What is a covering denture, their varieties and features, the cost of such a decision, indications and contraindications

Cover denture is a detachable design that covers implants or the available root of the teeth.Cover prosthesis can be made of nylon, plastic or of two materials.

In order to better understand what a covering denture is, it will be advisable to compare it with a removable denture, which everyone knows for certain.

Features and design of

cover prosthesis can be installed on its teeth , and can be applied to implants.Dentists believe that it is better to put them on implants, since this design will last longer.The second advantage is improved fixation, which is important when communicating and eating.When installed on their teeth on them will lie too much load, which can lead to a reduction in the duration of their life.

A complete removable denture can exert a load on the mucosa, which leads to dystrophic processes in the jaw area.Such a disadvantage does not have a cover option.

The best method for installation is "all-on-four".The entire new row of teeth will be installed on 4 implants.Cover dental structures can have many additional devices for more reliable fixation, among them magnetic attachments, elastic retainers, etc.

The main components of the dental prosthesis: telescopic system and root attachments.Attachment has 2 parts: internal and external.It can be fixed in a removable denture, then its replacement is carried out without changes in the system.It is best that the prosthesis has 3 locks, but it has a considerable cost.If the finances are limited, then there will be enough 2 locks.

Depending on the clinical picture and tasks, magnetic clips are installed.Metal hooks clasps fastens the tooth in the neck area.To fix the structure, it can be reinforced with a clasp frame or metal mesh.

The cost of a denture depends on the policy of the dental clinic and the material used.Full acrylics cost from 10 thousand rubles, partial from 7 thousand rubles.The cost of nylon cover designs starts from 25 thousand rubles, if they are complete and from 15 thousand rubles, if partial.Bugelnye can be set at 20 thousand rubles, provided that they are complete and for 13 thousand rubles, if partial.

It is somewhat more difficult to establish "teeth" on implants than on their roots.Therefore, in the first case of a cover prosthesis, the cost will be lower, and in the second case, a number of preparatory works will have to be made, because of which the price will increase.

Advantages and disadvantages of

Overlapping the dentures solves the problem of erosion of hard tissues. Addiction is quick and gentle , pain is reduced to a minimum, because the pressure evenly falls on the roots of the teeth or implants.

It exerts minimal pressure on the mucosa.No need to build up bone tissue.Under the removable design, bone loss does not occur, which is why it will not be necessary to periodically restore and refine the prosthesis.Sensitive people who experience a vomitive reflex do not feel anything during installation and while wearing.

Unfortunately, does not suit all patients with topcoats.Only 10% of patients have indications for their installation.After all, you need to have the roots of the teeth or the soil for the installation of implants.This is more a feature than a disadvantage.

Indications and contraindications

The cover prosthesis is installed in the following cases:

• Presence of single roots on which the functional load will lie;
• with complete absence of teeth, the installation will be carried out on implants;
• with full mandibular adentium( removable in this case will not hold);
• abnormal abrasion of hard tissues;
• fracture or removal of the crown of the tooth.

Do not use cover prostheses, if any:

• diabetes mellitus;
• diseases of the nervous system;
• diseases of the cardiovascular system;
• bleeding disorder.

Installation of prostheses using the "all-on-four" technology

The "all-on-four" technology is the installation of the entire structure for 4 implants.But you need to look at the clinical picture of the oral cavity.On one jaw, you can install either two or four implants.Two of them localize in place of the front teeth, the second or third, the remaining two in place of the sixth or seventh, that is, at the end of the jaw.The front implants are installed straight, the rear implants are placed at an angle of 45 degrees so that an elongated structure can be installed.

Before the beginning of the operation, needs to put in order the teeth and gums of .A complete diagnosis of the organism should be carried out to exclude contraindications.After that, the doctor examines the oral cavity, composes the implant implant scheme and plans further actions.The duration of the operation does not exceed more than a couple of hours.

Waiting for the same installation of the "teeth" on the implants is already more difficult.On the lower jaw it is established after 2 months, on the upper jaw - after 4 months.With the upper jaw, the situation is more complicated, because after implantation the bone must recover.At this time, temporary constructions are put, which will allow a person to feel comfortable in the society.

Constant dentures are made by a dental technician, based on the made casts of .This is done after implantation.
