ORAL REABILITATION

Removable Prosthesis

It is a metallic, acrylic or flexible structure prosthesis for artificial tooth support intended to restore the functions of chewing, aesthetics and phonetics and can be removed by the patient.

What is the difference between the different types of removable prosthesis?

The skeletal prosthesis is a prosthesis with an individualized metallic base, whose skeleton (structure) can support on the gums and teeth. It has the advantages of being a more resistant prosthesis and of having a better support, preventing its sinking in the gums.

The acrylic prosthesis is built predominantly in acrylic resin, and rests only on the gums, although it may have metal parts preformed for retention (hooks) or nets and bars for reinforcement.

The flexible prosthesis is made of a biocompatible material and, as its name indicates, has the property of being flexible, adjusting to the contours of the mouth while chewing, talking and smiling. It also has the advantages of being light, providing a smoother fitting period, being imperceptible in the mouth as it naturally matches the gums, ensuring colour stability, helping to preserve existing teeth and its biocompatibility makes it ideal for patients allergic to acrylic dentures. It is the removable prosthesis that nowadays offers greater functionality, aesthetics and comfort par excellence.

Will my prostheses need to be replaced?

Over time, the prostheses will need to be readjusted or even replaced, due to the wear and tear caused by their use, and they may start to become wide in the mouth and/or present a significant wear and tear of the teeth. The prostheses start to become unadapted because the mouth naturally changes with age, losing bone and gums.
Misadapted prostheses, which cause constant irritation after a long period of time, can contribute to the appearance of wounds, so you should not use a misadapted prosthesis for a long time.

Periodic consultations are very important to make sure your prostheses remain properly adapted to your mouth and to look for signs of disease.

FIXED PROSTHESIS

It is the partial or total restoration of a tooth crown by means of a prosthesis that is placed on the previously prepared natural tooth and/or on dental implants and cannot be removed by the patient. It can also be used to replace one or more lost teeth.

Fixed dentures on teeth can be crowns or bridges and have the objective of mimicking the natural dentition to the maximum, being the ideal option to increase the longevity of weakened teeth or to rehabilitate lost teeth, not only for comfort but also for aesthetics. 

What is the purpose of crowns?

The crowns are recommended in cases where it is necessary to provide greater resistance and durability to damaged teeth, improve the aesthetics, shape or alignment of teeth in the dental arch.

A crown can also be placed on a dental implant, restoring the shape and structure of the lost natural tooth.

What is the purpose of bridges?

Bridges are recommended to replace one or more missing teeth and are a sequence of crowns, all joined together.
Bridges can be made on natural teeth and in these cases it is necessary that teeth are present at least at the extremes of the dental failure. They can be performed on implants and there is a need to place these implants at the ends of the dental faults.

Do I lose my teeth during treatment?

No. A temporary fixed prosthesis is made suitable for prepared teeth, which will allow you to chew, talk and smile satisfactorily throughout the treatment.

To ensure the longevity of fixed dentures, it is important to have regular check-ups and hygienization.

INDIRECT RESTORATIONS: INLAY, ONLAY AND OVERLAY

Indirect restorations are composite or ceramic restorations made outside the mouth for the rehabilitation of posterior teeth: molars and premolars.

When are indirect restorations indicated?

These restorations are indicated when:
the teeth have extensive cavities with little remaining intact teeth;
for aesthetic reasons, where old restorations are intended to be replaced, since these restorations accurately reconstruct the anatomy, colour and gloss of the tooth;
in posterior teeth with crown fractures that compromise their solidity, since they contribute to a reinforcement of the dental structure 75% higher than so-called “normal” restorations;
in the re-establishment of contact points between adjacent teeth, enhancing the patient’s comfort and avoiding food impact;
in extensive oral restorations, with indication for increases in the vertical dimension of the face.

When is the difference between the various types of indirect restorations?

Indirect restorations can be of three types, according to the size of the tooth surface to be rehabilitated:

  • Inlay – does not involve the restoration of cusps, i.e. the rehabilitation is limited to the “center” of the tooth;
  • Onlay – involves the restoration of the coating of at least one cusp, i.e. the restoration goes somewhat beyond the “center” of the tooth;
  • Overlay – involves the restoration of the entire cusp, i.e. the restoration covers the entire chewing surface.
