Clinical Study on Coral Hydroxyapatite Combined with Biological Collagen Material in Socket Preservation

doi:10.13701/j.cnki.kqyxyj.2016.09.021

Abstract

Abstract: Objective: To study the clinical effect of coral hydroxyapatite combined with biological collagen material in socket preservation. Methods: Thirty patients were assigned into two groups in a randomized controlled clinical trial. Experimental group: socket preservation with coral hydroxyapatite combined with biological collagen material in the extraction socket. Control group: conventional treatment after tooth extraction. All the patients came back after 6 months since tooth extraction, and the height and width of the alveolar ridge were measured to observe the socket healing condition. The t-test was used to analyze the variations between the experimental group and the control group. Results: In the experimental group, the gingival color and shape were in coordination with the adjacent tooth. Whereas the control group showed alveolar ridge absorption and atrophy with decreased height and notably narrowed width. The mean value changes of alveolar ridge height, width and gingival were statistically significant different between two groups (P＜0.05). Conclusion: Coral hydroxyapatite combined with biological collagen material can preserve the bone quantity after tooth extraction for implant prosthesis and they were suitable materials for socket preservation.
