Khoury technique, which employs autogenous bone blocks harvested from the patient, has been widely used for horizontal and vertical ridge augmentation. This method introduces critical limitations, including the technical complexity, morbidity associated with donor site harvesting, such as infection, neurosensory disturbances, and post-operative discomfort This clinical case series aims to demonstrate how customized pours zirconium shell could be an alternative technique for ridge augmentation to overcome the limitations of Khoury shell technique.

Horizontal bone gain
Tomographic evaluation of the horizontal bone gain using CBCT in millimeters , CBCT scans will be performed to assess the amount of bone gain in comparison to the preoperative CBCT scans
6 months postoperatively.
Soft tissue dehiscence
Soft tissue will be evaluated post-operatively at 1, 2, 4, 6, 8, 12, and 16 week recall appointments
Swelling score
Swelling score will be evaluated for one week postoperatively
Customized Zirconia membrane will be used as a non resorbable membrane for horizontal ridge augmentation of deficient posterior mandibular region.
Customized Zirconia membrane will be printed as a porous shell and will be used as a non resorbable membrane for horizontal ridge augmentation of deficient posterior mandibular region.
