If more teeth and molars are missing in your teeth, we speak of a mutated teeth. You may have lost elements in a period of poor care or as a result of an accident. It is also possible that a number of teeth and molars have not been applied to you. We then speak of agenesias. Either way, your teeth don't look the way you want.
Missing elements can be supplemented with the help of bridges or implants. There are of course all kinds of removable features, but because this book is about cosmetic dentistry, these more functional than beautiful aids are not taken into account.
Implantology has expanded enormously in recent years. In the first instance, implants were mainly used to give dentures a hold on the jaw, the so-called click prosthesis, nowadays implants are an indispensable part of restorative dentistry. The advantage of an implant for tooth replacement is that only the missing tooth is replaced, neighboring elements do not need to be ground since they are not used for support.
There are of course disadvantages too. Inserting an implant is an operation and every operation involves risks. The most important are wound infection and the loosening of the implant. Other risks are damage to the root of a neighbor element or a nerve in the jaw. To prevent these problems, X-rays are taken prior to treatment to view the condition of the jaw bone and the location of the neighboring elements. A few people continue to have pain with an implant.
