3.5 during observational time) than in the other two groups (B: 0.8; C: 1.0). However, this difference was not statistically significant (P=0.58). Peri-implantitis was diagnosed for 12.4% of the implants in 37% of the patients. CONCLUSION. Bar-retained IODs are an adequate treatment option for edentulous jaws. These restorations may exhibit high implant/prosthesis survival rates (>97%), and a limited incidence of technical complications after a mean observational period of >7 years. Nevertheless, peri-implantitis was identified as a frequent and serious biological complication for this type of reconstruction."],["dc.identifier.doi","10.4047/jap.2015.7.4.338"],["dc.identifier.isi","000360420400010"],["dc.identifier.pmid","26330982"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13576"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36386"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Korean Acad Prosthodontics"],["dc.relation.issn","2005-7814"],["dc.relation.issn","2005-7806"],["dc.rights","CC BY-NC 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc/3.0"],["dc.title","Implant-supported overdentures with different bar designs: A retrospective evaluation after 5-19 years of clinical function"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
