radiographic Differences studying in Autogenous tooth bone graft in the context of immediate implantation Using cone-beam computed tomography

Abstract

Background: Immediate implantation is very important in many cases cause its benefits.  . Using bone grafts with immediate implantation is very important as well in a lot of cases to  reduce bone resorption and enhance radiographic density of alveolar bone surrounding the implant.

The aim of this study: the aim of the study was to evaluate the bone resorption and radiographic bone density changes  in Autogenous Tooth Bone Graft  (AUTOBT) in immediate implantation using CBCT.

Materials and methods: 11 implants were immediately  inserted after extraction. the gap between the implant and the bone walls were filled with  Autogenous tooth bone graft (AUTOBT). Vertical and Horizontal resorption and radiographic bone density changes of the alveolar socket were evaluated after 6 months after immediate implantation using cone beam computed tomography (CBCT). linear Radiographic subtraction technique in (CBCT) were used to evaluate the radiographic bone density changes.

Results:. after 6 months after immediate implantation there was a mean of vertical alveolar bone resorption 0.99  ±(0.28) mm and a mean of horizontal  alveolar bone resorption 0.58 ± (0,11) mm. Mean radiographic bone density change was( -34.18 pixels ) .

Conclusions: using Autogenous tooth bone graft (AUTOBT)  with immediate implantation reduce the alveolar bone dimensional changes post implantation in the horizontal and vertical planes but it was not able to prevent it completely. AutoBT graft reconfigures and new bone formed in the region of the graft with a good radiographic density.
