背景资料：为了验证早期种植体放置的概念，用于美学敏感的前上颌骨，临床试验应该包括客观的美学标准，当评估结果参数。方法：在这项2- 4年的横断面回顾性研究中，根据早期种植体放置的概念（一种新的综合指数），包括粉色美学评分和白色美学评分（PES/WES;最高可能的综合评分为20分），应用于前牙单牙种植体的客观美学效果评估。所有45个上颌前牙单牙种植体在骨整合方面都符合牙科种植体的严格成功标准，包括缺乏植入物周围射线可透性、植入物移动性、化脓和疼痛。平均总PES/WES为14.7 ± 1.18（范围：11 - 18）。平均总PES为7.8 +/- 0.88（范围：6 - 9），证明植入物周围软组织状况总体良好。两个PES变量面部粘膜曲率（1.9 +/- 0.29）和面部粘膜水平（1.8 +/- 0.42）的平均值最高，而组合变量牙根凸度/软组织颜色和纹理（1.2 +/- 0.53）被证明是最难完全满足的。近中乳头的平均评分为1.6 +/- 0.5，远中乳头的平均评分为1.3 +/- 0.5。平均值为6.9 +/- 1.47（范围：4至10）计算为WES.Conclusions：这项研究表明，上颌前牙单齿置换，根据早期种植体放置的概念，是一个成功的和可预测的治疗方式，一般来说，从美学的角度来看，特别是。PES/WES指数用于前牙单牙种植体美学尺寸的客观结果评估的适用性得到了证实。然而，需要前瞻性临床试验来进一步验证和完善该指数。J Periodontol 2009;80：140-151.
Background: To validate the concept of early implant placement for use in the esthetically sensitive anterior maxilla, clinical trials should ideally include objective esthetic criteria when assessing outcome parameters.Methods: In this cross-sectional, retrospective 2- to 4-year study involving 45 patients treated with maxillary anterior single-tooth implants according to the concept of early implant placement, a novel comprehensive index, comprising pink esthetic score and white esthetic score (PES/WES; the highest possible combined score is 20), was applied for the objective esthetic outcome assessment of anterior single-tooth implants.Results: All 45 anterior maxillary single-tooth implants fulfilled strict success criteria for dental implants with regard to osseointegration, including the absence of peri-implant radiolucency, implant mobility, suppuration, and pain. The mean total PES/WES was 14.7 +/- 1.18 (range: 11 to 18). The mean total PES of 7.8 +/- 0.88 (range: 6 to 9) documents favorable overall peri-implant soft tissue conditions. The two PES variables facial mucosa curvature (1.9 +/- 0.29) and facial mucosa level (1.8 +/- 0.42) had the highest mean values, whereas the combination variable root convexity/soft tissue color and texture (1.2 +/- 0.53) proved to be the most difficult to fully satisfy. Mean scores were 1.6 +/- 0.5 for the mesial papilla and 1.3 +/- 0.5 for the distal papilla. A mean value of 6.9 +/- 1.47 (range: 4 to 10) was calculated for WES.Conclusions: This study demonstrated that anterior maxillary single-tooth replacement, according to the concept of early implant placement, is a successful and predictable treatment modality, in general, and from an esthetic point of view, in particular. The suitability of the PES/WES index for the objective outcome assessment of the esthetic dimension of anterior single-tooth implants was confirmed. However, prospective clinical trials are needed to further validate and refine this index. J Periodontol 2009;80:140-151.
