A Novel Approach for the Reconstruction of Premaxilla by Archwise Distraction in Bilateral Cleft Lip and Palate.

Interdental distraction osteogenesis has been introduced as a successful treatment protocol for repairing large clefts. In this article, a new method for reconstruction of the premaxilla in 2 bilateral cleft lip and palate patients is introduced. The aim was to distract the lateral segments through the curve of the dental arch, achieve complete closure of the gaps, and use the premaxilla as a bone graft.

Reconstruction of Premaxilla With Alveolar Distraction Osteogenesis in a Patient With Complete Cleft Lip and Palate: A Case Report.

This case report presents an early clinical evaluation of a patient with bilateral cleft lip and palate (CLP) treated with ArchWise Distraction Osteogenesis Technique and Appliance. A 16-year-old patient with a bilateral CLP had a chief complaint of missing upper anterior teeth and poor aesthetics. The patient had class III skeletal and dental relationships, maxillary hypoplasia, maxillary posterior arch constriction, premaxillary deficiency, multiple missing teeth due to an alveolar cleft, and a concave profile.

Anterior open-bite treatment by means of zygomatic miniplates: a case report.

This case report presents the treatment of a patient with skeletal Cl II malocclusion and anterior open-bite who was treated with zygomatic miniplates through the intrusion of maxillary posterior teeth. A 16-year-old female patient with a chief complaint of anterior open-bite had a symmetric face, incompetent lips, convex profile, retrusive lower lip and chin. Intraoral examination showed that the buccal segments were in Class II relationship, and there was anterior open-bite (overbite -6.

Hounsfield Units: a new indicator showing maxillary resistance in rapid maxillary expansion cases?

Objective: To determine if density measurements of several maxillary regions in Hounsfield Units (HU) and outcomes of rapid maxillary expansion (RME) are correlated. Is correlation powerful enough to give us direct information about maxillary resistance to RME?

Materials And Methods: Twenty-two computed tomographic (CT) scans (14 years) are used in this archive study. Two CT records were collected, one before RME (T1) and one after 3 months of retention period (T2).

Dimensional changes of maxillary sinuses and pharyngeal airway in Class III patients undergoing bimaxillary orthognathic surgery.

Objective: To evaluate the pharyngeal airway and maxillary sinus volume changes after mandibular setback surgery combined with maxillary advancement and/or impaction surgery.

Materials And Methods: Seventeen Class III skeletal patients (11 females, 6 males) who required bimaxillary orthognathic surgery were selected. Volumetric measurements were performed using cone beam computed tomography (CBCT) scans preoperatively and 3.

Noncompliance open-bite treatment with zygomatic anchorage.

Objective: To evaluate the dentoalveolar and skeletal effects of the new-generation open-bite appliance.

Subjects And Methods: The study group was composed of 11 subjects with a mean age of 19.5 years who underwent intrusion of the posterior dentoalveolar segment using an open-bite appliance supported by bilateral zygomatic implants.

A new face by combined surgery for patients with complex dentofacial deformity.

Background: This article aims to present and discuss 53 patients who received a new identity because of major changes to the face after treatment with bimaxillary osteotomy, concomitant maxillomalar augmentation, genioplasty, and rhinoplastic procedures for their complex dentofacial skeletal deformity and class 3 malocclusion.

Methods: During a 12-year period (January 1993 to April 2005), more than 500 patients with dentofacial deformities and malocclusions have undergone orthognathic surgery performed by a team consisting of the same plastic surgeons and orthodontists. Among this group, 53 patients (30 women and 23 men) underwent surgery for both aesthetic and functional concerns.

New generation open-bite treatment with zygomatic anchorage.

This technical note aims to present the fabrication and application of a new generation of posterior intrusion appliances using zygomatic anchorage. The use of zygomatic anchorage enables en masse impaction of the posterior segment without any side effects such as labial flaring. A 14-year-old, female Class II patient with an anterior open bite was treated with a new generation posterior intrusion appliance.

Apical root resorption of maxillary first molars after intrusion with zygomatic skeletal anchorage.

The aim of this study was to evaluate radiographically the apical root resorption of maxillary first molars after their intrusion was done using zygomatic miniplates as skeletal anchorage in open-bite cases. The study group comprised 16 consecutively treated open-bite cases who had received special titanium miniplates in their zygomatic bones for use as anchorage to apply orthodontic intrusive forces to the maxillary posterior region. The control group consisted of 16 patients, who were matched regarding age, sex, and treatment duration but who had undergone fixed orthodontic treatment without intrusion mechanics for molars.

Zygomatic anchorage for en masse retraction in the treatment of severe Class II division 1.

An adult female patient who presented with a severe Class II division 1 malocclusion was treated by en masse retraction of upper anterior teeth against zygomatic anchorage. This case report describes the surgical and orthodontic procedures followed during the treatment. En masse retraction of the six anterior teeth by using zygomatic bone anchorage proved to be an efficient method for the correction of a severe overjet problem.

The use of skeletal anchorage in open bite treatment: a cephalometric evaluation.

The aims of the present study were to assess the effectiveness of skeletal anchorage for intrusion of maxillary posterior teeth, to correct open bite malocclusion, and to evaluate the usage of titanium miniplates for orthodontic anchorage. Anterior open bite is one of the most difficult malocclusions to treat orthodontically. Currently, surgical impaction of the maxillary posterior segment is considered to be the most effective treatment option in adult patients.

Bodily distalization of molars with absolute anchorage.

Palatal implants have been used over the last two decades to eliminate headgear wear and to establish stationary anchorage. In this case report, the stability of a palatal implant for distalization of molars bodily and for anchorage maintenance was assessed. The implant was a stepped screw titanium (4.

Evaluation of the relationship between the anterior component of occlusal force and postretention crowding.

The aim of this study was to investigate whether a relationship exists between the anterior component of occlusal force (ACF) and postretention crowding in the mandibular incisor area. The study group comprised 32 adults who had undergone fixed orthodontic treatment in the department clinic at Marmara University in Istanbul, Turkey. In 13 subjects, the mandibular arch was treated without extractions; in 19, it was treated with bilateral first premolar extractions.

Effect of varying the force direction on maxillary orthopedic protraction.

The aim of this study was to examine the effect of varying the force direction on maxillary protraction. A total of 20 patients with class III maxillary retrognathism were randomly divided into two groups. Group 1 was comprised of nine patients with a mean age of 8.
