Abstract

Purpose:The present study aimed to evaluate the long-term stability of esthetic outcomes of soft tissue around maxillary anterior single-tooth implants after 10-to-12 years of loading.Methods:Patients who had been treated for single-tooth implants in the anterior maxilla between February 2000 and July 2002 were invited to participate in the study. All implants had been placed according to delayed implant placement and conventional loading protocols without any connective tissue graft or papilla preservation flaps. Pink Esthetic Score (PES) was rated using standardized clinical photographs to assess the esthetic outcomes of the implant treatment at the time of crown placement and at time of follow-up examination which was at least 10 years after the crown placement.Results:A total of 19 patients were included. The mean score of PES was 11.63 (SD 1.61; range 7-14) at baseline. After 10-to-12 years of function, a mean PES score of 11.05 (SD 2.09; range 6–14) was recorded. No significant differences were found in the esthetic outcomes, categorized based on clinically relevant levels, between the baseline and follow-up session (p>0.05).Conclusion:Within limitation of the present study, it can be concluded that the esthetic outcomes of soft tissue around the maxillary anterior single-tooth implants placed using conventional implant placement technique remained stable in the long-term.

Highlights

Single-tooth replacement in the anterior maxilla using implant-supported fixed prosthesis is a widely accepted treatment modality
The size of interproximal papilla is a crucial factor in the overall esthetic assessment, several other parameters such as, but not limited to, color, form, and level of peri-implant soft tissue are responsible for an acceptable esthetic appearance
Pink esthetic score (PES), developed by Furhauser et al, is one of these instruments that has been widely used in the dental literature to assess the esthetic outcomes of implant therapy, and it has been shown to be a reproducible instrument to assess the esthetic outcomes of soft tissue around implant-supported restorations [6]

Summary

Introduction

Single-tooth replacement in the anterior maxilla using implant-supported fixed prosthesis is a widely accepted treatment modality. The classical success criteria of dental implants are mainly focused on osseointegration and radiographic bone loss. These classical criteria might not be sufficient when evaluating the success of implants placed in esthetically demanding areas, where adequate esthetic appearanceis considered to beof paramount importance for the overall treatment success. Pink esthetic score (PES), developed by Furhauser et al, is one of these instruments that has been widely used in the dental literature to assess the esthetic outcomes of implant therapy, and it has been shown to be a reproducible instrument to assess the esthetic outcomes of soft tissue around implant-supported restorations [6]
