Chris' Top 11 Cases: 1. Nonsurgical Treatment of Anterior Open Bite Malocclusion

Abstract

This case report describes the nonsurgical treatment of a 31-years-old female presenting with a chief complaint of anterior open bite malocclusion. A clinical exam revealed that there were spaces between her lower anterior teeth. Orthodontics was indicated to align and level the maxillary dentition and close the mandibular spaces. Anterior early light short elastic (2oz) was used to solve the open bite problem. Miniscrews in the infrazygomatic crests was applied to retract the upper and lower dentition and intrude the upper posterior segment. It improved her lip profile and reduced the mandibular angle. Class III elastics were used to correct the negative overjet and continuous intermaxillary elastics were prescribed to settle the final occlusion. A marked improvement in anterior open bite correction and occlusal function was achieved.

Key words:
Anterior open bite malocclusion, early light short elastics, Angle Class I molar relationship, mandibular midline shifted, Damon self-ligating brackets, OrthoBoneScrew, extra-alveolar miniscrews, infrazygomatic crests (IZC), Class III elastics, negative overjet, continuous intermaxillary elastics.
