Summary

Occlusal force on posterior single implants increases over time, while force on opposing natural teeth decreases. Periodic occlusal adjustments are crucial for implant-supported prostheses.

Background:

Single posterior implants are common restorations.
Understanding occlusal forces is vital for long-term implant success.
Natural dentition undergoes continuous occlusal changes.

Purpose of the Study:

To evaluate changes in occlusal contact force on single posterior implants.
To assess the impact of implant restoration on opposing natural teeth.
To analyze these changes at 3- and 6-month intervals post-insertion.

Main Methods:

Prospective cohort study of 21 patients with single posterior implant restorations.
Occlusal analysis using T-Scan computerized system.
Measurement of Percentage of Force on Implant crowns (POFI) and contralateral teeth (POFT).

Main Results:

POFI significantly increased at 3 and 6 months compared to baseline.
Significant differences in POFI were observed between 3 and 6 months.
POFT significantly decreased at 3 and 6 months compared to baseline.

Conclusions:

Occlusal contact intensity on implant prostheses gradually increases post-insertion.
Single posterior implants reduce the occlusal force on the contralateral arch.
Regular occlusal adjustments are necessary to manage dynamic occlusal forces.
