Straumann implants: history, features, models

Roxolid is a patented Straumann alloy used in selected dental implant lines. It consists of 85% titanium and 15% zirconium. According to the manufacturer, Roxolid has 80% higher tensile strength compared with standard Grade 4 titanium.

Thanks to the high strength of the material, in certain clinical situations the doctor can use smaller-diameter implants or shorter implants. This may be relevant in cases of bone deficiency, when it is important to reduce the invasiveness of the procedure and, where possible, avoid or minimize bone augmentation.

Implants with an SLA surface undergo two processing stages: first sandblasting, then acid etching. As a result, a micro-rough surface is formed, increasing the contact area between the implant and bone tissue and supporting the osseointegration process.

SLActive is a hydrophilic modification of the SLA surface. Because it interacts better with biological fluids, this surface promotes more predictable initial healing and accelerated osseointegration. Implants with an SLActive surface can be useful in more complex clinical protocols, especially when high primary stability and early or immediate loading are important.

Such implants may be considered for patients with risk factors that require particularly careful implant planning. These factors may include insufficient bone volume or reduced bone quality.

BLT Bone Level Tapered implants are made from the Roxolid alloy. They have an SLActive surface, a CrossFit connection, and a Bone Control Design aimed at preserving bone tissue in the implant area.
Possible clinical situations for use:

• implant placement in the area of the lower central and lateral incisors;
• implant placement in the area of the upper lateral incisors;
• narrow edentulous sites;
• wide edentulous sites;
• limited thickness of the alveolar ridge;
• sufficient thickness of the alveolar ridge;
• complete edentulism of both jaws;
• partial edentulism of one or both jaws.

BLX Bone Level X implants are made from the Roxolid alloy. They have an SLActive surface, a TorcFit connection — a universal implant-abutment connection — and an active bidirectional thread designed for high primary stability.

Possible clinical situations for use:

• implant placement in the area of the central and lateral incisors of the lower and upper jaws;
• narrow and wide edentulous sites;
• limited thickness of the alveolar ridge;
• sufficient thickness of the alveolar ridge;
• complete or partial edentulism of both jaws;
• implant placement in the area of different tooth groups, in soft or dense bone, with the possibility of early or immediate loading when clinically indicated.
