To evaluate and compare the growth of gingiva around dental implants following the use of collagen matrices and connective tissue grafts (CTG).
The study included 80 study participants, who were divided into four groups based on the type of material used to enhance gingival thickness. Two groups utilized collagen matrices, Fibro-Gide and FibroMatrix as materials, while the other two groups utilized CTG obtained from the hard palate or tubercle area of the maxilla as controls. Measurements of gum tissue thickness were obtained before surgery and three- and six-months following surgery using three different methods: mucosa piercing with a spreader and ruler, digital impression, and comparison of cone-beam computed tomography (CBCT) scans and digital impressions.
At six-months examination after the use of grafts from the palate and tubercle, there was a significantly greater increase in gum tissue thickness compared to the use of collagen matrices. The increase was 1.6±0.3 mm and 1.7±0.6 mm for palatal and tubercle grafts, correspondingly, compared to 1.3±0.4 mm for Fibro-Gide and 0.9±0.5 mm for FibroMatrix.
To increase the thickness of soft tissue it is recommended to use CTG from the tubercle or palate. If there is a lack of available donor areas, collagen matrices may be used as a substitute.
评估和比较使用胶原基质和结缔组织移植（CTG）后牙种植体周围牙龈的生长情况。
该研究纳入80名研究参与者，根据用于增加牙龈厚度的材料类型将其分为四组。两组使用胶原基质，即Fibro - Gide和FibroMatrix作为材料，而另外两组使用从硬腭或上颌结节区域获取的CTG作为对照。在手术前以及手术后三个月和六个月，使用三种不同方法测量牙龈组织厚度：用撑开器和尺子穿刺黏膜、数字印模以及比较锥形束计算机断层扫描（CBCT）图像和数字印模。
在使用腭部和结节处的移植物六个月后进行检查时，与使用胶原基质相比，牙龈组织厚度的增加显著更大。腭部和结节处移植物的增加量分别为1.6±0.3毫米和1.7±0.6毫米，而Fibro - Gide为1.3±0.4毫米，FibroMatrix为0.9±0.5毫米。
为增加软组织厚度，建议使用来自结节或腭部的CTG。如果缺乏可用的供体区域，胶原基质可作为替代品使用。
