Background

Dentures are what is commonly known as "dentures". As with "artificial leg", "prosthesis" and "prosthetic" are referred to as "prosthetic", the term "prosthetic" is meant to refer to the teeth that "obligate" a human. In recent years, a faster and newer technical method has been developed in which an implant is implanted into an alveolar bone, and after the implant is osseointegrated with the alveolar bone, teeth are inserted into the implant.
