All-Zirconia Full-Arch Implant Prosthesis: A Case Study

All-Zirconia Full Arch Implant Prosthesis - Dental CE
Launch Course

Course Objectives (2 CE Credits)

Michael McCracken, DDS, Ph.D.; and Jonathan P. Ouellette, DMD

By maximizing prosthetic stability and function, fixed implant-supported dentures offer significant advantages over traditional removable appliances. Fixed acrylic hybrid dentures have been used to successfully provide edentulous patients with a stable prosthesis for many years now. However, over the long term, acrylic appliances are susceptible to wear, fracture and dislodging of the prosthetic teeth. All-zirconia full-arch implant prostheses improve upon acrylic dentures by offering lifelike esthetics along with superior durability. Constructed from solid zirconia, these full-arch restorations attach to implants through titanium inserts and provide exceptional resistance to wear, chips and cracks. By following a straightforward restorative protocol, clinicians can provide their patients with an edentulous solution that offers maximum stability, durability and esthetics. Topics include:

  • Step-by-step clinical workflow for restoring an edentulous arch with an all-zirconia full-arch implant prosthesis
  • The advantages of monolithic zirconia in full-arch indications
  • The benefits offered by implant-supported prostheses for edentulous patients
  • Indications for multi-unit abutments
  • General parameters for placing implants for implant-supported prostheses
  • Solid zirconia full-arch implant restorations vs. fixed hybrid dentures
  • Use and function of the implant verification jig
  • Procedure for capturing an accurate final impression using an implant verification jig
  • Correcting excessive implant angulation for fixed full-arch restorations
  • Delivery and clinical benefits of fixed full-arch provisionals

Summary

Fixed implant-supported prostheses offer stable restorations for fully edentulous patients while minimizing the bone resorption and soft tissue recession associated with edentulism. Monolithic zirconia full-arch prostheses provide all the benefits of a screw-retained hybrid denture, while greatly improving upon the durability of an acrylic appliance. The clinical protocol for delivering these fixed full-arch restorations is relatively simple, with several steps in place to ensure a precise fit and natural-looking esthetics for the final prosthesis. With the solid zirconia full-arch implant prosthesis, clinicians can dramatically improve the quality of life for their edentulous patients by providing a stable, functional and long-lasting restoration.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
