Immediate single implant placement and loading in the aesthetic zone with a novel dental implant: a 1-year prospective single cohort study

Abstract

OBJECTIVE: This prospective single-cohort study aimed to evaluate the clinical and radiological performance of a novel dental implant positioned in post-extraction sockets in the anterior zone of both jaws and immediately loaded after 1 year in function.MATERIALS AND METHODS: Patients requiring single implant in the anterior zone were treated between January and March 2019 and followed for at least 1 year of function. Minimum values of 35 Ncm or 64 ISQ were required to perform immediate loading. Screw-retained zirconia-based single prostheses were delivered after the healing period. Patients were followed up for 1 year after definitive prosthesis placement to determine implant and prosthetic survival rate, marginal bone loss (MBL), insertion torque, and ISQ values.RESULTS: 40 implants (BoneLevel X, Straumann AG) were positioned in 60 patients. None of the positioned implants failed accounting for an implant survival rate of 100 %. No definitive prostheses failed to result in a 100% prosthetic success rate. Mean MBL was 0.6 mm ± 0.4 mm. Mean overall insertion torque was 58.9 ± 13.8 while mean overall ISQ at implant placement was 72.3 ± 8.1.CONCLUSION: Within the limitations of the present prospective single-cohort study, the investigated clinical and radiological performance of the novel dental implant placed in the anterior zone seems to be a reliable treatment option.
