The maxillary and mandibular dental arch forms in different classes of malocclusion in a group of patients from the western part of Romania
Journal Title: Medicine in Evolution - Year 2017, Vol 0, Issue 4
Abstract
Aim: The objective of this study was to determine the shape of the maxillary and mandibular dental arches in Angle Class I, II, and III malocclusions in a group of patients in the western part of Romania. The study was descriptive, non-experimental and transversal. Material and methods: A total of 75 patients with ages between 12 and 39 years were clinically examined over a period of 3 years and divided into 3 groups (25 patients in each group) according to Angle’s classification of malocclusion (Class I, II and III). Exclusion criteria: missing teeth (with the exception of third molar), removable partial denture prostheses, extensive prosthetic restorations, orthognathic surgery and those who refused to participate. The shape of the dental arches was determined on study models using orthodontic archwires overlaid on the occlusal surfaces of the teeth, following the arch perimeter. The archwires were chosen according to the OrthoForm™ (3M Unitek, USA) archwire templates. The results were related to the type of malocclusion. Results: In all of the three groups, the dominant shape of the maxillary and mandibular arches was the tapered shape, followed by the ovoid and the square shape. Conclusions: Dental arch shape is a very important factor that must be taken into account in orthodontic treatment planning, because it plays an important role in maintaining the stability of the treatment results.
