Implant placement protocol

Question 1

List the four types of implant protocols

Answer 1

Type 1:
Immediate

Type 2:
Early

Type 3:
Delayed

Type 4:
Late

Question 2

For the type 1 “immediate” protocol, do the following:

• Define
• Provide advantages
• Provide disadvantages

Answer 2

Definition:
Implant placed right after extraction

Advantages:
• Less surgery required since it is both done at once
• Reduced treatment time

Disadvantages:
• Thin tissue biotype may compromise optimal outcome
• If lack of keratinised mucosa, difficult flap adaptation

Question 3

For the type 2 “early” protocol, do the following:

• Define (provide timeframe)
• Provide advantages
• Provide disadvantages

Answer 3

Definition:
Socket is completely covered by soft tissue (4- 8 wks)

Advantages:
• Increased soft tissue volume which enables flap management

Disadvantages:
• Site morphology may complicate placement and anchorage
• Socket walls exhibit varying amounts of absorption
• Treatment time increased

Question 4

For the type 3 “delayed” protocol, do the following:

• Define (provide timeframe)
• Provide advantages
• Provide disadvantages

Answer 4

Definition:
Substantial bone fill of the socket (12- 16 wks)

Advantages:
• Substantial bone fill of socket facilitates implant placement
• Mature soft tissue enables flap management

Disadvantages:
• Adjunctive surgery may be required
• Socket walls exhibit varying amounts of absorption
• Treatment time increased

Question 5

For the type 4 “late” protocol, do the following:

• Define (provide timeframe)
• Provide advantages
• Provide disadvantages

Answer 5

Definition:
Healed socket (more than 16 weeks) 

Advantages:
• Clinically healed ridge
• Mature soft tissue enables flap management

Disadvantages:
• Large variations present in available bone volume
• Treatment time increased
