Assessment of Horizontal Bone Gain Using Patient Specific Titanium Sheet: a Novel Protocol for Treatment of Horizontal Deficiency in the Anterior Maxilla (Case Series Study ).

The successful use of dental implants for replacing missing dentition requires adequate available bone in the treatment planning phase and inserting the implant in the correct 3D position to achieve good esthetic and function outcomes.(Rieder et al., 2016)

The horizontal deficient anterior maxilla presents considerable challenges for surgical and prosthetic reconstruction. Inadequate alveolar ridge width caused by trauma , infection, congenitally missing teeth or resorption subsequent to dental extractions hampers dental implant placement (Aghaloo & Moy, 2007)

Avariety of bone augmentation technigue have been described to enhance the bone volume of the deficient implant recipient site such as autogenous bone graft ,synthetic bone graft ,distraction osteogenesis ,ridge splitting, guided bone regeneration(Rakhmatia, Ayukawa, Furuhashi, & Koyano, 2013)(Gulinelli et al., 2017)

Autograft remain the gold standard with the capacity to regenerate and forming new bone through its osteogenic ,osteoconductive and osteoinductive properties which can be obtained from chin area (Donos, Mardas, & Chadha, 2008).

Due to the limited availabity of autograft in case of sever resorped ridge ,xenogrft can be mixed to increase the amount of bone applied to the defective area(Monje et al., 2015)
