Abstract
|
|
|
Full-mouth reconstruction of a patient using dental implants is a challenge if there is vertical and horizontal bone
resorption, since this includes the gingival area and restricts the position of the implants. however, hard- and soft-tissue
grafting may allow the implants to be placed into the desired position. Although it is possible to regenerate lost tissues,
an alternative is to use fixed detachable prostheses that restore the function and the esthetics of the gingiva and teeth.
Various material combinations including metal/acrylic, metal/ceramic, and zirconia/ceramic have been used for constructing this type of restoration. Other problems include wear, separation or fracture of the resin teeth from the metal/acrylic prosthesis, chipping or fracture of porcelain from the metal/ceramic or zirconia/ceramic prosthesis, and fracture of the framework in some free-end prostheses. With virtually unbreakable, chip-proof, life-like nature, monolithic zirconia frameworks can prospectively replace other framework materials. This clinical report describes the restoration of a patient with complete fixed detachable maxillary and mandibular prostheses made of monolithic zirconia with dental implants. The occluding surfaces were made of monolithic zirconia, to decrease the risk of chipping or fracture. The prostheses were esthetically pleasing, and no clinical complications have been reported after two years.
