A system was proposed to scan dental models record three-dimensional features seen in the anterior teeth create a database of profiles. Dental casts were randomly selected indentations cowhide leather. Reid Bite Reader used measure bite forces generated by Reynolds Controlled Force Generator make impressions. Using Immersion MicroScribe® 3D, information from 53 bitemark depressions and 62 sets ...

The aim of the study was to determine the effect of the flexural strength on denture bases fabricated on different palatal vault depths. Also, to compare the flexural strength of high impact heat cure resin with regular heat cure resin denture bases. Edentulous casts with deep, medium and shallow palatal vault depth were selected. Three different moulds were made in silicone duplicating materia...

It is not known for certain that dental stone components influence titanium welding. In this study, we investigated metallurgical problems caused by laser welding on dental stones using wrought commercial pure (CP) titanium. A pulsed Nd:YAG laser irradiated a number of specimens' surfaces which were fixed on either a dental hard stone or a titanium plate. The metallurgical properties of the wel...

For an implant prosthesis to function permanently and well in the oral cavity, it is necessary to consider various biomechanical factors. 2 Esposito et al. reported that occlusion-induced overloads are associated with increased morbidity and poor durability of dental implants. In order to obtain appropriate occlusal contacts in prostheses, it is important to determine the reproducibility of occ...

PURPOSE In the authors' experience, the color of silicone elastomer following polymerization in molds made of gypsum products is slightly different from the color that was matched in the presence of the patient, before the silicone is packed. It is hypothesized that the investing materials and separating media have an effect on the color during the polymerization process of the silicone. MATE...

The understanding of palatine vault growth in normal subjects is important to orthodontists. The aim of this study was to evaluate three dimensional (3D) longitudinal changes in the palatal vault from 6 to 14 years of age. Complete dental stone casts were biennially prepared for 50 subjects (25 girls and 25 boys) followed up from 6 to 14 years of age. Virtual casts were constructed using 3D las...

OBJECTIVES The aim of the present study was to determine the vertical distance between maxillary central incisors and incisive papilla. METHODS The vertical distance between incisal edges of maxillary central incisors and the centre of the incisive papilla was measured by a digital caliper on the stone casts that were obtained from dentate subjects. RESULTS The mean vertical distance betwee...

This letter discusses the advantages and limitations of the method used in the article “A technique for registration and reorientation of surveyed dental casts” by Majid Abolhasani, Amirhosein Shakibamehr, and Hamid Neshandar Asli for recording and reproducing the cast-surveyor relation.

The use of three-dimensional (3D) analysis of forensic evidence is highlighted in comparison with traditional methods. This three-dimensional analysis is based on the registration of the surface from a bitten object. The authors propose to use Cone Beam Computed Tomography (CBCT), which is used in dental practice, in order to study the surface and interior of bitten objects and dental casts of ...
