What does “Types of implant prostheses” mean?
An implant prosthesis is the part connected above an implant in the bone to replace tooth form and function. Types include a single crown, a bridge replacing several teeth, a fixed full-arch prosthesis and a removable implant overdenture.
Determine the extent of replacement and whether it is removable
A crown replacing one tooth differs in extent from a bridge joining several replacements. In a toothless jaw, a fixed full-arch prosthesis or removable implant overdenture may be considered. Tooth count alone does not decide the design; space and hygiene conditions also matter.
Screws and cement are different connection methods
Fixed restorations may be secured with screws or cemented to abutments. Selection considers how the screw access opening affects appearance and the chewing surface, the fit of the prosthesis, and later removal, assessment and repair. Neither method eliminates complications in every situation, so ask about the actual connection design.
Compare materials and maintenance separately
Materials include metals, metal covered with porcelain, and ceramics such as zirconia, with differing properties and applications. Selection considers the area under load, required thickness and aesthetic needs. A material name cannot guarantee lifespan or prevention of fracture, and both tissues and the prosthesis require regular assessment.
Frequently Asked Questions
Does every implant need its own separate crown?
Not necessarily. Several implants can jointly support a connected bridge or full-arch prosthesis. The extent of the prosthesis and implant number and positions follow the overall plan.
Can I remove a screw-retained prosthesis myself to clean it?
No. A fixed screw-retained prosthesis is detached by a clinician when needed. Its cleaning method differs from an implant overdenture designed for patient removal.
Questions when choosing an implant prosthesis
Learn what the term means and how it relates to your dental condition.
- A choice suited to your condition
What form of prosthesis is planned, and will I remove it myself?
Explanation and evidenceConfirm whether the replacement is a crown, bridge, full-arch prosthesis or overdenture, its extent and the daily cleaning method.

What connection, material and later repair plan will be used?
Explanation and evidenceDistinguish the reasons for screw or cement retention from material selection, and ask what assessment, repair or replacement may involve if movement or fracture occurs.
