Abstract
Aims: 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.
Methodology: This is a randomized controlled clinical study with two arm parallel groups with allocation ratio 1:1, which used CBCT imaging and flapless surgical technique to place implants in fresh extraction sockets and compare the accuracy of implant placement when using computer aided surgical guides and free hand techniques. Accuracy measurements were done using Blusky®1software. A total of 22 patients were diagnosed and selected according to inclusion and exclusion criteria. Each patient received implants was restored at the end of the study with a fixed prosthesis.
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 the mean values 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. While angular deviation mean values in 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 esthetic region and thus the prosthetic aspect.
