Overview

TS III SA is the fixture most people mean when they say “Osstem implant”, and it is a conventional tapered bone-level design rather than anything unusual: an internal hex sitting inside an 11-degree taper, a corkscrew thread, and a blasted and acid-etched surface. The letters after the name matter more than the name itself — SA is the plain sandblasted and acid-etched surface, while CA is the same physical surface stored in solution so that it stays chemically active, and the two are not interchangeable when reading a treatment plan. The range is unusually wide, running from Ø3.0 up to Ø7.0 mm and including 4 mm and 5 mm ultra-short fixtures at Ø5.0, and Osstem’s own instructions place real restrictions on those shortest options. A patient told they are receiving “an Osstem TS” has therefore been told very little; the diameter, the length and the surface variant are the parts that describe the actual implant.

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.

Presented by Osstem as a general-purpose fixture for a wide range of cases, with a fixture of Ø4.5 mm or more recommended for single posterior restorationsManufacturer-reported

Further detail

Short implant option	Extra-short options are offered; the instructions for use restrict implants shorter than 7 mm with a diameter of 5 mm or more to the molar region and advise splinting and a longer healing periodManufacturer-reported[1]
Immediate protocol	Recommended placement torque below 40 Ncm; the catalogue states the fixture acquires initial fixation for immediate loading in soft boneManufacturer-reported[1]
Geographic availability	Requires manual verification(Regulatory clearance and distribution vary by market.)

The clearances below are held by Osstem at brand level and cover its implant range, not Osstem TS III SA 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) clearance5 records

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

Clearance records for Osstem 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 Osstem.
