What is the condylar inclination?
What is the condylar inclination?
The condylar inclination represents the angle, steep vs. shallow, of the condyle translating down the condylar eminence as the mandible moves left, right and protrusive. The steeper the angle, the more quickly the back teeth come apart. The more shallow the angle, the slower the back teeth will disclude.
What is the condylar guidance angle?
As the condyle moves out of the most superior and anterior position from glenoid fossa, it slides along the posterior slope of the articular eminence. The angle at which the condyle moves away from the horizontal reference plane is referred to as the condylar guidance angle.
What is sagittal condylar angle?
Abstract. troduction: Sagittal condylar inclination (SCI) is the angle formed by protrusive condylar path and usually the Frankfort horizontal (or any other horizontal) reference plane [1]. It is an important parameter during oral rehabilitation [2].
What is Bennett angle?
Bennett angle – the angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movement as viewed in the horizontal plane. Bennett movement – the bodily lateral movement or lateral shift of the mandible during a laterotrusive movement.
What is condylar guidance?
Condylar guidance is described as the mandibular guidance generated by the condyle and articular disc traversing the contour of anterior slope of glenoid fossae or, synonymously, as the mechanical form located in the upper posterior region of the articulator that controls the movement of the mobile member.
What is protrusive movement?
Medical Definition of protrusive 1 : thrusting forward protrusive movements of the jaw. 2 : prominent, protuberant a protrusive jaw.
What does condylar mean?
/ˈkɒn.dɪ.lər/ relating to or like a condyle (= a round part at the end of a bone that forms part of a joint): condylar cartilage. SMART Vocabulary: related words and phrases. Bone structures.
What is lateral condylar guidance?
Condylar guidance [CG] by definition is the mandibular guidance generated by the condyle and articular disc traversing the contour of the glenoid fossa. Lateral condylar path is defined as the path of movement of the condyle-disk assembly in the joint cavity when a lateral mandibular movement is made.
How is Bennett angle measured?
The Bennett angle is the anatomic morphology of the medial wall of the glenoid cavity, and, by obtaining central and lateral wax-ups (which correspond to the beginning and end of the condylar shift or movement) it is possible to transfer data from an average value articulator by measuring the angle in degrees (4).
What is Lingualized occlusion?
Lingualized occlusion is a set‐up technique developed to enhance denture stability in such patients. In a lingualized occlusion scheme, buccal cusp contacts are eliminated to alleviate lateral stresses or lateral dislodging forces.
How are protrusive Records used to determine condylar inclination?
Turn or move the horizontal condylar indicator so it now contacts the condyle. This mimics the condylar inclination of the patient. You can do three protrusive records and get the average and use that as the condylar inclination. 1981 Board Question
How is the condylar inclination of the articulator determined?
Determining Condylar Inclination. The articulator condyle which is actually stationary is now in a downward and forward position relative to its centric relation position. Turn or move the horizontal condylar indicator so it now contacts the condyle. This mimics the condylar inclination of the patient.
How does the condyle move in the mandible?
When the patient goes into protrusive the condyle moves downward and forward. You of course cannot see this movement, but in the molar region of the mandible there is this same downward and forward movement. (This separation of the teeth or the ridges in the posterior region is called the Christianson phenomenon.)
