Implantation - an artificial tooth root replacement
Advantages of implantation:
Ability to restore the lost tooth without grinding of neighboring teeth. Teeth that are situated nearby will stay alive.
Ability to set fixed prosthesis in the absence of several teeth - implant will serve as a support.
Implants provide an opportunity of prosthesis to fully edentulous jaw with more comfortable fixed structures.
Implants are permanently attached to the bone and provide stable support for artificial teeth. Dentures, bridges and individual crowns that are attached to implants are not loose and does not slip out of the mouth, which is especially important when eating, and during the conversation.
Tight attachment of implants to bone provides a more natural feel than in the presence of traditional bridges or removable dentures. A new artificial tooth feels, functions and looks like a natural healthy tooth.
The stability of dentures on implants is much higher than traditional dentures.
The implant is not only solves the problem of missing teeth, but also removes the extra load from the adjacent teeth, and, consequently, saves them.
It is known that prolonged absence of teeth leads to bone atrophy. Implants allow you to keep the jaw bone: proper load distribution during chewing makes it possible to maintain the level of bone.
Implantological treatment is carried out using such systems as Replace, Antagyr, Impladent, Q implant.
Patients with severe atrophy of the alveolar ridges are rendered with the system of measures (sinus lift, autotransplantation of the bone blocks, soft tissue grafting) in order to carry out the further implantological operation in accordance with the principles of modern dental surgery. The loss of teeth can change the appearance, proportions of face and can lead to the speech distortion.
Removing even a single tooth entails a number of problems due to the displacement of adjacent teeth to the resulting defect that can cause improper closing and the ratio of dentition during chewing, functional overload, and disease of the remaining teeth. This kind of "chain reaction", that resulted in the removal of one tooth can lead to the real risk of losing several teeth.
The defect of dentition must be restored without exposing dissection of the adjacent teeth. And also to avoid the negative impact of removable dentures on the abutment teeth and oral mucosa.
New technologies, that have been developing rapidly in recent years, have provided progress in the field of prosthesis. So, dental implantology is one of the high-tech area in dentistry, that allow to proceed the rational prosthesis without teeth preparation and to avoid a removable prosthesis, even when they are completely lost.
Dental implants - an alternative to removable dentures
This is especially suitable for the patients, who due to the different reasons have difficulties or unacceptable to use the removable dentures. Nowadays, a huge clinical experience of usage of the dental implants is gained, that persuasively proves that teeth implantation - is a reliable and secure way to prosthesis. Implants provide an opportunity to restore a fully edentulous jaws with removable, fixed and conditionally removable constructions.
Dental implantology is a set of surgical techniques aiming at the functional rehabilitation of a patient affected by total or partial edentulism by using dental implants, i.e. metal elements surgically inserted in the bone, or above them but under the gum. These elements are fitted with connectors to fasten them to fixed or removable prostheses, to enable chewing functionality. Such implants can have different shapes, they can be inserted in different positions, with different techniques, then connected to prostheses at different times.
Modern dental implants are made with the usage of space technology by metal processing. During such processing increased the strength of the joint implant with the jaw, that lead to the faster healing and have less traumatic effect. By the way, titanium as a material for implants began to use in 1951. During several conduction of researches, a discovery was founded: in the bone hole, which is prepared atraumatic and exactly correspond to the form of the established titanium construction, occur a strong "connection" of a metal surface with the bone, that is well-known as an process of osseointegration.
Some facts from the history.
In 1959 an italian dentist suggested the construction of the screw implant.
In 1965 is proposed to use a collapsible design of a screw implant consisting of intraosseous parts and to fasten it to the head support (abutment).
In 1969 is invented the implant with the intraosseous part in the form of platten, that allowed to use it in narrow alveolar ridges of jaws. Then were invented hollow implants, with a plasma-coated surface on the intraosseous part, implants in the form of disk, and also implants that are intended for patients with severely atrophied lower jaw. A titanium plasma-spraying method has been used for producing rough implant surfaces. This method consists in injecting titanium powders into a plasma torch at high temperature. The titanium particles are projected on to the surface of the implants where they condense and fuse together, forming a film about 30 nanometres thick. After this, tiny asperities and roughnesses are formed on the surface of the implant. They increase the reliability of fastening - bone tightly "grabs" for them, so that the implant become a part of the jaw.
Types of dental implants procedures
Root form dental implant. This screw type implants is shaped like the root of a tooth. This is the most commonly used implant and is used where there is plenty of width and depth to your jawbone. If your jawbone is too narrow or short for placement of the root form implants, bone grafting may be needed to allow for their placement. After you have received anesthesia, your cosmetic dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take 3 to 6 month for healing. After you have fully healed, your implant is uncovered and an abutment is attached.
Plate form dental implant. If your jawbone is too narrow for bone grafting, a plate form implant is placed into your jawbone. The plate form implant is unique for this purpose as it has a flat and long shape for a better fit into a narrow jawbone. After you have received anesthesia, your implant dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take 3 to 6 month for healing(some plate form implants are immediately ready for restoration without the long healing process).
Subperiosteal dental implants. If there is not enough bone width or height for the root form or plate form implants, the subperiosteal implant is recommended. The subperiosteal implant is custom made to rest on top of your jawbone and under your gums like the plate form implant, but the subperiosteal implant is placed through one of two special methods.
Intramucosal implants. This is another type which is not used very often known as intramucosal implant. It is used to give extra retention and stability to the removable dentures. In this a mushroom shaped attachment is attached on the gum side of the denture and it fits in the indentations which are made from the soft tissues it increases the retention of the removable dentures.
