IPS Implants® TMJ Prosthesis

Innovative Solutions x Established Workflow

The temporomandibular joint is a unique joint in the human body due to the complexity of its geometry, function, the structures involved and the influences acting on it. However, this makes it susceptible to functional disorders and diseases.

With IPS Implants® TMJ Prosthesis, we are expanding our IPS Implants® portfolio with a temporomandibular joint prosthesis. Its innovative design is based on anatomical movement sequences and enables the patient to open and close the mouth. IPS Implants® TMJ Prosthesis also impresses with the workflow around our custom-made implants, which has been established over several years.

Postoperative reconstruction of movement through anatomically oriented fossa and condyle design

Postoperative reconstruction of movement through anatomically oriented fossa and condyle design

Previous prostheses were mostly based on the ball-and-socket principle, but this means that the complex movement apparatus of the mandible cannot be fully reproduced.

For this reason, we have adapted our condylar fossa design in that way that it corresponds more closely to the anatomical features of the more oval-shaped condyle. This allows the patient to perform all the necessary movements: opening and closing the mouth.

Flexible design for individual needs

Flexible design for individual needs

Thanks to the custom-made properties of our IPS® products, we can offer each customer a prosthesis which is optimally tailored to their specific requirements, individual characteristics, and the patient's situation.

Mechanical safety with IPS inSilico® x VIT

Mechanical safety with IPS inSilico® x VIT

All dentures are checked and approved before production using finite element analysis (FEA). This offers you a wide range of designs. Each custom-made prosthesis is simulated using finite element analysis (FEA), evaluated for mechanical safety, and approved.

Fields of application

Reconstruction via IPS Implants® TMJ Prosthesis is indicated for patients with severe temporomandibular joint disorders, which may be associated with functional limitations of the masticatory system, restricted jaw opening or pain in the temporomandibular joint, for example.

FAQs

IPS Implants® TMJ Prosthesis

1. Which products are included in an IPS Implants® TMJ Prosthesis case?

The following customized products are included in a package:

  • Fossa component 
  • Condyle component 
  • Models of the mandible and maxilla
  • Guides for condyle and fossa
  • Planning aids as prosthesis replica for preparing the soft tissue

Alternatively, additional guides, models or planning aids can be offered.

2. Does IPS Implants® TMJ Prosthesis contain cobalt-chrome?

No. Most TMJ prosthesis suppliers work with a material combination that contains cobalt-chrome. This causes allergic reactions in many patients.

We have deliberately decided against cobalt-chrome. Our metal parts of the prosthesis components are made of additively manufactured titanium alloy Ti6AM4V.

3. Is it possible to obtain the STLs of the final planning data?

Yes, we would like to offer you an all-around service that allows you to use the STLs for preoperative visualizations, intraoperative navigation, or postoperative analyses.

4. Can an IPS Implants® TMJ prosthesis be connected to a mandibular reconstruction plate?

Yes, since we design and manufacture both mandibular reconstruction plates and the prosthesis in-house, such combinations are no problem for us.

5. Can an IPS Implants® TMJ prosthesis be combined with orthognathic planning?

Yes, since we design and manufacture both plates for orthognathic procedures and the prosthesis in-house, such combinations are not a problem for us.

6. Can only a separate custom-made fossa be ordered and combined with an off-the-shelf temporary condylar implant?

No. The IPS Implants® TMJ Prosthesis is a total prosthesis.

The temporary condylar implant from our standard/off-the-shelf portfolio is only a short-term bridging solution (max. 2 years) and cannot be combined with the IPS® variant.

Required osteosynthesis accessories

The following osteosynthesis accessories in sterile condition are required for the surgical treatment of IPS Implants® TMJ Prosthesis:

  • Sufficient number of KLS Martin osteosynthesis screws in the planned diameters and lengths
  • A screwdriver suitable for the planned osteosynthesis screws
  • Suitable drills for the planned osteosynthesis screws

Legal basis for IPS Implants®

According to the regulation (EU) 2017/745, a custom-made product is a device specifically made in accordance with a written prescription of any person authorized by national law by virtue of that person's professional qualifications which gives, under that person's responsibility, specific design characteristics, and is intended for the sole use of a particular patient exclusively to meet their individual conditions and needs.

For this reason a separate inquiry is necessary in every IPS® case.

The written prescription is a release for the technical offer (design of the products). This is to be submitted in writing by the user at the same time as the required order for the economic offer if he/she agrees with the desired case planning.

Shipment is not permissible as a matter of principle without this mandatory regulatory document.
