Análise das dimensões anatômicas faciais, periodontais e dentais da erupção passiva alterada tipo 1B: relato de caso com avaliação fotográfica, clínica e tomográfica

Abstract

The evaluation of the facial anatomy can provide important information in the process of diagnosing and defining the treatment plan for patients with Altered Passive Eruption (APE). The objective of this study was to report the clinical case of a patient with APE in which the facial, periodontal and dental anatomical dimensions were analyzed through photographic, clinical and tomographic evaluation. A 30-year-old female patient sought care complaining of excessive gingival display when smiling. In facial analysis, it was found that the upper and middle thirds were well distributed, but the lower third was enlarged. The length of the upper lip at rest was considered medium (21.4 mm), the interlabial space at rest was increased (3.8 mm), the discrepancy between the length of the lip at rest and smile was also increased (9.8 mm). In the periodontal analysis of teeth 13 to 23, it was found that the rates of plaque, gingival bleeding, and bleeding on probing were below 10%; the probing depth ranged from 2 to 3 mm, the range of keratinized gingiva was wide, and the gingival and periodontal phenotype were classified as thick. In the dental analysis, it was observed that the clinical crowns were short (8 to 10 mm), and the distance from the cemento-enamel junction to the bone crest was reduced (1.15 to 1.64 mm). In the present case of Altered Passive Eruption type 1B, elongation of the lower third of the face, gummy smile, lip hyperactivity were also diagnosed.
