Arbitrary facebow
A device used to relate the maxillary cast to the condylar elements of an articulator using average anatomic landmarks to estimate the position of the
Arcon Articulator
An articulator that applies the arcon design; this instrument maintains anatomic guidelines by the use of condylar analogues in the mandibular element and fossae assemblies
Articular capsule
The fibrous ligament that encloses a joint and limits its motion. It is lined with the synovial membrane (GPT8).
Articular disc
A ring of fibrocartilage that separates the articular surfaces of a joint (GPT8).
Articulation
The static and dynamic contact relationship between the occlusal surfaces of the teeth during function (GPT8).
Articulator
A mechanical device which represents the temporomandibular joints and the jaw members to which maxillary and mandibular casts may be attached to simulate jaw movements (
Atmospheric pressure
This can help resist dislodging forces if the dentures have an effective border seal. Peripheral seal or border seal is defined as the contact of
Balanced occlusion
The bilateral, simultaneous, anterior and posterior occlusal contact of teeth in centric and eccentric positions (GPT8)
Bench curing
a stage of resin processing that allows a chemical reaction to occur under the conditions present in the ambient environment (GPT8).
Bennett angle
The angle formed between the sagittal plane and the average path of the advancing condyle as viewed in the horizontal plane during lateral mandibular movements (
Border moulding
Determining the extension of a prosthesis by using tissue function or manual manipulation of the tissues to shape the border areas of an impression material (
Border movements
Mandibular movement at the limits dictated by anatomic structures, as viewed in a given plane (GPT8).
Camper’s line (ala-tragus line)
The line running from the inferior border of the ala of the nose to some defined point on the tragus of the ear, usually considered
