Systems and Techniques for Removal of Failed Fixed Partial Dentures: A Review
FPDs have a long life span but sometimes they should be removed for several reasons at which they are; secondary caries, the need for root canal treatment, severe gingival recession or periodontal disease, loosened retainer of a bridge, post loosening, root fracture, over contoured and unaesthetic restorations. The removal of temporary crowns and bridges are usually straightforward, while the r...
متن کاملfracture resistance of composite fixed partial dentures reinforced with pre-impregnated and non-impregnated fibers
background and aims. the mechanical properties of fiber-reinforced composite fixed partial dentures (fpds) are affected by fiber impregnation. the aim of this in vitro study was to compare the fracture resistance of composite fixed partial dentures reinforced with pre-impregnated and non-impregnated fibers. materials and methods. groups (n=5) of three-unit fiber-reinforced composite fpds (23 mm...
متن کاملResin-bonded fixed partial dentures: what's new?
BACKGROUND AND OBJECTIVE Dentists often question the use of resin-bonded fixed partial dentures (RBFPDs) for reliable restoration of tooth-bound edentulous spaces. Initial attempts at bonding fixed partial dentures on teeth resulted in early failure due to debonding. In the 1980s and 1990s, improvements in preparation methods, metal alloys and bonding techniques made the RBFPD a more predictabl...
متن کاملFiber-reinforced composites in fixed partial dentures
Fiber-reinforced composite resin (FRC) prostheses offer the advantages of good aesthetics, minimal invasive treatment, and an ability to bond to the abutment teeth, thereby compensating for less-than-optimal abutment tooth retention and resistance form. These prostheses are composed of two types of composite materials: fiber composites to build the framework and hybrid or microfill particulate ...
متن کاملfracture strength and bending of fiber-reinforced composites and metal frameworks in fixed partial dentures
objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...
