Implantation Indications And Contraindications

The main indications of dental implants include:

  • · the absence of one or several teeth;
  • · the complete absence of all teeth in the jaw;
  • · soreness when using dentures.

Certain bone resorption preventive measures in the absence of the tooth load and functional bone are to be taken. In addition the normally required blood tests, the radiography of both jaws plastic template set inside may be necessary.  It is necessary to measure the overall dimensions and characteristics of the various anatomical structures: the alveolar ridge, the mandibular canal, maxillary sinus, and other entities. In addition, some applications may require:

  • · individual jaw pictures. These determine the thickness of the oral mucosa at the site where the operation is expected to install the implant and define the width of the alveolar portion of the jaw;
  • · the measurement  of oral tissues bio potential, particularly in implants installation and dental prostheses made of different metals.

Contraindications for dental implants is usually determined on the basis of:

  • · information about  the diseases the patient has suffered before,
  • · general examination of the patient,
  • · the data on psychological and emotional state of the patient.

The distinction between absolute and relative contraindications depends on the character of the patient’s diseases. Among the absolute contraindications are the following:

chronic diseases such as diabetes, tuberculosis, rheumatic fever, inflammatory disease of the oral mucosa (stomatitis, etc.). This is due to the fact that with these diseases the patient possess extremely low ability to heal wounds, which is characterized by impaired adaptation of the implant;

diseases of blood (including clotting). Thus during the implantation procedure the patient can suffer from bleeding, which is hard to stop;

skeletal system diseases impairing its restorative powers;

diseases of the nervous system;

cancer (i.e., tumors) under therapy, and for some time afterwards.

The relative contraindications include:

  • · malocclusion and increased abrasion;
  • · periodontal inflammation (periodontitis, both acute and sub-acute forms of it);
  • · impaired oral health in the patient;
  • · precancerous lesions of the oral cavity;
  • · disorders of the temporomandibular joint.
  • · the presence of metallic foreign bodies (implants) in other areas ( screws, plates, pins, wire sutures, artificial metal joints, pacemakers, heart valves, etc.);
  • · bruxism (unconscious constant jaws grinding, especially during sleep);
  • · features in the structure of the jaws, which preclude the introduction of dental implants (bone atrophy, impacted teeth, the proximity of the maxillary sinus, etc.). As a result, the reconstructive surgery on the jaw must first be carried out;
  • · pregnancy and lactation (breast milk feeding) are a temporary relative contraindication;

In addition to these contraindications, constant smoking and alcohol abuse, drinking large amounts of coffee and regular consumption of sweets are the factors to be eliminated as the relative contraindications. See here to find out an expert for implantology and other dental services
