A study was conducted to investigate the clinical effects of oral digital design on the aesthetic restoration of anterior teeth of cleft lip/palate patients.
Nine adult cleft lip/palate patients who need aesthetic restoration of anterior teeth were recruited. Digital information of patients' dental arches, the surrounding soft tissue and face were captured by digital camera and scanner. The aesthetic analysis and design were conducted using keynote and 3shape software and were demonstrated to the patients. The optimized treatment plan was ensured by communicating with the patients. Digital wax-up models were exported and printed into resin diagnostic models, which were then utilized in the treatment process to guide the doctors and the technicians in tooth preparation and in making the final restorations, respectively. The adhesive procedure was completed after satisfactory try-in. Aesthetics assessment was conducted in accordance with the anterior esthetic evaluation form. The scores of patient's satisfaction were recorded on a questionnaire containing six items of aesthetic index and doctor-patient communication. Patients were interviewed and examined after 1, 3, 6, and 12 months, respectively, and the clinical effects of restorations were evaluated.
All nine patients had satisfactory clinical results. The aesthetic defects of the patients were effectively addressed. All treatments met the requirements of the preoperative digital designs. The patients' scores were all above 90 on the satisfaction scale. At 12 months after the operation, the clinical effects of restorations of all cases achieved A class in each evaluation indicator.
For cleft lip/palate patients with esthetic defect in the anterior teeth, the digital design plays an important role in optimizing the treatment plan and guides the whole treatment process. This design can help clinicians achieve predictable satisfactory aesthetic results.
研究口腔数字化设计在前腭裂患者前牙美学修复中的临床效果。
纳入 9 例需要前牙美学修复的成人前腭裂患者，应用数码摄像机和扫描仪获取患者牙弓、周围软组织及面型的数字化信息，应用 keynote 和 3shape 软件进行美学分析和设计，并与患者沟通，确保优化治疗方案，将优化后的治疗方案导入口腔数字化设计软件中，输出数字蜡型并打印成树脂诊断模型，指导医生进行牙体预备，指导技师进行最终修复体的制作，试戴合适后完成粘结，采用前牙美学评价表进行美学评价。采用包含 6 项美学指标和医患沟通的问卷记录患者满意度评分。患者分别于治疗后 1、3、6、12 个月进行随访，评价修复体的临床效果。
9 例患者均获得满意的临床效果，有效改善了患者的美学缺陷，所有治疗均符合术前数字化设计要求，患者满意度评分均在 90 分以上。术后 12 个月，所有病例的各项评价指标均达到 A 级。
对于前牙美学缺陷的前腭裂患者，数字化设计在优化治疗方案和指导整个治疗过程中发挥着重要作用，有助于临床医生获得可预测的满意美学效果。
