Prostheses on implants, what are they?

Prostheses on implants, what are they?

Prostheses on implants are what we know as crowns (sheaths), bridges or complete prostheses that are placed on top of any implant integrated in the bone. But in practice, prostheses that substitute all the natural teeth of one or both arches of a patient are called “prosthesis on implants”, which would be known as complete rehabilitation.

Types of prostheses on implants

  • Fixed prosthesis on implants: These are full-arch dental prostheses that are fixed screwed or cemented on six or eight implants integrated into the bone. These restorative dentistry treatments replace all the teeth of one or both arches with a prosthesis or “fixed denture” fixed on a reduced number of dental implants, which fulfill the biomechanical functions of the natural roots of the teeth. The fixed prostheses on implants are totally personalized, these are made with either ceramic-ceramic or zirconium-ceramic.
  • Overdenture: Overdentures are removable prostheses (to remove and put) as dentures, which are placed on dental implants. As a general rule, fewer dental implants are needed than with a fixed prosthesis, and may be recommended for patients who have lost labial support or those in whom placing a fixed prosthesis would involve bone regeneration surgeries and the patient did not want to. Instead of being fixed to the implants, we can remove it and put it on, which facilitates oral hygiene.
  • Hybrid prosthesis on implants: These prostheses are recommended for patients with considerable bone resorption, product of tooth loss for a long time, since part of the prosthesis simulates the gum tissues, these are made with acrylic materials, that does not make them so aesthetic, in addition to that to clean them the specialist must unscrew the prosthesis which makes hygiene very difficult, and forces the patient to make more visits to keep it in good condition.
