Question 1

What are the major ways we replace a single tooth?

Answer 1

• removable dental proesthesis RDP
• Fixed Denal preosthesis FDP
• No treatment
• Resin bonded prosthesis
• Implant

Question 2

What are the disdvantages of Implants?

Answer 2

Patient compliance

Time of tx

Consequence of failure

Cost to patient

Special training and equipment

Question 3

What are the endosseous root form implant complications?

Answer 3

-Surgical complications such as swallowing an instrument
-Implant loss
-Bone loss
-Soft tissue complications
Esthetics and phonetic complications

Question 4

What are the 14 reasons why its not worth replacing second molars with an implant?

Answer 4

1Not in esthetic zone

2 Extruded maxillary second molar not esthetic or occlusal consequence

3 1>5% of total chewing efficiency

4 10% higher bite force
Greater risk of bone loss, porcelain fracture, and abutment screw loosening

5 More often exhibits occlusal interferences during excursions

6 Higher and less predictable location of mandibular canal in that site

7 Submandibular fossa depth greater
Angulation of bone to occlusal plane greater

8 Limited to unfavorable crown height space for cement retention (increased risk of uncementation)

9 Limited access for occlusal screw placement

10 Limited access for correct implant body placement

11 Crossbite position – implant placed more buccal than maxillary tooth

12 Hygiene access more difficult

13 Cheek biting more common

14 a greater cost to the patient

Question 5

What are the abutment classifications?

Answer 5

Internal vs external connections
-Custom vs stock

Question 6

What are the indications of screw retained abutment.

Answer 6

Retrievability

• limited inter arch space
• Implant bridge
• Interim abutment
• Soft tissue management

Question 7

What are the indications of cement-retained restoration?

Answer 7

• Esthetic
• Ideal Occlusion
• Easier favrication and reduced cost
• Passive framework
• Maximize retention
