3. Implant surface osseoconductivity1 Relation to crestal bone maintenance Improved osseointegration may lead to

improved bone maintenance

Implementation in Straumann® Bone Level implants

By using SLActive™ all surface benefits apply

Accelerated osseointegration* Increased treatment predictability* Reduced healing times Increased confidence

Relation to crestal bone maintenancemicrogap bacterial contamination inflammation (peri-implantitis) bone resorption

Implementation in Straumann® Bone Level implants Conical Connection The conical connection is designed to provide a seal

and minimize the sensitivity to lateral forces

4. Biomechanical implant design

Relation to crestal bone maintenance Strength to withstand chewing forces Bone must be stimulated in a certain range to be

maintained and not overused or resorbed

Implementation in Straumann® Bone Level Implant Excellent fatigue strength Flat neck portion, similar to S/SP/TE implants Excellent force transmission with a novel connection

5. Respecting the biological distance4 Relation to crestal bone maintenance Respecting the biological distance is a key factor for

preserving the crestal bone level

Implementation in Straumann® Bone Level Implant BL: horizontal offset (biological distance) TE: vertical offset (biological distance) Keep the microgap away from the bone

2. Optimal position of smooth and rough surface

Relation to crestal bone maintenance A rough surface that extends over the bone crest has the

tendency to preserve crestal bone

Implementation in Straumann® Bone Level Implant The rough/smooth surface interface of the Straumann®

Bone Level Implant is located at the top of the implant shoulder

Surgical Procedure: The Straumann® Bone Level Implant is generally placed at bone level
