Zircon CAD / CAM is the newest and most modern method of designing teeth for patients. This latest word in technology brings a perfection in the design of new teeth while increasing the quality of the works.

This latest word of technology eliminates any human error in laboratories and increases the accuracy of the works.

Zircon bridges made of CAD / CAM structures are very efficient and aesthetic in the dental field. Some of its well known characteristics are:

  • it does not interact with other dental materials,
  • it is anti-allergic and 100% biocompatible,
  • it is a good insulator of cold and heat,
  • it is a perfect simulator of natural tooth,
  • and does not change color over time.

 

 

FULL ZIRCONIA is a ceramic material produced in Europe in 2003. It is one of the most contemporary materials, the most aesthetic and the strongest against chewing forces. Full Zircon is the biggest advantage in addition to strength compared to other Zircons, has the property to be produced in different shades as the natural teeth. It is hygienic, does not smell and irritate the gums.

 

Two types of prostheses are removable and fixed.

Fixed prosthesis is done when the prosthesis is attached to natural teeth or implants, while the removable prosthesis rests on the patient’s gingiva which means he can move it.

 

Other innovations are the composition of materials, which come and aesthetically bring a prosthesis more similar to natural teeth and gums (disilicate, zirconia, alumina), or prostheses of a high precision (veneers), which allows to cover the outside of the teeth with a thin ceramic coating.

 

Prosthesis must have the following parameters:

  • Functional: the patient should have good chewing and regular joint functions (opening, closing, left-right laterality, protrusion-retraction, and correct phonetics).
  • Resistance: The prosthesis must resist the chewing forces and be resistant to oral fluids.
  • Non-allergic: The prosthesis should be prepared with materials that do not damage the oral cavity.
  • Aesthetic: The artificial teeth should be as similar as possible to the patient’s natural teeth so as to not effect the profile.

 

 

Fixed Prosthesis

The fixed prosthesis is fixed to the pillar teeth by cementation and cannot be removed by the patient himself.

 

Fixed prostheses include:

  1. Crowns (which can be metal-porcelain, zircon-porcelain, palladium-porcelain, gold-porcelain). Sheaths are prosthesis for single teeth, where the root is stored. Anchored to prepared teeth (stump) or by endocanal screws to root (Richmond crown

 

2. Bridges     (as casings can be made of metal-porcelain, zircon-porcelain, palladium-porcelain, gold-porcelain). In bridges, the tooth that has been removed is replaced by a prosthesis containing the removed tooth and the teeth next to it, which are reduced to the monk being prosthetized. The missing tooth together with the pillar teeth form the bridge.

3. Implant prosthesis: in this case the missing tooth root is replaced with a titanium implant or biocompatible alloy and a fixed prosthesis is cemented on top

Removable Prostheses

Removable prostheses are all prostheses that can replace all or part of the jaw. They are called removable as they can be easily removed and washed by the patient.

Removable prostheses are divided into:

  1. Total prosthesis: The total prosthesis is placed when the patient has no teeth in the oral cavity. It consists of a support structure with acrylic resin and resin teeth, which is held to the patient’s jaw. This prosthesis respects the patient’s profile and chewing functions. It is called total mobile as it can be removed by the patient and washed at any time of the day. To place this type of prosthesis the patient must have a certain amount of bone so that it stays in place naturally.

 

  1. Partial prosthesis: The partial prosthesis is anchored to the remaining teeth with wire braces. It is composed of an acrylic resin structure and resin teeth.

 

  1. Skeletal prosthesis: is a partial prosthesis with a metal support structure.
  2. Skeleton prosthesis with attachment: is a mixed prosthesis which consists of pillar elements such as the teeth that are placed in the casing, a skeletal prosthesis with metal brackets, which make this type of prosthesis to be stable but also for the patient to be able to remove it and set it him/herself at any time of the day.
