Teeth, unfortunately, do not have the ability to regenerate, and eventually wear out much. One way to restore the integrity of the dentition is coating the prosthesis. As with any technology, in this method has its advantages and disadvantages, as well as contraindications.
What is coating a removable dental prosthesis?
The subject device is a removable structure, which is firmly fixed by means of special fasteners lock type called atachmen. It consists of three parts:
- basis (base device);
- artificial teeth;
- clasps or clips (holding members).
Mounted for cover dentures on implants or your own teeth, as well as crowns and residual roots. Fixing by means of hooks, magnetic locks, instead of glue like in the case of conventional technologies.
In dentistry, it is preferred coating prosthesis securing implant, usually in the amount of 4 pieces. This is more correct distribution of the load and the pressure on the jaw when chewing. If the prosthesis is fixed to the natural teeth, it can cause them to increased abrasion, wear, damage to the surface of the gums and mucous.
Indications for the installation of devices:
- amputation of the coronal tooth area;
- complete absence or insufficient number of teeth;
- excessive destruction of hard tissue;
- the presence of only the root of the tooth;
- fracture of the crown.
The advantages of this technology is:
- there is a good functional activity;
- It does not need to build extra bone;
- Pressure relief on the palate;
- prevents atrophy of the solid parts of the jaw;
- adaptation process is faster;
- It allows you to restore the tooth row once.
Disadvantages of prosthetics:
- high price;
- need relining (Weld surface on the basis of the additional layer of material to which it is covered to recover to a perfect fit of the prosthesis gum);
- consuming care design.
In addition, there are contraindications to the procedure:
- disorders of the nervous system;
- cardiovascular disease ;
- Pathology of blood clotting.
Coating prosthesis on the upper jaw
Typically, the structure is attached to the upper jaw hook means, instead of on a magnetic lock. This provides a more secure fit, eliminates the risk of loss of the prosthesis.
The device is made in the beginning of the wax in the form of a collapsible working model after receiving a print on silicone filler. Further correction is performed based on artificial teeth and gums forms a curvature of the jaw. Ready prosthesis is covered by a special diamond paste that improves the strength of the structure and reduces the degree of wear.
The coating on the lower jaw prosthesis
You can use this tool is exactly the same as for the upper jaw, but other attachment. Hook lock will be too noticeable to the naked eye, while the magnet will provide a good fixation and a high aesthetic prosthetics.
Due to the increased load on the jaw during chewing process dentists recommend installing the prosthesis on implants (from 2 to 4 pieces). This helps to avoid misuse of the pressure distribution on the roots of natural teeth.
Full coating prosthesis
This type of construction is used in the absence or inexpedient tooth roots residual preservation, for example if they are susceptible to any disease or too fragile. Furthermore, coating the prosthesis in this case can serve as a measure of time maintaining the integrity of the dentition before permanent implantation.
