Abstract:
The present study aimed to report a technically improved operation on the surgical exposure of labially impacted maxillary canine, elaborating the management of soft tissue to achieve better aesthetic results, and post-treatment periodontal health.
Patients sought orthodontic treatment with unilateral labially impacted maxillary canines were selected in this study. The impacted teeth were assigned to the experimental group and contralateral unimpacted canines were assigned to the control group. The impacted canines were surgically exposed with dissected dental follicle (DF) stitching to muscle and mucosa surrounding the crowns. The gingival index (GI), probing depth (PD), the width of the keratinized gingiva (WKG), gingival scars (GS), bone loss (BL), and apical root resorption (ARR) were recorded after the removal of the fixed appliance. A two-sample t-test was used for independent samples for parametric variables.
A total of 24 patients with unilateral maxillary canine impaction were successfully treated. The outcomes of GI, WKG, GS, BL, and ARR did not indicate statistical significance between the experimental group and the control group.
The preservation of DF promotes soft tissue management in combined surgical and orthodontic treatment of labially impacted maxillary canine to achieve better periodontal status. Trial Registration Chinese Clinical Trial Registry ChiCTR2000029091, 2020-01-12.
摘要:
本研究旨在报告一项技术上改进的手术方法,以治疗受影响的上颌犬齿的手术暴露。阐述软组织的管理,以达到更好的美学效果,和治疗后的牙周健康。
在这项研究中选择了使用单侧唇阻生上颌犬进行正畸治疗的患者。将受影响的牙齿分配到实验组,将对侧未受影响的犬科动物分配到对照组。受影响的犬科动物通过手术暴露,解剖的牙囊(DF)缝合到牙冠周围的肌肉和粘膜上。牙龈指数(GI),探测深度(PD),角化牙龈的宽度(WKG),牙龈疤痕(GS),骨丢失(BL),去除固定器具后记录根尖吸收(ARR)。参数变量的独立样本采用双样本t检验。
共成功治疗了24例单侧上颌尖牙嵌塞患者。GI的结果,WKG,GS,BL,ARR在实验组和对照组之间没有统计学意义。
保留DF可促进手术和正畸联合治疗上颌尖牙的软组织管理,以获得更好的牙周状态。试验注册中国临床试验注册中心ChiCTR2000029091,2020-01-12。
