INTRODUCTION: Recent researches have shown that, in principle, computer-assisted design, computer-assisted manufacture and rapid prototype technologies (CAD/CAM/RP) can be successfully applied to the fabrication of removable partial denture (RPD) alloy frameworks and replace laboratory crafting techniques. The CAD/CAM techniques have been widely used for a long time to manufacture dental prosth...

Even before considering their introduction into the mouth, choice of materials for optimization prosthesis depends on specific parameters such as biocompatibility, solidity, resistance, and longevity. In first part this two-part review, we approach various mechanical characteristics that affect choice, which are closely related to manufacturing process. Among currently available, it is mainly p...

The early computer-aided design/computer-aided manufacturing (CAD/CAM) systems were relied exclusively on subtractive methods. In recent years, additive methods by employing rapid prototyping (RP) have progressed rapidly in various fields of dentistry as they have the potential to overcome known drawbacks of subtractive techniques such as fit problems. RP techniques have been exploited to build...

the main goal of this study was to evaluate differences in stress distribution relevant to the number of implants under an anterior bridge when combined with a removable partial denture in the posterior region.four three-dimensional finite element models (3d fem) were designed from a mandible containing an implant-supported bridge extending between canines, and a bilateral distal extension remo...

T he growing acceptance of dental implants during the past several years has expanded the treatment alternatives that can he offered to patients. The benefits of implant-borne prostheses are readily apparent for the fully edentulous patient and have been well documented.‘b2 Restoring the partially edentulous patient, where implants and natural teeth coexist, presents many clinical challenges an...

PATIENT This report describes the case of a 68 year old female patient who presented with the chief complaint of difficulty in chewing and poor aesthetics due to missing teeth. The patient was interested in saving the remaining natural teeth and desired minimal tissue coverage from the prosthesis. After consideration of all the factors involved, it was deemed advisable to resort to a palate fre...

Sudden tooth loss in the esthetic zone of the maxillary or mandibular anterior region can be due to trauma, periodontal disease, or endodontic failure. The treatment options for replacing the missing tooth can vary between removable prosthesis, tooth-supported prosthesis, and implant-supported prosthesis. Irrespective of the final treatment, the first line of management would be to provisionall...

AIM The purpose of this case report was to describe the oral rehabilitation of a 4-year-old girl presenting early childhood caries (ECC). BACKGROUND ECC is highly prevalent in developing countries and its severity increases with age. This disease implies serious consequences for the development of the stomatognathic system and for the child's quality of life. As young children are usually anx...

in this paper we define the removable cycle that, if $im$ is a class of graphs, $gin im$, the cycle $c$ in $g$ is called removable if $g-e(c)in im$. the removable cycles in eulerian graphs have been studied. we characterize eulerian graphs which contain two edge-disjoint removable cycles, and the necessary and sufficient conditions for eulerian graph to have removable cycles h...
