Assessment of horizontal ridge augmentation in anterior mandible using computer guided autogenous cortical shell technique versus free hand technique:
randomized clinical trial
patients with deficient anterior mandible were included in this study where control group patients received free hand harvesting and fixation of cortical shells from the symphysis, while the study group patients received the same protocol using 2 patient specific guides (psg) the first guide used for safe and accurate graft harvesting with the proposed dimensions while the second guide used for shell fixation leaving the desired gap with the recipient site that was filled with a particulate mix of xeno and auto grafts .the first guide was fixed in place allowing for accurate harvesting of the cortical shell of desired dimensions from the symphysis Then; the harvested shell was fixed to the second guide outside the patients mouth using micro screws And this fixation guide was finally secured to its final position using two interlocking wings to lock into the first guide at the surgical site as a verification step for the accuracy of the whole procedure. Finally, the 2 guides were removed after shell fixation to the recipient site in a through and through manner st the proposed planed position.
