One of the most important steps is accurate impression making for fabrication of fixed partial denture. The two different putty-wash techniques that are commonly used are: (1) Putty-wash one-step technique, (2) putty-wash two-step technique. A uniform wash space is needed for an accurate impression. Nissan et al recommended the use of two-step technique for accurate impression making as there i...

PURPOSE The aim of this study was to measure the changes on the marginal and internal adaptation of zirconia based anterior fixed partial dentures after the porcelain firing process. MATERIALS AND METHODS A total of 34 anterior fixed partial dentures using LAVA CAD/CAM system (3M ESPE, Germany) were applied. Two silicone replicas were obtained: one is obtained before porcelain firing process ...

The most challenging job for a prosthodontist is to rehabilitate the partial edentulous patient especially distal extension cases where fabrication of fixed prosthesis is quite impossible without using implants. Several conventional and contemporary treatment options were available for treating long span edentulous situations. For such cases ,attachment retained cast partial dentures would be t...

The major disadvantage of cement-retained implant-supported fixed partial dentures (FPDs) is difficulty in retrievability. The retentive strengths of the provisional luting agents usually employed in these cases are therefore an important consideration. This study evaluated the cement failure loads of 4 provisional luting agents used for the cementation of FPDs supported by 2 implants or 4 impl...

This article describes a method of making an accurate interocclusal record when the most distal tooth is an abutment of a fixed partial denture. The method uses conical stops, prepared in the enamel of the abutment or made of composite or a metal core covered with composite, to maintain the vertical dimension of occlusion and to act as a third point of reference for a stable occlusal relationsh...

This article provides information regarding the many ways that removable partial dentures (RPDs) may be used to solve restorative problems in the esthetic zone without displaying metal components or conspicuous acrylic resin flanges. The esthetic zone is defined and described, as are methods for recording it. Six dental categories are presented that assist the dentist in choosing a variety of R...

PURPOSE The aim of our study was to explore the effects of different loading positions on the movements of the abutment tooth and denture base of removable partial denture with unilaterally designed framework (RPD-U). MATERIALS AND METHODS The experiment was carried out with a simulation model of a mandible without left molars. The movements of abutment tooth and denture base of the unilatera...

A subpontic osseous hyperplasia (SOH) is a slow-growing, non-neoplastic bone growth that uniquely affects mandibular posterior edentulous ridges underneath pontics of fixed partial dentures. An SOH can result in significant periodontal and restorative complications, however, it is usually corrected by surgical excision. This report presents a series of SOH cases, illustrates SOH management appr...

Partially edentulous patients are frequently restored with implant-supported restorations between and opposing natural teeth. Differences in horizontal and vertical mobility of teeth and dental implants necessitate occlusal contact modification to create prostheses that harmonize with the opposing dentition. This article describes a functionally generated path technique to achieve optimal artic...

The purpose ef this study was to investigate the aecuracy of temporary fixation with Laser welding for fixed partial dentures (FPDs). Five kinds of experimental FPD with different weldinglsoldering gaps were fabricated (O, 20, 501im for welding; 300um for seldering). Then, FPDs were temporary-fixed by laser welding or with a self-curing resin. Fixation accuracy was evaluated by thc changc in di...
