Which country are Adin implants from?

Adin Dental Implant Systems Ltd. is an Israeli company. The contact page on its own website gives its head office address as the Alon Tavor industrial zone in Afula; the manufacturer's address is the same in the 2023 UniFit submission to the FDA, the US food and drug agency. The company's first record with the FDA dates from 2008; that submission was made through an Israeli medical device consultancy. The contact page lists its subsidiaries in India, the USA and Canada and an office in Tel Aviv.

The sources diverge on the year it was founded. The company's own 'About Us' page says 2001; some start-up databases give an earlier date. Here the company's own statement has been taken as the basis. On the ownership side, Adin presents itself as a company 'on the way to becoming the world's leading independent implant manufacturer'. There is no official announcement of Adin having been sold to a large implant group; its website does not mention a parent company either.

This is why the answer to the question of which country has a single layer: the origin, the head office and the manufacturing address reported to the FDA are all in Israel. The company writes that it has certified its quality system under the European Union's Medical Device Regulation (MDR) and the ISO 13485 standard. Even so, the manufacturer and registration of a single implant that reaches you are shown most definitely by the label and barcode on its box.

Adin is not a single implant but several connection families. The Internal Hex family includes Touareg S and OS, which the company calls its 'most popular', the parallel-bodied Swell and the triple-lead threaded Triple. CloseFit is the family with a conical hex connection; it also includes a narrow 3.0 mm option. UniFit is a newer line that uses a single prosthetic platform across all diameters and has what the manufacturer describes as a 7-degree Morse taper friction-fit connection; it was cleared by the FDA in December 2023. Added to these are zygomatic implants and a guided surgery system called Adinguide.

The detail of the material is as noteworthy as the name of the line. According to the UniFit summary submitted to the FDA, these implants and their top parts are made not of grade 4 pure titanium but of a titanium alloy called Ti-6Al-4V ELI; their surfaces are treated with a calcium phosphate blasting called OsseoFix. The same document writes that immediate loading can be carried out when good initial anchorage is achieved and the bite load is adjusted appropriately, and that the short 6 mm UniFit implants should be used only with straight top parts.

The honest answer to 'how much has it been studied' is this: the Adin name does appear in publications, but most are small or laboratory studies. In a study in which a team from India and Saudi Arabia followed 60 Touareg-S implants in 42 patients for one year, the annual bone loss around implants placed sunk below the bone level was found to be 1.96 mm on average, and 1.10 mm for those placed at bone level. In other words, the same brand, the same line, the same team: deeper placement was seen together with more bone loss. The study is small and it is not stated that the groups were allocated at random; but it shows well that the surgery speaks before the brand does.

In another study, carried out in India, three surgeons placed 45 Touareg implants in 42 patients with a hand wrench that does not measure torque; when it was checked at the final moment with a wrench that does measure, the mean torque applied turned out to be 63 Ncm, well above the 35 Ncm that was intended. The study did not measure whether this torque harmed the implant. But it does show this: insertion torque should be applied by measuring, not by guesswork, and should be put on record. Long-term, large patient follow-ups carried out with Adin, meanwhile, are limited.

Adin's lines are conventional two-piece implants that sit inside the bone, and they need sufficient volume in the bone; the zygomatic implants, however, are a special group that anchors in the cheekbone. The outcome is determined by planning, how the load is spread, smoking and diabetes control and regular maintenance more than by the brand name. 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.

The points below are not specific to Adin alone; they look at the two-piece implant design that sits inside the bone.

They are short questions. If the answers are clear, there is a considered choice behind the plan; every answer that stays vague is a gap you will have to fill in later.

1. 1

   Which family and which line?

   Touareg, Swell or Triple from the Internal Hex family; CloseFit; or UniFit? It should be possible to explain the choice in terms of the density, width and height of your bone.

2. 2

   How deep will the implant be placed?

   At bone level or below it? In a small study carried out with Touareg-S, more bone loss was seen over one year in implants placed below the bone level. Asking for the reason is a normal request.

3. 3

   Will the insertion torque be measured?

   You can ask for the torque applied with a measuring device and, if there is one, the stability measurement to be written into your record. The decision on immediate loading should be based on these values.

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

   What does the manufacturer's warranty cover?

   Adin announces a lifetime replacement warranty for the implants it manufactures. That text is about the implant itself; ask the clinic separately who will cover new surgery, labour or renewal of the prosthesis.

The studies carried out with Adin are consistent with this too: within the same brand, the outcome can differ according to surgical decisions.

Several line names and Israel's crowded implant sector produce a few misleading shortcuts 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 family and the line

   The card should say more than just 'Adin': it should give the Internal Hex, CloseFit or UniFit family, the line name, the platform, the diameter, the length and the lot number. If anything is missing, ask the clinic that carried out the treatment to complete it.

2. The measured values

   The insertion torque and, if there is one, the stability measurement. 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. If the manufacturer's warranty comes up, this is also the first piece of information that will be asked for.

4. The X-ray from the first day

   The X-ray that shows where the bone level and the depth of the implant were at the start. Only with it can any change be read when it is compared with an X-ray taken years later.

Adin positions itself as an affordable manufacturer; but the name of the implant does not determine the difference in a quote on its own. The total is made up of these items:

Choice of line and body

Within the same brand, the families and lines can differ in cost. Check which line is written in the quote; the phrase 'Adin implant' is not enough on its own.

Top parts and the prosthesis

Ready-made parts, patient-specific production or parts for a multi-unit prosthesis, together with the material and workmanship of the bridgework, make up most of the total in full-mouth plans.

Preparatory procedures

If a graft, a sinus procedure or extractions are needed, these are separate items and are common in conventional plans. They also lengthen the treatment.

The scope of the warranty and repairs over the years

What the manufacturer replaces is the implant itself; labour and retreatment are discussed separately. With a system whose parts are easy to find, a repair stays a small job.
