The aim of the present study was to describe and compare the features of the buccal peri-implant mucosa to natural gingiva in the aesthetic area.
Forty-nine periodontally healthy patients were included in this cross-sectional study. Mucosal and gingival dimensions at the mid-facial aspect were evaluated clinically and radiographically. Color assessments were performed using a reflectance spectrophotometer, and patient aesthetic satisfaction was further checked.
Implant sites revealed significant thicker mucosa when compared to tooth sites both at 1.5 (p < 0.001) and 3 mm (p < 0.001) apical to the mucosal margin. Both conventional and digital methods presented a good reliability. The spectrophotometric data revealed a statistically significant color difference between the peri-implant mucosa and the gingiva. However, there was no further significant relation between these color changes and the mucosal thickness.
Peri-implant mucosa revealed a darkish, greenish, and bluish discoloration when compared to the gingiva. More satisfactory patient´s aesthetic evaluation was reported in sites with thicker and comparatively lighter mucosa when compared to the adjacent dentition.
This article focuses on variables affecting color stability and aesthetics around dental implants. These can be assessed to identify the need for peri-implant phenotypic modification.
本研究旨在描述和比较美学区域颊侧种植体周围黏膜与天然牙龈的特征。
本横断面研究纳入了 49 名牙周健康的患者。临床和影像学评估颊侧黏膜和牙龈的近远中向尺寸。使用反射分光光度计进行颜色评估，并进一步检查患者的美学满意度。
与牙位相比，种植体部位在黏膜边缘上方 1.5 和 3 毫米处的黏膜明显更厚（p<0.001）。传统和数字方法均具有良好的可靠性。分光光度数据显示种植体周围黏膜与牙龈之间存在统计学上显著的颜色差异。然而，黏膜厚度与这些颜色变化之间没有进一步的显著关系。
与牙龈相比，种植体周围黏膜呈现出暗绿色和蓝色变色。与相邻牙齿相比，黏膜较厚且相对较浅的部位报告了更令人满意的患者美学评估。
本文重点关注影响种植体周围颜色稳定性和美学的变量。可以评估这些变量以确定是否需要对种植体周围表型进行修饰。
