Indications and contra-indications for dental implant treatment

So, you are thinking about dental implants, but you do not know if they can be placed in you? Below you can familiarize yourself with issues related to indications and contraindications for the placement surgery. Dental implant placement it is a surgical procedure. Depending on the number of dental implants, and also patient’s anatomical conditions, and additional procedures such as, i.e. sinus lift or bone grafting, differs in burden the patient’s organism. It is extremely important to be well prepared for the procedure, considering all “for” and “against”, and inform the oral surgeon on present and past diseases and taken medicines. When we can think about the surgical procedure? These are basically all situations concerning loss of tooth, several or even all teeth.


  • Missing single tooth A single tooth is not so difficult to lose, what presents statistics – almost 100% percent of adult population do not have at least one tooth. It is shocking information. However, statistics is a one thing and the everyday life the other one: with a loss of molar we agree very easy. When the tooth No. 1. is missing, the situation looks quite different. In both cases dental implant will prove to be useful. One tooth can be restored on the implant without the need of grinding the neighbouring teeth. In this situation the implant replaces the one root. Subsequently an abutment is attached on the implant to support the implant crown. This procedure may be done in one day.
  • Missing several teeth Dental implants may replace similarly multiple missing teeth as well as the single missing tooth. Of course it is associated with placement a higher number of implants, but not always one tooth is replaced by the one dental implant. Partial dentures are attached to as so many implants to obtain the stability and chewing force comparable to our natural teeth. It means you will be able chew, eat, bite the same way as when you had your natural teeth. Not only individual missing tooth separated by the remaining tooth/teeth are restored, but also several or multiple missing teeth. Then the partial denture is attached to the implants.
  • Edentulism Edentulism is a condition, when we do not have any own teeth and basically there is no way to fix the denture without adhesives. That alternative is not very comfortable. Patients cannot eat and laugh without fear that the denture suddenly falls out. A tube of adhesive in a pocket is a standard equipment. We do not have to say that it is not a reason to smile…but you can change it! The denture can be stabilised on just a few implants. There are several methods, including one the most practicable solution like the “in Place”.
  • Reasons for missing teeth There are two most common causes of tooth loss: caries and periodontitis. Those are diseases that plague modern societies, and are associated with oversupply of simple sugars in the diet, but also with forgetting about good teeth hygiene. A Little “hole” in tooth it is not a tragedy yet, and we do not have to plan a implantation procedure, but neglected caries may lead to a complete tooth loss, what is more – not only the one tooth! Caries spreads over surrounding teeth, is an infection disease causes by bacteria, therefore daily brushing, flossing, and mouth washing is an obligation. The other reason for teeth loss is injury. Reckless skateboarding may end with a visit at the dentist, and the most exposed are the anterior teeth, because are thinner and less strong than molar teeth. Under control should be cigarettes, that generate a range of adverse changes in the oral cavity leading to teeth loss, promotion of caries, paradontosis, deposition of plaque, not mentioning the significantly increased risk of cancer.
  • Contra-indications As mentioned at the beginning – treatment with dental implants it is a surgical procedure. In the case of missing single tooth it is not related to any particular burden on the organism, and is performed under local anaesthesia. The patient goes home the same day. On the other hand, it is still a surgical intervention into organism, thus there are several contraindications:

General contra-indications (concerning the whole organism):

  • pregnancy 
  • cancer, chemotherapy
  • diabetes (untreated), 
  • osteoporosis
  • rheumatic disease 
  • diseases associated with immune deficiency (AIDS, serious primary deficiencies),
  • blood coagulation disease 
  • caries and paradontitis (untreated)
  • some mental and neurological diseases, 
  • too young age (bone tissue develops until 18-21 year of life)
  • relative contraindication is smoking abuse, which decreases the chance of treatment success, also alcoholism and drug abuse  

Local (depending on the implant site):

  • inadequate bone quality
  • inadequate place to attach the crown or manipulate surgical instruments, malocclusion 
  • site diseases and site tissue damage
Every time a dental surgeon decides about dental implants placement. Very import are the sincere answers to clinician’s questions and in-depth diagnostics, that give the answer whether the bone anatomical conditions are adequate for placement of implant with appropriate parameters. It must be known that some diseases do not completely exclude from dental implant treatment. For example, after oncological treatment when the patient recovers and the disease is inactive, then (after individual examination) there is a chance for a safe and effective procedure. Even diabetes – if is under control and the patient taking medicines - it does not excluded from treatment with titanium dental implants.
