TLDR
It is hoped that this article will aid the reader in understanding the rationale and utility of a simple quantitative tool which could be used in malocclusion assessment. Expand
Maturation of untreated normal occlusions.
TLDR
The dental casts of 65 untreated normal occlusions were evaluated to determine the nature and extent of the developmental maturation process of the normal dentition and changes showed decreases in arch length and intercanine width; minimal overall changes in intermolar width, overjet, and overbite; and increases in incisor irregularity. Expand
An evaluation of changes in mandibular anterior alignment from 10 to 20 years postretention.
TLDR
Cases responded in a diverse unpredictable manner with no apparent predictors of future success when considering pretreatment records or the treated results and crowds continued to increase during the 10- to 20-year postretention phase. Expand
Stability and relapse of mandibular anterior alignment-first premolar extraction cases treated by traditional edgewise orthodontics.
Assessment at least 10 years postretention of sixty-five cases previously treated in the permanent-dentition stage with first-premolar extractions, traditional edgewise mechanics, and retentionExpand
Anterior open-bite malocclusion: a longitudinal 10-year postretention evaluation of orthodontically treated patients.
TLDR
Neither the magnitude of pretreatment open bite, mandibular plane angle, nor any other single parameter of dentofacial form proved to be a reliable predictor of posttreatment stability. Expand
Long-term stability of mandibular incisors following successful treatment of Class II, Division 1, malocclusions.
TLDR
Stepwise backward multiple regression analyses revealed that narrow pretreatment intercanine width and high pretreatment incisor irregularity were significant predictors of relapse. Expand
Long-term changes in arch form after orthodontic treatment and retention.
TLDR
The patient's pretreatment arch form appeared to be the best guide to future arch form stability, but minimizing treatment change was no guarantee of postretention stability. Expand

TLDR
Evaluation of treated premolar extraction cases, treated non-extraction cases with generalized spacing, cases treated by arch enlargement strategies, and untreated normal occlusions demonstrate similar physiological changes. Expand
Dentofacial maturation of untreated normals.
TLDR
Cephalometric head films from a sample of 65 untreated normal persons showed the importance of maxillary development, particularly in the vertical plane, as it was associated with the amount and direction of sagittal mandibular growth. Expand
Postretention assessment of deep overbite correction in Class II Division 2 malocclusion.
TLDR
The results showed that patients with very upright pretreatment maxillary and mandibular incisors tended to have deeper initial overbite and a tendency to return to their original relationship by the postretention stage. Expand
