Evaluation of Accuracy in Computer Guided Versus Free Hand Immediate Implant Placement in Fresh Extraction Sockets: a Randomized Controlled Clinical Trial

Abstract

Background: The aim of this study was to compare between computer guided and free hand immediate implant placement in fresh extraction sockets in terms of accuracy of implant positioning.Methods: This is a randomized controlled clinical study, which used CBCT imaging and flapless surgical technique to place implants in fresh extraction sockets. Accuracy measurements were done using BluSky®1software. A total of 22 patients were recruited according to inclusion and exclusion criteria. Results: The mean values at the implant shoulder for implants inserted using computer surgical guides and those inserted using free hand technique in the mesiodistal direction were 0.69 and 1.43mm, respectively. While in the buccolingual direction they were 0.96 and 1.34mm, respectively. At the implant apex in the mesiodistal direction, they were 1.26 and 2.35mm, respectively. While in the buccolingual direction, they were 1.64 and 1.70mm, respectively. For the angular deviation they were 1.57 and 3.18mm respectively in the mesiodistal direction. Whilein the buccolingual direction were 1.29 and 7.76mm, respectively.Conclusions: Accuracy of computer guided immediate implant insertion surpasses the freehand technique in the buccolingual direction in terms of placing Immediate Implants in fresh extraction sockets in maxillary estheticregion and thus the prosthetic aspect.
