Adhesive pads are elastic plastic films, which can cling to the jaw and hold for up to three weeks. They are used as relines for prostheses on the jaw to improve their grip.
Before an adhesive pad is pressed onto the denture, it must be cleaned and dried. When in contact with the pine, the film is soft and cuddly.
Before applying to the prosthesis, it is necessary to first stroke out the air bubbles from the adhesive material and cut it to fit. Even during denture cleaning, the adhesive pads need not be removed from the denture.
Adhesive pads do not act like adhesives, but work on the basis of suction. The physical basis for the suction forces are adhesion and cohesion. There is no air left between the jaw and the adhesive pad when the seat is properly seated, so that the forces between the molecules of the saliva, the materials of the adhesive pad and the jaw create bonds that ensure a better grip of the prosthesis on the jaw. In addition, forces also act between the adhesive pad and the prosthesis.
Adhesive pads are among the adhesives. These are also available in powder, cream, stripe or gel form.
In addition to the adhesive pad, all other adhesives perform the same function. Powders, creams, gels or stripes are applied to the prostheses. By altering the properties of the saliva, its consistency is also changed so that the adhesive properties of the prosthesis improve in the interplay of all materials. Without adhesives, it would quickly come to loosen the prosthesis.
Generally, adhesives consist of bio or plastic polymers such as sodium alginate, methylcellulose, carboxymethylcelluloses, copolymers of various monomers, paraffin, vaseline, and others. As additives silica, zinc, titanium oxide, iron oxide pigment or menthol, azurubin or various other substances are used.
Adhesive pads are made specifically of materials such as polybutylene, methacrylate, laurate polypropylene, iron oxide pigment and titanium oxide. Polybutylene, methacrylate and polypropylene Laurat are polymeric plastics that are mixed with additives such as iron oxide and titanium oxide.
Basically, a dental prosthesis is attached to the jaw by suction (adhesion and cohesion). The edge of the prosthesis must be individually adjusted to seal the prosthesis. However, there are several factors that reduce the prosthesis's retention and require additional relining in the form of adhesive pads and other adhesives.
For example, the various tongue and mouth movements may cause the prosthesis to loosen and become depressed. Between upper and lower jaw, there are considerable differences in grip. Thus, the lower contact surface, the movement of the tongue and a reduced suction effect, the prosthesis on the lower jaw loosen faster than the upper jaw. Other factors such as the shape of the jaw, the static design of the prosthesis or the cuddly habits play a role in the maintenance of the denture.
For example, within about 20 years of the prosthesis wearing period, the lower jaw becomes worn out, so that it is scarcely available anymore. So that it does not come that far, regular bone reconstruction work must be done to reconstruct the jaw again. To slow down the degradation of the jaw, a well-placed prosthesis is required. This in turn can only be achieved by relining with adhesives or adhesive pads.
The effect of the adhesives is based on the chemical and physical properties of the ingredients. They contain substances that swell in the saliva and thereby produce a certain tenacity of the mucus. This forms a film on the prosthesis, which increases the adhesion forces.
Normally, the adhesives must be removed daily during the cleaning of the prosthesis and reapplied. However, adhesive pads can remain on the denture during cleaning. An adhesive pad can be used for up to three weeks.
The medical benefit of an adhesive pad is very high, on the premise that a lack of relining of the prosthesis can lead to a complete reduction of the jawbone. With the help of padding relining the wear process can be delayed, which represents a significant health gain for the denture wearer. Furthermore, the costs for the construction of the jaw and the dentures can be significantly reduced.
A relining of the prostheses with adhesive pads also makes sense, because so painful pressure points can be avoided. For example, if the jawbone ridge is edged, it causes greater stress during chewing. It can form painful bruises that lead to long term ulcers. These bruises are predestined for infections and in the worst case malignant degeneration. Relining with adhesive pads can prevent this process. Also, the healing of pressure points is accelerated by the use of adhesives. Since the jawbone is in constant change, the relining of the prosthesis should be padded regularly at a one to two year interval.
Furthermore, a fixed prosthesis also increases the biting force of the dentition. However, the biting force of a full dentition, which is a maximum of 50 kp, can not be achieved. However, it allows up to 5 kp biting force when using an adhesive, which in turn also affects the quality of life. To develop the positive effects, however, the adhesive pad should be applied to the jawbone only after adaptation of the denture. Tags:
