1. What are artificial dental implants? Dental implants, also called artificial dental implants, are not really planted with natural teeth, but through medical means, pure titanium metal with high compatibility with human bone is precisely designed and manufactured into a cylinder or other shape similar to a tooth root, which is surgically implanted into the alveolar bone of the missing tooth area. Because of its non-destructive nature, dental implants have been recognized by the dentistry community as the preferred restoration method for missing teeth. Dental implants are known as the third set of human teeth because they can withstand normal chewing force and are almost identical to natural teeth in terms of function and aesthetics because they are deeply implanted in the bone. 2. What are the conditions for dental implants? (1) The bone of the dental cavity should be of a certain width and height, because generally the artificial implant nail is 10-14 mm long and 3-4.5 mm in diameter. If the bone is not wide and high enough, implantation should be considered after bone grafting. (2) The patient should be in good health and have good oral hygiene. If there is diabetes, heart disease, hypertension, blood disease, etc., the surgery should be postponed. (3) The bone quality of each person is different, some people have too loose bone layer, artificial dental implants can not be closely integrated with the alveolar bone, dental implants are bound to fail. In this case, the patient can only give up the artificial implants and use traditional dentures instead. 3. What are the advantages of dental implants? Compared with traditional dentures, artificial dental implants have many outstanding advantages: (1) its chewing function is much better than other dentures; (2) has a strong retention and stability, like real teeth in the patient’s mouth; (3) can be less or no grinding of their real teeth; (4) does not require the necessary abutments and rings for removable teeth, no large area of abutments lead to dull taste and discomfort; (5) small size (5) small size, no exposed metal, aesthetic, more conducive to maintaining oral hygiene. (6) For some patients who have difficulty or poor results with traditional dentures, oral implants are more superior. In the absence of one or a few teeth, traditional fixed dentures must first grind the two teeth on the edge of the missing area, as a pillar to stabilize the braces, the dentures will be solid, while the movable dentures have to make a large base plate as a base, making people feel uncomfortable and foreign body feeling. In contrast, artificial implants can be placed directly in the missing tooth area to fix the dentures without losing other teeth and without foreign body discomfort. In the case of total absence of the posterior part of the molar area, only movable dentures could be installed in the past. However, the chewing function of movable dentures is poor, and the metal hooks of dentures tend to catch dirt, which is not easy to clean, and the metal hooks also tend to be exposed, affecting the aesthetics. Artificial dental implants do not have these disadvantages. When a full mouth of teeth is missing, a full mouth denture must be made, traditional dentures rely only on the support of the mucous membrane of the dental bed soft tissue, the fixed force is weak, not only the denture is easy to loosen, chewing function is also poor, only 30% or 40% of the normal function can be restored. In addition, if the gums are not properly stressed, the alveolar bone will gradually shrink, and the effect of dentures will become worse and worse. In contrast, artificial dental implants have no movement or poor chewing function, and the alveolar bone at the implant site is functionally stimulated by the dental implants, delaying the resorption of the alveolar bone.
