Dental implants refer to implants that are implanted into the alveolar bone to act as root, increase the fixation of dentures, and can better restore the oral chewing force, including the lower supporting implant and the upper dental restoration. Dental implants can functionally stimulate the alveolar bone, protect the structure of the alveolar bone and avoid its atrophy. In addition, the dental implant can fix the upper denture through the retention device on the foundation post, which has good retention and stability, which can increase comfort and have good chewing force.
At present, patients with single tooth loss, multiple tooth loss and edentulous patients can theoretically receive implant restoration treatment, but their overall health is poor.
Severe endocrine and metabolic disorders, such as uncontrolled diabetes. Hematological diseases, such as erythrocyte or leukocyte hematopathy, disorders of coagulation mechanism, etc. Cardiovascular disease, can not tolerate surgery.
Long-term use of special drugs that affect the ability of blood coagulation or tissue healing. Severe systemic immune disease. Patients with excessive addiction to tobacco and alcohol, neurological and psychiatric diseases, pregnant patients, and patients limited by local conditions of the oral and maxillofacial regions cannot have dental implants.
However, dental implants will produce some complications, which are generally divided into two categories: biological complications and mechanical complications. Biological complications include surgery-related bleeding, nerve damage, perforation of the maxillary sinus, adjacent tooth damage, and postoperative infection, peri-implantitis, and loss. Mechanical complications mainly include implant and prosthesis-related screws, abutments, implant fracture, and prosthesis damage.
