美学区单牙即刻种植即刻诱导牙龈成形的临床观察

摘要/Abstract

摘要： 目的观察美学区单牙即刻种植即刻采用临时冠进行牙龈诱导成形的临床效果。方法 2012年3月—2014年9月，选择满足适应证的上颌前牙单牙即刻种植修复患者共45例，随机平均分为A、B、C 3组，每组15例。A组术后即刻采用临时冠进行牙龈诱导成形；B组术后延期采用临时冠诱导牙龈成形；C组术后只安装愈合基台过渡，3个月后进行永久冠修复。修复完成后当天、6个月及12个月，以红色美学指数（PES）对种植体周围软组织进行美学评价；同时在永久修复一年后以视觉模拟评分法（VAS）对患者进行美观满意度调查。结果在追踪评估期间内，A、B、C 3组病例永久修复完成当天PES评分分别为（12.17±1.26）、（11.69±1.08）、（8.73±1.02），统计学分析可见A、B两组之间差异不明显(P＞0.05)，A、C和B、C两组差异显著，具有统计学意义(P＜0.05)。另外，一年后随访调查发现A组患者的美观满意度（92.6%）也明显高于B、C组（87.3%、69.6%）。结论美学区单牙即刻种植即刻采用临时冠诱导牙龈成形技术，临床上具有可行性、短期美学效果可靠，患者满意度较高，但需要严格把握适应证。

Abstract: Objective To observe the clinical effect of immediate implant placement and instantly using provisional restorations on inducing gingival formation in the aesthetic area. Methods 45 patients whose single tooth in the maxillary anterior teeth was treated by immediate implant prosthesis were selected from March 2012 to September 2014. They were randomly divided into Group A, B, and C, 15 cases in each. Group A immediately used provisional restoration to induce gingival formation; Group B postponed using provisional restoration to induce gums; Group C installed only healing abutment as a transition, and made permanent crown restoration 3 months later. After completion of repair on the same day, 6th month and 12th months, aesthetic evaluations were made on soft tissue around the implant by the pink esthetic score (PES). A year later, the patient’s aesthetic satisfaction was investigated using visual analogue scale (VAS) method. Results During the period of tracking assessment, PES of group A, B, C on the day permanent repair was finished were(12.17±1.26), (11.69±1.08), (8.73±1.02), respectively. No obvious difference was found between A and B (P＞ 0.05), while significant differences were found between group A and C, and group B and C (P＜0.05). In addition, the patient’s satisfaction of group A (92.6%) was also significantly higher than group B and C (87.3%, 69.6%) during the follow-up a year later. Conclusion Immediate implant placement and instantly inducing gingival formation in aesthetic area is clinically feasible with reliable short-term effect of aesthetics, and high satisfaction from the patients, which also needs strictly fit the indications.
