Chin area is considered as a suitable donor site for autogenous bone grafts for alveolar ridge reconstruction before dental implantation. Despite the common use of chin bone grafts, some neurosensory deficiency of the of the lower lip, chin area , gingiva and lower anterior teeth may occur. Purpose: Evaluation of neurosensory deficiency of the lower lip, chin area , gingiva and lower anterior teeth following chin bone harvesting for posterior mandibular alveolar ridge reconstruction.

This prospective clinical trial aims to investigate the change of alveolar ridge width after immediate implantation using tow deferent techniques in expanding the alveolar ridge. In this study, 12 patients (9 female,3 male) with narrow alveolar ri dges in the maxilla were treated. 20 dental implants were immediately installed after the expansion procedures of the selected narrow ridges , 10 implants with Bone Spreader technique , and 10 implants with Bone Splitting technique .
The purpose of the present study was to radiologically assess the hard tissue changes around the immediately loaded implants single tooth bioactivated with plasma rich in growth factors ,placed in the mandibular posterior region . Twenty dental im plants placed in 13 patients had at least single edentulous space in the posterior region of the mandible using single stage procedure after bioactivation the implants surfaces with plasma rich in growth factors.
The aim of this clinical study Was to Evaluation success rate of the Bone Augmentation With Simultaneous Dental Implantation using Autogenous Bone Block In Patients With Atrophic Alveolar Ridges . The study was contained 6 cases were augmented Wi th Simultaneous Dental Implantation by applying Autogenous Bone Block technique The height and width was measured by using computerized tomographic C T scan before and after the surgical operation and also resorption after six months.
