- what is the purpose of a matrix system
-
restore proximal wall
smooth surface restorative material - define proximal wall
- mesial distal surfaces to adjacent tooth
- define contact area
- mesial or distal surface of tooth touches adjacent tooth in same arch
- what type of matrix system is used for posterior restorations
- tofflemire retainer matrix band and wooden wedge
- what is the matrix system used for anterior restorations

- t-band
- what is the purpose of the matrix band
-
recieves and holds matrix band
secures matrix band around tooth - What does the matrix band provide for the surface with restorative material
- contour
- what does the matrix band provide for the restorative material
- surface area where it can be condensed
- what does the matrix band do for the adjacent tooth
- contact area
- what does the matrix band do for for the tooth being restored
- no overflow atonomy proper height and function
- what is the purpose of the wedge
-
no overhang
seperate teeth make interproximal contact
hold matrix in position - what is the spot welded band usualy used for
- primary molars
- how do you make a spot welded costum band
- fit tooth, place in welder, metal fuse
- what is the difference between automatrix and tofflemire
- no retainer hold in place but has wrench instead
- what is the sectional matrices used for
- posterior composite
- what is the sectional matrices
- thin palodent type matrix band used with tension ring
- what is used for anterior restorations
- clear plastic matrix
- define wizard wedge
- trianglur wooden wedge
- define prmier wedge
- wooden or plastic can be triangular or rounded
- where does the retainer open guidepost point to
- gingiva
- which side the tofflemire have to be pointed from and parrel to
- vestibular side
- where does the handle of the tofflemire extend from
- mouth not lip
- how is the matrix band held in the retainer
- firmly stable and securley
- when is the matrix band snug
- bigger than tooth
- what does the shape of the band approx
- shape of missing tooth wall
- is there a gap between gingival floor and band
- no
- is there any impigement or dam trapped
- no
- what sort of wedge is the best
- bigger then embrarsure
- what side do you place the wedge from
- lingual opposite side of retainer
- what happens if you are restoring both sides mesial and distal
- 2 wedges placed
- what does the flatter side of the wedge face
- gingiva
- what does the pointed part of the embrasure face
- occlusal
- how far do we typicaly put in a wedge
- half way
- where should the base of the wedge be positioned
- slightly gingival or apical to floor cavity prep
- how do we remove wedge
- grasp base remove from lingual straight pulling motion
- how do we loosen retainer
- placing finger on occlusal turn slowly until spindle comeo ut from vise
- what is step three how do we slide retainer where
- carefully smoothly to occlusal surface
- what is step 4
- ease bandproximal wall surface does no restortion
- step five how do you lift band what way
- gently occlusal using seesaw from new restortion
- what is the t band made from
- cooper
- where is t band placed
- primary molars
- what is the anterior plastic strip refered to as
- mylar or celluloid
- where do you place the wedge in anteriors if restorative on labial
- lingual
- what about wedg on anteriors on the lingual or they place on labial
- yes
- where do you put ceeloid strip
- where proximal wall removed
- what do you wrap celluloid aroud
- facial and lingual
- how is the material placed when using celluloid
- ends open up
- what happens when you finish putting the restorative material in on anteriors using culloid strip
- wrapped again facial lingual
- why does the order of taking off the items not matter in anteriors
- tooth restorative material for anterior is as hard as it can be
