Overview

The Bone Level implant is the parallel-walled original of Straumann’s bone-level range, and it introduced the CrossFit connection that BLT still uses. Its body is a straight cylinder with an 0.8 mm thread that tapers off coronally, which makes it a conventional choice in healed, reasonably dense bone rather than in fresh sockets. Compared with BLT it offers a narrower length range — 8 to 14 mm — and no apical taper, so surgeons who want extra primary stability generally move to BLT or BLX rather than to a longer BL. The important compatibility point is that BL and BLT share prosthetic components, while BLX and TLX do not, because those use TorcFit instead.

Technology

Clinical positioning

What the manufacturer says this system is designed for. This is not the same thing as independent clinical evidence, which is set out separately below.

Straumann describes Bone Level implants as suitable for bone-level treatments in combination with trans- or subgingival healing, and lists BL ∅ 3.3 mm NC for narrow interdental spaces and ridges, with the ∅ 4.1 and ∅ 4.8 mm implants for general endosteal indications in the maxilla and mandible.Manufacturer-reported

The clearances below are held by Straumann at brand level and cover its implant range, not Straumann Bone Level specifically. We show them here because that is the level at which regulators actually issue them.

Regulatory record

Read this before drawing conclusions. A clearance or certificate means a device may legally be sold in a market. It is not a finding that the implant performs well, and it is not a comparison against other implants. In particular, FDA "clearance" is not FDA "approval" — clearance means the FDA accepted the device as substantially equivalent to one already on the market. What these actually mean →

FDA 510(k) clearance30 records

Cleared as substantially equivalent to a predicate device. Not an FDA approval, and not a finding of safety or effectiveness.

1219 device records—Straumann—

Clearance records for Straumann were retrieved from the issuing authority's own database, not from the manufacturer's marketing material. We attribute a clearance to a brand only when the filing holder belongs to that brand's corporate family — third-party clearances for compatible components are excluded, because they belong to the company that made the component, not to Straumann.
