By partial denture imply a specific construction used in the absence of several of teeth, but only if full teeth remained on the jaw. Such an orthodontic system makes it possible to restore lost teeth and deal with cosmetic problems. The feasibility of installing a partial denture is determined by the attending physician individually.
All temporary partial removable dental structures consist of the following main components: a single base and soldered fastenings in it, in the form of hooks or micro locks. Modern partial removable denture It has long been used in dentistry, and because of its relatively inexpensive cost, it has gained great popularity.

Partial dentures - types
Based on the indications for use, dentists establish various types of partial removable dental orthodontic structures. The following can be identified main typespopular in modern dentistry.
- Partial denture denture - ideal in the case of obvious defects of the dentition. The use of this design perfectly solves the problem with the restoration of chewing teeth. Such a system consists of special plates with an artificial dental row, which is mounted on the patient's healthy teeth.
- Immediat - it is used as a temporary structure superimposed on the jaw after surgical removal of teeth, and also as a substitute for the main structure for the time of its manufacture.
- Partial removable denture denture - convenient, durable and reliable device compared to similar orthodontic systems used in modern dentistry. In comparison with other structures, the byugel system consists of a special arcuate metal frame, which promotes a uniform distribution of the loads on the jaw.
- Nylon partial denture - used to restore one or more lost teeth.
Main indications and contraindications
In most cases, doctors, dentists are assigned to install a partial removable dental device in the following situations:
- in case of loss of one or several teeth;
- with the complete loss of the upper or lower dentition in the jaw;
- in case of lack of the required number of abutment teeth for the installation of a clasp or bridge system;
- when detecting significant contraindications for the installation of implants in a patient.
Immediately I want to note that removable partial prosthetics has practically no contraindications for use, except for the following cases:
- lack of the minimum number of healthy teeth necessary for installation and reliable fixation, as well as distribution of chewing loads;
- when the patient is allergic to the material used in the manufacture of the orthodontic system.
Although recently there has been a fairly large selection of materials used in their manufacture, so the problem with an allergic reaction in a patient can be removed by selecting a suitable design.
Features of the installation of removable systems
Installation and fixation of the removable structure in the oral cavity in most cases is performed due to clasps or special locks.
- Klammer is a hook attached to the abutment tooth. It is fixed at the very base of a healthy tooth and is absolutely not noticeable during a conversation or when a patient eats food. In the manufacture of clasps use nylon or metal. Thanks to the hooks, the design reliably holds in the mouth.
- The micro lock consists of several parts, one of which is located directly inside the structure, and the other is mounted on the abutment tooth for an artificial crown. This type of fixation is not only aesthetically more attractive, but also more reliable in fastening.
The main stages of manufacturing
On average, the manufacture of a partial removable design, as, in principle, other systems of this kind, will require no more than one month:
- the patient is diagnosed by a doctor, and various diseases detected in the oral cavity are eliminated;
- a specialist takes pictures from the jaw;
- the dental technician produces an individually chosen “spoon” for further use by the attending physician to take the most accurate impression possible;
- wax preparations are made on the basis of the received impressions;
- the design is adjusted to fit;
- after that, the main structure is manufactured in the laboratory;
- The final version of the prosthesis is tried on and transferred to the patient for further use.
Use of combined prostheses
I would like to immediately note that the combined prosthesis is ideal for both partial and full prosthetics. A striking example is the ceramic acrylic denture. This design is comfortable, reliable and not subject to deformation. Wherein to the main advantages of using combined systems Dentures include the following:
- high reliability;
- various fastening methods;
- universality in use;
- a wide range of related elements - various bases and artificial teeth.
I would like to clarify once again that a partial removable denture is not a device that is removed by separate parts. This name of the prosthesis was obtained due to the fact that it is used when replacing parts of lost teeth and is easily removed from the oral cavity.
Partial dentures can made from a variety of materialsbased on the requirements and capabilities of the patient. In this case, special attention in the manufacture of structures of this kind is paid to the attachment of the prosthesis. This is because the quality of locks or hooks determines how reliably the denture will be fixed. in the mouthand therefore patient comfort. In this case, the prosthesis itself consists of three parts - gums from plastic, artificial teeth, and also fastenings.
Main advantages and disadvantages
The advantages of partial prosthetics can include the following nuances:
- possibility of installation without the preparation of teeth located in the neighborhood;
- if necessary, it is possible to install additional teeth;
- ease of care;
- excellent aesthetic characteristics;
- ideal solution for the treatment of edentulous;
- relatively low price.
Naturally, like any other constructions used in dentistry, removable dentures have their drawbacks.
- Insufficiently secure fixation. Often, patients using partial dentures complain about the arbitrary slipping of the latter.
- Atrophy of the alveolar process caused by pressure from a removable denture during chewing.This is due to the direct effect of the prosthesis on the mucous membrane of the alveolar processes. At the same time there is a high risk of atrophy. And in the case of vascular compression, the blood outflow decreases, which contributes to the development of edema of the oral mucosa.
- The emergence of the greenhouse effect. Due to the poor thermal conductivity of the removable denture, there is a temperature difference immediately under and around the prosthesis. At the same time, together with the porosity of the material used in the manufacture of the prosthesis and the accumulation of food residues in it, the formation of the greenhouse effect leads to the appearance of an unpleasant smell from the oral cavity.
Storage and care of a removable denture
Caring for a partial denture is the same as for healthy teeth. is he must be cleaned with a toothbrush using pasta at least 2 times throughout the day.
- After each meal, the denture must be rinsed with water.
- Not recommended to use sticky or viscous food.
- Chewing gum and too hard food (crackers, nuts, etc.) are contraindicated.
Also, the use of the prosthesis may be accompanied by the appearance of pain. This is due to the pressure of the prosthetic design. To eliminate the discomfort you will need removable denture correction.
- The first correction is performed one day after the installation of a permanent prosthesis.
- The next three corrections are carried out within two weeks if the patient feels discomfort while chewing food.
- The process of getting used to partial removable orthodontic systems is quite long. Sometimes it can take up to six months.
At the same time, both the fixation system and the peculiarities of the patient’s nervous system can influence the addiction to a foreign body. However, over time, any person becomes accustomed to wearing and using a partial removable dental device.
Alternative treatment for partial loss of teeth
An alternative procedure for partial dentures is implantationin which even the root of the tooth is restored. Such a prosthesis is considered the most durable, comfortable and aesthetically attractive. At the same time, the installation of implants does not require turning of the teeth located in the neighborhood. However, the cost of such a procedure is much more expensive than removable systems.
Therefore, before giving preference to any variant of dental prosthetics, it is necessary weigh your financial resources and consult with a professional dentist about the use of a particular treatment in a particular case.
