Modified Coronally Advanced Tunnel Technique With Porcine Dermal Matrix for Recession Treatment: 12-Month Follow-Up
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.
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.
