Which elderly people are not suitable for dental implants?

Dental implants have the following absolute contraindications:

1. Newly myocardial infarction.

2. Severe renal dysfunction;

3. After heart valve surgery.

4. Out-of-control endocrine system diseases.

5. Metabolic bone disease or other metabolic or systemic abnormalities of bone.

6. Tumor patients undergoing radiotherapy and chemotherapy.

7. Drug abuse, alcohol abuse or tobacco addiction.

Large drug addicts have low self-esteem, poor disease resistance, a tendency to infection, nutritional disorders, psychological disorders, poor hygiene, etc.

8. You need to take steroids regularly.

This condition is often associated with impaired wound healing, impaired calcium and phosphorus metabolism, and bone marrow dysplasia.

9. Miscellaneous. 1) Long-term immunosuppressants**.

2) Connective tissue disease.

3) Blood diseases (e.g. leukemia, hemophilia).

4) Local malignant tumors and metastases (foci).

5) Severe psychological disorders and mental illness.

If the depression is mild in the early stage, the medication taken does not affect bone metabolism, and it is not necessarily impossible to implant teeth. Dental implants are mainly for the alveolar bone and the health status of the body, there is no limit to age, of course, the ninety-year-old and hundred-year-old man, the food itself is not good, the body has degenerated seriously, and then do dental implants, there is no need, although dental implants are small surgical operations, but there is also a certain trauma.

1. Patients with systemic diseases, such as blood diseases, heart disease, hypertension, diabetes, kidney disease, metabolic disorders, mental illness, etc.;

2. Patients with jaw lesions, such as cysts, osteomyelitis, abscesses, tumors, etc., are not suitable for artificial dental implants;

3. Patients with severe malocclusion, nocturnal bruxism and poor occlusion habits;

4. Osteoporosis caused by periodontal disease, with continuous bone resorption, can lead to loosening and falling off of the implant;

5. The gap between missing teeth is too small, and the distance between teeth is too short;

6. The space between the upper central incisors is not suitable for implantation, which is located in the middle palatal suture, with dense bone and poor blood supply; Moreover, it is easy to injure the vascular nerve when the incisor hole is drilled.

The attachment covers the dental implant, which cleverly combines the attachment denture with the dental implant to re-fix the loose tooth at the same time as the implant, and to maximize the retention of the residual tooth root, so as to achieve no or less tooth extraction. The intervention of attachment technology reduces the number of dental implant roots and eliminates the pain of tooth extraction in the elderly; At the same time, the loose pressure design reduces the weight of the teeth, prolongs the service life of the teeth, and protects the abutments for a long time, which is very suitable for the elderly with complex oral conditions.

1. Systemic contraindications.

1.The elderly and those with poor systemic nutrition should not undergo implant restoration.

2.Patients with metabolic diseases, such as diabetic patients, osteoporosis patients, osteomalacia, degenerative osteitis, etc., should not undergo implant repair.

3.Patients with blood disorders such as leukemia and other bleeding disorders.

4.Patients with collagen diseases, such as pathological immune deficiency and inflammation of collagen tissue, scleroderma, Sjogelin syndrome, rheumatoid arthritis, etc.

5.Implant dentures may become the focus of infection, such as those with a history of bacterial endocarditis, heart and other organ transplant patients should not be implanted.

6.Patients with acute inflammation and infection, such as influenza, tracheitis, gastroenteritis, and urinary tract infection, should not be planted during the period when the infection is not completely controlled.

8.Patients with intellectual disabilities.

9.Patients with neurological and psychiatric disorders. Patients with severe psychological disorders, people with extremely mental and emotional instability.

10.Excessive alcohol addiction and drug addicts.

2. Local contraindications.

1.Patients with pathological changes in alveolar bone, such as local stumps, foreign bodies, granulomas, cysts, and inflammatory reactions, should be implanted after eliminating the above pathological changes.

2.The jaw that has undergone radiation**. Because the bone cells and blood vessels in this jaw have been damaged after radiotherapy, it is easy to lead to implant failure.

3.Patients with oral mucosal lesions, such as leukoplakia, erythema, lichen planus and various types of stomatitis, should not undergo oral implant restoration.

4.Patients with xerostomia syndrome, dry mouth and reduced saliva flow caused by age, autoimmune diseases or long-term medication are not conducive to the self-cleaning of implant dentures and can easily lead to peri-implantitis.

5.Diagnosed with night bruxism Side functional activities such as clenching teeth are not effectively controlled, and the implant is at great risk of traumatic load.

6.People with poor oral hygiene.
