The evolutionary success of mammals is rooted in their high metabolic rate. A high metabolic rate is sustainable thanks to efficient food processing and that in turn is facilitated by precise occlusion of the teeth and the acquisition of rhythmic mastication. These major evolutionary innovations characterize most members of the Class Mammalia. Cetaceans are one of the few groups of mammals in w...

Worn, flat occlusal surfaces and anterior edge-to-edge occlusion are ubiquitous among the dentitions of prehistoric humans. The concept of attritional occlusion was proposed in the 1950s as a hypothesis to explain these characteristics. The main aspects of this hypothesis are: 1) the dentitions of ancient populations in heavy-wear environments were continuously and dynamically changing owing to...

OBJECTIVE To evaluate the differences in maxillomandibular transverse measurements at either the crown or the estimated center of resistance (CR), and to compare values between normal occlusion and Class III malocclusion groups. METHODS Dental casts and computed tomography (CT) data from 30 individuals with normal occlusion and 30 with skeletal Class III malocclusions were evaluated. Using th...

Background: Anterior crossbite is a case that when upper anterior are positioned palatally than lower teeth in centric occlusion. Orthodontic appliances using expansion screw could be solution for tooth treatment. Purpose: To figure out the optimal fabrication process of orthodontic single screw. Case analysis: Dental laboratory provided maxillary dental appliance with on 21. technician also re...

The future of dental practice is closely linked to the utilization of computer-based technology, specifically virtual reality, which allows the dental surgeon to simulate true life situations in patients. The virtual articulator has been designed for the exhaustive analysis of static and dynamic occlusion, with the purpose of substituting mechanical articulators and avoiding their errors. These...

There is an increasing population of elderly patients suffering from Alzheimer's disease (AD), the most common form of dementia. In dentistry, a critical problem associated with these patients is the use of a new denture, as AD patients often refuse dental management and are disturbed by minor changes in their oral environment. Some AD patients have further complications associated with oral dy...

Comprehensive soft tissue analysis is an important component of cephalometric analysis. The purpose of this study was to evaluate soft tissue profile of Pakistani adults with Class I occlusion. It was a prospective cross-sectional study, carried out at the Department of Orthodontics, de,Montmorency Institute of Dental Sciences/Punjab Dental Hospital, Lahore. Standardized lateral cephalometric r...

OBJECTIVES To assess the height of occlusal registration blocks made in dental laboratories compared with recommended dimensions. To relate these dimensions to the height of the blocks after registration of the occlusion. METHODS All occlusal registration blocks received in a complete denture clinic at the Charles Clifford Dental Hospital, Sheffield, over a 1-year period were measured in heig...
