Severe Anterior Open Bite during Mixed Dentition Treated with Palatal Spurs

Abstract

Deleterious oral habits, such as non-nutritive sucking or tongue thrusting, if not intercepted at an early stage can cause complex malocclusions. This manuscript describes a clinical case report of a successful interception of a severe anterior dental open bite caused by thumb sucking and tongue thrusting habits. The case involved a six-year-old female patient treated with the use of palatal spurs and maxillary removable crib followed by monitoring the development of dental occlusion. At the end of the interceptive phase acceptable results were achieved, showing the efficacy of the treatment undertaken as well the importance of an early intervention to remove harmful oral habits.

Tratamento precoce da mordida aberta: O que é importante saber?

“…(Canuto et al, 2016;Dias et al, 2019). Por sua vez, Nascimento et al, 2016 demonstrou uma associação entre a utilização de esporões linguais junto a um arco palatino fixo, com o objetivo de realizar uma expansão maxilar para complementar o tratamento e proporcionar um maior aumento da sobremordida em casos mais graves, demonstrando que, a depender do caso, associações são feitas para restabelecer a erupção fisiológica dos incisivos.…”

Importance of orthodontic intervention of the Class III malocclusion in mixed dentition

“…In this Class III clinical case, the interceptive approaches to deleterious oral habits together with the early orthopedic treatment of malocclusion, were determining factors for the treatment outcome. [11][12][13][14][15][16][17][18][19][20][21] Some malocclusions, such as crossbites, do not correct themselves and tend to worsen during the child's growth and development. Therefore, they should be treated as soon as they are diagnosed.…”

“…The indication of lingual spurs is presented in the literature as a valid therapeutic modality to eliminate the habit of interposing and reeducating the tongue posture, contributing to the correction of the anterior open bite. 11,15,[26][27][28][29][30] For this reason, immediately after the disjunction of the maxilla, the lingual arch with welded spurs was installed. So that, without the interference of the tongue, the correction of the anterior open bite occurred simultaneously with the effects of the treatment with the facemask that redirected the maxillary growth forward and down.…”

Effectiveness of Tongue Crib Combination Treating Severe Skeletal Angle Class III Malocclusion in Mixed Dentition

“…The etiology of skeletal class III malocclusion involves two factors: heredity and environment, the later included unfavorable growth, digital habits, and tongue habits. Most dentists know the tongue crib appliance is effective in modifying tongue behavior, 16 especially for open bite over several years. It has been described 17 to work as an obstacle in non-nutritive sucking and maintaining the tongue in a more backward position, so prevent tongue thrust.…”
