Abstract

Objectives

To assess the efficacy of the modified coronally advanced tunnel technique (MCAT) with a porcine dermal matrix (PDM) after a 12-month follow-up. There are no other Clinical trials evaluating a PDM over the period of 12 months.

Material and Methods

Patients with recession type (RT) 1 and RT 2 gingival recessions were treated with the MCAT and a novel PDM. Plaster casts (preoperative and 12 months postoperative) were scanned using a 3Shape Lab Scanner E3. The resulting STL files were imported and superimposed in the open-source software GOM Inspect for analysis. Measurements included recession depth, mean root and total root coverage (mRC and cRC), mean recession reduction (mRR), and gingival thickness. Statistical analysis was performed using mixed linear models.

Results

A total of 77 teeth (19 patients) were included in the study. Healing was uneventful in all patients. The mean preoperative recession depth was 1.26 mm ± 0.86 mm. mRC was 69.47% ± 61.90%, cRC was 29.79%, mRR was 0.87 ± 0.83 mm, and gingival thickness gain was 0.23 ± 0.24 mm, with comparable results for RT 1 and RT 2. Neither tooth type nor jaw type had any effect on root coverage.

Conclusions

The modified coronally advanced tunnel technique in combination with the analyzed porcine dermal matrix demonstrated stable results for root coverage and gingival thickness after 12 months of follow-up.

改良冠状动脉隧道技术与猪真皮基质治疗衰退：12个月的随访

目的评价改良冠状动脉隧道技术（MCAT）与猪真皮基质（PDM）在12个月的随访后的疗效。目前还没有其他临床试验对PDM进行为期12个月的评估。材料与方法对萎缩型（RT） 1和RT 2牙龈萎缩患者进行MCAT和新型PDM治疗。使用3Shape Lab扫描仪E3扫描石膏模型（术前和术后12个月）。生成的STL文件被导入并叠加在开源软件GOM Inspect中进行分析。测量包括退缩深度、平均根和总根覆盖（mRC和cRC）、平均退缩减少（mRR）和牙龈厚度。采用混合线性模型进行统计分析。结果共纳入患者19例，共77颗牙。所有患者的愈合都很顺利。术前平均退行深度为1.26 mm±0.86 mm。mRC为69.47%±61.90%，cRC为29.79%，mRR为0.87±0.83 mm，牙龈厚度增加0.23±0.24 mm， rt1和rt2结果相当。牙型和颌型对牙根覆盖均无影响。结论改良的冠状推进隧道技术与所分析的猪真皮基质相结合，经过12个月的随访，根覆盖和牙龈厚度稳定。试验注册：Deutsches Register Klinischer studen /German Clinical Trial Register (DRKS)；DRKS00023201。

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.
