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
Peri-implant probing Diagnostic Procedures Variables in peri-implant probing
Variables: - Probe Positioning - Presence of Inflammation (BoP, Exudates) Plastic or Metal? DOESNT MATTER
26
Occlusal Evaluation and Mobility of implants
27
Successful and stable osseointegrated implants mobility?
Successful and stable osseointegrated implants exhibited NO mobility
28
what could be loosened from occ/mobility?
29
Peri-implant tissue examination
The impact of the soft tissue phenotype modification on peri-implant health
30
KERATINIZED TISSUE WIDTH MUCOSA THICKNESS INITIAL TISSUE THICKNESS | req for success of implant

31
Radiogrpahic exam Peri-implant radiolucency Bone level Assessment | to be considered successful?
< 0.2mm bone loss per year after the 1st-year loading < 2mm bone loss starting after loading

37
MAINTENANCE OF DENTAL IMPLANTS * Provide guidelines for? * Focus on? * Work as a team? * Prevent future complications by?
* 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
WHY of implant maintenance * Detect? * Plan corrective interventions * Important clinical decisions must be reached at?
* 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
HOW of implant maintenance Establish useful set of clinical parameters to? components of this?
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
RADIOGRAPH protocols for follow up
Examples of varying protocols are: Initial placement: 3 months, 6 months, 12 months, every 2 years. Initial placement: 6 months, 12 months, and every 2 years if no pathology present. Initial placement: every 6 months if pathology present.
41
# WHAT of implant maintenance * A thorough review of? * Deposit removal? * Appropriate use of? * Reevaluation of?
* A thorough review of oral hygiene reinforcement and modifications * Deposit removal from implant/prosthesis surfaces * Appropriate use of antibiotics * Reevaluation of the present maintenance interval, with modification as dictated by the clinical presentation
42
# oral hy mod: IP brushes
Interproximal brushes can effectively penetrate up to 3mm into a gingival sulcus and may effectively clean a peri-implant sulcus
43
# what tools to avoid with devbridement
SCALERS MADE OF STAINLESS STEEL AND ULTRASONIC TIPS CAN ROUGHEN THE IMPLANT SURFACES CREATING SCARRING AND PITTING use Ti or plastic instead

45
# WHEN of implant maintenance * Maintenance treatment should be customized according to? * Patients with history of periodontitis with acceptable self-care: * Patients with no systemic or local risk factors:
* Maintenance treatment should be customized according to each patient’s systemic and local risk factors. * Patients with history of periodontitis with acceptable self-care: 3-month recare interval * Patients with no systemic or local risk factors: 6 month recare interval
46
SUMMARY * Respect the what when placing implants? * Evaluate implants at every? * Know the implant complications * Detect early, treat accordingly or refer/consult early?
* Respect the biology when placing implants * Evaluate implants at every maintenance appointment * Know the implant complications * Detect early, treat accordingly or refer/consult early
47
# critical areas for implant maintenance/ reevaluation
* peri-implat tissue * connection of prothesis and implant * prothesis * bone level
