Abstract
It divides it roughly, and a fixed style of the fixed prosthesis implant superstructure is cement retained, and screw retained. The domination of excellent screw retained in maintenance recovery Ritoribabiriti is high though appreciation of the beautiful is requested while being acknowledged assuming that the implant treatment foresees and is high, and a lot of cement retained is adopted. However, a difficult point of the screw retained is achievement of the agreement of high accuracy.
The production of a screw retaining superstructure with high promptness and accuracy becomes possible without depending on the difference between the experience and the technology by using together about Fazar (TIG welding) and soldering plan though one peace casting and soldering plan need the skill level and both experience values. .
