Artificial Teeth for Permanent Implantation
Artificial teeth with a low solubility and with properties similar to natural teeth were produced for implantation tests. The teeth were made from MgAI,O, spine! and Ca,(P0,)2 Whitlockite to achieve low solubility and non-toxic reaction products. The method of manufacture is described. This research was conducted to develop a material with characteristics much like natural dental porcelain whic...
متن کاملSolid Freeform Fabrication of Artificial Human Teeth
In this paper, we describe a solid freeform fabrication procedure for human dental restoration via porcelain slurry micro-extrusion. Based on submicron-sized dental porcelain powder obtained via ball milling process, a porcelain slurry formulation has been developed. The formulation developed allows the porcelain slurry to show a pseudoplastic behavior and moderate viscosity, which permits the ...
متن کاملCritical Analysis of Artificial Teeth for Endodontic Teaching
The purpose of this study was to evaluate the use of artificial teeth for endodontic teaching. A questionnaire was prepared and submitted to 18 professors of Endodontics from different Brazilian universities to evaluate the following features of five cloudy resin artificial teeth: internal and external anatomy; coronal chambers regarding their size, shape and canal path; root canal regarding th...
متن کاملTeaching model for artificial teeth and endodontic apex locators.
Artificial teeth are a useful teaching aid during endodontic education. This article describes the development of a simple and inexpensive model that can be equipped with artificial teeth. It shows that working length determination in artificial root canals using electronic apex locators is possible and that the embedding media has no influence on measurements. The model supports the applicatio...
متن کاملNotches in Animal Teeth: Artificial or Natural/pathological?
Animal teeth with notches at the root are sometimes found in archeological contexts. The notches are often considered to have been artificially engraved and the teeth regarded as artifacts of persona/ adomment. However, one has to differentiate between teeth with engravings at the apex or in the middle of the root, where eut marks are to be seen in the notches (these represent adornment) and th...
