It was reported that in 46% of patients, the occlusal load applied to implant prostheses changed within 18 months after prosthesis placement, and almost one-third of these changes took place during the first 6 months.…”

“…Implant-opposing natural teeth are likely to move, and, consequently, cause changes in the provided occlusal contacts over time, which in turn can potentially contribute to noxious forces. Dario 17 reported that in 50% of studied patients, the occlusion of implant-supported fixed prostheses changed within 18 months after placement. Most of the changes occurred within the first 6 months after prostheses insertion.…”

Aim:The aim of this prospective cohort study was to evaluate the postinsertion posterior single-implant occlusion changes at 3-and 6-month intervals using T-Scan computerized occlusal analysis. Materials and methods:A total of 21 patients received single implant, opposed by natural dentition, in posterior regions of the maxilla or mandible (13 premolar, 8 molar) and were finally restored with cemented-retained metal-ceramic crowns. The occlusal contacts were equilibrated according to the implantprotective occlusion concept to develop light contact with heavy occlusion and no contact with light occlusion in maximum intercuspation. The percentage of force applied to the implant crowns (POFI) and contralateral teeth (POFT) was evaluated using T-Scan computerized occlusal analysis at prosthesis insertion, 3-and 6-month follow-up appointments. The data were statistically analyzed using Friedman test and Wilcoxon post hoc test (α = 0.05). Results:The POFI values at the 6-and 3-month follow-up appointments were significantly higher than those at prostheses insertion (p = 0.001 and p = 0.005 respectively). In addition, there were significant differences between the POFI at 3-and 6-month follow-up (p = 0.020). However, the POFT values at 3-and 6-month follow-up appointments were significantly lower than those at baseline (p < 0.001). Conclusion:The intensity of occlusal contacts of implantsupported prostheses opposed by natural dentition gradually Clinical significance: A periodic occlusal adjustment of implant-supported prostheses is necessary to prevent potential overloading from the movement of opposing natural dentition.

Implant treatment has become the treatment of choice to replace missing teeth in partially edentulous areas. Dental implants present different biological and biomechanical characteristics than natural teeth. Occlusion is considered to be one of the most important factors contributing to implant success. Most literature on implant occlusal concepts is based on expert opinion, anecdotal experiences, in vitro and animal studies, and only limited clinical research. Furthermore, scientific literature regarding implant occlusion, particularly in implant-supported fixed dental prostheses remains controversial. In this study, the current status of implant occlusion was reviewed and discussed. Further randomized clinical research to investigate the correlation between implant occlusion, the implant success rate, and its risk factors is warranted to determine best clinical practices.

“…The positional changes of teeth may intensify the occlusal stress on implants. In order to prevent the potential overloading on implants from the positional changes, re-evaluation and periodic occlusal adjustments are imperative (Dario 1995;Rangert et al 1997;Misch 1999a).…”

Due to lack of the periodontal ligament, osseointegrated implants, unlike natural teeth, react biomechanically in a different fashion to occlusal force. It is therefore believed that dental implants may be more prone to occlusal overloading, which is often regarded as one of the potential causes for peri-implant bone loss and failure of the implant/implant prosthesis. Overloading factors that may negatively influence on implant longevity include large cantilevers, parafunctions, improper occlusal designs, and premature contacts. Hence, it is important to control implant occlusion within physiologic limit and thus provide optimal implant load to ensure a long-term implant success. The purposes of this paper are to discuss the importance of implant occlusion for implant longevity and to provide clinical guidelines of optimal implant occlusion and possible solutions managing complications related to implant occlusion. It must be emphasized that currently there is no evidence-based, implant-specific concept of occlusion. Future studies in this area are needed to clarify the relationship between occlusion and implant success.
