Actual (reported)this study aims to evaluate horizontal bone augmentation achieved at the anterior maxilla using computer-guided cortical shell bone technique and accuracy of fixation of the bone shell away from the atrophic ridge by a calculated distance which is always a challenging step for inexperienced surgeons to fix a cortical shell at the ideal position in the conventional protocol it was never guided to be precisely fixed at the proper position and angulation the problem is if it fixed with insufficient distance with proposed volume loss leads to totally insufficient volume gain for future implant placement also to evaluate the efficacy of the CAD/CAM surgical guide during chin harvesting procedures in reducing the risk of anatomical structure damage and patient morbidity with more accuracy compared with the standard technique. this trial versus free hand conventional cortical shell bone technique both harvested from symphysis area (chin).

a patient-specific guide was used to harvest a chin cortical shell which was also prepared and positioned at the (anterior horizontally atrophied maxilla) recipient site using another patient-specific positioning guide.
the horizontally atrophic anterior maxilla was augmented with a cortical shell technique the bone was harvested from the chin without a patient-specific guide.
