Summary

This study compares the accuracy of osteotomies positions using patient specific guides for onlay bone shells harvested from the chin then the graft positioning for 3D upper anterior ridge augmentation using patient-specific tooth-supported guide versus free hand technique

Detailed description

In this study the tooth-supported stereolithographic guiding template is proposed to allow accurate onlay grafting of labial and palatal mono-cortical shells simultaneously after harvesting using computer-designed patient-specific surgical osteotomy guide. This customized osteotomy guide should provide accurate harvesting of autogenous bone blocks from chin area which also provides suitable contour with the anterior ridge area. This computer assisted surgery is supposed to help in decreasing the operation time, thus decreasing the devascularization time to the bone graft. Thus, it helps for increased accuracy to increase three-dimensional bone gain and decrease morbidity of donor site while gaining the maximum available bone volume. Tooth-supported graft placement guide provides reproducible and convenient design without the need of high surgical skills as well.

Conditions

• Alveolar Bone Loss

Type	Name	Description
PROCEDURE	3D ridge augmentation using tooth-supported patient-specific guide	In this study computer-designed patient-specific surgical osteotomy guide should provide accurate harvesting of autogenous bone blocks from chin area.Then, graft placement will be done using patient-specific tooth-supported guide in upper anterior deficient ridge and fixation using 2 micro screws labially and one through and through for the palatal shell.
