Evaluation the Effectiveness of Socket-preservation after Extraction by Using Calcium Sulphate Grafts

Abstract

Background and Aim of study: Alveolar ridge preservation procedures have been introduced to protect the alveolar ridge from resorption postextraction and preserving it with adequate height and width, maintain an acceptable ridge contour in areas of aesthetic concern that can be undertaken by preventing alveolar ridge atrophy and maintain adequate dimensions of bone in order to facilitate implant placement and to reach acceptable prosthetical results.

Aim of Study: Evaluate the efficacy of one of the techniques of socket preserving by using Calcium Phosphate grafts with APRF in preventing socket from resorption of the crestal ridge vertically and horizontally after teeth extraction in order to prepare for dental implantation

Materials & Methods: 22 teeth were extracted in 11 patients. 11 socket extraction were grafted with Calcium Phosphate Grafts with APRF after extraction immediately, and 11 socket after normal extraction without adding any graft or material which considered as a control group. horizontal and vertical resorption of the crestal ridge were evaluated after 6 months of extraction in the study and control groups by using CBCT.

Results: after 6 months postextraction there was a mean of vertical alveolar bone resorption 0,93 ± (0,49) mm in the study group and 1,72 ± (0,72) mm in the control group .On the other side, there was a mean of horizontal  alveolar bone resorption -0,78 ± (0,79) mm in the study group and -2,30 ± (0,74) mm in the control group.

Conclusions: Calcium Phosphate Grafts with APRF  reduce the alveolar bone dimensional changes postextraction in the horizontal and vertical planes , but was unable to completely prevent such changes .
