Cement-Retained Restoration
An implant-supported prosthetic crown or bridge bonded to its abutment using dental luting cement, without a retaining screw.
Full Definition
A cement-retained restoration relies on a luting agent — provisional or permanent — to bond the prosthetic crown to the abutment, mirroring the approach used with tooth-supported crowns. Editors working on clinical outcome papers must recognise that excess cement at or below the gingival margin is a documented risk factor for peri-implant disease, and text that omits this consideration may require a note to the author. The term must be clearly distinguished from 'screw-retained restoration' throughout a document. In cost-effectiveness analyses and insurance coding documents, the distinction between cement-retained and screw-retained impacts treatment codes and should be verified. Some authors abbreviate to 'CR restoration,' which should be spelled out on first use.
Usage
Usage note: Hyphenate as 'cement-retained' when used as a compound modifier. Spell out on first use if abbreviated to 'CR restoration.'
