1. Features
-It has a design of moving head which does not convey bite forces to the Magic FC since it moves as much as overdenture’s movement during mastication.
-It gives sufficient retention force for a long time and error of practitioners can be recovered.
-When overdenture is fixed, it guides the moving abutment to be connected easily.
2. Advantages
-It requires less surgical time as only two narrow fixtures are placed with one-time drilling regardless of location, maxillary or mandibular.
-Both patients and doctors know re-basing time; therefore, the re-basing done at right time will keep fixtures free from occlusal force.
-Direction can be corrected at abutments consequently, undercut retentions can be used despite errors in placement.
