Dentoalveolar characteristics in subjects with different anteroposterior relationships: a retrospective cross-sectional Cone-Beam Computed Tomography study.

Background: The collum angle, tooth dimensions, root length, and alveolar bone thickness have a significant impact on orthodontic diagnosis and treatment planning. The boundaries of orthodontic tooth movement are determined by alveolar bone thickness and dimensions while the collum angle determines the appropriate positioning of the root relative to the cortical plate. This study aimed to compare the collum angle, crown dimensions, root length, and alveolar bone thickness of the upper and lower incisors, canines, and premolars in subjects with varying anteroposterior relationships.

Comparison of transverse dimensional and incisor changes between wide and narrow orthodontic archwires: a randomized controlled trial.

Objectives: To clinically compare the effects of broader archwires to standard archwires, using conventional brackets in both cases, on the transverse and incisor changes in maxillary and mandibular arches during leveling and alignment.

Materials And Methods: Fifty-two patients presenting with crowding were allocated into two groups; one group received the broad Damon archwires while the other received standard 3M OrthoForm III Ovoid archwires. All participants were treated with conventional brackets using similar archwire sequences (0.

Objectives: To compare between two archwire (AW) sequences in terms of alignment speed and root resorption (RR).

Materials And Methods: Fifty-four patients (14 males, 40 females) requiring orthodontic treatment were randomly allocated into two groups; in group A (mean age 18.3) treatment started with 0.

A comparative study between the effect of reverse curve of Spee archwires and anterior bite turbos in the treatment of deep overbite cases.

Objectives: To compare deep overbite treatment using 0.016 × 0.022 nickel-titanium lower reverse curve of Spee archwire (LRCA) or metal anterior bite turbos (ABTs).

Pain experience during initial alignment with three types of nickel-titanium archwires: a prospective clinical trial.

Objective: To clinically evaluate the pain intensity during the week following initial placement of three different orthodontic aligning archwires.

Materials And Methods: A consecutive sample of 75 patients requiring upper and lower fixed orthodontic appliances were alternately allocated into three different archwires (0.014-inch superelastic NiTi, 0.

A clinical comparison of three aligning archwires in terms of alignment efficiency: A prospective clinical trial.

Objectives: To clinically evaluate the effectiveness of three orthodontic aligning archwires in relation to tooth alignment speed during the initial alignment stage of treatment.

Materials And Methods: A consecutive sample of 74 patients requiring lower only or upper and lower fixed orthodontic appliances were randomly allocated into three different archwires (0.014-inch superelastic nickel-titanium [NiTi], 0.

Maxillary palatal canine impaction displacement in subjects with congenitally missing maxillary lateral incisors.

Introduction: The aims of this research were to study the prevalence of palatally displaced maxillary canines (PDCs) in subjects with congenitally missing maxillary lateral incisor (MxI2) teeth and to assess the dental and occlusal features associated with this displacement in these subjects.

Methods: The material for this study consisted of the pretreatment orthodontic casts of 246 subjects (78 male, 168 female) with missing MxI2 teeth. These were divided into 2 groups: subjects with PDC (displacement group) and subjects with no PDC (nondisplacement group).

Functional occlusal patterns and their relationship to static occlusion.

Objectives: To test the hypothesis that there is no relationship between static occlusion and dynamic occlusion.

Materials And Methods: The relationship between static and dynamic occlusion was investigated in a sample of 94 dental students (39 males and 55 females) with an age range of 21-30 years. Static occlusion was determined by intraoral examination.

Maxillary incisor proclination effect on the position of point A in Class II division 2 malocclusion.

Objective: To test the hypothesis that the magnitude of alteration in the position of point A is not associated with proclination of the upper incisors in Class II division 2 malocclusion.

Materials And Methods: Cephalometric films were taken for 30 Class II division 2 patients (8 males and 22 females; average age, 18.3 years) before and after upper incisor proclination.

Postoperative pain after surgical exposure of palatally impacted canines: closed-eruption versus open-eruption, a prospective randomized study.

Objectives: The aim of this prospective randomized clinical study was to compare the duration of surgery and the patient's perception of pain after closed and open surgical exposure of unilateral palatally impacted maxillary canines.

Study Design: Palatally impacted canines were exposed in 32 subjects. Half of these subjects had closed-eruption exposure, and the other half had open-eruption exposure.

Vertical changes in class II division 1 malocclusion after premolar extractions.

The purpose of this study was to compare changes in the facial vertical dimension in patients with Class II division 1 malocclusion after the extraction of either mandibular first premolars or mandibular second premolars. The records of two groups of patients were used: one group was treated with extraction of mandibular first premolars (age: 13.2 +/- 1.

Prevalence of malocclusion in 13-15 year-old North Jordanian school children.

Objectives: This study was carried out to determine the prevalence of malocclusion in 13-15-year-old North Jordanian schoolchildren.

Methods: One thousand and three children aged 13-15 years (619 females, 384 males) were examined using Björk et al. (1964) registration method.

Self-perception of malocclusion among north Jordanian school children.

This study was undertaken to assess the factors affecting self-perception and the demand for orthodontic treatment among north Jordanian school children. In total, 1404 students randomly selected to represent five geographical areas of northern Jordan were examined. The students were further subgrouped according to gender (858 females, 546 males), age (985 13 year olds, 419 17 year olds) and rural/urban place of residence (212 rural, 1192 urban).

Orthodontic treatment need and demand in 12-14-year-old north Jordanian school children.

This study was undertaken to assess the need and demand for orthodontic treatment among 12-14-year-old north Jordanian school children. In total, 1002 students randomly selected to represent five geographical areas of Irbid were examined. The examinations were carried out twice, first on the pupils in the school premises and then using study models taken from each student.

Changes in mandibular incisor position in Class II Division 1 malocclusion treated with premolar extractions.

The aim of this study was to investigate the magnitude of mandibular incisor retraction to be expected during full fixed appliance mechanotherapy in Class II Division 1 malocclusions treated with premolar extractions when mandibular incisor retraction was not part of the treatment plan. The material consisted of pretreatment and posttreatment cephalometric films and dental casts of 70 Class II Division 1 malocclusion patients (33 males and 37 females) treated with the preadjusted edgewise appliances. The mandibular first premolars were extracted in 31 subjects, and the mandibular second premolars were extracted in 39.
