Implant-supported restoration refers to the prosthetic structure placed on a dental implant that has been inserted into the jawbone. The implant is not merely a screw; it is an artificial tooth root onto which a crown, bridge, or denture can be placed.
Types of Implant Restorations
- Single-tooth crown: A crown placed on a single implant, independent of adjacent teeth.
- Implant-supported bridge: A fixed bridge supported by one or more implants for multiple missing teeth.
- Overdenture: A removable denture retained on implants that the patient can remove. May be preferred in fully edentulous cases.
- Fixed full-arch bridge (All-on-X): A full-arch bridge placed on multiple implants that the patient cannot remove.
Prosthodontic Planning
The restoration type is determined by implant position and number, bone structure, occlusal relationship, aesthetic expectations, and the patient's overall condition. Prosthodontic planning should be performed before the surgical phase so that implant positioning aligns with the restorative goals.
Material Selection
Implant crowns are generally made from zirconia or porcelain-fused-to-metal (PFM). Aesthetic priority materials are preferred for anterior teeth while durability may take precedence in posterior regions. Material selection is made based on clinical conditions for each case.
