| Question | Answer |
| Anterior Guidance | The influence of the contacting surfaces of teeth on mandibular movement |
| Arcon (Articulated Condyle) | Where the condyle part is attached to the lower member of the articulator. Non-arcon is where the condyle part is attached to the upper member of the articulator |
| Articulation | A dynamic relationship of the upper and lower teeth which exists during mandibular movement from one occlusion to another |
| Balanced Articulation (Fully Balanced Occlusion, Balanced Dynamic Occlusion) | A multi-point contact relationship of the opposing teeth in which they guide smoothly over each other during mandibular movement without causing dislodgement of the dentures |
| Balanced Occlusion (Bilaterally Balanced Occlusion, Balanced Static Occlusion) | A multi-point contact relationship of opposing teeth in static contact |
| Bennett Angle (Progressive Side Shift) | The angle obtained after the non-working side condyle has moved anteriorly and medially, relative to the sagittal plane. The flatter the cusp the greater the side shift. |
| Bennett Shift (Bennett Movement, Immediate Side Shift, Mandibular Side Shift) | The bodily lateral movement of the mandible towards the working side during lateral excursions |
| Bruxism (Parafunctional Activity) | Tooth contacting habits, which are not necessary in order to execute the normal physiological oral function (clenching and grinding). |
| Canine Guidance (Canine Protected Occlusion) | The part of anterior guidance that often occurs on lateral excursion, where the mandibular movement is dictated by mandibular canine-maxillary canine contacts |
| Centric Occlusion (Intercuspal Position, Habitual Occlusion, Intercuspation Position, Maximum Intercuspation, Habitual Centric, Aquired Centric, Bite of Accomodation) | The position of the mandible when the maxillary and mandibular teeth are at their most interdigitated |
| Centric Related Occlusion | When CO and CRO are co-incidental. This is the ideal that we aim for in an equilibrated mouth. Simultaneous contact of all teeth with the condyles in centric relation. |
| Centric Relation Occlusion (CRO) (Retruded Contact Position) | The position of the mandible determined by tooth to tooth contact when the mandible closes in CR |
| Centric Relationship (Terminal Hinge Axis, Terminal Hinge Relation, Retruded Arch of Closure, Retruded Axis Position, Ligamentous Position, Hinge Axis) | The most retruded position of the mandible relative to the maxilla dtermined by the TMJ with the teeth separated. Condyles in the upper most position in fossa. |
| Centric Stop (Centric Stop Position) | Cusp tip used to achieve contact |
| Condyle | The rounded surface at the distal extremity of the ramus of the mandible, which fits into the Glenoid fossa to form the tempromandibular joint |
| Condylar Angle (Condyle Path) | The angle given by the downward and forward slope of the glenoid fossa. |
| Condylar Guidance (Angle of Eminencia) | The mechanism on an articulator which reproduces the paths down which the condyles travel on protrusion of the mandible. |
| Conformative | When restorations are fabricated to the existing jaw relationship |
| Crossover Interferences | Once the canine has moved into a position that is labial to the upper canine and the tips have crossed over, the mandible has then entered the crossover position |
| Disclusion (Discluding) | The separation of teeth during excursive movements |
| Fossae (Fossa) | A depression |
| Freeway Space (Interocclusal clearance, Interocclusal Space) | The space between the occlusal surfaces of the maxillary and mandibular teeth when in the rest position. |
| Functional Cusp | The palatal cusps of maxillary teeth and buccal cusps of mandibular teeth which occlude with opposing fossae |
| Group Function (Shared Function) | Guidance of the mandible when a number of posterior teeth are in contact in lateral and protrusive excursion |
| Interference (Occlusal Interference, Deflective Contacts) | An uneven, early contact arising on one or more teeth during an excursive movement causing disclusion of guiding teeth |
| Intercondyler Distance | The distance between the condylar heads at any point |
| Lateral Excursion (Latrusion) | Sideways movement of the mandible |
| Lingualized Occlusion (Palatalised Occlusion) | Where only the maxillary posterior palatal cusps occlude with shallow mandibular central fossae |
| Long Centric (Freedom in Centric Occlusion) | Freedom of the mandible to slide forward at the same vertical dimension |
| Malocclusion | A deviation from normal occlusion of one or more teeth in the dental arches |
| Mutually Protected Occlusion (MPO) | That in centric relation there is only posterior tooth contact |
| Non-Working Condyle (Orbiting Condyle) | The condyle on the non-working side, which undergoes a mainly translatory movement during function on the working side |
| Non-Working Movement (Non-Working Side, Non-Functioning, Balancing, Contralateral, Orbiting Side) | The side the mandible is moving away from |
| Non-Working Side Interferences | A Posterior contact on the non-working side which interferes with ideal anterior guidance |
| Pantographic Reading | A reading from a device that accurately traces mandibular movements with two main component parts |
| Path of Closure (Line of Closure) | The path taken from rest to occlusal positions. Usually traced at the incisal edges of the lower central incisors. |
| Premature Contact (Closure Interference, First Point of Contact) | An uneven contact arising only on one tooth as the mandible closes to centric occlusion |
| Proprioceptive | The sensory perception of the occlusal load due to the periodontal ligament that attaches the teeth to the alveolus |
| Protrusive Excursion (Protrusion) | Forward movement of the mandible |
| Reorganised | When restorations are fabricated to the patients jaw position in centric relation |
| Rest Position (Postural Rest Position, Postural Position) | The position the mandible adopts when standing or sitting upright, when the musculature is at rest |
| Sagital Plane | The longitudinal vertical plane that divides the mouth into two halves |
| The Alert Feeding Position | The head is tilted 30 degrees forward. The aim is to have no deflective contacts on the maxillary anterior teeth as the mandible closes in its acquired position. |
| Working Condyle | The condyle on the working side |
| Working Movement (Working Side, Functioning Side, Rotating Side) | The side the mandible is moving to during excursive movement |
| Working Side Interferences | A posterior contact on the working side which interferes with the ideal anterior guidance |
