A Radiological Evaluation of Bone Healing in Postextraction Sockets Following Bone Grafting Using Beta-Tricalcium Phosphate and Calcium Phosphosilicate: A Controlled Comparative Study.

BACKGROUND

Healing unbinds a well choreographed array of cellular, physiologic, biochemical, and molecular processes directed toward restoring the integrity and functional capacity of the damaged structures. The rate and degree of healing vary among individuals but is greatest during the first few months or years after tooth loss. Evidence suggests that alveolar bone ridge resorption may be prevented, initially by reconstructive surgical techniques using several materials which are employed at the time of extraction. This droves to the development of bone substitutes materials such as hydroxyapatite, beta tricalcium phosphate (β TCP), and bioactive glasses. These regenerative materials not only act as an osteoconductive scaffold but also interact with the surrounding tissues and impart an osseostimulatory effect.

METHODS

Twenty adult patients who required bilateral removal of homologous tooth, were informed and described regarding post extraction socket grafting using β TCP and CPS followed by covering with Collagen Membrane. Radiographic densitometry evaluation of postoperative visits of immediate; 1st month; 3rd month; and 6th month using orthopantomograph was done.

RESULTS

The Karl Pearson's Correlation coefficient was used to determine the degree of bone density with adjacent bone preoperatively and postoperatively. The statistical evaluation, CPS was more superior to β TCP, with a difference of 58.75 and value showed more significance (<0.0001).

CONCLUSION

This article evaluates radiographically quality and quantity of bone formation in the socket, following extraction and bone grafting using Calcium Phosphosilicate (CPS) and β TCP, it is concluded that the two modalities of treatment were efficient in improving the clinical outcome parameters as well as showed comparable regenerative effects when used in the treatment of "socket grafting" while between them CPS more superior to β TCP biomaterials by Osteogenic properties.
