生物可吸收性胶原膜的固定方式对上颌前牙区水平骨增量效果的影响
The influence of bioabsorbable collagen membrane fixation protocols on horizontal ridge augmentation in the maxillary anterior region
摘要
Abstract
Objective To evaluate the influence of bioabsorbable collagen membrane fixation protocols on horizontal ridge augmentation in the maxillary anterior region.Methods A total of 36 patients were enrolled in this retrospective study.One implant was placed in the maxillary anterior region,and simultaneous guided bone regeneration(GBR)surgery was performed.Participants were divided into 3 groups based on different bioabsorbable collagen membrane fixation protocols.Group 1:fixation with titanium pins;Group 2:fixation with absorbable sutures;Group 3:fixation with titanium pins and absorbable sutures.Cone beam computed tomography(CBCT)was performed immediately after surgery(T1)and at six months post-surgery(T2),respectively.The horizontal bone width of the augmented region was analyzed at the implant shoulder(H0)and 2,4,6 mm apical to the implant shoulder(H2,H4,H6).Changes in labial bone width during bone healing were calculated as absolute values(mm)and relative values(％).The incidence of postoperative complications was recorded.Results After six months of bone healing,all groups showed significant bone loss at H0-H6 compared to immediate post-surgery results(P＜0.05).At H2,horizontal bone loss in Group 1 was significantly less than in Group 2(P＜0.05).Group 3 exhibited significantly less horizontal bone loss compared to Group 1 at H0(P＜0.05),and Group 3 showed significantly less bone loss than Group 2 at H0-H4(P＜0.05).There were no significant differences in the incidence of hematoma,wound bleeding,wound dehiscence,or infection among the groups(P＞0.05).Conclusion When implant placement with simultaneous horizontal ridge augmentation was performed in the maxillary anterior region,membrane fixation with titanium pins demonstrated superior results of the augmented region near the implant shoulder compared to fixation with absorbable sutures.However,the combined use of pins and absorbable sutures contributed to achieving better bone augmentation results compared to using either method alone.关键词
