摘要: 目的

探讨口腔数字化设计技术在唇腭裂患者前牙美学修复中的应用效果。

方法

选择裂隙区需要前牙美学修复的唇腭裂成年患者9例,获取患者口内前牙与周围软组织及面部的美学数字化信息,利用keynote及3shape软件进行美学修复分析设计,与患者沟通优化修复方案,生成3D诊断蜡型并打印树脂实体诊断模型,在口内制作树脂罩面指导医生牙体预备及技师制作最终修复体,患者试戴满意后黏结。在修复完成后结合美学评估表对美学缺陷改善情况进行比较;采用调查问卷的形式让患者对前牙美学参数及医患沟通等6项内容打分做出满意度评价;在修复体戴入后1、3、6和12个月对临床效果进行评价。

结果

9例唇腭裂患者的前牙美学参数均得到有效改善,修复效果均达到术前数字化设计预期;各项满意度均在90分以上。修复后12个月临床效果各项指标均为A。

结论

口腔数字化设计技术应用于唇腭裂患者前牙美学修复,有助于优化治疗方案,指导整个治疗流程,最终达到满意的美学效果。

Abstract: Objective

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.

Methods

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.

Results

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.

Conclusion

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.
