Peri Implant Marginal Bone Height and Bone Density

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the effect of mandibular implant supported removable overdenture on bone height and density and compare it with implant supported fixed overdenture in single mandibular overdenture.

Detailed Description
-----------------
In this study 10 patients will be selected following inclusion and exclusion criteria. In each group 5 patients (each patient will receive 6 implants) will be divided randomly into two groups. Group I patients will receive mandibular implant supported removable overdenture, while Group II will receive mandibular implant supported fixed overdenture. All patients will be given the usual home care instructions about wearing and caring of dentures and opposing arch. Regarding dentures, removal of them at night and cleaning with denture brush and mild soap will be required. Measurements of Bone height and Bone density will be obtained by using Cone Beam Computed Tomography (CBCT). Measurements will be obtained at denture insertion, after 1 month and after 3 months.
