Evaluación estética y funcional del provisional acrílico ferulizado posterior a exodoncia y regeneración ósea guiada en zona anterior.

Abstract

Introduction: Immediate provisionalization after tooth extraction and bone regeneration aims to preserve anterior alveolar architecture. Objective: To retrospectively evaluate the aesthetic and functional outcomes of splinted acrylic provisional restorations after tooth extraction and guided bone regeneration in patients treated at the Teaching University T0, T1, and T2. Materials and Methods: A retrospective study of 30 patients was conducted. Aesthetic performance (WES), gingival aesthetics, mechanical complications, and surface integrity were assessed using serialized photographic analysis. Data were analyzed with Friedman and Wilcoxon tests (α=0.05). Results: WES increased significantly from a median of 6.0 (T0) to 8.0 (T2) (p<0.001). Gingival aesthetics improved from 7.0 (T0) to 7.5 (T1) (p=0.020) and stabilized at 8.0 at T2 (p=0.244). Connector fractures were the main mechanical complication (30.0%). Surface degradation was controlled, with 33.3% visible biofilm in T2. Conclusion: Splinted acrylic provisionals provide excellent aesthetic outcomes and early gingival stability, though manual fabrication shows susceptibility to connector fractures and moderate plaque accumulation over time.
