To replace one or more missing teeth dentists often use prosthetics. There are two different types: fixed and removable.
Now we will explain the different techniques of fixed prosthetics used to replace a missing tooth.
The Bridge with crowns on natural teeth
This bridge is a fixed prosthetic composed of two crowns linked by an artificial tooth that replaces the missing tooth ( or teeth ) by supporting itself on the surrounding teeth. The teeth that support the bridge are called the pillars and they need to be prepared and reduced on every side to be able to place the two crowns. This is done by grinding down the pillar teeth to obtain the necessary preparations. This bridge is made of gold and covered by ceramic material.
Crown on an implant
A crown on an implant is a fixed prosthetic. It is composed of a screw, normally of titanium, that passes through the gum and is inserted on to the bone after one or more surgical intervention to replace the root of the missing tooth. Then the crown is attached to the implant.
The implant technique can replace a single tooth, to fill a space more or less important between two teeth or, to maintain a denture in a partially toothless jaw. Contrary to the root of a tooth, the implant is in direct contact with the bone, it is called Osseo Integration. This lack of ligament means that there is no damping system to protect the bone pressures created by the impact on the teeth during swallowing, chewing or grinding of teeth.
As illustrated above, the implant is composed of two parts:
