Question Answer
what is the difference between macromechanical and micromechanicalmacro is non-pin retention (intracoroal) and pin... then micromechanical is adhesives
what is a complex amalgamat least one cusp replaced
what should you do before you place the rubberdamcheck whole picture, examine occlusion, record MI contact, so if you need to reshape the supraerupted antagonist and visualize cusp height then rubber dam
when should you observe the occlusal morphology aka visualize the cusp height and positionbefore you rubber dam.
what do you have to consider when doing a complex amalgam restorations before you startit has to be cost effective, as definitive restoration and foundation for future indirect restorations
why is protective restoration a good thingbc it is less expensive to the 1000 crown and it still will provides for mastication
read in book page 50read in book page 50
what is another name for incomplete vertical fracturecracked tooth syndrome
what are positves about definitive restorationwhen the pulp and periodontal health are stable, it conserves tooth, it is only 230 dollars and it is a lot faster appointment
what extra retection support is needed for complex amalgam restorationpins, grooves, slots and coves, boxes, shelves and pulp chamber
before big restorations, can you leave caries in the toothno you have to remove everything bc you cant use auxiliary retention in weak/decayed dentin. FOR APPOINTMENTS, YOU HAVE TO REMOVE ALL CARIES BEFORE MAKING A ENDO OR PERIO REFERRAL
Why is it important to leave cuspa with adequate structureto place a matrix band against or guide carving
what is the general rule for cusp cappinglateral extension from primary groove to cusp tip. less than 1/2 then NO. if 1/2 to 2/3 then consider the environment the tooth is in then cap. if greater than 2/3 then you need to cusp cap
what is the minimum depth for the amalgam cusp in function and nonfunctionalin functional cusp it is 2mm minimum and for nonfunctional it is 1.5 mm
when prepping a cusp reduction, how should you make the floorflat where minimal thickness measured at thinnest area
what is a good way to prep a cusp using a bur of known size, that way you know how far to go down
what is the length of the 330 1.8
what is retention formany preparation design feature which prevents dislodgement of the restoration by tensile forces
