Study Overview
=================
Brief Summary
-----------------
Mandibular ridge splitting with complete separation of the buccal cortical plate versus Khoury shell technique for horizontal augmentation of atrophic posterior mandible

Official Title
-----------------
Mandibular Ridge Splitting With Complete Separation of the Buccal Cortical Plate Versus Khoury Shell Technique for Horizontal Augmentation of Atrophic Posterior Mandible

Conditions
-----------------
Horizontal Augmentation of Atrophic Posterior Mandible

Intervention / Treatment
-----------------
* Procedure: ridge splitting in group and khoury shell technique in the other group


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patients with atrophic mandible with residual bone width 3 to 4 mm. Both sexes. No intraoral soft and hard tissue pathology No systemic condition that contraindicate implant placement. Exclusion Criteria: • Any pathology in the posterior mandible. Heavy smokers more than 20 cigarettes per day. Patients with systemic disease that may affect normal healing. Psychiatric problems Disorders to implant are related to history of radiation therapy to the head and neck neoplasia, or bone augmentation to implant site.
