Measuring soft tissue thickness after mucogingival surgery has traditionally been performed by means of a calibrated transgingival probe. The main aim of this study was to apply a non-invasive technique based on digital images formatted as Standard Tessellation Language (STL) files to quantify soft tissue volume after connective tissue grafting.
Ten patients who presented Cairo Class I gingival recession were selected for connective tissue grafting using the tunnel technique. In all patients, the initial position of the gingiva and quantity of keratinized tissue were recorded, and gingival recession was scanned with an intra-oral scanner. Six months after surgery, the same intra-oral parameters were recorded and compared with the initial registers using digital volumetric analysis software.
Complete root coverage was obtained in most patients (90%), mean coverage being of 2.70 mm with a mean increase in volume of 115.49 mm in the treated areas. No pattern was identified that indicated a statistically significant relation between gingival recession and coverage volume in mm .
Digital processing of pre- and post-treatment images makes it possible to measure the volume of tissue gained after tissue graft surgery simply and non-invasively. The technique is an objective and reproducible method for measuring soft tissue thickness.
传统上，通过校准的龈下探针测量龈黏膜手术后的软组织厚度。本研究的主要目的是应用基于格式化为标准细分语言（STL）文件的数字图像的非侵入性技术，以量化结缔组织移植后的软组织体积。
选择10例开罗I类牙龈退缩患者，采用隧道技术进行结缔组织移植。记录所有患者牙龈的初始位置和角化组织量，并用口腔内扫描仪扫描牙龈退缩情况。术后6个月，记录相同的口腔内参数，并使用数字体积分析软件与初始记录进行比较。
大多数患者（90%）实现了完全牙根覆盖，平均覆盖量为2.70毫米，治疗区域的体积平均增加了115.49立方毫米。未发现表明牙龈退缩与覆盖体积（以毫米为单位）之间存在统计学显著关系的模式。
治疗前后图像的数字处理使得简单且非侵入性地测量组织移植手术后获得的组织体积成为可能。该技术是测量软组织厚度的一种客观且可重复的方法。
