Software development for the automatic calculation of dental arch relationships on digital models in cleft lip and palate
<b>Background: </b>The assessment of dental arch relationships in the evaluation of surgical outcome in orofacial clefting is essential for quality assurance and optimisation of surgical protocols. Valid, reliable and standardised tools are required for multicentre comparison, evidence-based …

Dentofacial morphology in Turner Syndrome karyotypes
… cast model analysis concerning palatal height, dental arch morphology and dental crown width were performed. Eighteen primary teeth were analysed in polarized light microscopy, scanning electron microscopy, microradiography and X-ray microanalysis were performed. The TS females were divided …

Effects of Unilateral Extraction Treatment on Arch Symmetry and Occlusion
… extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were divided into four treatment groups based on the history of occlusal asymmetry and the treatment plan. DesignCAD3000 software …

Three-dimensional assessment of dentofacial deformity in children with clefts
… was noted in cleft children; the maxillary dental arches of the children with repaired cleft palate were shallow, short and narrow; and the dental arch, deformity and the facial soft tissue deformity were unrelated. Contributions to the field: It has been shown that deviation from normal …

Evaluation of Apical, Coronal and Occlusal Form Diffrences with Conventional Orthodontic Treatment
… (CBCT) can be used to accurately identify dental landmarks in order to detect changes in dental arch forms. Purpose: The objective of this study was to determine how apical, coronal and occlusal arch forms change following orthodontic treatment with fixed appliances and to establish a base …

Sleeping Tongue Posture and Its Relationship to Craniofacial Morphology
… resting tongue posture is an important factor in dental arch development and maintenance as well as airway control. What has yet to be quantitatively measured is the duration of time that a subconscious, resting tongue posture is maintained and whether such posture differs among various …

Prevalence and Rationale of Orthodontic Extractions at Loma Linda University
… as part of orthodontic treatment, were analyzed dentally and skeletally. Patients were then categorized according to the degree of crowding in each dental arch. A one-way ANOVA (Kruskal-Wallis) test and Mann Whitney U with Bonferroni adjustments for post-hoc pair-wise comparisons were used for …

Intra-Oral Three Dimensional Scanning for Assessment of Surgical Outcome in Patients with Unilateral Cleft Lip and Palate
… of care, but they can also be used for research purposes to generate an evidence base for best treatment protocol. Surgical outcome indices can be scored from audit records. The World Health Organisation (WHO) recommends study models to be taken pre-surgery and at 5, 10 and 18 years of age. …

Developing evidence-based decision making for tooth replacement in partially dentate patients
… strategies in adult patients with shortened dental arches, including survival rates of prosthodontic interventions, risk of tooth loss and impact on oral-health related quality of life (OHRQoL); to determine the most appropriate tooth replacement strategies in adult patients with 10 or less …

Maxillary Incisor Crown Form and Crowding in Adolescent Orthodontic Patients
<p>Dental crowding occurs when the mesiodistal tooth crown widths exceed the space available in the dental arch for proper alignment. Previous research dealing with this common orthodontic problem has measured mesiodistal (MD) tooth widths or <em>clinical</em> tooth height-to-width ratios from …

Quantitative Analysis of First- versus Second-Premolar Extraction Effects in Orthodontic Treatment
<p>Malocclusions can involve arch-size tooth-size discrepancies that have to be resolved by premolar extractions. Treatment planning in such cases usually involves removing first (P1) or second premolars (P2). Choosing an extraction pattern is a learned skill that incorporates many diagnostic …
