Evaluating The Efficiency Of Applying beta-tricalcium phosphate (β-TCP) graft in fresh alveolar socket - Post Extraction For Preserving The Alveolar Ridge by means of CBCT technique

الملخص

The aim of this prospective clinical study is to evaluate the efficacy  application  of β-TCP in fresh alveolar socket - Post Extraction on the absorption of the alveolar bone after extraction. In this study, 40 single root teeth were extracted in 32 patients  (21 females and 11 males) from the mandible.  β-TCP applied in the fresh alveolar sockets of (20) teeth (group 1) The remaining 20 teeth (group II) were left to heal spontaneously. Measurements were performed at three periods (immediately after extraction, after three months, and after six months of extraction) using the Ez-3D Plus program on the cross sectional of the alveolar ridge of the CTBT. the measurements were performed in the center of alveolus of the extracted teeth with the aim of studying the changes in height  of the alveolar margin: the measurements were taken from the top of the alveolar ridge to the lower edge of the mandible.

 The results of this study showed statistically significant differences between the averages of the height changes of the alveolar (P >0.05) for all comparisons after (three and six months), the average of height reduction in  β-TCP group was 1.29±0.25 mm and 2.89±0.49 mm in control group while the average of height reduction in  β-TCP group after six months was 1.78±0.32 and 3.93±0.51 in control group.

Conclusion : applying β-TCP in fresh alveolar socket - Post Extraction reduces the absorption of alveolar ridge height. It's recommended to apply β-TCP in the alveolar socket post extraction in the context of alveolar ridge preservation.
