| Research Abstract |
Recently, magnetic attachments have gained great popularity in prosthodontic procedures in Japan. The root caps for magnetic attachments are designed to be flat in shape with minimal vertical dimension. So that, the abutment tooth can be free from destructive loads such as lateral and/or rotational stress.
Magnetic attachments are also applicable to the implant system throgh the introduction of a specially designed keeper. This keeper is about the same shape as the abutment piece. The keeper is made of magnetic stainless steel.
After confirming the osseointegration of the fixture, a keeper is screwed on to the abutment. Natural abutment teeth can be free from destructive loads using magnetic attachments. This system also applies to the implant, very simple fabrication procedures for dentures on the implants are possible.
The properties of the surface of the implant keepers were not change by potential difference during thiese clinical cases. Then, it was cofirmed utility of magnetic attachments for oral implant treatment.
