Dental Implant Placement: Contraindications

Contents:

Due to deep carious lesions and other negative factors, a person can lose one or more teeth or suffer from complete edentulism. Loss of teeth is not only the inability to fully smile but also causes digestion and articulation problems, as well as constant psychological discomfort. Regardless of the number of missing teeth in the dentition, the implant placement procedure helps restore the missing teeth, improve the aesthetic appearance of the smile, regain self-confidence and avoid the typical complications of edentulism.

Despite the whole list of advantages of the implant placement procedure, like any intervention in the body, this technique has contraindications that should not be ignored before choosing this dental restoration method. The generally accepted absolute contraindications for the artificial dental implants placement include:

  • masticatory muscles hypertonia and bruxism;
  • decompensated diabetes mellitus;
  • any types of malignant neoplasms, as well as the metastasis;
  • tuberculosis;
  • severe mental disorders;
  • addiction to drugs and alcohol;
  • connective tissue disorders;
  • all types of autoimmune diseases;
  • functional failure of the liver and kidneys;
  • bone mineralization disorder (osteoporosis);
  • coagulation disorder.

Besides, severe heart and blood vessel disorders and peripheral and central nervous systems disorders can be attributed to absolute contraindications for implant surgery. Many endocrine disorders are also on the list of strict contraindications. This type of dental prosthetics is not performed for people who have undergone chemotherapy, patients with severe immunodeficiency, and organ transplantation since their wound-healing process is disrupted. The implant will not survive.

Taking cytostatic drugs can also provoke the failure of an artificial dental structure. The implantation procedure is performed using general anesthesia or local anesthetics, and therefore, if a person has an individual intolerance to the respective drugs, the implantation cannot be performed.

Recommended Contraindications

In addition to absolute ones, there is a list of relative contraindications that do not exclude the possibility of implant surgery but suggest postponing it for a certain period. These contraindications include:

  • carious lesions;
  • low bone volume, which does not allow the implant placement;
  • tartar;
  • malocclusion;
  • neoplasms in the oral cavity (granulomas, cysts);
  • an inflammatory process in the soft tissues of the oral cavity;
  • periodontitis, periodontal disease, and other gum diseases;
  • tobacco smoking, if a person smokes more than one pack of cigarettes a day;
  • pregnancy and breastfeeding;
  • infectious and inflammatory diseases of a viral, bacterial, or fungal nature;
  • physical fatigue;
  • high risk of facial trauma due to extreme sports.

Dental Implants: Pros and Cons

Any person has the right to choose a particular method of dealing with dental aesthetic problems; therefore, it is recommended to evaluate all the arguments for and against before choosing an implant surgery method. The following statements speak in favor of the implant procedure:

  •  unlike other restoration methods, there is no need to grind adjacent healthy teeth;
  •  it is natural restoration of the dentition, since not only the outer (crown) part is restored, but also the root;
  • the dentition looks more aesthetic and natural;
  • eating solid food is not prohibited;
  • dentures are in the oral cavity all the time; they should not be removed at night;
  • implants do not affect articulation;
  • artificial structures do not put pressure on the mucous membrane, do not cause traumatic damage to the soft tissues of the oral cavity;
  • the service life of such prostheses is more than 20 years.

The following arguments are not in favor of the dental implant procedure:

  1. The probability of artificial structures’ survival rate depends on the individual characteristics of the human body and the patient’s responsibility in oral hygiene quality.
  2. Long recovery period. Implant surgery can be one-stage or performed in several stages, but, in any case, there are limitations at the stage of rehabilitation.
  3. There is a need for surgical intervention.
  4. A highly professional specialist should perform this procedure.

It is necessary to consult a dental implant surgeon to determine the possibility and necessity of performing this procedure. The specialists of the Clinic of Aesthetic Dentistry, located in Kyiv, carry out detailed prosthetic consultations. After consultation and examination, a dental implant procedure of any level of complexity can be performed.

Can dental implants cause cancer?

Any oncological disease, even in remission, is an absolute contraindication for dental implant procedure; but the placement of artificial implants and crowns cannot cause cancer. There is no scientific work or clinically proven information that would give reason to think otherwise. This dentition restoration procedure requires a responsible approach from both the doctor and the patient. In 80% of cases, an artificial tooth root failure occurs due to poor oral hygiene throughout the postoperative period.
