ABSTRACT
(1) Background: This study compared the clinical and esthetic results of the double lateral sliding bridge flap (DLSBF) and the laterally closed tunnel (LCT) techniques, with a subepithelial connective tissue graft (SCTG), for the treatment of single Miller class II-III recessions in the mandibular anterior teeth. (2) Methods: This pseudorandomized clinical trial evaluated 14 patients, 7 of whom were part of the DLSBF + SCTG group, with an average follow-up of 58.7 ± 24.0 months, and 7 of whom were in the LCT + SCTG group, with an average follow-up of 16.7 ± 3.3 months. Clinical and esthetic evaluations of the following parameters were performed and the results for the two groups were compared: gingival recession depth, probing depth, keratinized tissue width, gingival thickness, percentage of root coverage and root coverage esthetic score. (3) Results: After the follow-up period, each technique provided evidence of a reduction in recession depth and clinical attachment level, as well as increased keratinized tissue width and gingival thickness, with statistically significant differences (p < 0.05). The analysis showed that gingival recession depth decreased less in the DLSBF group (4.3 ± 1.2 mm to 0.6 ± 1.1 mm) than it did in the LCT group (4.9 ± 1.1 mm to 0.1 ± 0.4 mm), but no significant difference was found between the two groups. Similarly, a greater reduction in the clinical attachment level parameter was observed in the LCT group, while a greater increase in gingival thickness was observed in the DLSBF group. The presence of scars was the only parameter for which statistically significant differences (p < 0.05) between the two study groups were found. (4) Conclusions: Within the limitations of the study, it indicates that the LCT + SCTG technique may be considered an optimal technique in terms of reducing gingival recession depth, complete root coverage and esthetic results for the treatment of single gingival recessions in the mandibular anterior teeth.
ABSTRACT
INTRODUCCIÓN: La dehiscencia es una pérdida de la cortical que deja expuesta parte de la raíz al medio oral. Se considera como un factor predisponente de las recesiones gingivales y, por tanto, de una alteración estética. El objetivo principal fue estudiar la relación entre la presencia o ausencia de la tabla ósea vestibular en implantes anteriores y el resultado estético valorado mediante el índice Pink Esthetic Score (PES). Los objetivos secundarios fueron analizar la opinión del paciente comparándolo además con lo valores de PES hallados por el evaluador principal. MATERIAL Y MÉTODO: Se llevó a cabo un estudio analítico, longitudinal, retrospectivo, de cohortes en un grupo de 31 pacientes quienes llevaban implantes antero-superiores con un mínimo de 3 años de carga protésica. Se realizó un TAC para valorar la presencia/ausencia de tabla ósea junto con una exploración para evaluar el PES. RESULTADOS: El índice PES fue significativamente más elevado (10,4 ± 2,3) en presencia de tabla ósea. La valoración del paciente tuvo una nota media global de 8,2 ± 1,6. No se halló correlación entre la opinión del paciente y la del evaluador. CONCLUSIONES: La ausencia de tabla ósea vestibular en implantes anteriores conlleva alteraciones estéticas de los tejidos peri-implantarios
INTRODUCTION: Dehiscence is the loss of the bone wall that leaves part of the root exposed to the oral cavity. It can be a predisposing factor of gingival recessions and therefore it is considered an aesthetic alteration. OBJECTIVES: To analyze the relationship between the presence or absence of the buccal bone table in anterior implants and the esthetic result valued using the PES index. Secondary objectives were to analyse the patient's opinion by comparing it with the PES values found by the evaluator. MATERIAL AND METHOD: An analytical, longitudinal, retrospective cohort study was performed in a group of 31 patients who had antero-superiors implants with a minimum of 3 years of crown-loading. CBCT was performed to evaluate the presence /absence of a bone table with an intraoral exploration to evaluate the PES. RESULTS: The PES index was significantly higher (10.4 ± 2.3) in presence of bone table. The patient's assessment had an overall mean score of 8.2 ± 1.6. No correlation was found between the patient's opinion and the evaluator. CONCLUSION: The absence of buccal bone table lead to aesthetic alterations of the peri-implant tissues
