OBJECTIVE To test the hypothesis that maxillary protraction appliances (MPA) have no effect on the size of the upper airway passage and craniofacial structures in adolescent patients. MATERIALS AND METHODS Twenty patients (5 male and 15 female; mean age 11.5 years) with skeletal Class III malocclusion were included in this study. The records of all(More)
OBJECTIVE The objectives of the present study were to investigate the prevalence and characteristics of supernumerary teeth and evaluate the associated pathologies and treatment protocol in a Turkish patient population. STUDY DESIGN A retrospective study was performed using full-mouth periapical and panoramic radiographs of 3491 patients (2146 females and(More)
In the present study, the relationships among ANB, Wits, AF-BF, and APDI measurements used in the assessment of the anteroposterior jaw disorders were examined on the cephalometric radiographs of 63 male and 82 female subjects, and high correlations were found among them. Furthermore, relationships were explored between these parameters and some(More)
SUMMARY The dentoskeletal effects of maxillary protraction (MP) therapy have been extensively investigated, while those relating to soft tissue profile changes are limited. Thus, the aim of this study was to determine the degree of soft tissue profile changes following MP therapy. The material consisted of the cephalometric films of 24 female subjects(More)
In the present study, pharyngeal size was investigated on the lateral cephalometric head films of 90 subjects, 45 males and 45 females, having different ANB angles. All of the subjects were aged 13 to 15 years. The films were taken at natural head position, and all were divided into three groups according to the ANB angle: ANB angles smaller than 1 degree,(More)
INTRODUCTION Posterior crossbite is defined as an abnormal buccolingual relationship between opposing posterior teeth including the canines in centric occlusion. The most common form of posterior crossbite is unilateral with a functional shift of the mandible toward the crossbite side. Lateral shift of the mandible in functional crossbite patients results(More)
OBJECTIVE Rapid maxillary expansion (RME) is a dentofacial orthopedic treatment procedure which has been routinely used in young patients. Main goal of RME is to correct the existing posterior crossbite and to widen the maxilla and maxillary dental arch. However, a concomitant and contributing benefit of this procedure is an improvement on nasal airway(More)
INTRODUCTION Conductive hearing loss is affected by physical changes imposed on the mechanical system of the outer or middle ear. Maxillary expansion can affect conductive hearing loss, and the changes have been investigated with pure-tone audiograms. Semirapid and slow methods of maxillary expansion have some advantages over rapid maxillary expansion, but(More)
The objective of the present study was to evaluate short-term soft tissue changes caused by rapid maxillary expansion (RME) in 18 subjects (15 females and 3 males) (mean age 13 years 6 months) with a bilateral posterior crossbite. Lateral cephalograms of the patients were obtained at three different time points: before RME (T1), after maxillary expansion(More)
The aim of the present study was to investigate the effects of two different force levels on the amount of total and daily tooth movement in rabbits and to determine whether any increase in tooth movement is equal to the increase in force. Forces of approximately 20 (group I) and 60 (group II) g (19.6 and 58.8 cN) were applied to the upper central incisors(More)
