Osstem TS and Hiossen ET: Which exocad Libraries to Download
Osstem and Hiossen are not two different manufacturers but a single implant system under different brands. Osstem operates in the Asian and European markets, Hiossen offers the same products for the US market. That's why every file in the catalog is tagged as Osstem/Hiossen, and searches like *osstem ts library exocad* and *hiossen et library* lead to the very same CAD geometries.
Understanding this saves time: there's no need to look for a "separate" Hiossen library if you're holding an implant marked Osstem, and vice versa. Let's break down which product lines exist, what the prefixes in the names mean, and exactly what to download for a specific clinical case.
Osstem TS library for exocad: the main product line
The most widely used line in the system is TS (often called TSIII in the clinic), a tapered implant with an internal conical connection and an anti-rotational hex. Most *osstem ts library exocad* searches point to it, and in the DentalLibs catalog these are among the brand's most popular files.
The base option for designing crowns and bridges at the abutment level is Osstem/Hiossen TS DR Standard. It makes sense to start here for a standard single-unit or bridge case on the TS platform.
For temporary restorations, the same line has dedicated files (TS DR Temporary, TS Temporary stock) — these are used when designing a provisional restoration right after placement.
Hiossen ET library and other families: SS, KS, US
Besides TS, the system has several other lines, and they're easy to mix up when selecting. The search *hiossen et library* refers to the ET-type family — handled by Osstem/Hiossen ET-type Regular.
The remaining families in the catalog:
- SS — the submucosal line (SS SBO, SS SB) with CU, LI, CO, OT variants;
- KS — a separate family (KS SBO CU, KS SBO LI);
- US — the US SB / US SBO line with CE, CU variants;
- TS — the main tapered line with the broadest set of components.
What TS DR Minus and Plus mean in a library name
TS file names include prefixes like DR Minus10/20/30/40 and DR Plus10/30/80. These are angle-corrected variants: the number indicates the channel angulation the component geometry is designed for. Such libraries are used when the implant axis doesn't match the axis of the future crown and an angulated screw access is needed.
The practical takeaway is simple: first determine the required angle based on the surgical situation, then download the corresponding variant. Don't download the whole Minus/Plus set "just in case" — it only clutters the library list in exocad and increases the risk of picking the wrong file during design.
NP/RP platforms and Ti-Base T3/T5 on Osstem TSIII
TSIII comes in a narrow (NP, narrow platform) and a regular (RP, regular platform) platform — they can't be mixed, the interface differs. For work at the implant level, use Implant-level files, for example Osstem/Hiossen OSS TSIII NP Implant-level for the narrow platform.
When the restoration is made on a titanium base (Ti-Base, titanium base), you need the dedicated file for the specific height and base type: in the catalog these are the Custom-TiBase T3, T5 variants and the angled Custom-TiBase-Angled. A straight T5 base for the RP platform is Osstem/Hiossen OSS TSIII RP Custom-TiBase T5.
Multi-Unit and All-on-4 on Osstem/Hiossen
For fixed-removable work and All-on-4 / All-on-6 protocols, the system has the Multi-Unit (MU) level. The catalog has dedicated files for it: Osstem/Hiossen TS MultiSB MU, TS SBO MU, plus angled variants like TS SBO MuATi and the Multiangle multiunit line.
The logic is the same as for any full-arch work: design happens not at the implant level but at the multi-unit abutment level, so you need a library of the MU type. Implant-level files won't work for a full arch — the bar or framework won't seat on the multi-unit analogs.
How to choose the right Osstem/Hiossen library
To avoid downloading extras and making mistakes, check against the implant label or the surgeon's order along three coordinates:
- line — TS, SS, KS, US or ET-type;
- platform/diameter — NP or RP for TSIII;
- restoration type — implant level, on Ti-Base or on Multi-Unit;
- whether an angle is needed — then take the Minus/Plus or Angled variant.
All the listed Osstem/Hiossen files are available in the DentalLibs catalog as part of the large section of implant libraries for exocad. Download selectively for the task at hand — that keeps the list in DentalCAD clean and minimizes the risk of picking the wrong interface.
Frequently asked questions about Osstem and Hiossen libraries
Are Osstem and Hiossen the same library?
Yes. It's one system under two brands, and the files are tagged Osstem/Hiossen in the catalog. For a Hiossen implant, use the Osstem library with the same line and platform.
Which library should I download for an Osstem TS single crown?
Start with Osstem/Hiossen TS DR Standard at the abutment level, or with the dedicated Ti-Base for the required height if the restoration is made on a titanium base.
Where can I find the Hiossen ET library?
It's the Osstem/Hiossen ET-type Regular file. There's no separate library under the Hiossen brand — look for ET-type in the Osstem/Hiossen section.
What's the difference between NP and RP on TSIII?
These are the narrow and regular platforms with different connection interfaces. The libraries are not interchangeable — pick the file strictly for the implant's platform.
