T he selection of an appropriate occlusal registration strip enables the dentist to work with precision and provides valuable information on occlusion. There are significant differences in the thickness, strength, and plastic deformation of the various articulating papers and occlusal registration strips. The patient’s perception of occlusal thickness ranges from 12.5 to 100 prn.“‘j The thickne...

The management of occlusal caries still remains a major challenge for researchers as well as for general practitioners. The present paper reviews and discusses the most up-to-date knowledge and evidence of the biological principles guiding diagnosis, risk assessment, and management of the caries process on occlusal surfaces. In addition, it considers the whole spectrum of the caries process on ...

Background The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. Objective The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. Material and methods The samp...

OBJECTIVE The purpose of this study was to evaluate the effect of occlusal contact area for loading on the cuspal defection and stress distribution in a first premolar restored with a high elastic modulus restorative material. MATERIALS AND METHODS The Rhinoceros 4.0 software was used for modeling the three-dimensional geometries of dental and periodontal structures and the inlay restoration....

AIMS To establish the minimum dimensions for a non-precious cast metal occlusal rest by using mathematical analysis. An occlusal rest in a removable partial denture (RPD) provides vertical support and allows occlusal forces to be transmitted through the long axis of the abutment tooth. METHODS The stress status of an occlusal rest in a posterior tooth-bounded RPD resembles that of a cantileve...

The pathogenesis of ‘abfraction’ has been considered to be multifactorial with contributions from occlusal loading becoming increasingly prominent in recent years. The objective of this study was to find out whether the presence of an extensive occlusal amalgam restoration and eccentric parafunctional loads would cause increased cuspal movement and therefore, increase in cervical stress exceedi...

OBJECTIVES (1) To evaluate the applicability of using 3D digital models in the assessment of the magnitude of occlusal contacts by measuring occlusal contact surface areas (OCSAs) and 3D mesh points in 'contact' (OCMPs) in a sample of orthodontic patients; (2) To detect any sex differences in the magnitude of occlusal contacts in all malocclusion groups; (3) To detect inter- group differences; ...

With the experimental design of this study the following conclusions were reached. 1. Biting force during maximum clenching was the greatest when the occlusal plane was made parallel to the ala-tragus line. It decreased when the occlusal plane was inclined about 5 degrees anteriorly or about 5 degrees posteriorly. 2. The efficiency of biting force exertion during maximum clenching showed the be...

The diagnosis of occlusion-generated disorders of the dento-maxillary apparatus represents a sensitive stage within the establishment of the therapeutic means for the functional rehabilitation of dental arches. The laborious effort carried out in order to specify the diagnosis resides in the fact that any trauma arising at the level of any component of the stomatognate system may lead to an occ...

INTRODUCTION The influence of occlusal condition at the onset of temporomandibular disorders (TMD) has been strongly debated for many years and still is the source of controversy. Up to the eighties in the last century, the occlusal factors such as the presence of uncured malocclusions, discrepancies between intercuspal position and retruded contact position greater than two millimeters, retrus...
