Together with leading clinicians worldwide, Straumann has studied the clinical performance of SLActive® implants under the most challenging medical conditions and treatment protocols to demonstrate the outstanding healing capacity of the SLActive® surface.

As new insights emerge and new data becomes available, discover how you can benefit from the high performance SLActive® surface to support your patients’ healing capabilities.

Immediate loading

with long-lasting results.

Immediate loading allows the patient to benefit from the restoration straightaway after implant placement. 
However, this demanding protocol carries a higher risk of implant failure.

  • New long-term data from randomized, controlled, multicenter study demonstrates impressive performance of SLActive® with immediate loading.
  • In fact, the SLActive® implants delivered a 10-year survival rate of 98.2 % in this challenging protocol.2

SLActive® in irradiated patients.

Predictability beyond expectations

One of the most challenging patient groups for implant treatment includes patients who have undergone a combination of tumor surgery, chemotherapy and radiotherapy. The bone quality in these patients is severely compromised.

SLActive® Performance in irradiated patients

1-year follow-up3

1 patient was excluded from the study due to tumour recurrence. The graph is thus based on 19 patients with 97 implants.

5-year follow-up13,14

Excluding 4 further patients deceased due to cancer The graph is thus based on 15 patients with 79 implants.

Randomized Clinical Trial:3
  • 102 implants, 20 patients
  • Post-surgery, radiotherapy and chemotherapy for oral carcinoma

Uncompromised performance.

Even in diabetic patients.

  • Patients with diabetes have reduced wound healing capacity,15,16 which puts implants at risk
  • Worldwide, 1 in 6 adults 60 years of age and older  has diabetes.17

Given the ever rising prevalence of type 2 diabetes, how can clinicians address this risk particularly in older patients?


A new clinical study19 that compared SLActive® performance in patients with and without dia­betes showed uncompromised performance of SLActive® implants:

  • 100 % implant success rate in the diabetic group
  • Bone changes similar to those in healthy individuals
  • Despite the observed lower levels of bone quality all implants in this study showed good primary stability.

What clinicians say

New research shows SLActive® surface stimulates an early anti-inflammatory cell response compared to non SLActive surface as measured in vitro as a reduction in pro inflammatory markers* and an increase in anti-inflammatory** markers.
  • Roxolid SLActive® surface stimulates an early anti-inflammatory cell response20
  • SLActive® is associated with an increased anti-inflammatory macrophage response in the early healing phase in both healthy and diabetic animals. This may be an important mechanism to improve osseous healing under compromised systemic conditions.21
Brand new data on the SLActive®’s anti-inflammatory cell response has been presented at the 95th General Session of International Association for Dental Research, US:

Enhanced bone regeneration.

Even at compromised sites.

Bone Grafting

Bone defects can greatly compromise the predictability of osseointegration.

  • In a recent preclinical study22, SLActive® showed significantly higher formation of new bone aggregate within eight weeks compared to the standard Straumann® SLA® hydrophobic surface.
