Abstract
Objective
To evaluate root coverage (RC) in deep single antero‐mandibular RT2 and RT3 gingival recessions (GR) and to investigate the influence of several factors in RC.
Materials and Methods
Fifteen single antero‐mandibular GR with a minimum depth of 3 mm were consecutively treated with a new one‐stage technique (laterally positioned flap with a tunnel access and a connective tissue graft). At baseline and at 12‐month follow‐up, the percentage of mean root coverage (%MRC), the recession reduction (RecRed), complete root coverage (CRC) and the gain of keratinized tissue width (KTW) were assessed. Descriptive, intergroup comparative and correlation analyses were performed.
Results
At 12 months, a %MRC of 77.29 ± 21.48% with a mean RecRed of 4.10 ± 1.51 mm was achieved. The %MRC was 84.71 ± 21.08% in RT2, and 62.43 ± 14.17% in RT3. The mean gain of KTW was 2.10 ± 0.89 mm, with a mean gain of 2.0 ± 1.03 mm for RT2 and 2.3 ± 0.57 mm for RT3. CRC was observed in six cases, all of them being RT2. A positive association was found between the %MRC and the initial position of the tooth and of both papillae.
Conclusions
This technique might be a valuable approach for the treatment of deep single antero‐mandibular RT2 and RT3 recessions, even in malpositioned teeth.
Clinical Significance
A combination of different surgical techniques could provide greater vascularization to the CTG especially in malpositioned teeth in sextant V with a large avascular area to be covered.
