A smile plays an important role in determining a person's initial impression.
This study aims to evaluate the effectiveness of both injection botulinum toxin type A (botox) and surgical lip repositioning in the correction of the gummy smile due to hyperactive upper lip according to the resulting smile and the patients' satisfaction.
The study consisted of 24 patients: 12 received the BTX-A (botulinum toxin type-A) injection and the remaining 12 underwent the surgical procedure (lip repositioning). The patients rated their satisfaction according to their gingival display that was defined as the difference between the lower margin of the upper lip and the superior margin of the right incisor, and patients were followed at 2 weeks, 2 months, and 6 months. Post injection and post-surgery with changes documented by photographs. Both groups answered a questionnaire addressing the overall appearance and they were asked to rate the improvement of their smile according to a 5-point aesthetic scale.
The patients rated the effects of BTX-A as highly favorable if we take into consideration that BTX-A had a temporary effect while the surgical procedure (lip repositioning) had a relapse likelihood of more than 80% because the lip reverted back to its original position with almost complete relapse after 6 months and not to mention the risks affiliated with the surgical procedures.
BTX-A injection exhibits better results than those of surgery and had given safer and more satisfactory results and achieved the required cosmetic patient requirement than lip repositioning.
微笑在决定一个人的第一印象方面起着重要作用。
本研究旨在根据最终的笑容和患者满意度，评估A型肉毒杆菌毒素（保妥适）注射和手术性唇部复位术对因上唇活动过度导致的露龈笑的矫正效果。
该研究包括24名患者：12名接受了A型肉毒杆菌毒素注射，其余12名接受了手术治疗（唇部复位术）。患者根据牙龈暴露程度对满意度进行评分，牙龈暴露程度定义为上唇下缘与右上切牙上缘之间的差异，并在2周、2个月和6个月时对患者进行随访。注射后和手术后通过照片记录变化。两组均回答了一份关于整体外观的问卷，并被要求根据5分美学量表对其笑容改善情况进行评分。
如果考虑到A型肉毒杆菌毒素具有暂时效果，而手术治疗（唇部复位术）复发可能性超过80%，因为6个月后嘴唇几乎完全复发回到原来位置，更不用说手术相关风险，患者对A型肉毒杆菌毒素的效果评价很高。
与唇部复位术相比，A型肉毒杆菌毒素注射显示出更好的效果，提供了更安全、更令人满意的结果，并达到了患者所需的美容要求。
