UNLABELLED Four premolar extractions is a successful protocol to treat Class I malocclusion, but it is a less efficient way when compared with other Class II treatment protocols. OBJECTIVE The objective of this study was to evaluate the influence of anteroposterior discrepancy on the success of four premolar extractions protocol. For that, treatment efficiency of Class I and complete Class II...

This report describes the correction of a clinical case of malocclusion with anteroposterior discrepancy and transverse, sagittal and vertical deficiencies. A nonextraction technique was used to preserve space in the dental arches and control facial growth for the correction of the sagittal skeletal relationship and of overbite. The mechanics adopted efficiently corrected malocclusion: all func...

The purpose of this study was to evaluate the Denture Frame Analysis. This adjunctive cephalometric analysis of the lateral headfilm was introduced in Japan, but no data exist for the Caucasian population at present. One-hundred-and-six Caucasians were randomly selected and assigned to one of four groups, according to their malocclusion: Angle Classes I, II, and III, and anterior open bite. Sta...

This case report describes the successful treatment of a 26-year-old Caucasian male with skeletal and dental Class III malocclusion associated with mild maxillary and mandibular crowding. The patient had anteroposterior and transverse discrepancies with a reverse overjet and bilateral posterior crossbites. The nonextraction treatment plan included aligning and leveling of the teeth in both arch...

BACKGROUND The prevalence of malocclusion in modern population is higher than that in the excavated samples from the ancient times. Presently, the prevalence of juvenile malocclusion in the early stage of permanent teeth is as high as 72.92% in China. This study aimed to observe and evaluate the prevalence and severity of malocclusions in a sample of Xia Dynasty in China, and to compare these f...

Skeletal Class III malocclusion, with its unpredictable and unfavorable nature, has been characterized by a growth pattern with doubtful prognosis regarding orthodontic mechanics, even when performed early. For a long time, Class III malocclusion was regarded as a synonym of mandibular prognathism, regardless of the affected skeletal structures. Mandibular growth, essentially determined by gene...

Objectives: The purpose of this study was to evaluate the relationship between psychosociocultural factors and dental malocclusion, facial appearance, body perception. Material Methods: carried out with participation 112 female 113 male individuals ages 18 25. Individuals were asked answer Rosenberg Self-Esteem Scale, Physical Appearance Comparison Scale Revised, Sociocultural Attitudes Towards...

Objective: To evaluate the psychosocial impact of malocclusion and self-esteem in adolescents Amazon region. Material Methods: A cross-sectional study was carried out with 212 12-year-old enrolled all public schools Boca do Acre (Amazonas, Brazil). Psychosocial Impact Dental Aesthetics Questionnaire (PIDAQ) assessed malocclusion. The self-perception need for orthodontic treatment evaluated by A...

The present case report describes the orthodontic treatment of a young adult patient (18y / 1m), Class III skeletal malocclusion, with mandibular prognathism and significant dental compensation. The canine relation was Class III, incisors with tendency to crossbite and open bite, moderate inferior crowding, and concave profile. Skeletal correction of malocclusion, facial profile harmony with sa...

For the cleft patient presenting in adolescence with a jaw discrepancy and malocclusion, misinformation and limited available surgical and dental expertise often prevents a favorable facial reconstruction and dental rehabilitation. A major advantage of the modified Le Fort I osteotomy is its ability to simultaneously close cleft dental gap(s), resolve oronasal fistulas, manage skeletal defects,...
