Abstract

The aim of this study was to compare the conventional healing screw with custom healing screw in terms of maintenance of soft tissue architecture. Twenty-four patients who underwent single tooth extraction and single immediate implant placement were included in the study. Twelve patients were treated with conventional healing screw after immediate implant placement (control group) and 12 were treated with screw-retained custom healing screw (test group). After minimally traumatic tooth extraction, a temporary abutment was fabricated utilizing flowable composite, which adapted to the socket architecture, to serve as a customized healing screw. In order to evaluate soft tissue remodeling in all cases, digital impressions were made before tooth extraction, at implant insertion, at 6 months after insertion, and after placement of the final restorations. After 6 months of the Osseo integrated period, the custom healing screw served successfully as a tooth profile for peri-implant tissue. In cases of implants with conventional healing screw, soft tissue remodeling around the implants is observed, in contrast to cases of custom healing abutments. Correct design of a healing abutment is important for maintaining the emergence contour in cases of immediate implant placement. In our study, a considerable difference was observed between the standard healing screw and customized healing screw. The selection between provisional restoration and customized healing abutment is only based on esthetic considerations.
