The clinical effect of concentrated growth factor combined with autogenous bone in the treatment of jaw cyst
Objective To explore the clinical effect of highly concentrated growth factor combined with autog-enous bone in the treatment of apical cyst.Methods 71 patients with jaw cyst who were treated in Jiayuguan Traditional Chinese Medicine Hospital from March 2018 to May 2021 were selected and divided into a study group(n=42)and a control group(n=29)according to different intraosseous fillings and wound coverings.In the study group,a mixture of concentrated growth factor,autogenous bone and Bis-Oss bone powder were filled into the bone cavity.The wound was covered with concentrated growth factor membrane and artificial biofilm.In the control group,only Bis-Oss bone powder was filled into the bone cavity,and the wound was covered with a single artificial biofilm.Intraoperative blood loss,postoperative swelling and pain,incision removal time,wound soft tissue healing and bone formation in the bone defect area were observed in the two groups.Scar scores at 1 week,2 weeks and 1 month after surgery,average bone density HU and keratinized gingival width at 3 months,6 months and 12 months after surgery were compared.Results The amount of blood loss,swelling and pain,incision removal time and scar score in the study group were significantly decreased compared with the control group(P<0.05).The average bone density HU and keratinized gingiva width in the former were significantly increased at 6 months and 12 months after the operation(P<0.05).Its total effective rate was better than that of the control group(P<0.05).Conclusion Concentrated growth factor combined with autogenous bone can promote the repair and regeneration of gingival soft tissue,reduce scar tissue,shorten the healing time of bone defect and induce bone formation in the process of wound healing after jaw cyst extraction.This provides a new and effective surgical treatment of jaw cyst,which is worthy of clinical application and promotion.
