Abstract
Deep bite malocclusion impacts function of the stomatognathic system, patients’ quality of life and self-stem by compromising oral and facial esthetics. The malocclusion can involve teeth and facial skeleton, for such is one of the most challenging malocclusion treatments. The aim of this investigation is to check the clinical belief that Planas’ Equiplan is efficient to treat deep bite malocclusion. Dental overbite was measured in 21 patients submitting to Jaw Functional Orthopedics treatment at post-graduation course. The inclusion criteria were a vertical trespass of the incisal border of the upper incisors covering the vestibular face of the lower incisors more than 3 mm, treatment cooperation and a consent form signed by the patients, or their legal tutor, allowing the use of the data obtained for research and didactic purposes. The initial measurement (T0) and 15 months treatment (T1) was collected to study overbite behavior during treatment with Planas’ Equiplan. The mean overbite of the sample at T0 was 5,02 ± 1,311 mm, at T1 the mean overbite was 2,38 ± 1,026 mm. The difference T1-T0 is –2,65 ± 1,462 mm (p< 0,01). The data presented here supports the efficacy of the use of Planas’ Equiplan in the treatment of Deep bite Malocclusion.
Highlights
Deep overbite has been considered as one of the most common malocclusion problems that are difficult to be treated and retained
In a study among Mongolian adolescents Araki et al [6] found that deep bite and increased overjet malocclusions affect oral health-related quality of life and deep bite malocclusion was significantly associated with oral symptoms and functional limitations
The sample was composed by patients treated in Jaw Functional Orthopedics (JFO) post-graduation in the Brazilian Association of Dentistry – Muriaé – MG. 257 patients, of both sexes were treated, 69 (27%) patients presented deep bite malocclusion
Summary
Deep overbite has been considered as one of the most common malocclusion problems that are difficult to be treated and retained. Correction of the deep bite is often a main objective of the orthodontic treatment because of its potentially detrimental effects on periodontal health, temporomandibular joint function, as well as esthetics [1, 2]. Prevalence of deep overbite was found to be 21 % to 26 % in the normal population [3], and about 75 % in orthodontic patients [4]. Deep bite is a malocclusion that can have dental or skeletal component. Among the clinical characteristics of deep bite are short anterior lower face height, reduced mandibular angle (skeletal etiology), supra occlusion of incisors/infra occlusion of posterior teeth and deeper curve of Spee (dental etiology) [5]. Biomechanical alterations in the Stomatognathic System in individuals with deep bite malocclusion are reported [2, 7,8,9]
