Q

inflamm response in teeth vs implants and reversal?

A

Stronger inflammatory response was
around implants than teeth; need
longer time to complete reverse
peri-mucositis than gingivitis

20
Q

Peri-implantitis vs periodontitis histo

A

Peri-implantitis contained larger
proportions of neutrophil granulocytes
and osteoclasts than in periodontitis

21
Q

Peri-implantitis risk factors/indicators

A
  • Poor plaque control
  • Lack of regular maintenance
  • Tissue quality: thin phenotype, bonedeficiency
  • Iatrogenic factors: malpositioning, poor design of emergency profile, inadequate abutment/implant seating
  • Excessive cement
  • Occlusal overload
  • Titanium particles: implant corrosion, micromovement
    History of periodontal disease
    Smoking
    DM
    Genetic factors/
    systemic condition
22
Q

peri implantits presentation

A
  • Inflammation: redness, swelling
  • Pain
  • Suppuration
  • Bone loss
23
Q

how does peri implantitis occur

A

susceptiable host with microbial dysbiosis

24
Q

clinical exam of implants

A

Peri-implant tissue
Occlusion and mobility
Plaque, probing depth, BOP, exudates

25
Q

Peri-implant probing Diagnostic Procedures

Q

MAINTENANCE OF DENTAL IMPLANTS
* Provide guidelines for?
* Focus on?
* Work as a team?
* Prevent future complications by?

A
  • Provide guidelines for maintaining the long term health of the dental implant
  • Focus on both hard and soft tissue stability around the dental implant
  • Work as a team— patient are co-therapists in the maintenance therapy
  • Prevent future complications by thorough diagnosis and treatment planning
38
Q

WHY of implant maintenance
* Detect?
* Plan corrective interventions
* Important clinical decisions must be reached at?

A
  • Detect early signs of disease
  • Plan corrective interventions
  • Important clinical decisions must be reached at several stages during treatment and maintenance of implant patients
39
Q

HOW of implant maintenance
Establish useful set of clinical parameters to?
components of this?

A

Establish useful set of clinical parameters to evaluate dental implants
Components:
1. Assessment of home care
1. Examination of peri-implant soft tissue
1. Radiographic examination

40
Q

A

Examples of varying protocols are:
Initial placement: 3 months, 6 months, 12 months, every 2 years.

Initial placement: every 6 months if pathology present.

41
Q

WHAT of implant maintenance

  • A thorough review of?
  • Deposit removal?

Interproximal brushes can effectively
penetrate up to 3mm into a gingival
sulcus and may effectively clean a

SCALERS MADE OF STAINLESS STEEL AND ULTRASONIC TIPS CAN ROUGHEN THE IMPLANT SURFACES CREATING SCARRING AND PITTING
use Ti or plastic instead
