Overcoming the restorative challenges (esthetic, occlusal) of the screw access channel in a screw-retained implant restoration is difficult. By fabricating a pressed ceramic over metal crown and esthetic plug these challenges can be dealt with in a predictable manner.
The transition margin from an implant abutment to a crown is challenging to manage especially esthetically. Placing the abutment margin in a subgingival position helps hide the unesthetic transition, however, this reduces the ability to clean excess cement, increases the risk of peri-implant disease and the inability to control gingival sulcular fluids may affect the cement bond. The implant crown with an esthetic adhesive margin provides for supragingival bonded margins that can aid in complete removal of excess cement at the same time providing an esthetically pleasing result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
