Dental Implants Placed in Fresh Human Extraction Sockets Without Osteotomy: A Case Series

Abstract

Objectives: This case series evaluates healing parameters of immediately placed implants in fresh extraction sockets without osteotomies. It examines resonance frequency analysis (RFA) trends and radiographic bone changes from placement to prosthetic restoration. Material and Methods: The study reports on eight patients with 10 implants using a self-tapping, knife-shaped implant with progressive thread design and anatomical healing abutments. RFA values and standardized radiographs were recorded at three time points from placement to prosthetic restoration. Results: Implants were placed in molar, premolar, and incisor sockets. All implants achieved insertion torque greater than 35 Ncm and high ISQ values. The median reported bone remodeling was 0.35 mm from implant placement to definitive restoration. RFA revealed a median of 64 ISQ buccolingually and 74 ISQ mesiodistally at placement, increasing to 76 ISQ buccolingually and 82 ISQ mesiodistally pre-prosthetically. Conclusions: The findings suggest that immediate dental implants placed without osteotomies in select anatomical conditions can achieve successful osseointegration and functional stability. However, given the small sample size, further studies with larger cohorts are necessary to validate these results.
