Total edentulousness leads to soft tissue changes causing esthetic problems. Being aware of the significant effects of different treatment approaches on facial soft tissue can help to obtain more satisfying esthetic results.
The current study's objective was to evaluate three-dimensional facial soft tissue changes in edentulous patients rehabilitated with a complete denture (CD) and implant-supported fixed partial denture (FPD).
Fourteen edentulous patients, mean age of 47.6 years (42-63), were assessed before prosthetic treatments (T0), after CD (T1), and after FPD (T2). 3dMDface System (3dMD LLC) obtained the images and transferred them to 3dMD Vultus software (3dMD Vultus software Version 2.3.0.2). Nine linear, five angular, and one topographical measurement were performed for facial soft tissue analysis. For statistical analysis of facial soft tissue, ANOVA was used with a level of significance set at 5% (p <.05).
Significant differences were observed in lower lip height (Sto-Sl) and nasolabial angle (Prn Sn Ls) with CD. There is no significant difference with the implant-supported fixed partial dentures in these measurements when compared with pretreatment. Significant differences were observed in the lower lip angle (Chr Li Chl) with the implant-supported fixed partial dentures. There is no significant difference with CD in this measurement when compared with pretreatment. According to the paired comparisons, a significant difference was observed in philtrum height (Ls-Sn) between the treatment approaches.
CD and implant-supported fixed partial dentures, both treatment approaches, cause facial soft tissue changes, which may help to improve the facial esthetic. The effects of these treatment methods on facial soft tissues are not significantly different, except the philtrum height.
全口无牙导致软组织发生变化，引发美观问题。了解不同治疗方法对面部软组织的显著影响有助于获得更满意的美观效果。
本研究旨在评估全口义齿（CD）和种植体支持的固定局部义齿（FPD）修复的无牙患者的三维面部软组织变化。
评估了 14 名无牙患者（平均年龄 47.6 岁，42-63 岁）的情况，在修复治疗前（T0）、全口义齿修复后（T1）和种植体支持的固定局部义齿修复后（T2）。使用 3dMDface System（3dMD LLC）获取图像，并将其传输到 3dMD Vultus 软件（3dMD Vultus software Version 2.3.0.2）。对面部软组织分析进行了 9 项线性、5 项角度和 1 项地形测量。为了对面部软组织进行统计分析，使用了方差分析，显著性水平设置为 5%（p<.05）。
全口义齿修复后，下唇高度（Sto-Sl）和鼻唇角（Prn Sn Ls）有显著差异。与治疗前相比，种植体支持的固定局部义齿在这些测量中没有显著差异。种植体支持的固定局部义齿在下唇角（Chr Li Chl）方面有显著差异。与全口义齿相比，在这个测量中没有显著差异。根据配对比较，两种治疗方法在人中高度（Ls-Sn）上有显著差异。
全口义齿和种植体支持的固定局部义齿都会引起面部软组织的变化，这可能有助于改善面部美观。这些治疗方法对面部软组织的影响没有显著差异，除了人中高度。
