About VieSID

 VieSID, short for the Vienna School of Interdisciplinary Dentistry, originated in Austria as an evolution of the teachings of Prof. Dr. Rudolf Slavicek, the past Dean of the University of Vienna and the director of postgraduate training for dentists at the Danube (Donau) University in Krems, Austria. VieSID offers postgraduate training for dentists and dental technicians and is organized in cooperation with the Medical University of Vienna and the University Dental Clinic in Vienna. The cooperation with the Medical University of Vienna also includes the support of scientific research on the subjects of occlusion and function in dentistry.

Goal of VieSID
Goal of VieSID
The goal of the Vienna School of Interdisciplinary Dentistry is to teach the knowledge and concepts of Professor Dr. Rudolf Slavicek. Additional training in other concepts including those of Professor Sadao Sato (Orthodontics) makes this program truly interdisciplinary. VieSID cooperates with independent renowned international experts and lecturers and is responsible for the content and organization of the curricula. In addition to Vienna, VieSID programs are taught worldwide. Professor Rudolf Slavicek’s teaching spreads from Latin America to Canada, other European countries, Russia and China.
Education in Occlusal Medicine
Education in Occlusal Medicine
The VieSID basic curriculum is designed to provide participants with an in depth understanding of structural development and the functional requirements of the masticatory system. Emphasis is placed on the clinical skills and instrumentation required to achieve optimal diagnostic success in everyday practice.The Basic Curriculum is designed for dentists and their dental technicians who are looking for a program that provides a logical concept for occlusal rehabilitation that can be tailored to the individual patient. We have designed this extensive curriculum to be the most comprehensive course in occlusion available today.
Clinical Instrumental Analysis
Clinical Instrumental Analysis
Clinical Instrumental Analysis is a proven part of the diagnostic approach in interdisciplinary dentistry. Instrumentation provides additional information which is critical to a complete diagnosis. The instrumentation taught includes semi and fully adjustable articulation, anatomic and kinematic facebow, MPV, CPM and Electronic Condylography. Condylography is a non-invasive method of monitoring the patient’s individual movements of their mandible within 6 degrees of freedom. At the centre of of these studies are the translational and rotational components of hinge-axis movement of the mandible. These movements are related to a standardized craniomandibular coordinate system (hinge-axis-orbital coordinate system) based on a zero starting point called Reference Point (RP)Condylography recordings are useful to program condylar housings of semi- and fully-adjustable articulators according to the patient-individual movement patterns. The data may also be used to judge the mobility and motility of the TMJs. Based on standardized border movements (Protrusion, Mediotrusion right and left and Open/Close) preliminary assessment of the functional status can be performed. Functional movements (Bruxing, Speech, Swallow, etc.) can be analyzed and integrated where indicated into the treatment planning.

How do we teach?

The theoretical lessons are taught in classroom style. Numerous hands-on exercises are taught in both the clinic and laboratory. Homework and both written and oral evaluations give teachers and students feedback on the educational experience as each module is completed. Our small class size allows for a very interactive learning experience with the other students and teachers. Student case presentations complete the training and provide a comprehensive learning experience. For a description of “what we teach”, see curriculum.

With the support of the team of Prof. Rudolf Slavicek all participants will perform diagnosis, documentation and case planning for selected patient cases.

The basic curriculum program is the fundamental primary course for dentists and dental technicians who are seeking further education in Occlusal Medicine. The course topics include thorough training in function and dysfunction of the craniofacial system, based on the teachings of Prof. Rudolf Slavicek and his Vienna School of Interdisciplinary Dentistry. This intensive and comprehensive course offers a curriculum including theory and practical hands-on exercises individually designed for dentists and for dental technicians. The program is divided into three five-day modules at intervals allowing prescribed homework that allows attendees to practice the concepts learned. This system allows our students to rapidly implement the acquired knowledge immediately into their daily practice.

The duration of the course is 15 days, split into 3 modules of 5 days.  All modules are from Thursday to Monday, to minimize time away from the dental practice.  Homework will be prescribed which is completed between modules allowing all participants to gradually implement procedures into their daily practice. Case presentation is an essential part of the basic curriculum and a requirement for graduation. Each student is required to submit three fully documented cases. GAMMA DENTAL in Austria will provide each participant with a trial license for Gamma’s CADIAX and CADIAS software so that you will be able to use the GAMMA document browser to organize your diagnostic data. This license is valid for the duration of the course.

VieSID provides all hand out material and necessary equipment for use during the course sessions, and a trial subscription to CADIAX/CADIAS software which will last for the length of the program. If you wish to purchase any equipment for your practice we will assist you with it. If you would like to research the equipment available please visit GAMMA DENTAL PRODUCTS on our website. Prior to the beginning of module A all course participants will be asked to have two sets of upper and lower accurate casts fabricated with both upper casts split casted and one lower pinned. Details will be provided. During the course days we will supply enough GAMMA Reference articulators, access to electronic condylography units, hinge axis transfer jigs, CPM’s, sundries and any other supplies necessary to complete the diagnosis. Initially participants will practice in pairs with fellow attendees to learn the procedures. After successfully passing an examination at the end of the Module C participants receive an official diploma which is necessary to attend advanced VieSID programs in Prosthodontics and Orthodontics. Organised by: VieSIDBulgaria®, in accordance with the program VieSID teaches in Vienna in cooperation with the Medical University of Vienna and the University Clinic of Dentistry Vienna.

The articulator is a device used for simulating jaw movements. Plaster models of the upper and the lower jaw are mounted to the articulator to simulate the natural chewing movements and the dental status, so that he dentist can identify occlusal problems and can initiate the necessary treatment steps for a perfect function of the masticatory organ.
The use of an articulator is especially necessary for making partial or complete dentures and during functional analysis.


Axiography means recording of movement traces of the lower jaw respectively the condyles (hinge axis). See Condylography

Bite splint (occlusal splint)

The bite splint is an individually adjusted, removable and temporary synthetic splint which is used for a lack of contact between the chewing surfaces of the jaws. Bite splints mostly are applied to the lower jaw. The aim of the bite splint therapy is the elimination and relief of wrong or overload of the teeth or jaw joints.


Bruxism is the grinding of teeth or clenching of teeth. It usually occurs unconsciously at night while sleeping or during the day. The main causes of bruxism are psychological and emotional stress and tension, but triggers can also be sleep-related breathing disorders, nicotine, alcohol consumption or medication. This overload can lead to destruction of the hard tooth substance, which will make the teeth sensitive to pain. Bruxism can be diagnosed with the help of the BruxChecker, a simple diagnostic tool. The result is an overload of the teeth, the tooth holder and / or excessive wear and damage to the tooth structure. These processes can make your teeth sensitive and painful. A gnash splint can help

Bennett – movement

(Bennet, London Oral Surgeon, 1870-1947); this means lateral, spatial displacement of the lower jaw during lateral movement (so-called lateral movement or laterotrusion). The laterotursion condyle is laterally displaced during a laterotrusion movement. The temporomandibular joint head (condyle) on the laterotrusion side (“working joint”, “working condyle”, functional joint, “resting condyle”, see illustration) can – due to the anatomy of the temporomandibular joint – experience the following movements: to the side and to the front = lateroprotrusion to the side and back = latero retrusion to the side and up = laterostrusion to the side and down = laterodetrusion This Bennett movement can start immediately and at the same time at the beginning of the sideways movement.

Bennett angle

Mediotrusion angle, angle between the pro and mediotrusion path of the vibrating condyle, projected onto the horizontal plane (= horizontal mediotrusion path), English: Bennett’s angle; (London oral surgeon Bennet, 1870-1947). This angle, which is described as “difficult” by definition, is based on a peculiarity of the temporomandibular joint during the chewing act: In the case of pure feed movements, the two condyle centers describe, among other things, a uniform path running in the ventral direction (towards the abdomen). With a sideways movement (laterotrusion, eg for chewing) the condyle on the mediotrusion side (“balance side”) moves ventrally and medially (so-called swinging condyle). The other condyle is the movement center (work side, so-called resting condyle) the movement center. The Bennet angle is now the angle measured on a horizontal plane between the recording of a pure feed movement in the sagittal direction (protrusion movement) and a lateral (lateral) movement of the “oscillating condyle” on the balance side. The path of this condyle is described by a straight line that connects the beginning and end of the condyle path recording. This angle is approximately 10 – 15 degrees on average. (Source: that connects the beginning and end of the condyle path recording. This angle is approximately 10 – 15 degrees on average.

Condylography is necessary for the extensive diagnosis and diagnosis of craniomandibular dysfunctions. In condylography, the movements of the temporomandibular joints are recorded three-dimensionally.


three-dimensional motion of the condyle in the skull-related coordinate system with division into: horizontal condylar : movement path of the condyle to the horizontal plane projected frontal condylar : movement path of the condyle on the frontal plane.

Condylar position (centric)

Term for the position of the temporomandibular heads in the terminal, that is, the most distant hinge axis position. The TMJ heads are located in the zenith of the joint pit.


mandible, condyle, capitulum mandibulae, joint head, joint head, temporomandibular joint head, movable, roller-shaped part of the temporomandibular joint, which sits at the tip of the condylar process of the lower jaw. Articulates directly with the intermediate disc (disc) and indirectly with the socket (fossa mandibularis). When subjected to violence, its approach to the lower jaw (collum mandibulae) is one of the fragile parts of the lower jaw (“collum fracture”). A “swinging condyle” means the joint head on the balance side; the “resting condyle” is that of the working side (Bennet angle, mediotrusion side (source:

CMD (craniomandibular dysfunction)

(Dysfunction; cranio = derived word part for skull or head, mandibular = lower jaw),

Malfunction in the area of all structures that determine and control the position of the lower jaw to the upper jaw; Collective name for a diverse complex of diseases of the chewing system that relate to symptoms in the head and neck area, such as:

  • migraine-like possibly chronic headache
  • Trigeminal pain / facial pain
  • Pain and / or tension in the area of the neck and shoulder girdle muscles
  • stiff neck
  • Myalgia in the entire course of the back muscles
  • Disc problems
  • Static problems in the loin, hips or knees
  • Competitive athletes prone to injury

    In addition to clinical and instrumental functional analysis, imaging methods (based on X-ray technology, magnetic resonance methods, ultrasound methods (sonography), endoscopic methods (arthroscopy)) and consultative methods (for clarifying psychological and orthopedic factors (especially the cervical spine)) are used for diagnosis.
    Two therapeutic approaches are under discussion: a somatic and a psychological. The somatic approach focuses on changes in occlusion, splint therapy, medication and surgical measures, the psychological approach focuses on home exercises, stress management, education, biofeedback, hypnosis and behavioural therapy. In a controlled, randomized study (Journal of Orofacial Orthopaedics / Progress in Orthodontics, 04/2002: 259-260), 124 patients with CMD between 18 and 70 years were divided into two groups. One half was treated with patient education, physiotherapy, splint therapy and medication, the other with three three-hour information sessions, instructions for stress management, relaxation procedures and an individually developed home exercise program. The success of the therapies was compared after six weeks and six and twelve months. It was shown that the patients from the home exercise group performed significantly better in almost all parameters at all times. (Source:

Craniomandibular system

The Craniomandibular System (CMS) encompasses all organs, muscles and nerves of the head and shoulder area that work closely together. Incorrect strain on the masticatory muscles and the temporomandibular joints, but also incorrect posture of the support and holding apparatus can lead to painful symptoms.

Organs of the head and shoulders:

  • Tooth retention device (periodontium)
  • Chewing organ (teeth, temporomandibular joints, chewing muscles)
  • Swallowing organs (swallowing muscles)
  • Speech organs (speech muscles)
  • Facial expressions and contact organs (facial muscles)
  • Hearing organs (ears)
  • Visual organs (eyes)


Dysgnathia is a summary of the malformations of the teeth, jaws and / or the chewing system. The anomalies can affect the position of the teeth, the teeth, the shape of the jaw, the position of the jaws in relation to each other or the installation of the jaws in the skull and, as a result, can cause aesthetic and functional impairments

Functional analysis / functional dentition analysis

Examination to determine or exclude malfunctions in the chewing organ


Teaching of the jaw, in particular its functions; Treatments from a gnathological point of view take into account the teeth, but also the structures surrounding them, the muscles, ligaments and bony parts, such as the temporomandibular joint. The structures and functions are examined. (Source:


If the teeth are not correctly connected to each other, the lower jaw automatically shifts to a new position when closing to compensate for the misalignment of the teeth. This results in the state of malocclusion.


The contact of the teeth of the upper jaw with those of the lower jaw. The contact points form the occlusal plane.

A distinction is made between: Static occlusion – tooth contacts without movement of the lower jaw. The static occlusion is divided into habitual, centric and maximum occlusion. Dynamic occlusion – tooth contacts that result from movement of the lower jaw. The dynamic occlusion is divided into anterior guidance, canine guidance and group guidance


The field of dentistry that deals with the treatment of misaligned teeth.

Temporomandibular joint

The human temporomandibular joint lies in a hollow at the base of the skull just in front of the bony ear canal. It is a rotating sliding joint that is surrounded by a joint capsule. The temporomandibular joint is the only joint in the body that can move in 3 axial directions. (Source:
