BACKGROUND The purpose of this study was to confirm the utility of a corrected cephalometric analysis to facilitate the planning of distraction osteogenesis with Le Fort III osteotomy for syndromic craniosynostosis. METHODS This prospective study involved 4 male and 2 female patients (mean patient age, 8 years 9 months; age range, 4 years 6 months to 13 years 2 months) with Crouzon syndrome w...

Cephalometric analyses are useful for planning and provision of orthodontic treatment. A and B points are used to resemble the anterior part of maxilla and mandible and N represents the anterior part of the cranial base. The position of N may influence measurements of SNA, SNB, and ANB and changes of N in the antero-posterior plane are thought to have a larger influence on the above measurement...

Abstract Background The position of infrazygomatic crest bone screws is an important consideration in determining the success orthodontic treatment. aim this study was to compare (IZC) relation skeletal and dental parameters using postero-anterior (PA) cephalograms cone beam computed tomography (CBCT). Methods A CBCT scan a PA cephalogram were taken 19 patients (8 males; 11 females) after IZC s...

Introduction: Accurate determination of skeletal maturity and remaining growth is crucial to many orthodontic, orthognathic and dental implant timing decision. Cervical vertebral stages and hand-wrist radiographs are currently used to identify peak mandibular bone growth. These are highly subjective techniques that not only involve radiographic exposure but also lack the ability to determine th...

The purpose of this study was to evaluate how incremental information obtained from different types of diagnostic records contributes to the determination of orthodontic treatment decisions. Pretreatment records of 57 orthodontic patients were assessed by five orthodontists who were part-time faculty members and also in private practice. This sample consisted of dental school orthodontic patien...

OBJECTIVE To perform an evidence-based medicine review of the literature describing outcomes of hypopharyngeal surgery in obstructive sleep apnea. DESIGN We performed a MEDLINE search of English-language articles or abstracts using the keywords sleep and surgery in combination with any of the following terms: hypopharynx, tongue, tongue base, epiglottis, genioglossus, advancement, mortised, g...

The aims of this study were to determine the changes in the dentofacial structures of Class II division 1 mandibular retrognathic patients treated with bilateral extraction of the upper first premolars, and to compare pre- and post-treatment values with the cephalometric norms of Anatolian Turkish adults. The Class II division 1 subjects included 20 males and 33 females (mean age: 17.08 +/- 1.0...

The aim of the present study was to clarify the skeletal treatment effects induced by activator treatment. Fifty actively growing patients with Class II division 1 malocclusions were treated with an activator appliance. A control group consisting of longitudinal growth data from 20 patients (untreated Class II division 1 malocclusions) was used to eliminate possible differences in growth patter...

BACKGROUND The study aims to associate serum insulin-like growth factor-1 (IGF-1) levels with cervical maturation stages (CS) 3, 4, and 5 on lateral cephalogram in male subjects and to find out peak serum IGF-1 levels among these three stages. METHODS The study was conducted on 45 male subjects who were at skeletal maturation stage CS-3, CS-4, and CS-5. Subjects were selected using simple ran...

Purpose: The purpose of this study was to assess skeletal stability after mandibular setback surgery with and without an inter-maxillary fixation (IMF) screw. Subjects and Methods: The subjects consisted of 40 patients with mandibular prognathism. The subjects underwent sagittal split ramus osteotomy (SSRO) with titanium plate fixation and were divided into two groups, one with and one without ...
