Summary

Three-unit implant-supported prostheses using two or three implants show similar survival and success rates. This study found comparable clinical outcomes for posterior dental restorations in the short to medium term.

Background:

Partially edentulous posterior regions present unique restorative challenges.
Fixed partial prostheses offer a solution for replacing missing teeth.
Implant-supported restorations require evaluation of long-term clinical performance.

Purpose of the Study:

To compare clinical outcomes of three-unit fixed prostheses.
To evaluate restorations supported by two versus three implants.
To assess posterior implant-supported restorations in the maxilla and mandible.

Main Methods:

Retrospective study comparing two-implant (group 1) and three-implant (group 2) supported prostheses.
Outcome measures included survival, success rates, marginal bone loss, and complications.

Statistical analysis included two-way ANOVA and independent t tests (P < .05).

Main Results:

100% survival rate in both groups over 52-58 months follow-up.
Success rates were 82% (group 1) and 86% (group 2).
No statistically significant differences in marginal bone loss or complication rates, though Plaque Index was higher in group 2.

Conclusions:

Two-implant supported three-unit prostheses demonstrate comparable clinical outcomes to three-implant supported ones.
These findings apply to the posterior maxilla and mandible in the short- to medium-term.
Further research may explore long-term efficacy and patient-specific factors.
