Prosthodontics Fixed

Prosthodontics Fixed


Since 1906 this type of tooth restoration has had a prominent position in dentistry. It has become less acceptable in recent years because of high commercial orientation toward white teeth.

Undeniable advantages:

  1. The longevity of cast gold restorations is greater than any other tooth restoration. Many patients and dentists report 40-50 years of service. Some other types of restorations serve only a few years.
  2. Wear of opposing teeth is minimal with cast gold restorations. Gold alloy wears almost exactly like tooth enamel.
  3. Gold restorations are strong and can be made to fit teeth exactly. When cemented with decay-preventive cement, the restorations resist further decay.

Cast Gold Restorations have only a few disadvantages:

  1. They are not tooth-colored, and most people object to using them in areas of the mouth that would display the metal.
  2. They require somewhat more expertise on the part of the dentist and laboratory.

It is interesting to note that most dentists want cast gold restorations in their own mouths.


Crowns made entirely of ceramic materials are available. There are numerous types and brand names of these crowns.

The Advantages Of Ceramic Crowns Are:

  1. They can be constructed to a highly acceptable esthetic level. Usually, ceramic crowns are the most beautiful crowns in dentistry.
  2. Ceramic crowns do not have a metal undercoping, as do porcelain-fused-to-metal crowns. Therefore, those crowns are biologically compatible and have extremely low allergenicity or toxicity.

The Disadvantages Of Ceramic Crowns Are:

  1. Ceramic crowns are not as strong as metal crowns or porcelain-fused-to-metal crows. If your bite is especially abusive, ceramic crowns may not have adequate strength for you. During service, some all-ceramic crowns break and must be replaced.
  2. Some brands of ceramic crowns can be made into fixed prostheses (bridges), but they may not be as strong as metal or porcelain-fused-to-metal crowns.

If you have a need for an optimum esthetic result or you have allergies to metals used in dentistry, you may want to consider ceramic crowns. If not, porcelain-fused-to-metal crowns or metal crowns are better choices.


These restorations replace a missing tooth structure or missing teeth very well, and they should provide years of service, if the patient observes the following suggestions:

  1. Chewing: Do not chew hard or sticky foods on the restorations for 24 hours from the time they were cemented. The cement must mature for up to 24 hours to have optimum strength.
  2. Sensitivity: Do not worry about mild sensitivity to hot or cold foods. It will disappear gradually over a few weeks. Infrequently, sensitivity last longer than six weeks. Please tell us if this occurs.
  3. Aggressive Chewing: Do not chew ice or other hard objects. Avoid chewing very sticky foods such as “hard tack” candies and caramels because they can remove restorations.
  4. Preventive Procedures: To provide optimum longevity for your restorations and prevent future dental decay and supporting tissue breakdown, please use the following preventive procedures:
    1. Brush and floss your teeth after eating and before bedtime
    2. Swish vigorously for 30 seconds with a fluoride rinse
    3. Use a mechanical toothbrush
    4. Use fluoride gel as you would toothpaste (usually requires a prescription from us.)
    5. Use fluoride gel in provided trays for five minutes per day.
  5. Recalls: Visit us for regular six month examinations. Often, small problems that are developing around the restorations can be found at an early stage and corrected easily, but waiting for a longer time may require redoing the entire restoration. Inadequate return for professional examinations is the most significant reason for restoration failure. We will contact you when it is time for your recall appointment. If that does not occur, please call us.
  6. Problems: If any of the following conditions occur, contact us immediately to avoid further problems:
    1. Movement or looseness in the restoration
    2. Sensitivity to sweet foods
    3. A peculiar taste from the restoration site
    4. Breakage of a piece of material from the restoration
    5. Sensitivity to pressure

We will do our best to provide you with the finest quality of oral restoration available today. However, only your continuing excellent oral hygiene and professional recalls can ensure optimum service longevity.


A temporary plastic restoration will serve you for a short period of time until the final restoration is made by the laboratory. A few comments about this temporary restoration will be helpful to you.


  1. The temporary cement requires about one-half hour to set. Please do not chew during that period-of-time.
  2. Temporary restorations are not strong. They may break or come off occasionally. If so, call us, and we will replace them. If you are where you cannot contact us, go to a pharmacy and get some Fixodent. Replace the temporary on your tooth with some Fixodent holding it in place. This denture adhesive will retain the temporary restoration until you can see us. Please do not leave the temporary restoration out of your mouth, because the teeth will move and the final restoration will not fit.
  3. Certain foods will stick to the temporary restoration. This will not happen with the final restoration.

Color: The color of the plastic temporary does not resemble the color of the final restoration.

Shape, Size: The shape and size of the plastic temporary does not resemble the final restoration.

Tooth Sensitivity: Temporary restorations may leak saliva or food into the tooth. Sensitivity to cold, hot, or sweet is not uncommon. This sensitivity will not be present with your final restoration.
