Abutment Modification in Cemented Retained Restoration for Increasing Retention: A Scoping Review of a Current Instrument

Cement-retained remain the most popular connection type in dental implant single crown. Cement retained offers simplicity, aesthetic crown, compensation for angulated implant, however there are disadvantages such as the difficulty for removing the excess cement, retrievability, and strictly not for minimum restorative space. Due to this disadvantage some researcher try to modified abutment surface in order to increase retention. Some of the studies suggest sandblasting, groove adding, extension cement to screw access channel, etc. The aim from this scoping review was to describe the modification of standard dental abutment cement-retained single implant crown. A scoping review was conducted to map types of modification on abutment cement-retained in order to increase retention on ten years of research (December 2010-December 2020). All studies were in-vitro and describe with three primary techniques (groove, screw access extension, surface treatment). According to the ten studies evaluated, the modification on abutment cement-retained was used mainly with sandblasting and extension screw access channel. Engaging the screw access channel and surface treatment remain the most suitable modification on the cement-retained abutment
