By chewing food, human teeth not only participate in the body’s digestive function, but also make human beings experience the pleasure of eating; at the same time, bright teeth play an important role in the face and expression, and can enhance people’s confidence in social life. However, we can lose some or all of our teeth for various reasons, and now there are only three types of restorations: removable denture, fixed denture, and implant denture, which, as the name implies, can be removed, have rings and abutments, and require other teeth and mucous membranes of the mouth to support and fix the denture and perform its functions. The fixed denture relies on other stable and healthy teeth in the mouth to support and perform the chewing function, its aesthetic effect and comfort are better, but it needs to adjust the grinding of our healthy teeth, and at the same time increases the burden of healthy abutment teeth, and is more troublesome to remove after problems arise; while the implant denture is made of artificial materials and implanted into the jawbone through alveolar surgery, which acts as a tooth root. After a period of time (2-6 months), the implant becomes osseointegrated with the surrounding bone tissue, and then an artificial crown is installed on top of the implant root for support to restore the missing tooth, aesthetics and chewing function. Compared with traditional restorations, implant prostheses have incomparable advantages: they are closest to the appearance of natural teeth; they help prevent the resorption of alveolar bone and atrophy of the alveolar mucosa; they do not require fixed bridges to grind down the normal teeth around the missing teeth; they do not increase the burden on the natural teeth due to retention requirements, avoiding damage to the good teeth caused by overburdening; they do not have wire retainers and abutments (or significantly reduced abutments), avoiding foreign body sensation and discomfort. The implant will avoid foreign body sensation and discomfort as well as eating disorders. In the past, we often doubted whether our implants would be rejected by the human body, in fact, this worry has been clinically proven to be completely unnecessary, the material of the implant is mainly titanium, which has good wear resistance, good corrosion resistance, low modulus of elasticity and similar to bone: good biocompatibility, non-toxic and non-side effects, non-magnetic, non-irritating, stable in the body; good wettability, not easy to attach organic materials. Titanium is widely used in medical treatment for artificial bones and joints, heart valves, cardiac pacemakers, etc., in addition to implants. Some patients feel that implant surgery is scary, but in fact, the development of medicine nowadays has made implant surgery a very simple and safe procedure. Most of our regional implants can be almost minimally invasive, no stitches, no stitch removal, and no need for second-stage surgery, and patients basically feel no pain. Dental implants are now a very mature technology commonly used in dentistry. As long as you do not have severe hypertension, heart disease, diabetes, jaw tumors, metabolic disorders, no history of maxillofacial radiotherapy within five years, and serious periodontal disease that has been thoroughly treated, we can consider implant prosthetic restorations; with the improvement of implant technology and implant systems, most recent literature has reported a 5-year success rate of over 95% and a 10-year success rate of over 90% for implants. Longer implants have been reported to be used successfully for more than 40 years. Therefore, as a restorative alternative to our missing teeth, implants are the most ideal restoration method after tooth loss in terms of appearance, sensation and chewing function, which are closest to our natural teeth.
