What problems can tooth implantation solve?

• Single tooth missing. In this case there is no need to remove the neighbor teeth nerves and turn-process these neighbor teeth for tooth crown attachment
• A few teeth missing in a row. Tooth implantation provides a possibility to place a stationary dental prosthesis instead of a removable dental prosthesis.
• All teeth missing

Tooth Implantation History

In 1965 professor Ingvar Branemark was a head of research group at the University of Goteborg (Sweden) and his studies finally resulted in osteo-integration discovery (titanium prosthesis integration into tissue). Branemark’s researches were aimed at jaw bone healing and regeneration after injury. The most remarkable thing about this is that osteo-integration phenomenon was discovered accidentally.

Theory

What cases can be solved with the help of dental implantation?
• One tooth missing. In this case there is no need in extracting nerves out of the adjacent teeth and grind them for crowns.
• Several teeth in succession missing. The possibility to make a non-removable construction where earlier a removable denture had to be placed.
• Absolute teeth missing.

How the procedure of implant placement takes place


An implant is basically a screw which is screwed directly into the bone and not into the gum as many patients mistakenly think. A gum is a rather thin area of the mucous tunic which covers the bone only from the outside and it (the gum) cannot serve as an environment for implant placement. And in order to screw an implant into the bone tissue the gum has to be cut and the bone has to be exposed.

After that with the help of special drills and cutters an aperture of a required diameter is formed where an implant is later screwed. The aperture is formed of a definite diameter and depth so that the implant could be screwed into it with some effort and could an implant is screwed and could be safely kept inside the bone without any micro movements.

Into the placed implant a sterile titanium plug (a miniature screw which doesn't allow the bone and the mucous tunic to grow inside the implant and later prevent screwing an abutment to the implant.

The implant with a plug is covered with the gum (which was cut and moved aside at the first stage) and then the gum is sutured. From this moment the implant is considered to be placed and the period of operative wound healing starts. This period takes from 1 to 3 weeks and its length depends on the volume of manipulations performed and the complexity of the operation.

After the end of the healing the doctor the doctor makes up a controlling examination and, if necessary, makes an X-ray image and removes sutures. After those manipulations the patient goes home and waits for the implants to be integrated for usually 2-3 months.
At the end of this period the patient returns to the clinic where the dentist performs a repeated miniature gum incision, finds the integrated implant, screws the plug out of it and places a gum former. The meaning of this operation can be described as follows: we let the implant out into the oral cavity and prepare it for covering with a crown.

As the implant diameter is virtually always less that the tooth diameter (in the place where in goes into the gum) this gum former additionally widens the gum so that the crown would look exactly as if it was a natural tooth. All the process of the gum formation usually takes 1 or 2 weeks. After that with the help of a special clever device a dental model is made and sent to the dental laboratory to make a crown. In the dental laboratory the technician selects and adjusts an abutment for the given implant. An abutment is a definite transition element for the crown anchoring onto the implant. Thus we can see that all the system is kind of a demountable erector set which looks the following way: an implant - an abutment - a crown. It is not by chance, but with the purpose of a quick and comfortable replacement of the crown in some 10-15 years. Imagine the situation that you need to replace the crown on the implant. To do that, the old crown is removed and, if it is necessary, the old abutment is screwed out, and then they are replaced with the new ones. But the implant itself remains untouched and you don't undergo many additional surgical manipulations.
