After more than 40 years of application, dental implants have become the best restorative solution for missing teeth, and the technology has become very mature with very few failures. As the first choice for restorative dentistry, it has earned the reputation as the “third set of human teeth” due to its perfect performance, strength, biocompatibility and wide range of indications. The effect of implant restoration mainly depends on the patient’s own condition and the clinician’s implant design and technique, and is usually applied to the following cases: (1) single/multiple missing teeth, restoration treatment of missing teeth in the whole mouth. (2) Those who have higher requirements for the cosmetic and chewing functions of the denture. (3)Those who cannot tolerate the poor retention of movable dentures or strong foreign body sensation. (4) Those who choose fixed prosthesis and do not want to wear their real teeth. (5)Those who have severe alveolar resorption or deficiency, poor function of traditional full dentures and poor retention. It should be noted that with the improvement and maturity of modern implant technology, many cases that were previously considered unacceptable for implant restorations can now be completely solved by surgical and restorative techniques, provided that you meet the following conditions: (1) You are 18 years of age or older. (2) No active periodontal disease or other serious oral diseases. (3) Those whose general condition can tolerate minor surgery such as tooth extraction. Can you still recognize the tooth as a denture?
