Effects of Three Different Orthodontic Treatment Methods on the Stability of Mandibular Incisor Alignment.

Objective: To compare the effects of extraction, non-extraction and air-rotor stripping treatments on mandibular dental arch dimensions, lower incisor positions and evaluate their effects on the stability of the treatment.

Study Design: The sample consisted of 44 patients with Class I malocclusion and moderate crowding including 15 patients treated with extraction, 13 with air-rotor stripping (ARS), and 16 with non-extraction treatment. The records were taken at pretreatment (T0), end of active orthodontic treatment (T1), minimum 3 years post-treatment (T2).

Long-term stability of surgical-orthodontic treatment for skeletal Class III malocclusion with mild asymmetry.

Skeletal Class III malocclusion with mandibular prognathism is often associated with mandibular asymmetry, and patients with Cl III deformity and asymmetry may undergo orthognathic surgery to improve facial function and esthetics. However, the long-term stability of mandibular setback surgery has been considered "problematic". We report a 25-year-old female patient who was diagnosed as having a skeletal Class III relationship, mandibular asymmetry and unilateral crossbite.

Soft tissue effects of three different Class II/1-camouflage treatment strategies.

Objective: Aim of this retrospective study was to compare soft tissue effects of Class II treatments with the forsus fatigue resistant device (FRD), the pendulum appliance, and the extraction of two maxillary premolars, all of which were combined with pre-adjusted fixed appliances.

Patients And Methods: The sample of 54 patients with Class II malocclusions was divided in three groups: group I patients (mean age = 15.91 years) were treated with the FRD concurrently used with fixed appliances; group II patients (mean age = 16.

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.

Treatment of Class II Division 2 Malocclusion Using the Forsus Fatigue Resistance Device and 5-Year Follow-Up.

This case report presents the treatment of a 14-year-and-8-month-old boy with Class II division 2 mandibular retrusion, severe deep bite, and concave profile. The Forsus fatigue resistance device (FRD) was effective in correcting both skeletal and dental parameters. At 5-year posttreatment follow-up, the teeth were well aligned and the occlusion was stable.

Orthognathic Treatment of Skeletal Class III Malocclusion with Severe Facial Asymmetry.

A 26-year, 9-month-old woman had chief complaints of mandibular protrusion and facial asymmetry. Extraoral examination indicated mandibular deviation to the left side, severe facial asymmetry, and a concave profile. Because the patient had a vertical maxillary height difference and an occlusal plane cant together with maxillary retrusion, a differential downgraft and advancement surgery with Lefort I osteotomy was planned.

Upper airway changes after Xbow appliance therapy evaluated with cone beam computed tomography.

Objective: To determine the treatment effects of the Xbow appliance on the upper airway dimensions and volume using cone-beam computed tomography (CBCT); to evaluate the cephalometric changes in the skeletal and dental structures of the skeletal Class II patients.

Influence of two different bracket base cleaning procedures on shear bond strength reliability.

Purpose: To search if the shear bond strengths of brackets would change after two different base-cleaning procedures such as sandblasting or carbide bur cleaning, and to determine if a previously bonded tooth surface had any effect on bond strength.

Materials And Methods: A total of 120 new brackets were first bonded to 120 extracted premolars and then debonded and bond strength was recorded. The debonded brackets were divided into two groups and recycled either by sandblasting or tungsten-carbide bur cleaning.

Objective: To compare the dental arch relationships of Turkish patients with complete unilateral cleft lip and palate (UCLP) with the results reported for participants in the Eurocleft study.

Patients: Study models of 109 patients with complete UCLP from five university clinics in Turkey were evaluated (clinic A = 25 patients, clinic B = 23 patients, clinic C = 20 patients, clinic D = 21 patients, and clinic E = 20 patients). The mean age of the patient cohort was nine years old (range = 8-11 years old), and the cohort was born between 1976 and 1990.

Effect of low-level laser therapy (LLLT) on orthodontic tooth movement.

The aim of this study is to evaluate the effects of low-level laser therapy (LLLT) on (1) the velocity of orthodontic tooth movement and (2) the nitric oxide levels in gingival crevicular fluid (GCF) during orthodontic treatment.

Reimplantation of an inverted maxillary premolar: case report of a multidisciplinary treatment approach.

Inversion of premolars is an extremely rare condition, which usually requires extraction. This case report describes the inversion of an impacted maxillary second premolar in an 11-year-old male, and the multidisciplinary treatment approach for bringing the tooth into a normal position within the arch. In order to provide sufficient space for surgical reimplantation of the tooth, the mesially-drifted neighbouring maxillary first molar was first endodontically treated, followed by orthodontic distalization of the tooth.

Tridimensional evaluation of maxillary and mandibular movements in orthognathic surgery.

For better evaluation of long-term results of orthognathic surgery, movements of osteotomized maxillary and mandibular segments should be documented both in x-, y-, and z-axes and in terms of kind of movement (either linear or rotational movements). Lateral cephalometric, anteroposterior cephalometric, and submentovertex radiographs of 14 patients, treated with combined orthodontic and surgical treatment for skeletal class III malocclusion, were reevaluated retrospectively to demonstrate the applicability and usefulness of defined parameters in four maxillary and five mandibular movements. There was no clinically significant relapse in the follow-up period of 6 months in any of the patients.

Use of three-dimensional medical modeling methods for precise planning of orthognathic surgery.

Stereolithographic (medical rapid prototyping) biomodeling allows three-dimensional computed tomography to be used to generate solid plastic replicas of anatomic structures. Reports in the literature suggest that such biomodels may have a use in maxillofacial surgery, craniofacial surgery, orthopedics, neurosurgery, otology, vascular, and nasal research. A prospective trial to assess the usefulness of biomodeling in orthognathic surgery has been performed.

Evaluation of the treatment changes of functional posterior crossbite in the mixed dentition.

Introduction: Functional posterior crossbite (FPXB) malocclusion is frequently seen in the deciduous or mixed dentition. It is often accompanied by lateral mandibular shift and mandibular midline deviation because of the reduction in the width of the maxillary dental arch. The aims of this prospective study were to examine in detail the morphologic, skeletal, dental, and functional effects of FPXB, and the effects of maxillary expansion treatment with quad-helix appliance.

Lower incisor retraction with a modified corticotomy.

This case report demonstrates the orthodontic treatment facilitated with a new conservative corticotomy technique to shorten the treatment time during lower incisor retraction. The patient was a 22-year-old woman with protrusive profile, severe anterior crowding, an anterior crossbite, and Class III dental relationship. Orthodontic treatment consisted of the extraction of four first premolars with maximum anchorage.
