Abstract
Introduction: In daily practice, it is very common to observe gingival recessions, either single or multiple. Not all of them are discomforting to the patient. In some patients, these recessions can cause various problems such as dentin hypersensitivity, root caries, non-carious cervical lesions, and dental aesthetic degradation. In cases where a surgical procedure is indicated, it is important to evaluate the multiple techniques that can be carried out. Objective: To present the results obtained with the tunnel technique and grafting of connective tissue in Type 1 gingival recessions. Case presentation: According to the periodontal check-up, Type 1 gingival recessions were observed in some teeth in the first and second quadrants; for this reason, the patient presented dental hypersensitivity. Therefore, it was decided to perform root coverage and the technique of choice was tunneling combined with subepithelial connective tissue graft, to obtain a good amount of inserted gingiva and to present ample papillae. This technique is considered a predictable procedure for single and multiple recession defects. Surgery was performed separately, in the first and second quadrant. For both surgeries the donor site was the palatal area. Satisfactory results were obtained, achieving 90% root coverage and a considerable decrease in hypersensitivity. Conclusions: Determining the correct surgical technique is essential to obtain good clinical results, and this tunneling technique proved to be effective for root coverage of Type 1 gingival recessions and to achieve good aesthetic results, considering that it is a predictable technique, especially when there are wide interdental papillae. This technique allows a good blood supply to the connective tissue graft and can be successfully performed in multiple gingival recessions.
