A technique to determine a desired preparation axial inclination

The guidelines recommended in the literature for the convergence angle of a crown preparation vary from 3 to 24 degrees. There is a lack of guidelines on techniques to achieve a specific axial inclination. The purpose of this article was to present a practical technique, with a diamond rotary cutting instrument of known axial inclination, to determine the diamond rotary cutting instrument angulations required to achieve the desired axial inclination of a preparation.

A case report of subpontic osseous hyperplasia in the maxillary arch.

Subpontic osseous hyperplasia has been portrayed in both the historical and the current literature as occurring exclusively in the mandibular posterior region. This article presents the clinical, radiologic, and microscopic documentation of subpontic osseous hyperplasia occurring in the maxillary first molar region.

Water immersion procedure for making light-cured custom trays with wax spacers

This article describes a modified light-curing method that minimizes wax spacer heating and distortion. In addition, this method eliminates the need for tinfoil adaptation or use of a coating to make an air barrier in the fabrication of light-cured custom trays for removable prosthodontics.

The teaching of all-ceramic restorations in Scandinavian dental schools: A survey

The study was designed to survey the curricular requirements, types of clinical experience, and materials/ techniques used in teaching programs for all-ceramic restorations in Scandinavian dental schools. All 13 dental schools responded. Ten offered some clinical experience to pre-doctoral students, but only one required one all-ceramic restoration. The departments of fixed prosthodontics had the main teaching responsibility. All-ceramic crowns were taught at 9, veneers at 7, and inlays/onlays at 10 dental schools. A wide range of different teaching concepts, materials, and views on indications and contraindications was reported. It appears as if all-ceramic restorations are regarded as experimental by the teaching institutions, although the dental industry and some practitioners strongly recommend these types of restorations.
