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.

Las periodontitis de comienzo precoz han sido consideradas como un grupo de patologías de escaso interés clínico, debido a su baja prevalencia y a la dificultad de un correcto diagnóstico y tratamiento. Existen aspectos diferenciales con respecto al resto de periodontopatías, como son su agresividad, la tendencia familiar y un diagnóstico precoz relativamente sencillo

Orthodontic treatment was provided after guided tissue regeneration of intrabony defects in 2 patients with periodontal disease. The new attachment obtained by guided tissue regeneration remained stable when subjected to orthodontic forces.

The safety and bone-regenerative capacity of a resorbable membrane (Resolut) was evaluated by a nonrandomized prospective clinical study of patients with periodontal defects. Prior to surgical management all patients underwent scaling and root planing and were instructed on oral hygiene. The study included 18 patients (31 periodontal defects) who received surgical treatment by guided tissue regeneration (GTR) using resorbable membranes. The results were evaluated 12 months after surgery in terms of Plaque Index, bleeding index, probing depth, gingival recession, clinical attachment level, and dental mobility. The results obtained show that the use of resorbable membranes in GTR causes few complications. The mean gain in clinical attachment level (4.06 +/- 1.91 mm), with an attachment level gain of more than 3 mm in 81.2% of the defects, suggests the presence of "new attachment." This difference was clinically and statistically significant (t = 11.03, P = 0). The multivariate regression study showed that 60% of the observed variability (F = 11.48, P < 0.001) in clinical attachment level gain was accounted for by the variable's initial probing depth, the Plaque Index of the tooth subjected to GTR, and the infrabony component of the defect.

The clinical condition of a patient with chronic adult-type periodontal disease, as well as gingival recession reaching the tooth apex on a mandibular lateral incisor, is discussed. Because the use of conventional techniques would have resulted in tooth loss, the guided tissue regeneration procedure was applied, with successful results.

A case is described in which delayed implants were inserted after the creation of a suitable volume of maxillary crest bone. The procedure used osseointegrated implants, expanded polytetrafluoroethylene membranes, and demineralized bone.
