An implant oral prosthesis is any component that is attached (whether it's fixed or non-fixed) to the dental implant or multiple implants to mimic the function and appearance of the dentition or teeth.

Dentures can also be referred to an oral prosthesis since it is worn in the mouth for the same reasons but they are not attached to dental implants but instead are held into place by teeth or by other natural or self-applicable means (intraoral muscles, suction, denture adhesive, etc.).
