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.

Straumann® SLActive®

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

Predictability

Implant survival rate in immediate loading after 10 years: 98.2%.9

Osseointegration

Reduced healing period from 6-8 weeks down to 3-4 weeks in all indications.*

Biology

Enhanced bone regeneration even at compromised sites.12

Performance

Implant survival rate in irradiated patients with compromised bone after 5 years: 100%.10,11

* compared to SLA®. Indications: from single tooth to edentulous.

Straumann® SLA®

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

Survival rates

High and consistent survival rates between 95.1% and 98.8% documented by different studies after 5 and 10 year follow-up.14-20

Bone preservation

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

Straumann® ZLA®

A surface with revolutionary osseointegration features.

Straumann® ZLA® is the surface of the Straumann® PURE Ceramic Implant System and features revolutionary osseointegrative properties that are equivalent to the well-established original Straumann® SLA® surface.

Structure

Similar in macro- and micro-roughness to SLA®.

Osseointegration

Healing time comparable to SLA®.21-23

Esthetics

Less plaque attachment – an important factor for long-term implant success23.
