简要总结
This is a randomized triple-blind clinical trial. This comparative clinical study investigates the efficacy of root coverage using two periodontal techniques: the tunneling technique and the coronal advancement technique. The objective is to evaluate and compare the clinical, esthetic and patient perception outcomes after undergoing each procedure. Participants with specific gingival recessions will be included, and follow-up will be performed to measure root coverage, keratinized tissue gain and other relevant parameters. In addition, a detailed analysis of the morbidity associated with each technique will be performed. This study aims to provide valuable information to guide oral health professionals in choosing the most appropriate technique for the treatment of gingival recessions.
详细描述
Donor area Surgeries were initiated in all participants by removing connective tissue from the mucosa of the palate using the deepithelialized free gingival graft technique.
Receiving area
- TUN + CTG (test group)
Zabalegui et al. detailed the surgical procedure as follows:
The tunnel is created by making a partial-thickness incision in each recession area that will be addressed in the procedure. Special attention is paid to the manipulation of the tissue beyond the mucogingival junction, in order to obtain a tunnel without tension that facilitates the insertion of the graft.
