An Implicit Parametric Morphable Dental Model

ACM Transactions on Graphics, 2022
3D Morphable models of the human body capture variations among subjects and are useful in reconstruction and editing applications. Current dental models use an explicit mesh scene representation and model only the teeth, ignoring the gum. In this work, we present the first parametric 3D morphable dental model for both teeth and gum.

Single‐Tooth Modeling for 3D Dental Model [PDF]

International Journal of Biomedical Imaging, 2010
An integrated single‐tooth modeling scheme is proposed for the 3D dental model acquired by optical digitizers. The cores of the modeling scheme are fusion regions extraction, single tooth shape restoration, and single tooth separation. According to the “valley” shape‐like characters of the fusion regions between two adjoining teeth, the regions of the ...

Identification of downstream effectors of retinoic acid specifying the zebrafish pancreas by integrative genomics

Scientific Reports, 2021
Retinoic acid (RA) is a key signal for the specification of the pancreas. Still, the gene regulatory cascade triggered by RA in the endoderm remains poorly characterized.

A mathematical model for the progression of dental caries [PDF]

Mathematical Medicine and Biology, 2013
A model for the progression of dental caries is derived. The analysis starts at the microscopic reaction and diffusion process. The local equations are averaged to derive a set of macroscopic equations. The global system includes features such as anisotropic diffusion and local changes in the geometry due to the enamel melting.

A model for dental workload measurement. [PDF]

American Journal of Public Health, 1982
The primary purpose of the study was to develop a model that would provide an efficient and standardized approach to workload reporting in a non-fee (HMO-like) dental care system. The model was also designed to predict the dental personnel resource requirements in the system as the overall dental needs of the population were already known.

RANKL neutralisation prevents osteoclast activation in a human ameloblastoma-bone model

Journal of Tissue Engineering, 2022
Ameloblastoma is a benign, locally invasive epithelial odontogenic neoplasm of the jaw. Treatment of choice is jaw resection, often resulting in significant morbidity.

Challenges in Dental Statistics: Data and Modelling

Epidemiology, Biostatistics, and Public Health, 2022
The aim of this work is to present the reflections and proposals derived from the first Workshop of the SISMEC STATDENT working group on statistical methods and applications in dentistry, held in Ancona (Italy) on 28th September 2011. STATDENT began as a forum of comparison and discussion for statisticians working in the field of dental research in ...

Comparative Evaluation of Accuracy of Reconstructed 3D Printed Rapid Prototyping Models and Conventional Stone Models with Different Ranges of Crowding: An In-vitro Study [PDF]

Journal of Clinical and Diagnostic Research, 2023
Introduction: The digitalisation of dental models has made significant contribution to the current success of orthodontic practices. Rapid Prototyping (RP) is an innovative method of producing physical objects based on Computer-Aided Design (CAD ...

Comparison of the perception of orthodontists and general clinicians on the use of digital dental models in the city of Aracaju/Sergipe

RGO: Revista Gaúcha de Odontologia, 2023
Context: Digital study models have become a safe and advantageous alternative for diagnosis and planning in dentistry. Despite the superior characteristics in comparison with traditional plaster models, professionals seem to resist the use of new ...
