Immediate Implant Placement in the Aesthetic Area using Inverted Body-shift Design: A Prospective Clinical Pilot Study.

Abstract

A prospective clinical pilot study was carried out to evaluate a novel macroimplant design with a 12° angled platform. The implant is placed at the center of the socket, optimizing all the alveolar bone. In addition, the prosthetic emergence should be ideal, as it is corrected and emerges through the cingulate area. Twelve patients were enrolled in an immediate implant placement procedure with immediate aesthetic rehabilitation to replace an anterior maxillary tooth, and were treated with inverted body-shift design with 12° angled neck. Only type I sockets according to the Elian classification were considered eligible for the study. There were no implant failures after one year of loading. Regarding the horizontal and vertical hard tissue changes, there was a statistically significant median overall horizontal change of -0.99 mm at 1 mm and of -0.61 mm at 3 mm. On the other hand, stability was observed at 5 mm, since the result obtained was not statistically significant. The median pink esthetic score (PES) at one year of follow-up was 11.5. This implant may be useful in the immediate tooth replacement treatment of maxillary anterior post-extraction sockets, nevertheless, comparative studies with conventional implants should be carried out.
