TL;DR
This study compares two dental restoration methods for posterior teeth over two years, finding that direct techniques offer better initial aesthetics while semi-direct techniques last longer.
Contribution
The study provides a two-year comparative analysis of direct and semi-direct composite techniques in posterior teeth restorations.
Findings
Direct technique showed better initial aesthetics and surface finish at 6 months.
Semi-direct technique outperformed in wear resistance and marginal integrity after one year.
Both techniques showed progressive deterioration in marginal adaptation over time.
Abstract
Background: Composite restorations are the standard of care for posterior teeth due to their aesthetic properties and conservative nature. However, the choice between direct and semi-direct techniques can influence clinical longevity and performance. Objectives: This study aimed to compare the clinical performance of two restorative approaches: a direct technique and the semi-direct onlay technique in terms of aesthetic quality, surface finish, wear resistance, marginal integrity, and overall clinical efficiency over a two-year period. Methods: A total of 348 composite restorations were placed in 192 patients. Each restoration was evaluated at four timepoints: baseline (T0), 6 months (T1), 1 year (T2), and 2 years (T3). Clinical performance was assessed using standardised 5-point rating scales across the five dimensions. Repeated-measures ANOVA assessed changes over time, while Wilcoxon…
