Overview

The MS system is a one-piece narrow implant, which makes it a structurally different object from the TS fixtures rather than simply a thinner version of them. Because the abutment is machined as part of the implant, there is no screw joint to loosen — but there is also no way to change the abutment angulation later, and the implant must be placed in the position the final restoration requires. Osstem separates the range into narrow-ridge, denture and provisional indications, and the denture variants are the most common reason a patient encounters one. We have not been able to confirm the available lengths from a primary Osstem document, so that field is deliberately left empty.

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.

Osstem describes three uses: MS Narrow Ridge for narrow bone or interdental sites, MS Denture for denture support in edentulous patients with narrow bone, and MS Provisional as a temporary implantManufacturer-reported

The clearances below are held by Osstem at brand level and cover its implant range, not Osstem MS 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.
