   3. Squamosodentary joint
   4. Primary joint
   
   
   
2. The first component of temporomandibular joint to become recognizable embryonically
   1. Condyle
   2. Articular disk
   3. Temporomandibular ligament
   4. Articular capsule
   
   
   
3. Following are the derivatives of Meckels cartilage, except
   1. Incus
   2. Temporomandibular ligament
   3. Anterior ligament of malleus
   4. Sphenomandibular ligament
   
   
   
4. The primary cause of Bennett movement is
   1. Inclination of articular eminence
   2. Tightness and orientation of temporomandibular ligament
   3. Tooth contacts and cuspal inclines
   4. Contraction of external pterygoid muscle
   
   
   
5. The unit of speech by which one utterance can be distinguished from another
   1. Phoneme
   2. Consonants
   3. Surd
   4. Sonant
   
   
   
6. “The only correct position of a tooth is the one in which it was placed by Nature” was stated by
   1. Misch
   2. Branemark
   3. De Van
   4. Boucher
   
   
   
7. The radiation dose around existing implants in mandible is increased by 11 to 15% in the adjacent 1mm zone due to
   1. Back scatter
   2. Transmission
   3. Absorption
   4. Coherent scattering
   
   
   
8. The combination of Monson and anti-Monson curves in posterior occlusion is referred to as
   1. Transverse compensating curve
   2. Reverse curve of Wilson
   3. Pleasure curve
   4. Curve of Von Spee
   
   
   
9. Choose the wrong statement
   1. Teeth with 30° cups set on a 0° plane of occlusion will balance in protrusive excursion if molar and incisal guidance are both 30°.
   2. Teeth with 30° cusps can be set in a compensating curve if the condylar guidance is 20° and the incisal guidance is 0°.
   3. If the incisal guidance is approximately 0°, it is impossible to use a tooth with a cuspal inclination higher than that of condylar guidance to achieve balance.
   4. If the incisal guidance is established considerably higher than the condylar guidance, it is virtually impossible to set teeth upright to achieve balance.

    2. Mandibular rotation
    3. Angular path of closure
    4. Mandibular deflection
