Abstract
ABSTRACTExtraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. However, the fundamental reality that determines the occlusion final position is the control exerted by the orthodontist while closing the extraction spaces. A specific treatment objective may require the posterior teeth to remain in a constant position anteroposteriorly as well as vertically, while the anterior teeth occupy the entire extraction site. Another treatment objective may require the opposite, or any number of intentional alternatives of extraction site closure. The present case report describes a simple controlled segmented mechanic system that permitted definable and predictable force systems to be applied and allowed to predict the treatment outcome with confidence. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) in partial fulfillment of the requirements for Diplomate certification.
Highlights
This patient was a healthy 31-year-old woman with a chief complaint of “protruded teeth affecting my smile”. Her medical history showed no contraindication to orthodontic treatment
TREATMENT PLAN The treatment objectives were to: (1) reduce the excessive protrusion of both dental arches; (2) obtain normal canine and incisal guidance; (3) correct lip incompetence and lip strain on closure; (4) correct the Class II dental relationship; (5) level the curve of Spee; (6) achieve optimal overjet and overbite, and (7) improve the facial balance
The appliances were removed after 24 months of treatment, when a maxillary wraparound and a mandibular bonded premolar-to-premolar fixed retainer were installed on the patient
Summary
Extraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. A specific treatment objective may require the posterior teeth to remain in a constant position anteroposteriorly as well as vertically, while the anterior teeth occupy the entire extraction site. The present case report describes a simple controlled segmented mechanic system that permitted definable and predictable force systems to be applied and allowed to predict the treatment outcome with confidence. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) in partial fulfillment of the requirements for Diplomate certification. Um objetivo específico do tratamento pode exigir que os dentes posteriores permaneçam estáveis em uma posição sagital e vertical, enquanto os dentes anteriores são retraídos e ocupam todo o espaço da extração.
