“…The vital information required to diagnose a malocclusion and develop an orthodontic treatment plan consists of models, photographs, panoramic and lateral cephalometric radiographs, and a clinical examination. 1 Digital technology has made significant changes in orthodontics. Digital photography and radiographs are rapidly replacing traditional methods.…”

Objective: To compare the dimensional stability of four impression materials over time and to compare OraMetrix digital models vs traditional plaster models. Materials and Methods: Two traditional alginates (Identic and imprEssix) and two alginate substitutes (Alginot FS and Position PentaQuick) were used to take multiple impressions of a maxillary typodont. Fifteen impressions for each material were taken and poured with plaster at three time points: 72 hours, 120 hours, and 1 week. Five impressions for each material were taken and were sent to OrthoProof for digital model reproduction at 72 hours. Digital models were then integrated with OraMetrix software. Plaster and digital models were measured in the anteriorposterior, transverse, and vertical dimensions. The control typodont and plaster models were measured using a digital caliper, and digital models were measured using OraMetrix software. Results: Statistically significant changes were found for models replicated from Identic impression material in all three dimensions by 72 hours. Statistically significant changes were seen in imprEssix impressions in the vertical and intercanine dimensions. Digital models were significantly smaller in all dimensions compared with plaster models and the control. Conclusions: Identic impression material showed a statistically and clinically significant change in all dimensions within 72 hours and therefore should not be used if impressions are not going to be poured immediately. Alginate substitutes were dimensionally stable over an extended period. Digital models produced by OraMetrix were not clinically acceptable compared with plaster models.

“…Adequacy of clinical examination supplemented by study models for treatment planning procedure of many discrepancies has been confirmed previously (3). The use of algorithms and clinical indicators has been shown to reduce the need of orthodontic radiographs without compromising the treatment goals (13,14).…”

“…It provides linear and angular associations for sagittal and vertical levels of facial bone structures but does not comprise the transversal dimension or function -in other words, the third dimension (1,2). This drawback has led to the questioning of routine prescription and interpretation of LCR regarding its influence on specific malocclusions (3)(4)(5)(6)(7).…”

Influence of Lateral Cephalometric Radiography on Treatment Planning and Preferences in Skeletal Open-Bite Patients: Do Lateral Cephalograms Influence Treatment Planning?

et al. 2017

Objective: To investigate the influence of diagnostic data derived from lateral cephalometric radiographs (LCR) on treatment preferences of specialists planning skeletal open-bite treatment.Methods: Diagnostic records of 25 patients who had been treated at the University of Zurich, Department of Orthodontics, between 1988 and 2007 comprised the study material. Inclusion criteria were 1) skeletal open-bite with no marked antero-posterior discrepancy, 2) dental open-bite, and 3) crowding less than 5 mm. Records consisted of extra-intraoral photographs, panoramic-cephalometric X-rays, casts, and results of analyses. Records, with cephalograms of randomly chosen patients removed, were digitally presented to two orthodontists (A and B), and treatment preferences were asked using Likert-type questionnaires. Three months later, the same records were redelivered with missing cephalograms provided and present cephalograms removed with the questionnaire. Data were evaluated for consistency and tendency to extract using Kappa-κ and McNemar tests. Results:Orthodontist B had no poor-agreement scores, whereas orthodontist A presented very-poor agreement for headgear use. Both A (κ=0.833) and B (κ=0.737) had good to very-good agreement in terms of extraction decisions. Neither orthodontist had any significant tendency for extraction/non-extraction therapy (A=0.99; B=0.5). Conclusion:Information deduced from LCRs had limited influence on treatment planning preferences in skeletal/dental open-bite patients with no marked antero-posterior discrepancy and no influence on extraction/non-extraction decision.

Precision in orthodontic diagnosis can increase the chance of therapeutic success. The objective of this study was to describe the development of a computerized system (prototype), created from a printed table of the Cranial Facial Analysis and Total Dentition Space Analysis with Difficulty Index -Tweed-Merrifield Analysis -in order to aid orthodontic diagnosis. The analysis was transposed from the manual format to the digital format. A user-logical and clear interface was sought for the development of the prototype, consisting of tables and graphs, including automatic, fast and accurate calculations. The result was the immediate visualization of the resolution of the analysis after filling out the fields on the computer. This technological innovation can be a helpful instrument for the orthodontist that favors a more accurate dental-cranial-facial analysis, increases patient safety, orients conduct and may contribute to teaching and research. DESCRIPTORS: Orthodontics; Cephalometry; Medical informatics. RESUMO:A precisão no diagnóstico ortodôntico pode aumentar a chance de êxito terapêutico. Este trabalho teve como objetivo descrever o desenvolvimento de um sistema computadorizado (protótipo), criado a partir de uma tabela impressa da Análise Craniofacial e Análise do Espaço Total com o Índice de Dificuldade -Análise de TweedMerrifield, que visa auxiliar o diagnóstico ortodôntico. Foi aplicada a transposição da análise do formato manual para o digital. Buscou-se uma interface lógica e simples para o desenvolvimento do protótipo, composta por tabelas e gráficos, incluindo a realização de cálculos automáticos rápidos e precisos. O resultado foi a visualização imediata da resolução da análise, após o preenchimento dos campos no computador. Essa inovação tecnológica pode ser um instrumento de auxílio ao ortodontista, favorecendo a obtenção de um diagnóstico dentocraniofacial mais acurado, aumentando a segurança do paciente, orientando a conduta e pode contribuir para o ensino e a pesquisa.
