Survival and Success Rates of 6mm Implants With a Micro-rough Surface After 4.5 - 18.2 Years in Function

Completed

• Conditions: Jaw, Edentulous, Partially; Dental Implant Failed; Implant Complication

• Registration Number: NCT04017026
• Lead Sponsor: University of Bern

Brief Summary

In this retrospective study, approximately 60 patients treated with 6mm short implants (Straumann, SLA (sandblasted, large-grit, acid-etched surface), SLActive (sandblasted, large-grit, acid-etched, hydrophilic surface), 4.1 or 4.8 mm in diameter) will be followed for 4.5-18.2 years. Clinical and radiographic parameters will be assessed in a follow-up examination.
