An extension of a phenomenological model for dental composites

Dental Materials, 1999
The aims of this study are firstly to demonstrate the limitations of a phenomenological model proposed for filler/resin dental composites, and secondly, to modify the model to accommodate these limitations.A power-law rule of mixtures (ROM) is established by a simple modification of the elastic contact mechanics.

A laboratory model for dental radiographic studies

Journal of Oral Rehabilitation, 1995
summary Though a number of laboratory models have been developed to study the effects of X‐ray geometry on the appearance and relative positions of anatomical landmarks, such as the amelocemental junction and alveolar crest, many have failed to take into account the three‐dimensional nature of the alveolus and its spatial relationships with the ...

Interactive Tooth Segmentation of Dental Models

2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005
The accurate segmentation of the teeth from the triangle mesh is an important step in computer-aided orthodontic. Because teeth come in different shapes and their arrangements vary substantially from one individual to another, tooth segmentation is difficult. This paper proposes a new method to accurately segment the teeth interactively.

Videotape Modeling of the Child Dental Patient

Journal of Dental Research, 1976
One week before their first dental visit, 36-to 60-month-old children were shown a videotape to model their behavior in the dental situation. The behavior was then rated for three visits. The children who had been modeled did not behave significantly better than either children who had no previous contact with the dental setting or children who had ...

The Role of Microbiology in Models of Dental Caries

Advances in Dental Research, 1995
Models of dental caries (laboratory, animal, and human in situ models) vary markedly in their microbiological complexity. Laboratory models range from mono-cultures of cariogenic species providing an acidic challenge to enamel, to the development of diverse mixed cultures growing on a habitat-simulating medium in an artificial mouth or chemostat.

Global biomechanical model for dental implants

Journal of Biomechanics, 2011
The osseointegration of titanium dental implants is a complex process and there is a need for systematization of the factors influencing anchoring of implant. A common way of analyzing the strength of the fixation in bone is by measuring the torque required to remove the implants after healing.

Developments in dental plaque pH modelling

Journal of Dentistry, 2005
The objectives of this review were to give a comprehensive account of the methods used to determine dental plaque pH over the last 50 years, to review how these methods have been used in dental cariology research and to give an update as to how dental plaque pH studies might be developed in the future.Published, referred papers and abstracts of ...
