Temporomandibular joint belongs to which of the following joint:
Cartilaginous
Fibrous
Synovial
Sterno-costal
Which of the following structures divides the TMJ in two?
Right & left Condylar heads
Articular disk
Capsule and supportive ligaments
Articular eminence
The right and left heads of the mandibular condyles articulate in which of the following structures?
Condyloid process
Coronoid process.
Articular eminence
Glenoid fossae
An unusual feature of temporomandibular joint as compared to all other joints in the human body is :
Intra-articular disk divides joint cavity into two joint spaces
Synovial joint with synovial fluid & synovial membrane
Primary & secondary cartilages are present
It is affected by osteoarthritis frequently
It has muscles and ligaments supporting it
Which one of the following is not a function ascribed to the intra-articular disc:
Acts as a shock absorber
Improves the fit between the bony surfaces
Provides instability during the movement
Spread synovial fluid
Superior and anterior position of the mandible with the disc properly interposed is known as:
Centric relation
Centric occlusion
Ideal occlusion
Long centric
Which of the following describes the most stable position of the condyle?
Centric occlusion
Centric relation
Long centric
Ideal occlusion
Maximum intercuspation of teeth contacting in a position that the patient finds the most comfortable is known as :
Early lateral movements of the mandible should ideally be :
Guided by anterior teeth
Guided by canines
Guided by all the posterior teeth known as group function
Dental occlusion refers to:
Relationship of teeth within the dental arches
Relationship of the condyle in rest position of mandible
Relationship of the dental arches when tooth contact is made
curvature of the dental arches in the anterio-posterior direction
Characteristics of plane of occlusion include :
Teeth are positioned in the arches at 90 degrees with respect to the occlusal plane
Bucco-lingual curvature is seen only in mandibular posterior teeth
This is a flat plane to enable maximum contacts of teeth
Curved plane that permits maximum use of tooth contacts during function
What is the term for the position of the mandible when the cusps of the teeth interdigitate maximally?
Functional occlusion
Centric relation
Maximum intercuspation
Centric occlusion
The oblique ridge found on a maxillary first molar is formed by
the union of which of the following structures?
Triangular ridge of the mesiobuccal cusp and the
triangular ridge of the distolingual cusp
Triangular ridge of the mesiolingual cusp and the
triangular ridge of the distobuccal cusp
Distal cusp ridge of the mesiobuccal cusp and the triangular ridge of the distolingual cusp
Distal cusp ridge of the mesiolingual cusp and the
triangular ridge of the distobuccal cusp
