PURPOSE This photoelastic study compared the load transfer characteristics of 2 retention mechanisms in an implant-assisted overdenture prosthesis. MATERIALS AND METHODS Four implants were incorporated into a photoelastic model of a moderately resorbed edentulous human maxilla. Two retention mechanisms were studied by changing components on the same model and the palateless overdenture. The r...

Fabrication of a clinically successful dental prosthesis requires clear and effective communication between dentists technicians. Adequate completion work authorization by provides means for increased professional quality assurance satisfaction in prosthesis. The aim this study was to evaluate the technicians via fixed removable Pakistan. This cross-sectional conducted period 6 months assess A ...

W HEN people lose teeth, the problem of constructing a prosthesis without the aid of natural teeth, and which rests only on the alveolar ridge, must be met. In the maxilla where the surface of the hard palate covered with immovable mucous membrane is utilized for the adhesion and retention of the prosthesis, the problem is lessened because of the increased flat surface area. In the mandible con...

Maxillofacial defects create physical, emotional and mental problems for the patient. The task of surgical-prosthetic rehabilitation is to provide best possible functional esthetic solution. aim this paper was present a modern approach auricular defect rehabilitation. A 24-year-old patient with lack right ear lobe due trauma admited aesthetic Implant-retained prosthesis indicated. Three implant...

Retention of a mandibular denture can be achieved by an implant-retained or natural tooth-retained bar and stud attachment in the anterior segment of the mandible. The same design principles holds true for both implant-retained and tooth-retained methods of anchoring the bar and stud attachment. A simple and cost effective treatment for more complex implant overdenture is the concept of convent...

BACKGROUND For implant-supported hybrid prostheses, high mastication forces and reduced acrylic resin thickness over a metal substructure often cause failures arising from tooth or resin fractures. To assay fracture resistance of artificial teeth and resin in implant-supported hybrid prostheses in relation to the titanium structure and retention design supporting teeth. MATERIAL AND METHODS 4...

dental implants have provided exceptional rehabilitative options for edentulous and partially edentulous patients. however, as more implants come into play, the more the clinicians come across problems where specific considerations must be taken into account to meet expectations. the toronto bridge is a treatment modality proposed for restoring several teeth lost in patients with increased crow...

Retention of implant-supported facial prostheses presents challenges in design that may lead to use of freestanding abutments. This is particularly so in the midface and orbit. Individual implant success rates are lower in these regions, and bone remodeling capacity may be compromised by combined modality cancer therapy. The present study was undertaken to determine the variations in load deliv...
