Prosthetic Table
The supragingival platform surface of a dental implant or abutment on which a prosthetic restoration is seated and retained.
Full Definition
The prosthetic table refers to the flat or contoured bearing surface at the coronal end of an implant abutment upon which a crown, bridge, or bar is placed. Its dimensions influence the marginal fit of the restoration, load distribution to the implant body, and aesthetic outcome. Prosthetic table dimensions are a critical specification in implant-prosthetic catalogues and are particularly relevant in platform-switched configurations, where the table diameter is intentionally smaller than the implant diameter. Editors working on implant manufacturer documentation and laboratory prescriptions will encounter this term frequently. It should not be confused with 'occlusal table', which refers to the biting surface of a tooth or crown.
Usage
Usage note: Do not confuse with 'occlusal table', which describes the masticatory surface of a tooth. In laboratory prescriptions, confirm whether 'prosthetic table' refers to the abutment or the implant platform, as the terms are sometimes used loosely.
