摘要

研究目的这项横断面研究的主要目的是调查修复体设计与种植体周围粘膜尺寸和形态之间的关系。次要目的是研究粘膜尺寸与是否存在粘膜炎之间的关系：47名患者的103颗后牙骨质种植体接受了临床和放射学检查，包括锥形束计算机断层扫描和口内光学扫描。建立了每个种植体和种植体周围粘膜的三维模型。在每个种植体的六个部位测量了粘膜垂直高度（TH）、种植体平台处粘膜水平宽度（TW）、平台冠向 1.5 mm 宽度（TW1.5）以及粘膜萌出角（MEA）、深角（DA）和总轮廓角（TA）：结果：种植体周围粘膜宽度和高度之间存在一致的相关性（β = 0.217，p 结论：种植体周围粘膜宽度和高度之间存在一致的相关性：假体设计会影响种植体周围粘膜的尺寸，较宽的种植体外形角会降低种植体周围粘膜的高度。特别是，较宽的深角与后部粘膜宽度减少有关。种植体周围粘膜高度和宽度的降低与更多的炎症迹象有关：在泰国临床试验注册中心注册：http://www.thaiclinicaltrials.org/show/TCTR20220204002。

Association of Peri-Implant Mucosa Dimensions With Emergence Profile Angles of the Implant Prosthesis

Objectives

The primary aim of this cross-sectional study was to investigate the association between prosthesis design and peri-implant mucosa dimensions and morphology. The secondary aim was to investigate associations between mucosal dimensions and the presence of mucositis.

Materials and Methods

Forty-seven patients with 103 posterior bone level implants underwent clinical and radiographic examination, including cone beam computer tomography and intraoral optical scanning. Three-dimensional models for each implant and peri-implant mucosa were constructed. Vertical mucosa height (TH), horizontal mucosa width at implant platform (TW), and 1.5 mm coronal of the platform (TW1.5), as well as mucosal emergence angle (MEA), deep angle (DA), and total contour angle (TA) were measured at six sites for each implant.

Results

There was a consistent correlation between peri-implant mucosa width and height (β = 0.217, p < 0.001), with the width consistently surpassing height by a factor of 1.4–2.1. All three angles (MEA, DA, TA) were negatively associated with mucosa height (p < 0.001), while DA was negatively associated with mucosa width (TW1.5) (p < 0.001, β = −0.02, 95% CI: −0.03, −0.01). There was a significant negative association between bleeding on probing (BoP) and mucosa width at platform (OR 0.903, 95% CI: 0.818–0.997, p = 0.043) and 1.5 coronal (OR 0.877, 95% CI: 0.778–0.989, p = 0.033). Implants with less than half sites positive for BoP (0–2/6) had significantly higher mucosa height (OR 3.51, 95% CI: 1.72–7.14, p = 0.001).

Conclusions

Prosthesis design can influence the dimensions of the peri-implant mucosa, with wider emergence profile angles associated with reduced peri-implant mucosa height. In particular, a wider deep angle is associated with reduced mucosa width in posterior sites. Reduced peri-implant mucosa height and width are associated with more signs of inflammation.

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
