Using finite element method (FEM), this study sought to investigate how the thickness and Young's modulus of cortical bone influenced stress distribution in bone surrounding a dental implant. The finite element implant-bone model consisted of a titanium abutment, a titanium fixture, a gold alloy retaining screw, cancellous bone, and cortical bone. The results showed that von Mises equivalent st...

Prosthodontic treatment using dental implants is one of the solutions for partially and completely edentulous patients. The peri-implant area is colonized by a large variety of oral microbial complexes. Various prosthesis may provide means of mechanical attachment to the microflora; this in turn allows their aggregation and colonization. There exists a relationship between the peri-implant micr...

Integral abutment bridges (IABs) have many advantages over conventional bridges in terms of strength and maintenance cost. Due to the integrity of these structures uniform thermal and seismic loads are known important ones on the structure performance. Although all bridge design codes consider temperature and earthquake loads separately in their load combinations for conventional bridges, the t...

According to Boucher’s Clinical Dental Terminology periodontal prosthesis is any restorative and replacement device that is used as a therapeutic aid in the treatment of periodontal disease. It is an adjunct to the other forms of periodontal therapy and does not cure periodontal disease by itself. There is always a mounting demand for dental practitioners to integrate periodontal and prosthetic...

An overall treatment with dental implant consist of several essential parts, including a superstructure containing fixture (part of the implant embedding in the bone), abutment (a machined tapered prepared superstructure attached to the fixture), a retainer (which hold the aesthetic portion of the restoration) and the crown (aesthetic part of the restoration). In this common kind of restoration...

Fabricating a crown to retrofit an existing abutment tooth for a partial removable dental prosthesis (PRDP) is one of the most time-consuming and labor-intensive clinical procedures. In particular, when the patient is concerned with esthetic aspects of restoration, the task of fabricating becomes more daunting. Many techniques for the fabrication of all-metallic or metal-ceramic crowns have bee...

Fabricating a surveyed prosthesis beneath an existing partial removable dental prosthesis (PRDP) is a challenging and time-consuming procedure. The computer-aided design/computer-assisted manufacturing (CAD/CAM) technology was applied to fabricate a retrofitted, surveyed zirconia prosthesis to an existing PRDP. CAD/CAM technology enabled precise and easy replication of the contour of the planne...
