A
  1. Peri-implant mucositis
  2. Peri-implantitis
17
Q

Define peri-implant mucositis

A

18
Q

Define peri-implantitis

A
  • Irreversible
  • Gingival inflammation
  • Marginal bone loss
19
Q

How to prevent peri-implantitis?

A

> 1mm buccal plate thickness

20
Q

Risk factors for peri-implant disease (5)

A
  • Hx of periodontal disease
  • Poorly controlled diabetes
  • Smoker
  • Occlusal forces
  • Poor OH
21
Q

Post op advice post implant placement

A
  • Use CHX mw
  • Soft brush
  • ID tools: superfloss
  • Smoking cessation if required
22
Q

Why does suppuration occur in peri-implant disease?
