Occlusion (dentistry)

from Wikipedia, the free encyclopedia

The occlusion (occlusion, shutter) is any contact between the teeth of the upper jaw and the lower jaw . The contact points lie on the occlusal plane , which is not flat, but rather curved in the sagittal ( Spee curve ) and transversal ( Wilson curve ) (technically: twisted ). Common, but no longer accepted by professional societies, is the view that occlusion is only the final bite position, i.e. the maximum intercuspation ( Latin cuspis , the cusp ).

Centric occlusion (view from dorsal [from back to front] on the rows of teeth)

One differentiates in detail:

  • Static occlusion: Tooth contacts without movement of the lower jaw
  • Maximum intercuspation: Lower jaw posture in which there is maximum multi-point contact between the lower and upper teeth. Static occlusion with maximum multi-point contact
  • Habitual occlusion: Habitually adopted static occlusion
  • Centric occlusion: maximum intercuspation with centric condylar position ( in this case the condyle is the joint head of the temporomandibular joint)

Definitions

Canine guidance

The German Society for Dentistry, Oral and Maxillofacial Medicine (DGZMK) defines types of occlusion as follows:

  • Occlusion: Any contact between the teeth of the upper and lower jaw .
  • Static occlusion ( English static occlusion ): Tooth contacts without movement of the lower jaw in maximum intercuspation .
  • Dynamic occlusion (English dental articulation , also dynamic occlusion ): Tooth contacts that arise as a result of movement of the lower jaw .
  • Habitual occlusion: Habitually adopted static occlusion
  • Centric (Engl. Occlusion centric occlusion ): static occlusion in centric condylar position .
  • Anterior guide (engl. Incisal guidance dynamic occlusion between:) upper and lower jaw incisors
  • Canine (engl. Canine guidance ; also cuspid guidance , canine rise ): dynamic occlusion between the upper and lower jaw canines .
  • Group function : dynamic occlusion between several teeth on the laterotrusion side .
  • Occlusion (Engl. Occlusal concepts ): Anterior-based occlusion (. English anterior protected articulation ) -Okklusionskonzept with front tooth guidance, to disclusion leads all other teeth.
  • Cuspid occlusion (Engl. Canine-protected articulation ): occlusion with canine guidance needed to disclusion leads all other teeth.
  • Unilateral guided (engl. Occlusion group function ): occlusion with guidance of the teeth of the Laterotrusionsseite that for disclusion leads all the other teeth (see group management).
  • Bilaterally guided occlusion (bilateral balanced occlusion; also balanced articulation): occlusion concept with guidance of the teeth to the laterotrusion and mediotrusion side (balanced occlusion).
  • Occlusal (. English occlusal disturbances ), which include:
    • Nonocclusion : Lack of antagonist contact with existing teeth.
    • Pre-contact (also early contact) (English deflective occlusal contact ): Premature contact of a tooth or a group of teeth in static / dynamic occlusion
    • Centric pre-contact ( defflective occlusal contact ): Premature contact of a tooth or a group of teeth in a centric condylar position, which moves the condyle into an eccentric position when the habitual occlusion is assumed .
    • Traumatizing occlusion (Engl. Traumatogenic occlusion ): Pre-contacts in static and / or dynamic occlusion, which lead to damage to the tooth and / or the periodontium.
