Occlusion (dentistry)

The occlusion ( closing, closure ) is any contact between the teeth of the upper jaw and the lower jaw. The contact points are on the occlusal plane that is not flat but curved in the sagittal and transversal (fachsprachlich wound ) is. Accessible, but not accepted by the professional associations is the view occlusion was only the final occlusal position, so the maximum intercuspal position (Latin cuspis, the hump ').

It differs in detail:

  • Static occlusion: tooth contacts without movement of the mandible
  • Maximum intercuspal: is the lower jaw posture, is at the maximum multi-point contact between the mandibular and maxillary teeth. Static occlusion with maximum multi-point contact
  • Habitual occlusion: Habitually occupied static occlusion
  • Centric Occlusion: Maximum intercuspal position in centric condylar position ( condyle is in this case, the condyle of the jaw joint )

Definitions

The German Society of Dental, Oral and Maxillofacial Surgery ( DGZMK ) defined types of occlusion as follows:

  • Occlusion: Any contact between the teeth of the maxilla and mandible.
  • Static occlusion (English static occlusion ): tooth contacts without movement of the mandible in intercuspal position.
  • Dynamic occlusion (german dental articulation, and dynamic occlusion ): tooth contacts that occur as a result of movement of the mandible.
  • Habitual occlusion: Habitually occupied static occlusion
  • Centric occlusion (English centric occlusion ): Static occlusion in centric condylar position.
  • Anterior guidance (English incisal guidance ): dynamic occlusion between the upper and lower anterior teeth
  • Canine (English canine guidance, also cuspid guidance, canine rise ): dynamic occlusion between upper and Unterkiefereckzähnen.
  • Group leadership (English group function): dynamic occlusion between several teeth on the Laterotrusionsseite.
  • Occlusion (English occlusal concepts ): Front Tooth-supported occlusion ( engl. anterior protected articulation ) occlusion with anterior guidance that leads to disclusion all the other teeth.
  • Cuspid occlusion ( engl. canine - protected articulation ): occlusion with canine guidance that leads to disclusion all the other teeth.
  • Unilateral guided occlusion (german group function): Occlusion with keeping the teeth of Laterotrusionsseite that leads to disclusion all other teeth (see group leaders ).
  • Bilateral guided occlusion (bilateral balanced occlusion; well balanced articulation ): occlusion with keeping the teeth to laterotrusion and mediotrusion ( balanced occlusion ).
  • Occlusion (English occlusal disturbances )
  • Nonocclusion (English nonocclusion ): Missing antagonists contact with existing dentition.
  • Pre-contact (also early contact) (English deflective occlusal contact): Premature contact of a tooth or a group of teeth in static / dynamic occlusion
  • Centric Precontact (English defflective occlusal contact): Premature contact of a tooth or a group of teeth in centric condylar position, of the condyle results in oral habitual occlusion in an eccentric position.
  • Traumatic occlusion (English Traumatogenic occlusion ): premature contacts in static and / or dynamic occlusion, leading to damage to the tooth and / or the periodontium.
