Contraindications to the placement of dental implants are divided into absolute and relative. Absolute contraindications in implantology mean the impossibility of setup of dental implants. These include acute inflammatory processes, benign or malignant processes in the maxillofacial area.
Relative contraindications mean that the placement of dental implants is impossible until the elimination of a certain risk factor. Relative contraindications in implantology include uncontrolled diabetes mellitus, osteoporosis, osteopenia, metabolic disorders of bone tissue, a period of 6 months after the onset of myocardial infarction or stroke, a period of 12 months after irradiation of the maxillofacial zone due to malignant tumors, the use of bisphosphonates in high therapeutic dosages for the treatment of metastasis in oncology.
If bisphosphonates are used to treat osteoporosis in low dosages, this is not a contraindication for dental implantation.
