The manual clinical functional analysis

The manual clinical functional analysis is used to record the functional findings in the craniomandibular system, as functional disorders are often not correctly recognized without a professional analysis.

This makes it all the more important to have a basis for safe and rapid functional diagnostics in the dental practice, which should be used as a matter of course for every patient before restorative and/or orthodontic treatment planning and to differentiate between unclear jaw and facial pain and/or orofacial dysfunctions.

What does a practical method look like?

Since different causes of the complaints require different treatment approaches, a targeted and thorough diagnosis is of the utmost importance before starting treatment.

1. which diagnostic concept will get me to the desired goal?

2. what does professional functional prophylaxis look like in the practice?

3. do I need further diagnostic measures?

4 Which examinations will give me a clear and unambiguous diagnosis?

5 How can I bill for functional diagnostics?

It should not only consist of a subjective medical history, but must also include a clinical functional status. This is the only way to make a reliable diagnosis that includes all important clues. This would then fulfill the dentist’s obligation to perform a clinical functional analysis as a basic examination. Such an analysis could serve as a well-documented decision-making basis for a possible course of treatment.

The basic examination is always in the foreground.

During CMD screening (basic CMD diagnostics), the patient undergoes a general dental anamnesis with an individually completed digital questionnaire and brief dental findings. If there is no suspicion of a functional disorder, the functional analysis can be completed with this.

If there are indications of a functional disorder, such as

-Tension headaches, migraines, tension in the back and neck muscles, pain in the jaw joints, tinnitus, dizziness, etc.

the dental check is deepened.

The manual clinical functional analysis is used to differentiate between pain, restrictions, disorders of the stomatognathic system, joint noises and different disc displacements. It provides comprehensive results that are documented and evaluated in order to make an initial diagnosis and plan the further course of treatment.

Even if private reimbursement agencies like to refuse to cover the analogous CMD screening service or do not readily recognize the medical necessity of the service, it should not be dispensed with in view of the current case law on dental liability.

These questions and requirements have prompted dentists with their own practices and specialist consultants, together with the Society for Functional Diagnostics, to develop the functional prophylaxis procedure for all dentists in a practical and professional manner. The result is the easy-to-use FunktioCheck Pro® software.

The FunktioCheck Pro® software enables you to carry out a quick and uncomplicated manual anamnesis and to make a reliable diagnosis based on the structured entries.

The DIR® concept

Diagnostics

As part of the DIR® concept, the FunktioCheck Pro® software documents the preliminary dental findings.

The type of complaints and previous visits to the dentist from other specialist disciplines are recorded as part of the functional dental history. In the brief dental findings, missing canine guidance, non-age-appropriate abrasion of the teeth in the sense of grinding facets and abrasions or The brief dental findings record missing canine guidance in the sense of grinding facets and abrasions or wedge-shaped incisions, tooth loosening, tilting and migration, gingival recessions with Still-man clefts and McCall’s garlands, pain during muscle palpation, temporomandibular joint noises as well as restrictions and asymmetrical mouth opening movements, resulting in a three-grade probability statement for the presence of a functional disorder and a recommendation for further findings.

The special functional analysis carried out in the case of a high probability of CMD, the so-called Axis 2 diagnostics, is highly relevant for the success of the subsequent therapy and is objectively assessed using a Graded Chronic Pain Scale and a pain perception scale, whereby an evaluation of the patient’s degree of psychological stress is possible in an evaluation form.

The subsequent manual-clinical diagnostics allow an assessment of a manifest arthropathy with examination of the temporomandibular joint function to exclude or confirm the presence of a disc perforation or a disc displacement, condylar osteoarthrosis, hypermobility, capsulitis or inflammation of the bilaminar zone. The morphological or structural remodeling processes in the hard tissues should of course be confirmed radiologically (MRI). Manifest myopathy is assessed by performing standardized masticatory muscle examinations using the isometric tension test and muscle palpation.


The manual functional analysis is followed by the instrumental functional analysis with the DIR® system, which is also carried out on functionally healthy patients as part of prosthetic planning. The electronic measuring method is based on the arrow angle or support pin registration according to Gerber with recording of the marginal movements of the mandible under physiological masticatory pressure and without reference to occlusion.

Centric position as target bite

Once the DIR® measurement has been completed, the centric position determined is encoded in the patient’s mouth as a so-called target bite by guiding the support pin into a fixation plate under defined chewing pressure. This is followed by transfer to the articulator. In the following model analysis, an occlusion analysis is performed, whereby the deviation of the habitual occlusion or the current actual state from the centric occlusion or the target bite is documented.
