Contraindications for Implants

Contraindications for implants

Implants are a modern way to restore a lost tooth. Implantation is an operation and therefore, like any surgery, they have contraindications. Let’s talk about them in more detail.

Indications for Implants

A titanium implant is an artificial root that is firmly anchored in the bone.

In the case of one-stage implantation, a crown is immediately placed on the implant, but in case of delayed implantation, the crown is placed 4-6 months later. After that, all the functions of the lost tooth are restored and the patient returns to normal life.

Implants are the most comfortable method of restoring teeth, including those that have been lost completely. Implant-supported restorations last a long time and look natural.

Contraindications for dental implants

Classical dental implantation proceeds in two phases and involves damage to the integrity of the body’s bone tissue, so there are contraindications to its application.

These can be divided into two groups:

Absolute – diseases in the presence of which implantation is not possible in principle

Relative – these are temporary patient conditions that prohibit the operation and diseases that require special monitoring by the doctor.

The list of contraindications to implantation is becoming shorter every year.

Absolute contraindications to implants

Experts have a list of medical conditions that make implants impossible to insert. This list can be divided into three groups:

  • Autoimmune diseases: Lupus erythematosus, rheumatoid arthritis, and multiple sclerosis
  • Tissue regeneration disorders: AIDS, conditions after chemotherapy, some hormonal diseases and organ transplants, connective tissue diseases
  • Serious cardiovascular, nervous (both central and peripheral), endocrine (decompensated diabetes mellitus, chronic liver or kidney failure), or circulatory system disorders, including coagulation disorders.

Other contraindications to implantation are chronic alcoholism and drug addiction, allergic reactions to anesthesia, without which dental implants cannot be performed, and taking medication that increases the risk of rejection of the implant.

If there are absolute contraindications, dental implants cannot be performed.

In this case, the doctor will suggest other ways to restore the teeth.

Relative contraindications to implantation

Temporary contraindications do allow for dental implants, but only if certain conditions are met.

The relative contraindications include:

  • insufficient bone volume
  • bite problems
  • inflammatory processes in the oral cavity
  • Caries
  • compensated diabetes mellitus
  • periodontal disease
  • poor oral hygiene
  • Tartar
  • pregnancy and breastfeeding
  • smoking

Most of these contraindications can be corrected. For instance, bone augmentation, overbite correction with braces, or removal of hard dental deposits with professional oral hygiene. Increased monitoring by the maxillofacial surgeon is necessary in the case of certain diseases, for instance, compensated diabetes.

Hepatitis in remission is not a contraindication for implants. However, surgery must not be performed in the acute phase of the disease.

Age as a contraindication for implants

Age is also a contraindication for the placement of dental implants. The surgery can be done only after the jaw structure and bone structure have fully developed. It is usually done by the age of 18-21 years. There is no clear upper age limit for implants: it all depends on the general condition of the patient.

Possible complications after implantation

Complications after dental implants are very rare nowadays because the technology is well-mastered. However, unpleasant consequences are possible. These usually occur within the first few months after surgery, but in some cases, they can occur as late as 2-3 years.

It is normal, however, if, after the implantation, the following symptoms are observed

  • Pain in the first 2-3 days
  • Edema, which must disappear completely after five to seven days
  • Slight bleeding in the first few days
  • increase in body temperature up to 37°C for three days
  • numbness that should go away after five hours

In other situations, it is necessary to seek immediate medical attention in order to rule out the possibility of complications. The most serious of these is peri-implantitis and implant rejection.
