1 Whichever prosthesis type is indicated, the precision of dental CAD/CAM technology and versatility of full-contour zirconia allow the entire restoration to be milled from a single block of the material, adding to the overall strength. 1 While they are most commonly indicated in fixed prosthesis 1 (FP1) and FP2 cases, in which the prosthetic teeth rise from the gums like natural teeth, they can also be used in FP3 cases, where the monolithic prosthesis includes pink gingival areas in order to reconstitute the soft tissue. Carl Misch’s prosthodontic classifications. This is appealing to many patients and can indicate a fixed solution in cases of limited vertical clearance.Ĭementable monolithic zirconia implant prostheses can be fabricated in various designs as described by Dr. Additionally, the use of custom abutments to support a cementable full-arch bridge allows for low-profile restorations with minimal facial-lingual width. When sufficient hard and soft tissue are present, prostheses can be designed to emerge directly from the gingiva, creating the aesthetics and feel of natural dentition. This allows for the fabrication of restorations ranging from the monolithic zirconia full-arch implant prosthesis-which resembles a screw-retained hybrid denture in form-to cementable prostheses that attach to custom abutments in the manner of traditional crown and bridge work.Ĭementable Option While the screw-retained monolithic zirconia full-arch implant restoration has grown increasingly popular in recent years, the cementable alternative is well suited to many patients. For example, because of its flexural strength of up to 1,465 MPa, BruxZir Solid Zirconia ( Glidewell Laboratories) can be milled into thin layers and can maintain the high level of durability for which the material has become known. Screw-Retained Option Due to the versatility of dental CAD/CAM technology and the material properties of monolithic zirconia, high-strength restorations can be fabricated for the fully edentulous patient in various configurations. By moving beyond acrylic and its vulnerability to wear, chipping, stains, and fracture, this option adds long-term durability to the qualities that make the fixed implant prosthesis the ultimate restorative option for fully edentulous cases. Furthermore, prosthetic materials have advanced in leaps and bounds, and monolithic zirconia can now be milled for fixed full-arch indications. The traditional complete denture, once the standard of care for the fully edentulous patient, is slowly but surely giving way to fixed and removable full-arch implant restorations as their superior stability, function, and aesthetics become more well known. A full arch zirconia implant bridge in Fresno, CA helps prevent undesirable facial changes that can result from bone deterioration.INTRODUCTION Patients facing the loss of their natural dentition have more treatment options than ever before. Unlike traditional bridges, a dental implant zirconia bridge replaces both the tooth roots and crowns, thereby preserving underlying bone and stimulating new growth. A bridge fabricated from zirconia can withstand everyday wear and tear and offers a significantly stronger bite force without fracturing. Its inherent strength enables creating thinner dental crowns than those fabricated with metals. Zirconia bridges eliminate common problems associated with two-material, traditional solutions. Their inner metal layer can cause a visible tell-tale line along the gums and the porcelain coating on the metal can wear, chip or break. Porcelain-fused-to-metal (PFM) crowns are also still used in dentistry, although they have drawbacks. Traditional dentures and some hybrids are made by securing porcelain teeth into an acrylic base, which is essentially a type of plastic. While a zirconia bridge is made from a material with physical properties similar to titanium metal, it offers far prettier aesthetics. A dental implant zirconia bridge in Fresno, CA provides exceptional strength that is comparable to natural teeth.
