Transverse maxillomandibular discrepancies are a major component of several malocclusions. Orthopedic and orthodontic forces are used routinely to correct a maxillary transverse deficiency (MTD) in a young patient. Correction of MTD in a skeletally mature patient is more challenging because of changes in the osseous articulations of the maxilla with the adjoining bones. Surgically assisted rapi...

The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segment...

Recession of the midface is a relatively common condition that can have a negative impact on facial and nasal aesthetic appearance, and it poses a challenge to plastic surgeons. In cases with generalized maxillary retrusion and/or malocclusion, bone advancement surgery is required, but in localized cases, mostly seen in cleft lip patients, the quest is for an ideal material and a proper techniq...

Ectopic eruption is the abnormal eruption of a permanent tooth that often causes root resorption of an adjacent primary tooth which can be noted during routine dental radiographic evaluation. The mesial eruption of the permanent first molar may be a local eruption problem or may indicate developmental arch circumference deficiency requiring further consideration. Early treatment is mandatory to...

A 19-year-old man presented for correction of a malocclusion that included a transverse maxillary deficiency. The patient was informed that he required orthognathic surgery to expand his upper jaw and correct his malocclusion, but he refused surgical expansion. Recent evidence indicates that rapid palatal expansion can be used without surgery in young adults; the decision was therefore made to ...

BACKGROUND This study aimed to evaluate three-dimensional changes in mandibular position after surgically assisted rapid maxillary expansion (SARME). METHODS A retrospective study was carried out with tomographic records of 30 adult patients with maxillary transverse deficiency who underwent SARME. Cone beam computed tomography scans were obtained preoperatively (T1), after expansion (T2) and...

Received: 13 March 2008 Accepted: 27 August 2008 Abstract: A 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. It was a rare case that represented approximately horizontal view in panoramic radiograph. The severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatme...

Class III malocclusion is a consequence of maxillary deficiency and/or mandibular prognathism, often resulting in an anterior crossbite and a concave profile.1 Young patients with maxillary hypoplasia are usually treated with a facemask: heavy anterior traction is applied on the maxilla to stimulate its growth and to restrain or redirect mandibular growth. Forward and downward movement of the m...

INTRODUCTION The aim of this prospective clinical study was to evaluate the skeletal, dentoalveolar, and soft-tissue effects of maxillary protraction with miniplates compared with conventional facemask therapy and an untreated Class III control group. METHODS Forty-five subjects who were in prepubertal or pubertal skeletal growth periods were included in the study and divided into 3 groups of...

Introduction: Patients with transverse maxillary deficiency may have unilateral or bilateral posterior crossbite, crowded and rotated teeth narrow palate. The treatment for adults is surgically assisted rapid expansion, a procedure that results in changes not only to bones, but also teeth, nasal cavity, air space, lips surrounding soft tissues. Objective: This study evaluated dentoskeletal pati...
