After tooth loss, the traditional restoration method requires the use of the surrounding healthy neighboring teeth to fix the denture, which often inevitably requires some invasive treatment to the neighboring teeth, causing damage to the neighboring teeth. Dental implants are a good way to restore missing teeth without the need to wear out the good neighboring teeth, and the beauty and comfort of the restoration, as well as the good restoration of chewing function, are incomparable to ordinary restorations. So who is suitable for dental implants? 1, the general condition is good, there is a certain economic basis, single or multiple missing teeth, especially the remaining teeth around the missing teeth are not suitable or can make traditional dentures. 2, had worn movable dentures, poor retention, poor chewing function, poor wearing comfort. 3.Severe alveolar resorption when the whole mouth is missing teeth, wearing traditional dentures is not solid, bad function. 4, intolerant to the traditional dental prosthesis. With the continuous development of science and technology, dental implant technology is now very mature and the indications are becoming more and more extensive. In the past, the jawbone that was considered unsuitable for implantation could be successfully implanted after the corresponding technology increased the bone volume. In addition, some systemic diseases such as bleeding disorders, hypertension, heart disease and diabetes can also be implanted after control and stabilization.
