The mobile dentures no longer have any support or anchoring element. It sits directly on the gums and jaw bone.
The mobilized (skeletal) denture, on the other hand, sits on the gums and bone, but also relies on the healthy teeth. They need to be consolidated through procedures which have special systems to attach the denture.
A special type of dentures is the one that rests on implants (overdentures). In this case, the additional pressure on implants reduces their life span.
THE ROLE OF DENTURES:
Flexible Partial Dentures are made without a metal structure, from a semi-crystalline thermoplastic material, resistant and durable (Bio-Dentaplast) that fit comfortably in your gums and remainied tooth, having an excellent retention. Its texture allows a thin prostheses (0.3 mm thick incomparable with 2mm thick in case of denture acrylic), eliminating the unpleasant sensation associated with wearing dentures. The material is easy to use thanks to a simple sistem, by injection.
Flexible skeleton prostheses are indicated only after a balanced planning and compliance therapeutic principles laid. The prosthesis should extend as much as possible on the remaining teeth and on the lining of prosthetic field. It has to be determined the direction of the prosthesis insertion, direction that is determined based on the number, situation and position of the shaft of the remaining teeth.
Elastic prostheses can bend and twist without cracking or breaking ow whithout changing it's shape. As time passes the material does not tarnish or it is worn out. Partial flexible prostheses are an ideal alternative allergic to residual monomers patients, this material not being allergic at all, to any situation. Bio-Dentaplast is a semi-crystalline thermoplastic material with a linear structure and high crystallinity. The material shows good physical and chemical properties such as: high hardness, considerable rigidity, strength tensile, very good dimensional stability, limited toxic or allergic potential, resistance at boiling and sterilizing (1500C), resistance to weak acids, alcohols, washing baths, yielding acid pH <4.
The material is opaque colored, this way preventing metal brilliance thru him (or dark surfaces). It is indicated for making dentures bases with hooks, attachments, telescopic works, crowns and bridges, the aesthetic clasps on teeth, by achieving finally a 0.30 mm thickness. The resin is supplied in cartridges, which exclude improper mixing, what has a negative effect on material and on prosthetic restoration. Existing shades are: A2, A3, B2, B3, similar to VITA shades.
Due to the low melting temperature (200 - 2300 C) Biodentaplast Il shows excellent molten material flow, resulting accurate dental works.
