Aesthetics is not a minor aspect in the current times, that is why Moderna dentistry nowadays has that dental absences can be rehabilitated by fixed dentures routinely, a fixed prosthesis consists of a device made to measure the patient's mouth with one or several teeth that is placed in the mouth to replace the loss of teeth. We could distinguish two types of fixed dentures, those that are fastened by dental implants, and those that rest on the patient's healthy teeth.

• Fixed prosthesis on teeth: In this case the prosthesis is fastened on the patient's own healthy teeth, so that a great support and firmness is achieved. To do this, the dentist needs to carve and wear both in width and height the 2 teeth located at the ends of the edentulous area (without teeth), forming what is known as a stump, so that later the prosthesis can fit on them to be able to cement it and thus achieve a durable fastening.
  
• Fixed prosthesis on dental implants: In this case the prosthesis is attached on one or several titanium implants that act as the root of the tooth, and on which the dental prosthesis is attached, either a crown or a bridge with several pieces. Within this type of technique there are also immediate loading implants, with a drastic decrease in the treatment time, not having to suffer long periods without the use of fixed teeth and recovering the function and dental aesthetics in a single day.

The implant treatment can be performed immediately, by placing the crown (tooth) directly after the implant placement.This means that the patient can eat and smile immediately after the treatment.
