Implant symposium Flashcards
What are the 2 stages of osseointegration?
- Primary osseointegration
- Secondary osseointgratoin
Osseointegration is a direct functional and structural connection between a dental implant and bone
What is primary osseointegration?
implant anchored by frictional forces between osteotomy and dental implant design features
What is secondary osteotomy?
process of functional connection between bone and dental implant
What 3 materials are used for dental implants?
- Titanium (type 4)
- Titanium Zirconium
- Ceramic implant
What 3 factors indicate the dimension of an implant?
- Site
- Indication
- Local anatomy
What are 3 aims of placing a dental implant?
- replace missing teeth with aesthetic functional and predictable restoration
- low rate of complications
- long term stability
What 4 medications could contra-indicate implant placement?
- SSRI
- PPI
- Bisphosphonates
- Steroids
What 2 medical conditions/therapies would contraindicate implant placement?
- Poorly controlled diabetes
- Radiotherapy
Which medical condition is associated with increased survival rate of implants?
Cardiovascular disease
When should implant be placed (age related)?
After cessation of growth
What are 3 risks of placing implants in a patient who is not skeletally mature?
- Infra-occlusion
- compromised aesthetics
- implant fenestration
What is the minimum inter-proximal distance between an implant and adjacent teeth?
1.5mm
Where would you use a bone level implant?
in aesthetic zones
Where would you use a tissue level implant?
Posteriorly
Where would you use a tapered implant over a parallel one?
- where there is root convergence apically
What 5 special investigations would an implantologist do to assess implant placement?
- Study models
- CBCT
- Clinical photographs
- Surgical guide
- Surgical template
Why is there high failure of implants in smokers? 2
- Because it can affect vascularity and osteoblasts/fibroblasts activity
- higher risk of peri-implantitis
Two types of implant retained prosthesis?
- Removable
- Fixed
What are the two impression techniques for implants?
- Open tray
- Closed tray
What are 2 benefits of open tray impression for implants?
- high accuracy
- accurate positioning due to tactile response
What are two benefits of closed tray impression?
- no additional preparation of tray
- high accuracy
How much space do you need between implants?
3mm
Give 4 reason why soft tissue might be compromised in an area for implant placement?
- Trauma
- Post extraction defects
- Hypodontia
- Periodontal disease
What 4 things determine the aesthetic outcome of an implant?
- 3d implant position
- Bone volume and morphology
- Space dimensions
- Gingival biotype
What are the two types of peri-implant disease?
- Peri-implant mucositis and peri-implantitis
What are 4 risk factors of peri-implant disease?
- Poor oral hygiene
- Smoking
- History of periodontal disease
- Poorly controlled diabetes
What is peri-implant mucositis?
Inflammation of the mucosa at an implant area with no loss of supporting bone
What is peri-implantitis?
Inflammation of the mucosa at an implant area with loss of supporting bone
What is the advised treatment for peri-implant mucositis?
- non surgical instrumentation and CHX
What are 3 signs of peri-implantitis grade 0?
- failure of osseointegration
- Implant fracture
- Implant mobility >1mm horizontal
What is the advised treatment for peri-implantitis grade 0
Explant
3 signs of grade 1 peri-implantitis?
- PPD < 4mm
- Bone loss < 2mm
- Foreign body in peri-implant sulcus
What is the treatment advised for mild peri-implantitis?
- Removal of abutment
- non surgical instrumentation and disinfection
3 signs peri-implantitis grade 2
- Bleeding on probing
- PPD 4-6mm
- Bone loss less than 2mm
What treatment is advised for moderate peri-implantitis?
- Removal of abutment
- non surgical instrumentation and disinfection
What are 3 signs of peri-implantitis grade 3?
- BoP
- PPD >6 mm
- Bone loss more than 2mm
What is the treatment advised for severe peri-implantitis?
- removal of abutment
- surgical access
- instrumentation and disinfection
- systemic antibiotics
- resective or regenerative surgery
A patient just got an implant , give 5 post op advice you would give the patient?
- Use Chlorhexidine mouthwash
- Soft toothbrushing until healing takes place
- Use of interdental brushes , 360 flossing technique
- Use of super-floss and single tufted brush
- Smoking cessation if applicable
When you probe around an implant , at how many points would you probe?
4
What sign indicated peri-implant stability?
Absence of bleeding on probing
How many times a year would you recall an implant patient?
3 times
What types of instruments would you for no surgical instrumentation in peri-implant disease patients?
- Carbon fibre
- Titanium
