ABSTRACT Cranio-mandibular dysfunction therapy of a moderate Angle Class III malocclusion with retroclined incisors with anterior crossbite and pronounced crowding was based not on extraction of the first premolars but on protrusion of the incisors and the extraction of one lower incisor.Im Rahmen einer kraniomandibulren Dysfunktionstherapie wurde eine moderate Angle-Klasse III mit Steilstand der Frontzhne und frontalem Kreuzbi sowie groem Platzmangel nicht durch Extraktion der ersten Prmolaren, sondern durch Protrusion der Schneidezhne und Extraktion eines unteren Schneidezahnes behandelt.

    ABSTRACT: Extracting a mandibular incisor has been stigmatized as an expedient that may adversely affect the occlusion. However, when properly used, the extraction is only one aspect of the total correction of the malocclusion. Failure to observe this will fulfill the negative predictions. Articulating six maxillary with five mandibular anterior teeth necessitates a visualization of the posttreatment occlusion, and therefore specific criteria for case selection are essential. Treatment trends oscillate between nonextraction and four premolar extractions, with perhaps insufficient attention currently given to alternatives. This middle of the road approach is indicated in carefully selected cases, especially where space requirements and facial esthetics do not call for greater dental movements.

    ABSTRACT: A single mandibular central incisor was removed to treat a Class I malocclusion with crowding and a midline discrepancy. This case report was submitted under category number 10 (optional) and it was believed that the results illustrated the Board objectives of (1) facial harmony, soft tissue balance, and proper proportion, (2) maximum health of the teeth, the supporting tissues and adjacent structures, (3) maximum esthetics, (4) optimal functional relationships, (5) treatment in harmony with the patient's facial growth, and (6) stability. Beginning, completion, and 2-year retention records are included. The text follows the guidelines established by the Board for content and length included in "Specific Instructions for Candidates." [This case report was presented to the American Board of Orthodontics in partial fulfillment of the requirements for the certification process conducted by the Board.]

    ABSTRACT: The extraction of a lower incisor constitutes a therapeutic alternative limited to certain occlusal situations, i.e. supernumerary incisors, tooth size anomalies (peg-shaped upper laterals), ectopic eruption and anterior crossbites. The effect of the extraction of a single incisor on the out of retention alignment of lower anterior teeth was studied in 26 treated cases. Initial (T1), final (T2) and 5-8 years out of retention (T3) dental casts were measured. Mean crowding at the start of treatment (T1 = 3.86 mm) relapsed out of retention (T3 = 1.49 mm), with a net mean improvement of 2.37 mm. Little's irregularity index at the start of treatment (T1 = 6.44) relapsed out of retention (T3 = 2.53), with a net mean improvement of T1-T3 = 3.91. Alignment stability seems to be better than that achieved in cases subjected to premolar extraction.
