Purpose:
This systematic review and meta- analysis aimed to evaluate the occlusion variations in single posterior implant supported fixed prostheses.
Materials And Methods:
The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were followed and the study was registered in the international prospective register of systematic reviews (PROSPERO) platform (CRD42024501657). A systematic search of the PubMed/MEDLINE, Embase, Web of Science, and Cochrane Library databases published until December 2024 was done by 2 independent reviewers, without restriction of language or publication date. A meta-analysis was performed using the R version 4.0.2, considering the significance level P < .05. Quality assessments were performed using the ROBINS-I tool.
Results:
Five studies were included, totaling 150 participants and 146 posterior single implant-supported fixed prostheses evaluated over time. The meta-analyses were performed with different follow-up months to evaluate the means in percentage the occlusal variations: 0,5 months (5,91%); 3 months (7,70%); 6 months (8,29%); 12 months (13,01%); 24 months (14,31%); 36 months (19,41%). Significant difference (P < .05) was presented from 12 months of follow-up.
Conclusion:
Implant-supported prostheses present occlusal variations after installation, with a progressive increase over time, being significant after 12 months of installation. Therefore, careful long-term monitoring of occlusion is essential, with occlusal adjustments being considered when necessary.
