Prosthodontics

Prosthodontics is the dental specialty primarily concerned with the restoration and replacement of lost or damaged teeth.

Sometimes called the “architects of the smile,” prosthodontists are highly trained specialists with a unique understanding of all the elements that go into a beautiful, functional and natural-looking smile—not just the teeth, but also the gums, lips, and facial features. When it comes to planning and carrying out a full-scale smile makeover, a team of dental professionals is often required; many times, that team is captained by a prosthodontist. What qualifies a prosthodontist to take on this role? After graduating from college and completing the regular four years of dental school, prosthodontists receive an additional three years of advanced training at a graduate program accredited by the American Dental Association (ADA). Prosthodontists combine this specialized education with countless hours of clinical experience, and can bring their skills to bear on simple or complex restorations. They are one of the nine ADA-recognized dental specialties.

Crowns are made to restore the form, function, and appearance of teeth which are badly broken down, worn or fractured.

Although most of the concentration today is on all-ceramic restorations, metal-ceramic restorations, whether they are tooth-supported or implant-supported, are still considered as the gold standard because of their excellent biocompatibility, consistent esthetics, superior strength, and marginal adaptation. Also, metal-ceramic restorations are durable and long-lasting:

  • For the Zirconia-Based Crown and Bridge:

Zirconia frameworks offer new perspectives in metal free fixed partial dentures and single tooth reconstructions because of zirconium’s high flexural strength of more than 900 MPa and showed good first clinical results.

  • For the Zirconia-Based Implant Abutments:

Utilizing zirconia as implant-supported restorations is due to the higher toughness and the lower modulus of elasticity of zirconia. In stabilized and transformation toughened forms, zirconia provides some advantages over alumina in order to solve the problem of alumina brittleness

and the consequent potential failure of implants. These abutments are distinguished by their tooth-matched color, their good tissue compatibility, and their lower plaque accumulation.
