Each removable prosthesis has its own design, depending on the size and location of the defect. Other very important indications are the anatomical aspects, the number of remaining teeth, the condition of the periodontal and mucous membranes. Compared to fixed prostheses, removable prostheses are less comfortable but when implantation is not possible for a variety of reasons, removable dentures are the only option.
STAGES OF REMOVABLE PROSTHETICS:
Consultation - after the Patient's examination, the doctor listens to the Patient's wishes and expectations, and an individual plan for prosthetic works drawn up.
Prosthetic works - according to the drawn up plan, certain stages are performed during each visit: dental impressions, occlusion fixation, measurement, and giving away prostheses.
Care - after completing the works, the doctor will indicate the peculiarities of care. Usually, it is necessary to visit the prosthodontist every year and make prosthetic adjustments.
These prostheses consist of a metal or thermoplastic material frame, plastic gums, and teeth. The arch supported prosthesis is attached to the supporting teeth with hooks or locks.
The adaptation of these prostheses in the mouth is much better than that of simple plate prostheses, due to the strong fixation elements, thus preventing unwanted movement of the prostheses in the mouth.
Such prostheses are attached to threaded implants. A regular dental prosthesis sticks only to the gums. Such a construction is usually chosen when the Patient does not have any teeth but has enough bone to thread into the implants.
These prostheses have special fixators that engage with the fixators on the implants. Prostheses are made of acrylic with teeth of porcelain - this combination makes teeth look natural.
There are two types of dentures that are fixed on implants: bar-retained and ball-retained dentures.
Bar-retained dentures - consist of a metal bar running along the jaw, fixed on an abutment of two to five implants. The denture is fixed on the bar with the help of clasps.
Ball-retained dentures - every implant in the Patient’s jaw has a socket attached to it, which aligns with each of the balls on the denture.
