Objectives Working Group 2 was convened to address topics relevant to prosthodontics and dental implants. Systematic reviews were developed according to focused questions addressing (a) the number of implants required to support fixed full‐arch restorations, (b) the influence of intentionally tilted implants compared to axial positioned implants when supporting fixed dental prostheses (FDPs), (c) implant placement and loading protocols, (d) zirconia dental implants, (e) zirconia and metal ceramic implant supported single crowns and (f) zirconia and metal ceramic implant supported FDPs. Materials and methods Group 2 considered and discussed information gathered in six systematic reviews. Group participants discussed statements developed by the authors and developed consensus. The group developed and found consensus for clinical recommendations based on both the statements and the experience of the group. The consensus statements and clinical recommendations were presented to the plenary (gathering of all conference attendees) and discussed. Final versions were developed after consensus was reached. Results A total of 27 consensus statements were developed from the systematic reviews. Additionally, the group developed 24 clinical recommendations based on the combined expertise of the participants and the developed consensus statements. Conclusions The literature supports the use of various implant numbers to support full‐arch fixed prostheses. The use of intentionally tilted dental implants is indicated when appropriate conditions exist. Implant placement and loading protocols should be considered together when planning and treating patients. One‐piece zirconia dental implants can be recommended when appropriate clinical conditions exist although two‐piece zirconia implants should be used with caution as a result of insufficient data. Clinical performance of zirconia and metal ceramic single implant supported crowns is similar and each demonstrates significant, though different, complications. Zirconia ceramic FDPs are less reliable than metal ceramic. Implant supported monolithic zirconia prostheses may be a future option with more supporting evidence.

The results of this prospective two-center study demonstrate that titanium implants with a modified SLA surface can predictably achieve successful tissue integration when loaded in full occlusion 21 days after placement. Integration could be maintained without incident for at least 2 years of follow-up.

Transmucosal healing of two-piece implants is as successful as the submerged healing mode with respect to tissue integration and patient satisfaction within the first 12 months after IP.

Purpose:To perform a systematic review on studies assessing clinical outcomes in patients rehabilitated with complete-arch fixed implant-supported prostheses according to the time of loading. Materials and Methods: Data obtained from patient and clinical outcomes, as implant failure, success rate, survival rate, biological complications, technical complications, mechanical complications, and marginal bone loss, were included on this review. The search was performed on databases PubMed, Scopus, and Cochrane. Cochrane Collaboration tool was used to assess the risk of bias of randomized controlled studies, and an adapted version of Newcastle-Ottawa scale was used for observational studies. All data were tabulated according to the time of loading: (1) immediate restoration/loading, (2) early loading, and (3) conventional loading. Results: From a total of 4027 studies identified through the three databases, six of them were randomized controlled trials, five of them were prospective observational studies, and another five were retrospective observational studies. In total, 5954 implants, 1294 patients and 1305 full-arch fixed implant-supported prostheses were included in this review. There was a wide heterogeneity among clinical studies regarding the study design and treatment procedures. Thus, pooled estimates were not performed in order to avoid potential biases. The methodological assessment by the Modified Newcastle-Ottawa scale showed a moderate quality of observational studies. Regarding the RCTs studies, all of them presented at least one element of bias according to the Cochrane Collaboration tool for assessing risk of bias. Conclusion: There is evidence of high survival-success implant rate (95-100%) for either loading protocols (immediate restoration/loading, early loading, and conventional loading). However, careful attention must be taken by clinician when interpreting the results reported in clinical studies. Future studies should be performed using standardized methodology in order to determine the true predictability regarding immediate, early, and conventional loading protocols.
