摘要
目的探究正畸牵引配合烤瓷美容修复在治疗前牙龈下冠折上的临床应用效果。方法将汉中市中心医院口腔科于2015年5月至2016年9月收治的188例前牙龈下冠折患者作为研究对象,按照患者住院ID编号尾数随机分为观察组97例和对照组91例。对照组患者切除牙龈后进行烤瓷修复;观察组患者选择正畸牵引联合烤瓷修复进行治疗。治疗1年后对比两组患者的治疗效果、咬合功能、红色美学指数(PES)与白色美学指数(WES)以及不良反应发生情况。结果观察组患者的治疗总有效率为97.94%,明显高于对照组的90.11%,差异有统计学意义(P<0.05);观察组患者在治疗1年后牙尖交错位(ICP-HB)习惯咬合状态、最大力紧咬合状态(ICP-MC)时的TA肌电值以及PES、WES指数水平分别为(74.05±4.94) mV、(76.24±5.07) mV、(8.28±1.13)分、(8.24±1.16)分、均明显高于对照组的(69.21±4.11) mV、(71.35±4.23) mV、(7.24±0.97)分、(7.33±0.94)分,差异均有统计学意义(P<0.05);观察组患者对美容修复的总满意度为97.94%,明显高于对照组的90.11%,差异有统计学意义(P<0.05);观察组患者出现牙龈充血、牙周水肿、牙齿疼痛、骨质吸收以及牙冠松动等不良反应发生率分别为5.15%、4.12%、5.15%、2.06%、1.03%,均明显低于对照组的14.29%、15.38%、17.58%、10.99%、6.59%,差异均有统计学意义(P<0.05)。结论在修复治疗前牙龈下冠折上,正畸牵引联合烤瓷美容修复有助于前牙功能和面部美观的恢复,同时也能够较好保存残留的牙根及牙周组织,达到了美观、牢固、舒适的要求,其修复效果优于单纯烤瓷修复,值得在临床上积极推广。
Objective To study the clinical application of orthodontic traction combined with porcelain cosmetic restoration in the treatment of anterior subgingival crown fold. Methods From May 2015 to September 2016, 188 cases of patients with anterior subgingival crown fold who treated in Department of Stomatology of Hanzhong Central Hospital were selected as the research objects. According to the hospitalization ID number, they were randomly divided into the observation group (97 cases) and the control group (91 cases). The control group was treated with porcelain- fused-to-metal (PFM) after gingiva excision. The patients in the observation group were treated with orthodontic traction combined with porcelain repair. The clinical efficacy, occlusal function, pink esthetic score (PES), white esthetic score (WES), and adverse reactions of the two groups were compared after one year. Results The total effective rate of the observation group was 97.94%, which was significantly higher than 90.11% of the control group (P<0.05). After one year, the tibialis anterior (TA) electromyographic (EMG) value of the interlocking position of the cusp (ICP-HB), the occlusal state of the maximum force (ICP-MC), PES, and WES indexes in the observation group were (74.05±4.94) mV, (76.24±5.07) mV, (8.28±1.13), (8.24±1.16), respectively, which were significantly higher than corresponding (69.21±4.11) mV, (71.35±4.23) mV, (7.24±0.97), (7.33±0.94) in the control group (P<0.05). The total satisfaction of the observation group on the cosmetic repair was 97.94%, which was significantly higher than 90.11% of the control group (P<0.05). The incidence of adverse reactions such as gingival congestion, periodontal edema, tooth pain, bone resorption and crown loosening in the observation group were 5.15%, 4.12%, 5.15%, 2.06%, 1.03%, respectively, which were significantly lower than corresponding 14.29%, 15.38%, 17.58%, 10.99%, 6.59% in the control group (P<0.05). Conclusion In the treatment of anterior subgingival crown fold, orthodontic traction combined with porcelain ceramic restoration not only help to restore the function of the anterior teeth and the beauty of the face, but also can preserve the residual root and periodontium. It has achieved beautiful, strong and comfortable requirements with better repair effect than pure porcelain repair, which is worthy of promoting in clinical practice.
