Figure (1) Clinical case, intraoral view at the first visit
Figure (2) Technical drawing of the one-step-type implant
Figure (3) (4) Clinical case after an insertion of the final superstructure. Note the excellent soft and hard tissue responses.
Figure (5) Technical drawing of the two-step implant
Figure (6) Taper lock abutment exposed in the oral cavity
Figure (7)(8) The implant replacing a maxillary anterior tooth. Period of clinical function is 36 months. Note the excellent bone response around the implant and lack of evidence of crestal bone loss.
Figure (9) On the palate side of the superstructure, a small hole for the superstructure remover is observed
Figure (10) For full arches, prosthetic retrieval is relatively rapid and easy because it is not fixed with multiple screws, requiring only release of frictional force using an superstructure remover
Figure (11) The principle of superstructure remover. Using an superstructure remover, the frictional force is released, facilitating an easy superstructure removal.
