ameloblastomas are slow growing, locally invasive, benign odontogenic tumors of an epithelial origin, accounting for approximately 1% of all oral tumors. a 40-year-old man presented with a chief complaint of a swelling over the left side of his face of 4 years’ duration. on examination, gross facial asymmetry was detected, and a well-defined swelling was noted intraorally involving the left max...

JCO/APRIL 2003 G patients with dentofacial deformities characterized by either a midfacial deficiency or true mandibular prognathism are perhaps the most challenging cases for the clinician to manage. In patients with midfacial deficiency, the current clinical protocol calls for orthopedic maxillary protraction by means of elastics to either an extraoral facemask or a chin cup.1,2 A maxillary e...

BACKGROUND The purpose of this controlled study was to investigate indirect effects on mandibular arch dimensions, 1 year after rapid palatal expansion (RPE) therapy. METHODS Thirty-three patients in mixed dentition (mean age 8.8 years) showing unilateral posterior crossbite and maxillary deficiency were treated with a RPE (Haas type) cemented on the first permanent molars. Treatment protocol...

During a 1981 presentation at an American Association of Orthodontists meeting, David Turpin recommended that early treatment should be considered for young patients who present with positive factors such as convergent facial type, anteroposterior functional shift, symmetrical condyle growth, mild skeletal disharmony, some remaining growth, good cooperation, no familial prognathism, and good fa...

BACKGROUND Severe maxillary hypoplasia in cleft patients is caused by a combination of pathogenic and iatrogenic factors. In this work, the authors investigated anatomical deficiencies in dentition for predicting Le Fort I maxillary advancement surgery for severe maxillary hypoplasia in cleft patients. METHODS Cleft lip-cleft palate and cleft palate patients older than 14 years of age were re...

Objectives: Skeletally mature patients with transverse deficiency are best treated surgically assisted rapid palatal expansion (RPE) procedure. Recent studies have shown that microimplant-assisted RPE (MARPE) appliances can be effective in achieving skeletal young adults. This retrospective study aimed to evaluate the and dental alveolar changes response treatment MARPE three types of anteropos...
