Question 4

Mechancial/ technical complications

The most common mechanical complication is

Answer 4

screw loosening followed by screw fracture for implant- supported prosthesis.

Question 5

Mechancial/ technical complications

Which arch is more prone to implant related mechanical complications and failure?

Answer 5

Maxillary arch was more prone to implant related mechanical complications and failures compared to the mandibular arch

Question 6

Mechancial/ technical complications

Implant fractures:

Answer 6

Rare but not exceptional - Fracture of a dental implant that has undergone osseointegration by which the prosthesis is adversely affected by the loss of the supporting tissue .

Question 7

Mechancial/ technical complications

Other causes of Implant fracture :

Answer 7

1. Implant design and manufacturing defects
2. Nonpassive fit of the prosthetic framework
3. Physiologic or biomechanical overload

Question 8

Mechancial/ technical complications

Answer 8

Question 9

Iatrogenic complications

Answer 9

1. Nasal floor perforation
2. Mandibular bone fracuture
3. Implant fracture
4. Excessive torque during insertion
5. Nerve or tissue damage - Implant inadvertently placed too close to a nerve causing numbness, tingling, or pain.
