Implant-Supported Fixed Prostheses
Implant Fixed Restoration Concept
Implant-supported fixed prosthesis is a crown, bridge or full arch restoration attached to dental implants with completed osseointegration. It cannot be removed by the patient; Increased chewing comfort and stability can be targeted compared to removable dentures.
Implant-supported crowns can be planned for single missing teeth, and implant-supported bridges or segmental restorations can be planned for multiple missing teeth. The number of implants, their position and bone quality are evaluated with CBCT.
Retention Systems
Fixed prostheses can be attached to the implant abutment with screw-retained or cement-retained. Each system has different advantages in terms of maintenance, repair and aesthetics; The selection is made on a case-by-case basis.
Abutment selection can be standard or special production; Gingival profile is important in the aesthetic area.
Prosthetic Stage and Temporary Restoration
Temporary prosthesis can be used during the recovery period after implant placement. Final restoration production can be done with digital impressions and CAD/CAM.
Occlusion adjustment, contact points and implant load distribution are critical for long-term success. Excessive occlusal load may contribute to peri-implant bone loss.
Difference from Screw and Bar Systems
This category covers general fixed implant prostheses; Screw prostheses offer the advantage of detachability, while bar systems are supported by removable prosthesis. Locator removable overdenture is a different approach.
All-on-4 or All-on-6 full arch fixed prostheses are special subtypes of this group.
Care and Peri-implant Health
Brushing around the implant, using an interface brush and dental floss are important. Smoking may increase the risk of peri-implantitis.
Inspection and imaging can monitor implant and restoration status. Screw loosening or ceramic fracture may require early intervention.
Implant Number and Distribution
In free-end bridges, the number of implants and spacing are critical in planning. Surgical support such as a short implant or sinus lift may be required in the posterior region.
It is recommended not to place excessive load on the implant during the temporary prosthesis integration period.
Prostheses attached with cement may be preferred because there is no screw hole in the aesthetic area; Cement overflow can cause peri-implant problems. Systems fastened with screws may offer the advantage of detachability.
Smoking may increase the risk of peri-implantitis; Hygiene around the implant requires regular control.
After implant prosthesis delivery, occlusion fine-tuning and patient education are part of the care process.
X-ray follow-up can be planned according to clinical need to monitor peri-implant bone level.
