Osseointegrated implant for single-tooth replacement: a retrospective multicenter study on routine use in private...

Area of Science:

• Dental Implantology
• Prosthodontics
• Oral Surgery

Background:

• Dental implant restorations evolved from full arch to partial edentulism.
• Recent studies validate single-tooth replacement with dental implants.

Purpose of the Study:

• Evaluate Brånemark implant survival rates.
• Assess prosthesis stability for single-tooth replacements.
• Determine suitability for routine use in all oral regions.

Main Methods:

• 252 Brånemark implants placed in 214 patients over 8 years.
• Single-tooth replacement protocol followed across five Italian private clinics.
• Data analyzed using established evaluation methods.

Main Results:

• Cumulative survival rate (CSR) reached 96% after the first year and remained stable.
• 10 implant failures recorded out of 229 restorations.
• Abutment screw loosening was the most frequent complication (35%), primarily with older abutment designs.

Conclusions:

• Brånemark implants show a high survival rate comparable to multicenter studies.
• This treatment modality is reliable for routine single-tooth replacement.
• Modern abutment designs, like CeraOne, significantly reduce complications.
