14 Implant

Question 1

The most sensitive sensory input is from the ___ in the PDL.

The oral cavity’s sensory perception is known as the __ complex.

Answer 1

Periodontal mechanoreceptors (PMRs)

Stomatognathic complex

Question 2

Implant-assisted RPD benefit (8)

Answer 2

Improved: Retention, stability, support, comfort, hard/soft tissue replacement, esthetics, oral hygiene, patient satisfaction

Decreased: Need for clamping, surgical procedures, cost, alveolar bone resorption, stress on remaining natural dentition, risk of combination syndrome, need for corrected cast impressions, need for relines

Question 3

Implant Assisted RPD considerations

Answer 3

1. Patient education
2. Physiologic tolerances of oral tissues
3. Physiologic tolerances of patients adaptability
4. Variable prosthesis impact
5. Patient neuromuscular ability

Question 4

Circumstances where Implants are combined with RPD’s

• Supplement retention, stability, and support in Kennedy Class # and # rpd’s
• When implants with questionable anchorage or config would create favorable/unfavorable biomechanics for fixed
• Compensate for unanticipated loss of __ in key locations
• Used to substitute key ___ for RPD’s

Answer 4

1. Kennedy C 1 and 2
2. Unfavorable biomechanics
3. Loss of implants
4. Substitute key natural tooth abutments

Question 5

What is the difference in mobility between tooth and soft tissue?

Answer 5

25 times difference

Question 6

Indications for implant-assisted RPD (5 from the table)

Answer 6

1. Esthetics
2. Oral hygiene
3. Extensive ridge defects
4. Financial limitations
5. Extension base applications

Question 7

Does it matter if the implant abutment is parallel or not parallel to the path of insertion?

Answer 7

Yes, it does. If off-angle, it will place wear on the implant abutment components
