Instrumental DIR® diagnostics: on the right track with intraoral measurements!

Surveying the patient’s jaw intraorally (DIR: Dynamic Intraoral Registration) using the DIR® System 2 provides the data that dentists need to precisely identify and treat functional disorders. The second component of DIR® functional diagnostics using the DIR® Concept is based on the data collected during this survey using the digital support pin. The DIR® Concept for the treatment of functional disorders (TMD) has been scientifically validated and is utilised according to a self-contained medical history and therapy principle. When recording the patient’s medical history, the dentist focuses on the patient’s “future bite”. The “actual” position of the patient’s jaw or his or her occlusion is surveyed digitally and converted into a “target” position – at the same time determining the optimal physiological positioning of the temporomandibular joint. This new positioning is then achieved using a DIR® bite splint that realigns the masticatory muscles. Once repositioning and treatment have been concluded, occlusion can be reconstructed in the “target” position.

Application: possible indicators

The DIR® System 2 allows dentists to precisely survey the temporomandibular system in order to define functional disorders. The system is used for:

  • Suspected TMD
  • Positioning physiologically optimal occlusion
  • Manufacturing new dental prostheses
  • Orthodontic treatments
  • Patients who have not yet been treated using the DIR® Concept (e.g. with dental prostheses) and now have complaints
  • Bruxism, abraded dentition, noisy joints and other conditions
Quality and reliability

The new DIR® System 2 is a medical device with four components that have been certified pursuant to DIN EN 60601-1 (3. ed.). A dentist who has been trained for DIR® functional diagnostics can rely on the high quality of DIR® medical devices. The DIR® partner laboratory “hires” the components. This means that the dentist enjoys the use of impeccable devices without any financial risk and profits from an easy-to-use, scientifically validated method.

The high quality and reliability of DIR® diagnostics is guaranteed by training events that take place regularly (refresher seminars, obtaining current DIR® quality seals).

Jaw pain, headaches, migraines, neck and shoulder tension, ringing in the ears, tinnitus, temporomandibular problems, pain in the cervical spine, problems in the lumbar spine – all of these symptoms can have one cause: TMD (temporomandibular joint dysfunction). About 8% of all people suffer from what is known as TMD.
Conditions that are due to disorders of form and function in the skull and facial area are referred to as temporomandibular joint dysfunction. Pain does not always have to originate in the place where it hurts. The human being is a unit. This means that the origin of pain is often found somewhere completely different to where the pain itself is felt. It is possible to diagnose the bite. One of our focuses is the functional analysis and therapy of the masticatory system.
