Advantages and Disadvantages of the Various Time Points for Implant Placement After Tooth Extraction

Question 1

Type 1

Advantages

Answer 1

1. Extraction and implant placement are combined in the same surgical procedure
2. Reduced overall treatment time compared to types 2, 3, and 4
3. Peri-implant defects often present as two- or three-walled defects, which are favorable for simultaneous bone augmentation procedures

Type 1=immediate implant placement

Question 2

type 1

Disadvantages

Answer 2

1. Morphology of the site may increase the difficulty of placing an implant in an ideal position
2. Morphology of the site may compromise initial implant stability
3. Lack of soft tissue volume makes attainment of tension-free primary closure more difficult
4. Increased risk of marginal mucosal recession
5. Inability to predict bone modeling may compromise outcomes

Type 1=immediate implant placement

Question 3

Type 2

Advantages

Answer 3

1. Reduced treatment time
2. Additional soft tissue volume allows for easier attainment of tension-free closure
3. Additional soft tissue volume may enhance soft tissue esthetic outcomes
4. Flattening of facial bone contours facilitates grafting of the facial surface of the bone
5. Peri-implant defects often present as two- or three-walled defects, which are favorable for simultaneous bone augmentation procedures
6. Allows for resolution of pathology associated with the extracted tooth

Type 2= 4–8 weeks
An implant is considered type 2 when the socket entrance is covered with mucosa.

Question 4

Type 2

Disadvantages

Answer 4

1. Two surgical procedures are required
2. Morphology of the site may compromise initial implant stability

Type 2= 4–8 weeks
An implant is considered type 2 when the socket entrance is covered with mucosa.

Question 5

Type 3

Advantages

Answer 5

1. Partial bone healing usually allows implant stability to be more readily attained
2. Additional soft tissue volume allows for easier attainment of tension-free closure
3. Additional soft tissue volume may enhance soft tissue-esthetic outcomes
4. Peri-implant defects often present as two- or three-walled defects, which are favorable for simultaneous bone augmentation procedures
5. Flattening of facial bone contours facilitates grafting of the facial surface of the bone
6. Allows for resolution of pathology associated with the extracted tooth

Type 3=10 to 16 weeks.
Type 3 is placed in a position that facilitates the prosthetic phase of the treatment.

Question 6

Type 3

Disadvantages

Answer 6

1. Two surgical procedures are required
2. Extended treatment time as compared to type 1 and type 2 placement
3. Socket walls exhibit varying amounts of resorption
4. Increased horizontal bone resorption may limit the volume of bone for implant placement

Type 3=10 to 16 weeks.
Type 3 is placed in a position that facilitates the prosthetic phase of the treatment.

Question 7

Type 4

Advantages

Answer 7

1. Bone healing usually allows implant stability to be readily attained
2. Additional soft tissue volume allows for easier attainment of tension-free closure
3. Additional soft tissue volume may enhance soft tissue esthetic outcomes
4. Allows for resolution of pathology associated with the extracted tooth

Type 4= 4 months (6-12 m usually)
When the implant is placed in a fully healed ridge. Such a ridge can be found after 4 months, but
more likely after 6–12 months of healing following tooth extraction (loss)

Question 8

Type 4

Disadvantages

Answer 8

1. Two surgical procedures are required
2. Extended treatment time compared to type 1, type 2, and type 3 placement
3. Socket walls exhibit greatest amounts of resorption
4. Greatest chance of increased bone resorption limiting the volume of bone for implant placement

Type 4= 4 months (6-12 m usually)
When the implant is placed in a fully healed ridge. Such a ridge can be found after 4 months, but
more likely after 6–12 months of healing following tooth extraction (loss)
