The aim of this study was to review recent randomized clinical trials (RCTs) dealing with the effectiveness of various modalities of orthopaedic/orthodontic expansion of maxillary arches with crossbite and the associated 6 month post retention stability. The study selection criteria included RCTs involving subjects with maxillary deficiency with crossbite, with no limits of age. The authors sea...

The aim of this study was to investigate long-term effects induced by rapid maxillary expansion (RME), followed by comprehensive orthodontic treatment, in a sample of 42 patients compared with normal growth changes in a sample of 20 subjects. Treated subjects underwent Haas-type RME with 2 turns a day (0.25 mm per turn) until the expansion screw reached 10.5 mm (about 21 days). The Haas expande...

The purpose of this study was to evaluate the effects of a modified reverse headgear force applied with a facebow on the dentofacial structures of patients with skeletal Class III malocclusions characterized by maxillary retrognathism. Thirty individuals before the pubertal peak and in the mixed dentition were selected. Fifteen subjects (seven males, eight females, mean age 9.2 years) who forme...

INTRODUCTION Few in vivo studies have investigated the effect of maxillary expansion on strabismus; however, some in vitro studies hypothesized that changes in the palatal width obtained with rapid maxillary expansion appliances could involve other bone structures that contain blood vessels and nerves conveying to the orbital cavity. The present case report seems to support that hypothesis, eve...

AIM The aim of this report is to present the management of the maxillary deformity and subsequent implant therapy of a case with β-thalassemia major. BACKGROUND β-thalassemia is a hematologic disorder that results from the abnormality of the β-globulin chain synthesis. The best known thalassemia-induced dentofacial problem is the maxillary enlargement, and this undesirable growth of maxilla a...

INTRODUCTION Maxillary transverse deficiency is a highly prevalent malocclusion present in all age groups, from primary to permanent dentition. If not treated on time, it can aggravate and evolve to a more complex malocclusion, hindering facial growth and development. Aside from the occlusal consequences, the deficiency can bring about serious respiratory problems as well, due to the consequent...

Objective: To evaluate the efficacy of nickel-titanium expander for maxillary expansion and the skeletal and dental changes associated with the expander in operated cleft palate patients. Materials and methods: Ten male unilateral cleft lip and palate patients in the age group of 9 to 13 years with transverse maxillary deficiency and with no history of bone grafting procedure, were selected fro...

background and aims. class iii malocclusions are considered as one of the most complex orthodontic problems to diagnose and treat. numerous studies have been conducted to determine the morphologic characteristics of craniofacial complex in patients with this malocclusion. the aim of this study was to determine the dentofacial characteristics of class iii malocclusion in mashhadian adults. mater...
