The classic prosthesis for edentulous patients has numerous disadvantages. The total chewing force is normally absorbed by the teeth, and transmitted as a tensile force via their fiber connections to the bone. In a jaw with teeth, the teeth are anchored in the bone by a fibrous structure, which transmits chewing forces as tensile loads, stimulating the bone to grow in order to adapt to these loads.
The use of implants offers better options for full dental prostheses. The placement of even a few implants means that these can absorb a majority of the loads, thus providing excellent support for a prosthesis. High pressure on the bone is avoided, ensuring that the prosthesis fits well for a significantly longer period of time in most cases. Retention attachments are usually placed on the implants; these ensure that the prosthesis is held more securely in place. Despite this, the patient can easily remove the prosthesis for daily cleaning.
