Surfaces of the Straumann® Dental Implant System
Redefining the boundaries of what is possible.
From the industry benchmark SLA® to the high-performance SLActive® implant surface, Straumann has constantly raised the bar to set new standards in osseointegration. ZLA®, developed for the Straumann® PURE Ceramic Implant, continues this tradition.
How can we help you?
Performance beyond imagination.
SLActive® is Straumann’s high performance surface with extensive healing potential. It stands for high predictability and accelerated osseointegration1-8. Recent studies show an outstanding clinical performance of SLActive® implants even in very challenging treatment protocols and patients with compromised health.9-11
Implant survival rate in immediate loading after 10 years: 98.2%.9
Reduced healing period from 6-8 weeks down to 3-4 weeks in all indications.*
Enhanced bone regeneration even at compromised sites.12
Implant survival rate in irradiated patients with compromised bone after 5 years: 100%.10,11
* compared to SLA®. Indications: from single tooth to edentulous.
Longevity and efficiency in daily practice.
The classic SLA® surface, introduced in 1998, is based on a large-grit sandblasting technique that generates a macro-roughness on the titanium surface. This is followed by acid-etching that superposes a micro-roughness. The resulting topography offers an ideal structure for cell attachment. Many peer-reviewed clinical and preclinical studies have confirmed its strong long-term performance and reliability, making it one of the best documented surfaces in dental implantology. According to an independent study, the odds ratio of developing peri-implantitis was more than three times higher in patients treated with competitor implant systems compared with Straumann® implants with SLA® surfaces.13
High and consistent survival rates between 95.1% and 98.8% documented by different studies after 5 and 10 year follow-up.14-20
Average bone loss of 0.5-1 mm after 10 years (baseline defined as implant loading time).15,16
Low prevalence of peri-implantitis
Very low prevalence of peri-implantitis (1.8%) over the 10-year follow-up period.15
A surface with revolutionary osseointegration features.
Similar in macro- and micro-roughness to SLA®.
Healing time comparable to SLA®.21-23
Less plaque attachment – an important factor for long-term implant success23.
