They are those which the patient can take out of his mouth and put back in again by himself.
Among them are:
These are partial prosthetics or totally removable ones that are used to improve aesthetics and the chewing function, transitionally used until the definitive prosthetic is made. The removable ones can be immediate or deferred.
The immediate ones are placed during surgery, provided they are indicated. The most common example is when multiple extractions are performed and the patient does not want to be without teeth at any time
The deferred ones are placed after the mucous membranes have healed correctly.
These are carried out when the patient does not have any teeth, being, therefore, mucosupported, lacking any pillars for clamping. The support of the prosthetic is taken starting at some wide bases, which extend over the surface of the mucous membrane in the alveolar processes. They can be uni-maxillary or bi-maxillary; that is, upper, lower or both, if the patient does not have any teeth in either arch. In this type of prosthetic, the achievement of occlusion balance of the upper and lower joints is necessary, taking into account the movements of the jaw, chewing and the stability of the prosthetic.
They are partial prosthetics, dental-muco-supported. That is, they are clamped down on the teeth as well as the mucous membrane, and they are performed when the patient still preserves some of his natural teeth.
They are made by means of a metallic structure (Metallic Base) (which can be from different alloys, noble as well as non noble) that has been melted and is shaped manually from a wax pattern and with the use of PET forms, over the coating models. The teeth and reconstructions of the gums are made of acrylic resin.
