The prospective, investigator-initiates study* focused on the edentulous mandible, using immediate load and fixed prosthesis. The 10-year data reported exceptional long-term clinical results — 100% implant and prosthetic survival rate with minimal, 0.3 mm average bone level reduction — for immediately loaded OsseoSpeed implants.
"I am very proud, but not at all surprised, that we can present such solid long-term clinical results on the Astra Tech Implant System, as documented research is the foundation of the continuous development of our implant systems. In fact, we have solid, long-term clinical results on all our three implant systems. It really proves our commitment and dedication to science and clinical research," says Anna-Karin Lundgren, DDS, PhD, Director Global Clinical Affairs at Dentsply Sirona Implants.
The implant systems — Astra Tech Implant System, Ankylos and Xive —are continuously documented and they are clinically proven to provide successful implant therapy for life-long function and esthetics.
Astra Tech Implant System
The extensive literature, approximately 1,000 publications, shows safe, consistent and predictable results for Astra Tech Implant System in terms of high implant survival rate and well maintained marginal bone. With more than 9,000 patients followed prospectively up to 20 years, the data shows implant survival rate above 98% and 0.3 mm average bone level reduction at the 5-year follow-up. Long-term clinical results up to 20 years are available.
Ankylos implant system
With up to 17 years of clinical reliability, a retrospective analysis** of 18,945 Ankylos implants placed in a large patient population (7,783 patients) showed successful long-term clinical results when using a flapless surgical approach. The Ankylos implant system has been in clinical use for more than 25 years and shows high survival rates and favorable esthetic results.
Xive implant system
With up to 15 years follow-up, data on Xive implants*** shows >97% survival rate, stable marginal bone levels, and favorable soft tissue conditions. The clinical documentation on 265 patients and 458 implants show excellent outcomes for single tooth, partial prosthesis, extraction sockets, immediate and delayed loading.
Science and clinical research
Long-term clinical documentation is one of the most important tools to show a product's efficiency, reliability and safety. Dentsply Sirona Implants focuses on research and development in all aspects of implant treatment, supported by extensive pre-clinical and clinical study programs. The comprehensive documentation includes more than 2,000 published scientific references to date and the products are researched, developed, documented and clinically proven to provide successful implant therapy for life-long function and esthetics.
