  • 51. MasseterMasseter •At the time of preliminary impression is made, while the compound on the borders of the impression tray in this region is still soft, considerable downward force should be exerted on the lower jaw by dentist. •Now the patient is attempting to counteract this downward pressure which will cause the masseter muscle to contract. •This forces the softened compound away from impingement in this region. www.indiandentalacademy.comn
  • 52. •Thus the denture border can also be contoured to accommodate this action. If this is not done the muscle interaction will displace the mandibular denture and force it in an anterior direction www.indiandentalacademy.comn
  • 53. Temporalis muscleTemporalis muscle  The action of this muscle is sometimes used as a test to determine whether the patient is closing in centric relation. www.indiandentalacademy.comn
  • 54. The Facial NerveThe Facial Nerve (N. Facialis; Seventh Nerve)(N. Facialis; Seventh Nerve) www.indiandentalacademy.comn
  • 55. Type:Type: The facial nerve mixed motor and sensory root www.indiandentalacademy.comn

  • 57. coursecourse •Entering the brain at the lower border of the pons. •sensory root pass into the substance of the medulla oblongata and end in the upper part of the terminal nucleus. •From the superficial attachments to the brain, the two roots of the facial nerve pass lateralward and forward to the internal acoustic meatus. www.indiandentalacademy.comn
  • 58. •In the meatus the motor root lies in a groove on the upper and anterior surface of the acoustic nerve, the sensory root being placed between them. •At the bottom of the meatus, the facial nerve enters the facial canal, termination at the stylomastoid foramen •On emerging from the stylomastoid foramen, the facial nerve runs forward in the substance of the parotid gland, and divides behind the ramus of the mandible into branches www.indiandentalacademy.comn
