An implant or “artificial tooth root” is fit in for the replacement of one or several missing teeth.

The procedure is carried out in ambulatory conditions, and usually with a local anaesthesia. Anaesthetics and sedatives, as well as antibiotics are used. Facial oedema and bruises may appear after the procedure. It is important to observe a calm regimen and use medicine.

Then the implant placement period follows. It lasts for 2-4 months for the lower jaw and for 4-6 months for the upper jaw. As soon as the implant has fixed on to the bone, its uncovering, as well as prosthetics with a crown can be carried out.

Further on professional oral hygiene has to be carried out and the dentist has to be visited on a regular basis (at least two times per year).

Why choose prosthetics with an implant?

  • Separate teeth are replaced without affecting the teeth that are located alongside.
  • For stability – for supporting non-removable bridge prostheses when removable prostheses serve as an alternative, as well as for stabilisation of removable prostheses.

Before choosing to carry out the implantation, the surgeon evaluates the patient’s dental and oral health, oral hygiene, habits (e.g. bruxism, smoking), jaw bone size and quality, diseases that may affect the recovery or because of which it is impossible to carry out the procedure. The volume of treatment depends on several factors – size of the defect, peculiarities of the patient, morbidity, age etc. Pre-implantology treatment (oral hygiene, periodontologic, prosthetic, orthodontic and surgical treatment) may be required.

One has to be motivated and full of hope, as well as able to cooperate with the surgeon and prosthetist.

The financial investment also has to be taken into account.

Unfortunately the implantation is not always successful. The most common causes of failure and risk factors:

  • insufficient size of the jaw bone for a stable placement of a large enough implant. In this case the bone may be enlarged with biomaterials replacing the bone tissues or by grafting the patient’s bone from another place;
  • there are infected pulpless teeth in the mouth, especially near the implants;
  • the patient suffers from serious chronic diseases (in this case a solution has to be found together with the family physician);
  • smoking;
  • bad oral hygiene;
  • incorrect jaw relations;
  • bruxism (teeth grinding during sleep).

If problems occur because of the implants or prostheses that are based on them, please contact a specialist immediately!
