摘　　要：目的:通过数码微笑设计(digital smile design,DSD)来协助上前牙不良修复相关的牙周-修复联合治疗,提高上前牙区美学牙冠延长术后功能和美学恢复的可预测性。方法:12例患者(74颗患牙)于完善牙体、牙周治疗1个月后,通过微笑数字化设计辅助行前牙区美学牙冠延长手术,术后6个月行全瓷冠修复。结果:与基线相比,术前PD和BOP均有显著改善(*P<0.01);与术前相比,术后各随访节点的PD和BOP值均有显著改善(#P<0.01);与术前相比,除术后1个月以外,随访各时间节点PI数值均有显著改善(#P<0.01);修复后6个月及1年后所有修复体颈缘适合性均良好。大部分患者对最终牙龈缘位置协调性,微笑效果以及诊疗过程较为满意。结论:DSD辅助牙周-修复联合治疗不仅为患者维护了健康,更是实现了较好的美学效果,获得了较高的满意度,具有较高的临床应用价值。Objective:To assist the periodontal-restorative combined treatment of upper anterior teeth through digital smile design(DSD).Methods:Twelve patients(74 teeth)underwent esthetic crown lengthening surgery in the upper anterior tooth area with the aid of DSD after perfecting their teeth and periodontal treatment for one month.All-ceramic crown restoration was performed six months after the operation.Results:Postoperative PD and BOP values were statistically different(*P<0.01).Compared with preoperatively,except for 1 month after operation,the PI values at all nodes in the follow-up were significantly improved(#P<0.01).Six months and 1 year after the repair,the neck margins of all restorations were suitable,and there was no obvious gingival hyperplasia or recession.Most patients were satisfied with the final coordination of the gingival margin,the smiling effect,the diagnosis,and treatment process.Conclusion:DSD-assisted periodontal-restorative combined therapy not only maintains the health of patients,but also achieves better aesthetic effects,obtains high satisfaction,and has high clinical application value.
