To assess the horizontal mucosal thickness (hMT) at healthy and diseased implant sites and correlate these measurements with respective probing depths (PD).
In 60 patients, hMT was assessed at the buccal aspect of healthy (n = 36) and diseased (peri-implant mucositis: n = 26; peri-implantitis: n = 167) implant sites using a validated ultrasonic A-scanner (Pirop Ultrasonic Biometer A- Scan, Echo-Son, Krancowa, Poland) equipped with a specially designed tissue probe. The corresponding PD values were measured at the mid-buccal aspects.
Median hMT (1.10 mm) at healthy implant sites was significantly lower when compared with diseased sites (1.68 mm; 1.61 mm) (P < 0.001, respectively). These values did not markedly differ by implant location (i.e., upper/lower jaws) or position (i.e., anterior/posterior sites). The regression model failed to reveal a significant linear association between hMT and PD values at healthy and diseased implant sites.
This study has pointed to a significant increase of hMT values at diseased implant sites.
评估健康和患病种植体部位的水平黏膜厚度（hMT），并将这些测量值与相应的探诊深度（PD）相关联。
在 60 名患者中，使用经过验证的超声 A 扫描仪（Pirop Ultrasonic Biometer A-Scan，Echo-Son，Krancowa，波兰），在健康种植体部位（n=36）和患病种植体部位（种植体周围黏膜炎：n=26；种植体周围炎：n=167）的颊侧评估 hMT，该扫描仪配备了专门设计的组织探头。相应的 PD 值在颊侧中部测量。
与患病部位（1.68mm；1.61mm）相比，健康种植体部位的 hMT 中位数（1.10mm）显著降低（P<0.001，分别）。这些值在种植体位置（即上下颌）或位置（即前/后部位）上没有明显差异。回归模型未能揭示健康和患病种植体部位 hMT 值与 PD 值之间存在显著线性关联。
本研究表明，患病种植体部位的 hMT 值显著增加。
