23.Biological complications in implantology, peri-implant mucositis and peri-implantitis

Question 1

Peri-implant disease

Answer 1

Inflammatory process in tissues surrounding implant

Question 2

Peri-implant mucositis

Answer 2

*Reversible inflammatory process=>
* Soft tissue surrounding functioning implant

Question 3

Peri-implantitis

Answer 3

Inflammatory process characterised by loss of peri-implant bone

Thickness of mucosa that covers alveolar process

Answer 4

2-4mm

Question 5

Peri-implant mucositis clinical features

Answer 5

• Similar to gingivitis
• Difference in morphology of mucosa=>

Question 9

Peri-implantitis clinical features

Answer 9

• Inflammation
• Loss of peri-implant bone

• Suppuration frequent

Question 10

Treatment of peri-implantitis

Answer 10
