- Dentures - removal of defects
Why do we need dentures
Installation instead of lost teeth artificial known since ancient times. The teeth were replaced by wood, ivory and so on. Currently, under the prosthetic means the use of dental prostheses - funds for replacement of defects of dentition. Dentures is part of the orthopedic treatment and preventive means of ensuring normalization functions of chewing and speech and warning further destruction and loss of teeth. Dentures helps eliminate malfunction of the masticatory muscles, temporomandibular joints, and eliminate cosmetic flaws or defects caused by loss of teeth.
Dentures are used to replace the defects of hard tissues of the tooth, dentition, edentulous jaws, the partial or complete substitution of the jaws after maxillofacial operations (for example, by removing a portion of the jaw bone on the tumor or after injury).
Prosthetics must precede the treatment of dental and oral - anything that might interfere with the installation and operation of the prosthesis. Held dental health (treatment of caries

, Oral mucosa, etc.), eliminating the deformation of dentition, excision and scar cords, eliminating short bridles lips and tongue, sharp edges of the alveoli (bone lunes) after the removal of teeth and so on.
Dentures come in a variety of designs, but are divided into two large groups - removable and fixed. The choice of design depends on the size of the prosthesis dentition defect, state of periodontal tissues and prosthetic bed (space, which should take the prosthesis).
Fixed dentures - a prosthesis, which is firmly attached in the mouth, they are permanently without removing. Such prostheses include dental prostheses to replace defects of crowns (inlays, veneers), to replace the destroyed tooth crowns (artificial crowns and polukoronki, Pin teeth), to replace individual teeth or groups of teeth (bridges and dentures console).
Tabs - a prosthesis to replace the defects of the tooth crown. They are often used to seal the tooth and as a support in bridges. Tabs made of different metal alloys, cermets, plastics and so on.
Veneers - transparent thin plate made of porcelain or ceramic metal which is bonded to the front surface of the tooth to alter its shape, color or position.
Artificial tooth crown (metal, porcelain, metal-ceramic, plastic, nylon) or replace damaged natural are the backbone for other types of prostheses. Sometimes these crowns are temporary - they are temporarily protect teeth subjected to special treatment before installing the permanent crown, the manufacture of which takes time. Polukoronki covers three of the four surfaces of the teeth and are used as supports for bridges.
Pin teeth set in the shattered crown, but generally the root of the tooth. To do this, root canal injected metal pin and then set on top of an artificial crown.
Bridges are two supports (adjacent defective natural or artificial teeth) between which the prosthesis is located. Cantilever prostheses, unlike bridges have a support at one end only.
Dentures - Dentures are such that a person can put on and take off on their own. They can be laminar and arc (clasp).
Laminar dentures are used when there are large dental defects and defects that have no bearing on the opposite jaw (ie, on the opposite jaw teeth are missing). Such a prosthesis is composed of a plastic plate (base) which repeats the underlying surface relief of the mucosa and the lateral surfaces of the teeth to which they are applied, artificial teeth, and special devices for fixing prostheses remaining teeth in the mouth (clasps). Quality denture depends on the quality of the materials used in it. Good results are obtained by plastic injection molding method, and prostheses produced from nylon. Nylon dentures differ increased comfort when wearing, do not cause allergies.
Clasp denture - a prosthesis based metal alloy, which in addition to the artificial teeth and the base has an arc and its branches. The basis of the partial denture
Bar prosthesis - the most rational design
It is a metal frame (Arc, clasps, etc.). Clasp prosthesis can be either partial (at replacement of several teeth) and complete (to replace all the teeth. It is more compact, durable and user-friendly than the Plate-.
The denture is made strictly individually. First, the dentist evaluates the condition of the oral cavity and each tooth, making casts of the teeth, and then in the dental laboratory is made dentures. The last step - installation of a dental prosthesis is carried out as a dentist.
