Implants
The treatment with immediate implants. A fast method for a perfect bite.
It is known for a long time that implants should be planted into the jaw as soon as possible after the loss of one or several teeth. However, dental experts are still debating about after which period the implants should be treated with bridges and crowns and when exactly they can be strained to which extent. In order not to waste away the brain needs permanent challenges and tasks. The case of tissue of bones is similar. A continuous strain is necessary in order to prevent a stunted growth. The stimulation of jawbones is done by means of forces which are passed on by the teeth while chewing the comminution of food. Basically a loss of jawbones always occurs after a loss of teeth. This is prevented by inserting artificial tooth roots.
Thus it is clear that an early restoration with implants after a loss of teeth portrays an important measure against the loss of jawbone substance and prevents long-term damages. The actual structures of the soft tissue and the jawbones remain intact after an immediate implantation. The artificial tooth root is inserted directly into the existing tooth socket directly after the loss or the extraction. After a loss of teeth due to an accident, chronic inflammations or bone and soft part damages an immediate implantation is not recommendable. In this case a sufficient healing period should be scheduled in any case.
Sparing during the healing period?
Until recently the rule applied to dental experts that the implant is not supposed to be strained during an approx. six month healing period if the implantation directly follows after a loss of teeth or an extraction. The risk of the loss of an implant and a prosthetis is significantly higher the shorter the healing period and the higher the strain and pressure on the implant. Exactly these indications are said to have been proven by a large number of studies. Exactly for this reason a provisional solution was inserted into the patient�s mouth during the healing period. This led to a visit at the dentist having to take place at least a second time.
There was only one exception, when three to four implants are connected by means of a bar and can then be strained immediately through a full prosthesis. The term interlock is used in this context. The reason for the immediate strain lied in the assumption that the inserted implants are additionally supported by the tissue surrounding them. The success rate in the case of an immediate strain of implants in the upper jaw just resulted in 50% and now threw doubt on the previous theory.
Is doubt thrown on the previous theory?
First clinical studies meanwhile prove that the previous rule not to strain implants immediately is doubted. Thus it is now tried to deflect forces which impact on the implant by the comminution of food . They should be reduced to such an extent that a certain pressure is not exceeded. By means of new implantation methods and a considerable reinforcement of the torsional moment the primary stability of the implants in bones could be improved. The modified surface of modern implants could also contribute to this. These new measures will permit to immediately equip implants with a fitting, the prosthetics, and to partially strain them immediately.
Of course dentists are also affected by this immediate implant hype through their patients. In order to keep patients soft loading is partially applied. The bar for the connection of several implants is relined with silicone powder. This way the pressure of the prosthesis on the implant can be reduced. But binding studies concerning this method are just running as of recently. Thus no binding statements can be made concerning this technique.
Up to now it can only be bindingly stated that immediate implants are only recommended with very soft food during the first six weeks of the healing phase, thus careful strain. Furthermore it is considered how implants can be protected from relative motions.
The restoration with immediate implants is within our grasp.
However, it is very unlikely that the treated patient can take solid food directly after his treatment. Thus the term immediate implant causes uncertainty and arouses entirely wrong expectations among most patients. It is more adequate not to talk about an immediate strain but about an immediate restoration.
Therefore the number of patients who actually profit from this immediate implantation is still very low. Thus we will still have to be a bit patient with respect to the hope of treating our tooth gaps in one session and subsequently forcefully biting into a steak.
