Contraindications to dental implants
Implantation is a relatively not very invasive procedure. Like any surgical procedure, however, it requires a surgical intervention. Therefore, we can distinguish some contraindications to dental implants: relative and absolute, which limit or prevent the implantation procedure.
The most important indications of implant treatment:
- the lack of a single tooth or more teeth,
- edentulism (possibility to abandon traditional dentures),
- interdental problems (implants will be applicable here in order to increase the number of the pillars of the future dental bridge, or a single prosthetic crowns),
- lack of buds of permanent teeth.
Each time before the implantation of the titanium implant our doctors need to check patient’s detailed medical history. Some may not be qualified for implantation due to poor health. But these are extreme cases. Many systemic diseases that are regulated such as diabetes, hypertension, or different types of hormonal imbalance, contrary to popular belief, are not an absolute contraindication to perform dental implant surgery.
General contraindications to dental implants:
- Immune disorders (leukemia),
- Disorders of coagulation (anticoagulants, liver cirrhosis, thrombocytopenia, tendency to hemorrhage),
- Rheumatoid disease (steroid medication),
- Unstable endocrine disorders,
- CChemotherapy (i.e. bisphosphonates) and radiotherapy within the last 5 years,
- Pregnancy and patients under 16 years old (incomplete development of bones).
In addition, during the first visit, any local restrictions for a proposed procedure for dental implant will be defined. Patient who decides to supplement their teeth using implants should heal before all teeth and gums. After conducting a thorough intraoral examination, implantologists in the Perfect Smile Clinic perform 3Dtest with the use of CBCT camera (a computer tomography) to determine the dimensions of the alveolar ridge and the location of important structures as the maxillary sinus and the alveolar nerve canal. Inadequate anatomy of jaw bones is a kind of a local factor which is a relative contraindication. Experienced implantologist is able to assess the degree of surgical intervention, enabling the creation of new conditions for the implantation. Such a procedure is always carefully explained to the patient during the first visit.
Other factors that are contraindication to dental implants:
- Osteopetrosis, fibrous dysplasia;
- Local inflammatory processes;
- Unfavourable anatomical conditions (makroglossia);
- Past radiotherapy;
- Poor hygiene.
