THE OVERALL ESTHETIC ASSESSMENT OF ANTERIOR SINGLE-TOOTH IMPLANT RESTORATION: MODIFIED OBJECTIVE CRITERIA

Abstract

Objectives: The aim of this study was to observe the correlation of esthetic outcomes of single-tooth implant restoration when using Pink Esthetic Score/White Esthetic Score and the new modified assessment (Modified Objective Criteria; MOC) Materials and Methods: This crossectional retrospective study, up to 5 years, recruited 26 patients who single implant in maxillary central incisor area was placed. All the implants were recalled. Demographic data, intraoral photograph, dental model, periapical radiograph and CBCT were taken. One examiner assessed the esthetic outcomes by using PES/WES and MOC (gingiva, prosthesis and bone foundation) with 2 weeks between each evaluation. The score of both groups were analyzed by using K-mean cluster analysis. ANOVA was used to observe the different mean score among clusters, which 0.05 was the significant level. Results: All the recalled implants were found in healthy status. The mean PES/WES was 15.7 ± 1.9 (maximum possible = 20), whereas the mean MOC was 30.7 ± 3.9. The K-mean cluster analysis could categorized the data into 3 clusters namely excellent, medium and divergent cluster, which gingiva and bone foundation score could be significantly divided, however, prosthetic part could not. Conclusions: Combining the bone assessment into esthetic evaluation could presented the esthetic outcome differently from previous routine. The divergent group should be further observed the sustainability of esthetic.
