Abstract

Abstract Objective To assess the behavior of the peri-implant soft margin after immediate implant placement with immediate function, by (1) direct clinical measurements of peri-implant soft margin height and thickness, (2) measurements of peri-implant soft margin height on photographs and (3) the perception of dental professionals regarding the results considering esthetic parameters. Material and method The study included 8 patients with central or lateral incisors indicated to be extracted. Direct measurements of peri-implant soft margin height and thickness were done immediately before extraction (T0) and 1 (T1), 4 (T2), 8 (T3) and 12 (T4) months after the flapless insertion of the implant. Photographs were taken at the same time intervals. A questionnaire was filled in by implantology professionals regarding their visual perception of color and peri-implant soft margin architecture and harmony in the implant region using the photographs obtained at T4. Result The clinical results showed significant changes to the height of the peri-implant soft margin, but the photographic results did not show significant changes for this measurement. The thickness of the attached gingiva was maintained during all the observation period. Of the professionals interviewed, 35.2% noticed an altered peri-implant soft margin color of the implant region, 39.8% noticed a change in the peri-implant soft margin architecture and 12.5% noticed a change in the peri-implant soft margin harmony. Conclusion The soft tissues around immediate implants changed during this period, but did not affect the aesthetic outcome and in the opinion of professionals, the aesthetic results were satisfactory for these cases.

Highlights

Over the last two decades there have been significant developments in implantology, with a revolution in the concepts of rehabilitative treatment
The aesthetics of peri-implant tissues have improved with new implant designs, such as Morse type prosthetic connections, biomaterial grafting techniques, subepithelial connective tissue grafting[7], pre-surgical CT scans[9] and surgical techniques developed for better bone and peri-implant soft margin biological responses[10]
Some factors are crucial for successful treatment with immediate implants in the fresh alveoli of an aesthetic region, such as: the gingival biotype and the thickness of the buccal bone[8,11,17]

Summary

INTRODUCTION

Over the last two decades there have been significant developments in implantology, with a revolution in the concepts of rehabilitative treatment. The aesthetics of peri-implant tissues have improved with new implant designs, such as Morse type prosthetic connections, biomaterial grafting techniques, subepithelial connective tissue grafting[7], pre-surgical CT scans[9] and surgical techniques developed for better bone and peri-implant soft margin biological responses[10]. Among these techniques, flapless surgery to install the implant in the correct three-dimensional position combined with initial stability and the placement of a temporary crown with a suitable contour, are factors that are required for clinical success[8,11]. A subjective evaluation, the perception of dental professionals regarding the results considering esthetic parameters (color, architecture and harmony), was proposed
