Which country are SIN implants from?

S.I.N. Implant System was founded in 2003 in the Brazilian city of São Paulo and built its entire business around implants: implant bodies, prosthetic parts and surgical kits. The factory shown as its headquarters on the company's own website is also in São Paulo. According to Henry Schein's announcement, SIN's 2022 sales were around 61 million dollars, and the company was focused on developing affordable implants.

Ownership changed in 2023. Henry Schein announced that it had signed a definitive agreement to buy SIN from Southern Cross Group, an independent investment fund focused on Latin America; the price of the deal was not disclosed in the announcement. The acquisition was completed in July 2023. Henry Schein had been serving dentists in Brazil since 2014. SIN joined the company's global oral reconstruction group alongside BioHorizons, Camlog, Biotech Dental and medentis medical.

So the question of which country it is from has a two-layered answer. The product's origin, design and manufacture are Brazilian; the group that owns the company is American. Just like Neodent: it is also a Brazilian manufacturer, and today a brand of the Swiss Straumann group. Two Brazilian brands, two different owners.

These are the main lines listed on SIN's website. Epikut, as the manufacturer describes it, is the line with progressive cutting threads promoted for immediate loading, low-density bone and extraction sockets. Unitite is the line with narrow and short options called Slim and Compact, offered with a hydroxyapatite-coated surface called HAnano. Strong SW, recommended for every bone density with a hybrid design made up of a cylindrical body and a tapered tip, is the family with the widest range of options. Tryon is presented as the classic line; Lite is a simplified option. Zygomatic implants and guided surgery kits are also part of the product range.

The detail to watch with SIN is that the same line is made with more than one connection. Strong SW comes with three separate connections: the conical connection known in Brazil as 'Cone Morse' (CM), the external hex (HE) and the internal hex (HI). Epikut and Tryon come in CM and HE; Lite is offered with an 11.5-degree Cone Morse and an external hex option. So even a card that says 'Strong SW' is incomplete if it does not give the connection letters.

On the surface side, two options stand out: a surface roughened by double acid etching (DAA), and the surface the manufacturer calls 'Plus' or HAnano, which carries a very thin layer of hydroxyapatite. The manufacturer says this surface makes osseointegration easier. Because the same line, with the same connection and a different surface, means two separate product codes, this information should also go on the record.

When looking at the publications, one detail helps. The study published in 2026 comparing the Strong, Unitite and Epikut designs with two surfaces was carried out in the shinbones of 24 rabbits; some of the authors work in SIN's research and development unit, and the company provided the implants and paid the publication fee. This does not invalidate the result, but an animal study and a study with manufacturer involvement should not be given the same weight as independent long-term follow-up in humans. SIN states that it carries out its research together with institutions such as the University of São Paulo, New York University and Chalmers in Sweden.

It is also important to read correctly the policy the manufacturer calls a 'lifetime warranty'. According to SIN's own statement, implants are covered for life and prosthetic parts for five years; but the warranty covers only the replacement of a defective product, and does not cover any service or cost related to treatment. What is more, the policy applies to customers who buy the product directly from SIN or from its authorised distributor; that customer is not the patient but the dentist or clinic that buys the product. The claim is also made by the dentist, who fills in the warranty form and sends evidence such as photos and X-rays.

Even so, the brand is the smaller half of the question. SIN's lines are conventional two-piece implants: they sit in the inner part of the bone and need enough volume there. The implant used in our protocol of fixed teeth in 72 hours with the Ihde method belongs to a different class: a one-piece corticobasal implant that anchors in the hard outer layer of the jaw. Which one suits you is decided by the bone on your CBCT scan.

The criteria below do not depend on the name of the line; they look at the conventional two-piece implant design and can be discussed at your consultation.

They are short questions, but their answers put on record today the information that will be useful to you years from now.

1. 1

   Which line will be used?

   Epikut, Unitite, Strong SW, Tryon or Lite. It should be possible to explain the choice in terms of the density, width and height of your bone.

2. 2

   Is the connection CM, HE or HI?

   Cone Morse, external hex or internal hex. The top parts, and every future repair, depend on this answer; the same line name can refer to three different connections.

3. 3

   Which surface?

   Double acid-etched (DAA), or 'Plus' with a hydroxyapatite layer? They are two separate products of the same line; your card should say which one was used.

4. 4

   Can I see the barcode on the label?

   Medical devices put on the market in Turkey must be registered in the Product Tracking System (ÜTS). The number on the label shows the product's manufacturer and its registration.

5. 5

   Where do parts come from, and how long do they take?

   The manufacturer's website lists Core Medikal as its distributor in Turkey. Ask whether the clinic has parts in stock and, if not, how long it takes to obtain them.

If the first four points below are in place, the difference between brands narrows; if they are not, no brand makes up for the gap.

When a brand is less well known, shortcuts and guesswork multiply online.

Nobody asks for these documents today; but years from now, in another dentist's chair, they will be the first thing you are asked for.

1. An implant card with the line and connection

   The card should say more than just 'SIN': it should give the full description, such as 'Strong SW HE' or 'Epikut CM', together with the surface type, diameter, length and lot number. If anything is missing, ask the clinic that carried out the treatment to complete it.

2. The measured values

   If immediate loading was carried out, the insertion torque and stability values. If a problem is being discussed later, these are the only record showing what the initial anchorage was.

3. A copy of the barcode

   The barcode on the product label carries the number that identifies the implant in ÜTS. When a claim is made under the manufacturer's warranty, this is also the information that proves the product's identity.

4. The X-ray from the first day

   The X-ray that shows where your bone level was at the start. The manufacturer's warranty form also asks for evidence such as X-rays; only with it can a comparison be made with an X-ray taken years later.

The implant's country does not explain the difference in a quote on its own. The total is made up of these items:

Line, connection and surface

Within the same brand, lines and surface options can differ in cost. The quote should give the full description; the phrase 'SIN implant' is not enough on its own.

Top parts

Ready-made parts, patient-specific parts or parts for a multi-unit prosthesis make more difference than the implant body in most plans.

The prosthesis and laboratory work

In full-mouth plans, the material and workmanship of the bridgework make up most of the total. This is the last place where savings should be made.

Preparatory procedures and later maintenance

A graft, a sinus procedure or extractions are separate items. Because the manufacturer's warranty does not cover treatment costs, who covers the work if a problem arises should also be discussed in the quote.
