1.  The feedback management system in Oticon Medical Ponto sound processors is unique in that :
  1. It addresses feedback due to both static and dynamic feedback
  2. It allows easy measurement of individual static feedback limits through the Feedback Manager
  3. It allows the volume control to be used to its maximum range without feedback
  4. All of the above
2.  The wide implant diameter implant is designed to provide:
  1. Quicker healing period
  2. Improved initial stability
  3. Longer healing period
  4. None of the above
3.  Patient indications for a bone anchored hearing system are:
  1. 5 years of age and older
  2. Patients with mixed/conductive hearing loss
  3. Patients with single sided deafness
  4. All of the above
4.  The wide diameter implant plus ______ provide the largest initial bone contact surface
  1. Osstell ISQ
  2. Optigrip geometry
  3. 12 mm abutment
  4. None of the above
5.  Speech Guard in Oticon Medical Ponto is designed to
  1. Minimize signal distortion
  2. Increase battery life

8.  What percentage of larger initial implant surface contact with bone does the Optigrip geometry provide
  1. 5%
  2. 10%
  3. 15%
  4. 20%
9.  The Ponto abutment comes in the following sizes:
  1. 3, 4, 12 mm
  2. 3, 4, 6, 9 mm
