Bio mechanical principles of prep for a PFM crown using shillingburg principles?
-1.5mm occlusal reduction , 1-1.5mm buccal shoulder and 0.5mm lingual chamfer
-retention and resistance using 5 degree taper
-structural durability using FCB , planar occlusal reduction and buccal/lingual axial reduction
-marginal integrity using bevel, shoulder and chamber , no undercuts
-preservation of periodontium finishing line supragingival so easy for dentist and pt to keep clean
What are standards of the dental team?
GDC guidelines
What standards of dental team can be breached by taking notes home?
-pt interest first as not acting wit integrity and being dishonest
-communicating effectively with pt sp no telling pt you are taking their notes home

-go to them first and speak to them calmly
-speak to ES and practice manager
-ask indemity

-report to data protection officer
-do a team meaning to make sure this does not happen again
-pt should be informed
-reflect on this situation
Consent process for sedation?
Should occur at appt prior to procedure
-pt aware of benefits and risks , how its carries out including cannula insertion

-transport
Childcare if children
-tell pt to bring meds to pt
-if Pt needs extra test like LFT, ECG, sickle cell test
-make sure they dont take sleeping tables, drugs
-do MDAS and ASA
What aspects of history and clinical assessment helps determine if suitable for implants?
-MH: not on bisphosphonates risk of MRONJ, poorly controlled diabetic , immunosuppressed infection, steroids so poor healing, bone disease MRONJ and poor bone less dense , RT, bleeding disorders
- allergy to TI
-SH smokes 20–300% increase of failure
-exam: needs enough space horizontally and vertically minimum space of 1.5mm between implant and teeth,
-perio stats
-caries risk
-access 2 minimum fingers
-skeletal pattern
-smile line
-pt expectations
If roots of nearby teeth are convergent what other options?
-try shorter implants but warn risk
-bridge fixed fixed or cantilevered
-RPD
-refer back to ortho to close gap ,
Composite build ups
