Computed tomography assessment of temporomandibular joint position and dimensions in patients with class II division 1 and division 2 malocclusions.

Background: This study aimed to investigate and compare the positions and dimensions of the temporomandibular joint and its components, respectively, in patients with Class II division 1 and division 2 malocclusions.

Material And Methods: Computed tomography images of 14 patients with Class II division 1 and 14 patients with Class II division 2 malocclusion were included with a mean age of 11.4 ± 1.

Comparing the effects of Essix and Hawley retainers on the acoustics of speech.

Objective: The aim of this study was to compare the effects of two retainer types (Essix and Hawley) on speech performance.

Subjects And Methods: The speech articulation of 30 patients was evaluated prospectively. Five patients did not appear during the follow-up periods.

Evaluation of maxillary arch dimensional and inclination changes with self-ligating and conventional brackets using broad archwires.

Introduction: Our objective was to comparatively evaluate different bracket types (conventional, active self-ligating, and passive self-ligating) combined with broad archwires in terms of maxillary dental arch widths and molar inclinations.

Methods: Forty-six patients aged 13 to 17 years with moderate maxillary and mandibular crowding and a Class I malocclusion were included in this prospective clinical trial. The primary outcome measures were changes in maxillary arch width dimensions and molar inclinations.

Three-dimensional assessment of the temporomandibular joint and mandibular dimensions after early correction of the maxillary arch form in patients with Class II division 1 or division 2 malocclusion.

Objective: This study aimed to assess three-dimensional changes in the temporomandibular joint positions and mandibular dimensions after correction of dental factors restricting mandibular growth in patients with Class II division 1 or division 2 malocclusion in the pubertal growth period.

Methods: This prospective clinical study included 14 patients each with Class II division 1 (group I) and Class II division 2 (group II) malocclusions. The quad-helix was used for maxillary expansion, while utility arches were used for intrusion (group I) or protrusion and intrusion (group II) of the maxillary incisors.

Evaluation of the soft tissue treatment simulation module of a computerized cephalometric program.

Objective: The purpose of this study is to compare the accuracy of the treatment simulation module of Quick Ceph Studio (QCS) program to the actual treatment results in Class II Division 1 patients.

Design: Retrospective study.

Materials And Methods: Twenty-six skeletal Class II patients treated with functional appliances were included.

An assessment of conventional and self-ligating brackets in Class I maxillary constriction patients.

Objective: To evaluate two different treatment systems with regard to incisor position, transverse dimension changes in maxillary arch, changes in maxillary molar inclinations, clinical periodontal parameters, and pain intensity in patients with a Class I malocclusion.

Materials And Methods: Seventeen patients (with a mean age of 14.5 years) underwent orthodontic treatment with the Roth prescribed edgewise bracket systems after expanding the maxillary arch with a quad-helix appliance, and 16 patients (with a mean age of 14.

Effects of Hawley retainers on consonants and formant frequencies of vowels.

Objective: To assess (1) whether Hawley retainers cause speech disturbance and (2) the duration of speech adaptation to Hawley retainers with objective and subjective tests.

Materials And Methods: Twelve adolescents, aged 11.11 to 18.

Effects of 2 types of facemasks on condylar position.

Introduction: The aim of this study was to compare Delaire and Grummons protraction facemasks with a new articulator system (Amtech MG1, American Technologies, Brazil) that can record condylar positions.

Methods: Thirty-four patients treated with protraction facemask therapy were divided into 2 groups; 18 were treated with the Delaire facemask (DFM) and 16 with the Grummons facemask (GFM). The observation periods were 8.

Occlusal characteristics of deaf-mute individuals in the Turkish population.

Objectives: To classify and determine the occlusal characteristics of deaf-mute individuals and its gender distribution in the Turkish population.

Methods: For this study, 213 deaf-mute individuals (155 boys and 58 girls) were evaluated. The age range was between 10-24 years, and the mean age was 16.

Evaluation of posttreatment changes in Class II Division 1 patients after nonextraction orthodontic treatment: cephalometric and model analysis.

Background: The aim of this retrospective study was to evaluate changes in patients with Class II Division 1 malocclusions treated with cervical headgear and full fixed orthodontic appliances and without extractions.

Methods: Lateral cephalograms and dental casts of 18 patients were obtained at the beginning and the end of treatment and at the postretention period. Pretreatment records were taken at 11.

Evaluation of dental arch width and form changes after orthodontic treatment and retention with a new computerized method.

The purpose of this study was to evaluate longitudinal arch width and form changes and to define arch form types with a new computerized method. Maxillary and mandibular models of 21 Class II Division 1 patients were examined before treatment (T(0)), after treatment (T(1)), and an average of 3 years after retention (T(2)). Arch width measurements were made directly on scanned images of maxillary and mandibular models.

Changes in alveolar bone thickness due to retraction of anterior teeth.

In cases of bimaxillary protrusion, extraction of 4 premolars and orthodontic treatment with retraction of the anterior teeth is a widely used approach. However, there is controversy over whether the changes that occur in the anterior alveolar bone always follow the direction and quantity of tooth movement. Nineteen patients with dentoalveolar bimaxillary protrusion treated by extracting the 4 first premolars were evaluated with lateral cephalograms and computed tomography (CT).
