The advantages of implants are that they are aesthetically pleasing and comfortable, they maximize the restoration of normal bite function, and they do not damage neighboring normal teeth. The disadvantages are that they are more expensive and have a longer treatment period (usually 3-4 months). Simple oral implant surgery is less traumatic, painless, and the single implant implantation process only takes about 30 minutes; if the bone is seriously insufficient, it is necessary to increase the amount of bone through surgery (e.g. onlay bone grafting, alveolar ridge distraction into the bone, etc., and oral implant restoration is carried out about 6 months after the operation), and the surgical area will have different degrees of swelling and pain in the postoperative period of 3 to 5 days. Advantages of traditional restorative means (movable denture and fixed denture restoration): relatively inexpensive, short treatment cycle; disadvantages: the need to grind the remaining normal teeth and dental tissues, the bite force needs to be borne by the neighboring normal teeth, which will have an adverse effect on them; movable denture comfort and retention of the poor. There is no perfect treatment in the world, only the most suitable treatment for individuals. Therefore, it is important to choose the most suitable treatment for you according to your financial condition, physical condition and subjective factors.
