Abstract

Aims: The aims of the study are to evaluate the degree of improvement in labiolingual or buccolingual inclination of the teeth after treatment of class II division 1 malocclusion using Roth appliance and to compare the teeth inclination after treatment with that of normal occlusion samples to show if Roth appliance can give a reasonable result with straight arch wire technique. Materials and Methods: A twenty five patients (15–25 years age) with Class II division 1 malocclusion were treated with Roth 22" bracket system after extraction of upper first and lower second premolars to correct molars and canine relation, then the teeth inclination were compared among the four groups on the study casts that were taken before treatment, after treatment, after 1 year retention, and with the control group (25 dental casts of normal Class I occlusion) using special gauge. Results: Significant differences were seen among the four groups in the most of the teeth with the exception of the first molars and upper first premolars with the highest possible value in the(before treatment group). Conclusions: A considerable dispersion around the mean torque measurements was seen in the four groups , more lingual inclination was noticed in distally situated teeth. The preadjusted brackets help in decreasing the labial inclination of the treated teeth in Class II malocclusion making their inclination nearly to control group

Abstract

The purpose of this study was to investigate soft tissueadaptability to hard tissue; in other words, to evaluate the relationbetween the inclination of upper and lower anterior teethwith the upper and lower lips, and how this relation affectthe soft tissue profile in Class II division 1 malocclusion subjectfor both genders (males and females).The sample of this study comprised lateral cephalogramsfrom 40 Class II division 1 malocclusion subjects (20 malesand 20 females) aged 18–25 years. Two dental [upper and lowerincisor inclination {the angle formed between the longaxis of the upper central incisor (U1) and the palatal plane(PP) and the angle formed between the long axis of the lowercentral incisor (L1) and the mandibular plane (MP)}] and threesoft tissue [nasolabial (nla), labiomental (lma) and soft tissuefacial convexity (n–sn–pog)] angular measurements wereanalyzed. The results showed no significant difference betweenmales and females concerning the proclination of upperanterior teeth and the prominency of upper lip, while the femalesexhibited more proclined lower anterior teeth and moreprotrusive lower lip than males. The males tend to have moreconvex facial profile than females
