Neodent vs SIN: What to Choose and Which CAD Libraries

Neodent and SIN are the two largest Brazilian dental implant manufacturers, and the query "neodent vs sin implant" comes up more and more often among surgeons and technicians working with Latin American systems. Both brands rely on conical connections, hydrophilic surfaces and high primary stability. But when you move into the digital workflow, a different question takes center stage — how convenient is it to plan the system in exoplan, and is there a ready-made CAD library for it. Below we break down the connection geometry, the key product lines and the real availability of libraries for exocad and exoplan.

Neodent and SIN: What the Brazilian Brands Are Known For

Neodent has been part of Straumann Group since 2012 and became the most widely used implant in Latin America, and it now sells actively across Europe, the US and Asia. This explains why there is an extensive set of libraries for Neodent in exocad and exoplan — the brand is supported at the level of the global Straumann protocol.

SIN (Sistema de Implante Nacional) is an independent Brazilian manufacturer, strong first and foremost in its domestic market. The company offers its own implant lines and surgical kits, but its international distribution and, consequently, its CAD library coverage are more modest than Neodent's.

Neodent Connections: Grand Morse (GM), Cone Morse (CM) and External Hex

Neodent's current platform is Grand Morse (GM): a Morse taper connection with a single prosthetic platform across all implant diameters. This simplifies component inventory and library selection — a single GM interface covers most clinical situations. The earlier Cone Morse (CM) line also uses a Morse taper, while external hex (HE) appears in classic series such as Titamax.

The main implant families are Helix GM (fully conical design), Drive GM/CM (for high primary stability in soft bone), Alvim CM and the single-stage Facility for overdenture constructions. Surfaces come in two options: the sandblasted, acid-etched NeoPoros and the hydrophilic Acqua. In exoplan this is reflected directly in the library name — for example Helix GM Acqua and Drive GM NeoPoros.

SIN implant: Strong and Unitite Lines and Connection Types

SIN follows its own product-line logic. The Strong series is traditionally built on an external hex, while the flagship Unitite uses an indexed Morse taper connection — conceptually closer to the Cone Morse philosophy. There are also lines for different bone densities and immediate-loading protocols.

SIN's surface is a hydrophilic treatment, comparable in purpose to Neodent's Acqua. The practical takeaway for the digital workflow: before planning it's important to identify not only the brand but the specific SIN line and connection type, because external hex and Morse taper require different prosthetic components and, accordingly, different libraries.

Neodent vs SIN implant: Key Differences

If you reduce the comparison to what actually affects the digital workflow, the difference looks like this:

• Distribution: Neodent is a global Straumann Group brand, while SIN is stronger locally in Brazil.
• Connection: Neodent has a unified Grand Morse across all diameters; SIN has separate external hex (Strong) and Morse taper (Unitite).
• Surfaces: Neodent's hydrophilic Acqua and a comparable equivalent from SIN — both for fast osseointegration.
• CAD libraries: a wide set is available for Neodent in exocad and exoplan; coverage for SIN is narrower and needs to be checked.

For the surgeon, the difference in geometry and primary stability may not be decisive — both systems are competitive. But for the technician and whoever plans the surgery in exoplan, the deciding factor is often precisely the availability of a verified library.

Neodent Libraries for exocad and exoplan

For Neodent, the DentalLibs catalog gathers coverage across the entire protocol — from planning to the final restoration. At the prosthetic level this is Neodent Brazil Abutment Level and kits for designing custom abutments and crowns on Ti-Base (titanium base) in in-house, local-milling and centralized scenarios — for example Neodent GM in-house.

For guided surgery in exoplan there are planning libraries marked FDA (Helix GM, Drive GM/CM, Alvim CM Acqua, Facility) and libraries for surgical kits and sleeves: ConeMorse Conical/Titamax kit, EasyGuide, NarrowGM sleeve. The key rule — the planning library and the sleeve library must match the same Neodent surgical kit.

Are There Ready-Made SIN Libraries?

SIN coverage in CAD catalogs is noticeably narrower than Neodent's and depends heavily on the line — Strong or Unitite. Before planning, it's worth checking whether the SIN library you need is in the DentalLibs catalog and, if it isn't available for your platform, discussing a compatible prosthetic component or an alternative workflow. For Neodent this problem usually doesn't arise — the library range covers both planning and prosthetics.
