The Long-term Stability of Class II Cases Treated in a Private Practice Using a Straightwire Appliance: A Dental Cast Analysis
… orthodontist in a private practice setting. Dental casts from a sample of 30 Class II division 1 Caucasian females treated without extractions were evaluated at pretreatment (mean age = 13.1 years), posttreatment (mean age = 15.9 years) and recall (mean age = 28.3 years) to determine the …

3D imaging in forensic odontology
… cannot produce a satisfactory 3D image of a dental cast. At present a laser scanner is required to produce satisfactory results of a dental cast. Angular distortion and errors created by the user in 2D image capture can hinder the digital measurement process. 3D capture therefore introduces …

THREE-DIMENSIONAL FACIAL ANTHROPOMETRY
… fundamental parameters to plan and evaluate dental treatments and maxillofacial surgery, so improving the multi-disciplinary and multi-species studies of genotype–phenotype correlations through simple and precise measurements. In the current study, photogrammetry/stereophotogrammetry systems …

Three-dimensional image analysis for quantification of tooth movements and landmark changes
… analysis methods were developed for digital dental cast models and Cone-Beam Computed Tomography (CBCT) models. A typical analysis procedure includes image reconstruction, landmarks identification, coordinate system setup, superimposition, and displacement or change calculation. The specified …

Die klinische Wirkung der individuellen Mundvorhofplatte auf die Stellung der Frontzähne
In dieser retrospektiven Untersuchung sollte aufgezeigt werden, inwiefern während der Mundvorhofplattentherapie eine erkennbare Stellungsänderung der Frontzähne stattgefunden hatte. Eine Kontrollgruppe sollte Aufschluß geben, ob es sich bei den Veränderungen um wachstumsbedingte physiologische …

Long-Term Changes in the Dental Occlusion of Subjects Treated Orthodontically
… of this study was to quantify the posttreatment dental changes that occurred over approximately a quarter-century in a cohort of women who had received comprehensive orthodontic treatment as teenagers. Dental casts of 52 individuals were made at the start of treatment, at the end of the active …

Influence of Tooth Crown Size on Malocclusion
… industrialized countries. Although the causes of dental malocclusion are obscure in most instances, one contributing factor may be tooth size. While several researchers have studied whether tooth size contributes to malocclusion, there still is no consensus. Some have found that the mesiodistal …

3D tooth surface reconstruction
We describe a method to reconstruct the surface of a tooth given partial information about its 3D shape (e.g., crown or root information). The shape and deformations of a set of specimens representative of the kind of tooth to reconstruct are learnt offline through statistical analysis, leading to …

Mesiodistal Crown Size in Relation to the Risk and Severity of Malocclusion
<p>From among numerous potential causes of dental malocclusion, tooth size has been implicated as one factor. Prior studies show that mesiodistally larger teeth increase the risk of malocclusion. The present report extends our understanding by testing for graded responses between crown size and the …
