1. What are dental implants? Dental implants are titanium implants that have been specially indicated to be placed in the jawbone and mechanically connected to the upper dentures (porcelain teeth) to repair missing teeth. Principle: Osseointegration theory, Professor Branmark of Sweden discovered that titanium can be biologically bonded with human bone, called osseointegration theory, which is the biological basis of dental implants. 2. Success rate? The success rate of modern regular dental implants is about 98% in 10 years. 3. Indications? What kind of people cannot have dental implants? People with serious systemic diseases, such as heart attack, uncontrolled diabetes, blood diseases, etc.; minors. Is it possible to have dental implants with insufficient bone mass? Yes, implantation by bone augmentation method will increase the complexity of the surgery, the cost and procedure will increase, and the possibility of failure will be higher. One of the keys to the success of dental implants is to bury the implant in the bone. Therefore, the affected teeth that cannot be retained should be extracted in time to avoid repeated inflammation leading to the resorption of the alveolar bone, thus affecting the amount of bone needed for dental implants. 4. How long can I have dental implants after tooth extraction? It will vary from case to case. Incisors: The bone can be extracted and planted immediately, and incomplete teeth can be planted 1~2 months after extraction. Posterior teeth: It is recommended to plant teeth about 4 months after extraction. If you have special requirements, you can have your teeth implanted immediately after extraction. No matter the front teeth or the back teeth, when there is obvious inflammation, the teeth cannot be extracted and planted immediately.
