Changes in the dental arches and dentition between 25 and 45 years of age
Dental arches Permanent Longitudinal Midadulthood
2009/1/9
The purpose of this longitudinal investigation was to study changes in the dental arches and dentition that occur in midadulthood in an untreated, normal sample. The subjects had Class I molar and...
The accuracy of video imaging for mixed dentition and adolescent treatment
Video imaging Growing patients Diagnosis Communication medium
2009/1/8
The purpose of this study was to evaluate the accuracy of computerized video imaging in predicting the soft tissue outcome of growth modification treatment for skeletal Class II malocclusions. Pre...
Case Report：Modified use of the Jasper Jumper appliance in a skeletal Class II mixed dentition case requiring palatal expansion
Jasper Jumper Skeletal Class II Palatal expansion
2009/1/8
The Jasper Jumper appliance provides a method of Class II correction with an active force component that the patient cannot remove. A modification of classic Jasper Jumper usage is illustrated in a ...
Dental arch asymmetry in the mixed dentition
Dental arch Asymmetry Children Mixed dentition
2009/1/7
Many orthodontists evaluate dental asymmetry clinically by comparing landmarks on the occlusal surfaces of dental casts. The purpose of this study was to quantify and describe maxillary and mandib...
Mixed dentition analysis for Hong Kong Chinese
Mixed dentition analysis Prediction equations Probability tables
2009/1/7
Using simple linear regression analyses, prediction equations for the combined mesiodistal crown diameters of canines and premolars based on lower incisor size were generated from 97 Hong Kong Chi...
Longitudinal occlusal changes from primary to permanent dentition in children with normal primary occlusion
Normal occlusion Longitudinal study Primary dentition Permanent dentition
2009/1/7
This purpose of this research was to examine the stability of normal occlusion during the transition from primary to permanent dentition. The sample consisted of 128 children (83 boys and 45 girls) ...
The compensatory mechanism in high-angle malocclusions：A comparison of subjects in the mixed and permanent dentition
Compensation High-angle malocclusion Skeletal Dentoalveolar Mixed dentition
2009/1/4
Dentoskeletal morphology was assessed in 191 untreated and unselected children with a hyperdivergent (high-angle) mandibular plane (ML/NSL 40 degrees) by analyzing lateral roentgenographic cephalo...
Mesiodistal Crown Dimensions and Tooth Size Discrepancy of the Permanent Dentition of Dominican Americans
Tooth size Tooth size discrepancy Bolton ratios Dominican Americans

Longitudinal Dental Arch Changes in the Mixed Dentition
Dental arch width Dental arch depth Children Asymmetry
2008/12/19
The purpose of this study was to investigate dental arch changes that occurred during the mixed dentition in 30 normal occlusion children. Two analyses were done. The first one was at the age of e...
Preliminary Investigation of Nonsurgical Treatment of Severe Skeletal Class III Malocclusion in the Permanent Dentition
Nonsurgical treatment Facial profile Soft tissue change
2008/12/19
The purpose of the study was to analyze the effects of nonsurgical treatment on subjects with a severe skeletal Class III deformity and to directly evaluate dental and facial profile changes. Eigh...
