Avaliação estética e funcional de pacientes portadores de agenesia de incisivos laterais superiores tratados com implantes ou fechamento de espaços e reanatomizações dentárias

Abstract

The treatmerit of patients with upper lateral incisor agenesis is an interdisciplinary chalienge that requires correct planning in order to establish function and aesthetics of the smile for a long-term. Assess functional and periodontal aspects in patients with unilateral or bilateral upper lateral incisor agenesis treated with either implants or space closure and dental recontouring. The sample was made up of 68 volunteers divided into three groups: FR - space closure and dental recontouring with composite resin (n = 26); AI - placement of implants in area of agenesis (n = 20); and C - control group (n = 22). A modified Helkimo questionnaire and a Research Diagnostic Criteria for Temporomandibular Disorders were used for the assessment of signs and symptoms of temporomandibular joint disorder by a single, previously calibrated evaluator. The periodontal assessment involved the following aspects: plaque index, bleeding upon probing, pocket depth greater than 3 mm, plaque retention factors, gingival recession, abfraction, periodontal biotype and papilla index. was used to determine associations between the qualitative variables and groups. The test and Kruskal-Wallis test were used to determine differences between groups and the papilla index, respectively. The data were analyzed using Fisher' s exact test, Mann-Whitney and Kruskal-WaIIis nonparametric statistical tests (α=.05). The periodontal conditions analyzed did not differ between treatments. None of the groups were associated with signs and symptoms of temporomandibular joint disorder. The two treatment alternatives for patients with lateral incisor agenesis were satisfactory and achieved functional and periodontal results similar to those of the control group.
