FP1: MCR
At COD, coping of MCR is made of
Argebond 80
for MCR, metal coping is _____mm thick and opaque porcelain is _____mm thick
dentin and teeth porcelain= _______mm
general discount= 1.5mm
metallic coping= zero.3mm
opaque porcelain= zero.2mm
dentin+enamel= 1mm
3 functions of opaque porcelain in MCR
1. Blocks out shade of metal
2. Establishes bond to metal
3. Initiates selected colour
indicators for metallic ceramic restorations:
1. Esthetic requirement
2. Pt with occlusal compromises (ant overbite, occlusal put on)
three. Restricted interarch area
four. Darkish dentin or center construct-up
contraindications for MCR
metallic allergic reaction
esthetic needs
porcelain butt margin= ______ shoulder
metal collar margin= shoulder with _______
radial
bevel
axial reduction is finished for adequate strength of substances, that's supportive of what
concept?
Structural durability
