The aim of the present epidemiologic study was to obtain representative basic data on the frequency, extent and age-dependence of malocclusions in the deciduous and early mixed dentition. The developmental tendencies of specific malocclusions were investigated from the aspect of orthodontic prevention. The collective comprised 8,864 preschool and schoolage(More)
OBJECTIVE Type and prevalence rates of the symptoms of Hoffmeister's "genetically determined predisposition to disturbed development of the dentition" were studied in patients with clefts. PATIENTS Data of 263 patients with nonsyndromic clefts of lip (alveolus and palate) or isolated cleft palates were examined in a retrospective study. SETTING The(More)
Background: The relationship between maxillary canine displacement and the simultaneous occurrence of “genetically determined predisposition to disturbed development of the dentition” as defined by Hoffmeister [20] was investigated in 675 patients. Patients and Methods: Panoramic radiographs taken of each patient during the first and the second mixed(More)
In 417 children aged 3 to 8 years with cleft lip, jaw and palate, the prevalence of caries and the degree of treatment of deciduous teeth were compared with those of 258 cleft patients who had received preventive treatment. The prevalence of caries was reduced by more than 50% by preventive treatment. A statistically significant effect of the cleft on the(More)
The prevalence of symptoms of Hoffmeister’s “genetically determined predisposition to disturbed development of the dentition” as studied in patients with true skeletal Class III malocclusion; results of the study were compared with those found in the scientific literature regarding samples from the normal population and from orthodontic patients. The(More)
AIM Presentation of an orthopaedic/orthodontic treatment protocol within the framework of complex rehabilitation of patients with clefts of lip, alveolus and palate. Presurgical orthopaedic treatment aims at reduction of cleft size by guiding growth and functional rehabilitation. Long-term results of maxillary development and occlusion at young adult age(More)
OBJECTIVE To compare the hyoid bone position in patients with clefts of lip, alveolus, and palate with orthodontic patients with no cleft. DESIGN Retrospective cephalometric long-term study. PATIENTS Lateral cephalograms of 23 patients with a complete unilateral cleft were compared with those of 24 orthodontic patients with no cleft with an Angle class(More)
The aim of this study was to analyze sagittal and vertical dentofacial dimensions in subjects with normal occlusions during the juvenile and adolescents age periods to establish age- and gender-specific lateral cephalometric standard values for Germans during their active growth period. The study group consisted of a sample of 32 untreated subjects with(More)
Background and Aim: Hoffmeister was the first to recognize the common genetic origin of structurally very varied disturbances in the development of the dentition. He coined the term "microsymptoms of a genetically determined predisposition to disturbed development". The purpose of the present study was to examine the incidence of those microsymptoms in a(More)
We analyzed the incidence of eruption disorders in 6-year molars during the first phase of mixed dentition, and then determined the risks for later dental arch development according to specific combinations of orthodontic malocclusions. We, thus, aimed to derive potential conclusions for preventative orthodontics. In this cross-sectional study, 8,041(More)
