Removable dentures - Causes, Symptoms and Treatment .MF .
With the loss of even a single tooth loss occurs throughout the dentition.To avoid the negative effects (changes in the temporomandibular joint, a change in the bite, chewing surfaces deformation of dentition and others.) The loss of teeth must be carried out prosthetics (recovery of missing teeth).When there is no little teeth (1-3 teeth), often you can get non-removable prostheses.When dentition defect large (6 or more teeth), resort to a removable prosthesis.
Dentures called removable because they can be removed and worn at all times on their own, without injury to surrounding tissues, teeth and damage to the prosthesis itself.
denture should be considered as a medical device, restoring the integrity of the dentition, his chewing ability, and improve the appearance, as well as preventing further damage to the chewing system.
Before starting prosthetics sure to undergo a thorough examination by a dentist orthopedist.The doctor determines the cause of tooth loss, clinical picture, examines the tooth
Types of dentures
Removable dentures are partial (laminar and clasp) - used in the partial loss of teeth, and full - full loss of teeth.
Partial removable laminar dentures - a medical orthopedic devices, restoring basic functions of dental system (eg, chewing).These prostheses are non-physiological, ie,pressure which occurs during chewing, they are transmitted to the tissues that it does not fit (on the mucous membrane of the mouth), and through it - to the alveolar bone and the body of the jaw, palate.Thereby eventually cause bone atrophy.
They are shown in the following cases:
1. If defects of dentition, which can not be recovered non-removable bridge prostheses in order to normalize the function of mastication;
2. When you delete a large number of teeth simultaneously;
3. In the absence of even a single tooth (aesthetic prosthesis);
4. How splinting (holding that strengthens teeth) prostheses;
5. In severe condition of the person in need of artificial limbs;
6. If an allergic reaction to metal dentures.
Contraindications defined by the presence of prosthetic materials, their properties, somatic condition:
1. allergy to plastic and its components;
2. Diseases of the oral mucosa, if they can not be therapeutically to cure;
3. People with epilepsy, schizophrenia.People, work which is related to a certain profession (lecturer, speaker, singer).
Partial removable laminar dentures consist of: a plastic base, clasps (bent) and standard garniturnaja artificial teeth.
Partial removable laminar dentures with curved clasps
On the basis of the prosthesis associated with a number of unpleasant moments.Covering the hard palate, it is a violation of taste, temperature sensitivity.Often there is a violation of speech, self-cleaning of the oral mucosa, its irritation, sometimes the appearance of the gag reflex.The size of the prosthesis depends on the basis of remaining teeth in the mouth, the hard palate vault severity, extent alveolar atrophy of the jaw, and others. The less retained teeth, the larger will be the basis, and conversely, the more teeth, the smaller basis.
Bent clasp in places adjoining to the natural, own teeth, because of the constant injury may cause their excessive abrasion, inflammation of the gums may occur in this area.
advantage of these prostheses can be considered easy to manufacture and low cost.Disadvantages of the plate denture base have caused dentists all over the world desire to reduce its size (up to a thin bridge), and replace the plastic to the metal.So, most likely, was born arc structure (clasp) prostheses.
Bar prosthesis - a modern and comfortable form of a removable prosthesis.It consists of a die-cast metal frame of the plate base and artificial teeth.The framework includes:
- saddle of the cast frame that bears the plastic base with artificial teeth.
- Fasteners (arc), which provide connection and support saddle-holding members.
- Musculoskeletal holding devices (clasps, attachment, telescopic system).
With Seat vertical and horizontal forces generated during chewing, are transferred to the mucous membrane of prosthetic bed.Saddles number depends on the number of defects (missing teeth).
main advantage of such prosthesis in comparison with the plate - chewing load distribution close to physiological (chewing load is transmitted not only to the gum, bone, but also on the abutment teeth, optimally distributes it between the mucosa and the remaining natural teeth).
In addition, the use of the arc reduces the size of the structure, making it more compact and convenient to use.Doug partially covers the palate or sublingual space, so the speech function is not disrupted, preserved sensitivity, will not have discomfort when eating, adaptation to the prosthesis is faster.
indications for the choice of design partial denture depends on the topography of the dentition defects of its length, the state of the abutment teeth, opposing teeth, bite type, individual features.
By the method of fixation there are several clasp dentures:
• clasp denture with support-retaining clasps.
Clasp prosthesis on the upper jaw with cast clasps
Such a prosthesis is held in the mouth by means of support-retaining clasps.These do not just fix the clasp prosthesis, but also allow to distribute chewing pressure between the mucous membrane prosthetic bed and periodontal (gum, tooth ligament and alveolar bone) of the abutment teeth.Klammer, in contrast to the laminar dentures, cast.They are much more durable and less visible than bent.
• Clasp prosthesis on locks (attachments)
Clasp prosthesis on attachments to the mandible
attachment (castle mount) - more complex attachment, which consists of two parts.The first part secured to the abutment tooth on an artificial crown.It is not mobile and is called the matrix.The second part includes a locking connection matrix.It is rigidly connected to the prosthesis and makes the movement only with him.
element of attachment on the crown abutment
Such attachment reliable and aesthetically pleasing, but it may break.The difficulty of such a tool joint replacement does the limited scope of their application.
• Clasp prosthesis on telescopic crowns
Clasp prosthesis on telescopic crowns
Telescopic crowns are a system consisting of two parts - internal and external.The internal part is a metal cap covering the tooth stump.The outer part is a crown with severe anatomical shape.The inner part (cap) strengthen the tooth cement, outdoor (crown) is connected to the prosthesis.Fixing reliable and aesthetic.Such attachment is shown at low clinical crowns of the abutment teeth, where conventional support-retaining clasps do not provide good fixation of the prosthesis.
A variety of partial denture is a prosthetic Kvadrotti.
This is the same clasp prosthesis.Only his frame and clasp are made of high-quality plastic injection molding bezmonomernoy.The prosthesis has a natural look.It usually has no allergic and toxic effects on the oral mucosa.The material does not absorb oral microflora.Frame kvadrotti lighter metal skeletons.They do not catch the eye, and strong enough, almost like a metal.
frame of the denture can be matched to the color of natural teeth.Because of its flexibility it has elastic memory ability, i.e.It adapts to the anatomic changes in the jaw.
positive properties of prostheses kvadrotti:
• No need to cover the supporting crowns teeth;
• They are very flexible, so seldom break;
• Do not rub the gums, do not change the function of speech;
• Resistant to food dyes;
• Can be used in people with traumatic professions, as well as athletes.
Full removable dentures
Complete dentures are used when complete tooth loss.Full removable prostheses consist of a plastic base (usually made of dental acrylic resins) and of assigned therein artificial teeth.
Full removable dentures
task such prostheses - fill in missing teeth;normalize the function of chewing and speech.Their fixation is carried out at the expense of adhesion (suction effect) and anatomical protrusions jaws.
Modern complete dentures aesthetic and durable.The service life of dentures in an average of 5 years, but this does not mean that after 5 years they will be replaced.If for prostheses look good, periodically adjusting them, their service life can be extended.
Care removable dentures
Dentures should be cleaned as well as the teeth, brush with toothpaste twice a day.And after each meal rinse with running water.
Holders of dentures is not recommended to use viscous and adhesive products.These products may adhere to the prosthesis and can facilitate its breakage.
should be remembered that after the imposition of dentures in the mouth, usually appear pain.This is due to the gradual sedimentation of (pressure) dentures to the mucous membrane.To overcome these feelings is necessary to conduct correction prosthesis.They need more.
first need to spend with your dentist orthopedist the next day after the imposition of the prosthesis, while a visit to his orthopedic prosthesis should be in the mouth for at least 4 hours, even if it is very painful.Otherwise they will not be able to conduct an effective correction.Subsequent correction is necessary to 3-4 over the past two weeks as needed.
Getting used to the removable prosthesis occurs on average within a month, someone maybe more (2-6 months).Terms of adaptation to removable dentures depend on the size and design of the prosthesis, the degree of fixing it on the jaw of the type of nervous system and others. The prostheses get used all the main desire and patience.
Protect removable dentures from mechanical and chemical damage.It is impossible to podshlifovyvat rasp and dentures.When they crack or breakage can not use them, it is necessary to seek medical attention for repair.And do not forget every six months to come to checkups.
