The application of acellular dermal matrix combined with modified tunnel technique in the treatment of gingival recessions / 实用口腔医学杂志

ABSTRACT

Objective: To observe the clinical efficacy of acellular dermal matrix combined with modified tunnel in the treatment of gingival recessions. Methods: 27 teeth with gingival recessions in 8 patients were treated by the means of acellular dermal matrix and modified tunnel technique and were followed up for 1 year. The clinical parameters of gingival recession depth,recession width,keratinized tissue height,probing depth and clinical attachment level were assessed. Percentage of root coverage(PRC),complete root coverage(CRC) and patient satisfactions were evaluated. Results: 1 years after treatment PRC reached to 76％,19 teeth got complete root coverage. Recession depth and recession width were significantly decreased(P ＜ 0. 05). Keratinized tissue height increased by(1. 25 ± 0. 24) mm. Clinical attachment level increased by(2. 75 ± 0. 59) mm. Conclusion: Acellular dermal matrix allograft combined with modified tunnel technique is effective in the treatment of gingival recessions.
