Excessive occlusal wear can result in pulpal injury, occlusal disharmony, impaired function and aesthetic deformity. Loss of anterior guidance can result from severe wear of anterior teeth, which protects the posterior teeth during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension. This clinical repo...

The management of the interim phase of a complete oral rehabilitation in patients with severely worn dentition is often challenging due to the loss of occlusal vertical dimension, loss of tooth structure, uneven wear of teeth creating an uneven plane of occlusion, and parafunctional habits. This case report describes the management of excessive tooth tissue loss in a 45 year old woman with a hi...

AIM The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. METHODS AND MATERIALS Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusions without crowding or spacing. The second group exhibited Class I m...

The development and reliability of adhesive resin composite systems have offered clinicians a further option for the management of tooth-surface loss. Patients with minimum, moderate, and severe hard tissue wear can be treated based on the application of minimally invasive adhesive composite restorations for posterior and anterior worn dentition. This article presents the "index technique", a n...

STATEMENT OF PROBLEM Treatment of tooth wear is increasing. Because no evidence-based guidelines are available, the clinician may have difficulties deciding which treatment option to choose to resolve complex situations. PURPOSE The purpose of this systematic review was to identify similarities among treatment options for generalized tooth wear and to develop an approach to rehabilitation bas...

Abstract The attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. This clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. The clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements,...

STATEMENT OF PROBLEM No study has evaluated the efficacy of auxiliary tooth preparation elements for crowns with originally reduced resistance form. PURPOSE This study evaluated the effects of different auxiliary preparation features on the resistance form of crowns with reduced axial wall and total occlusal convergence. MATERIAL AND METHODS An Ivorine tooth was prepared on a milling machin...

It is shown that a finite lattice L is isomorphic to the interval between two Hausdorff topologies on some set if and only if L is distributive. The corresponding results had previously been shown in ZFC for intervals between T1 topologies and, assuming the existence of infinitely many measurable cardinals, for intervals between T3 topologies. Mathematics Subject Classifications (1991): Primary...

A 66-year-old man visited our department with the chief complaint of poor esthetics due to loss of a fixed partial denture in a maxillary incisor tooth and difficulty in mastication due to an ill-fitting, mandibular removable partial denture. An analysis of the occlusal vertical dimension resulted in a diagnosis of infraocclusion. After increasing vertical dimension with a provisional restorati...
