Direct Restorative Dentistry Final

Typed of indirect tooth colored materials

porcelain/ceramic - veneers

composite - inlay/anterior

lithium disilicate - strong

zirconia - strong

Ceramic indirect resto

Use anteriorly for aesthetics to repair fractured or worn dentition - adhere to enamel

• don’t use in patients with high caries risk

• Porcelain brittle so no heavy occlusion pt

Metal indirect resto indication

high occlusion

Ceramic inlay prep measurements

occlusal reduction: 1.5-2mm

isthmus: 2mm

taper: divergence

internal line angles: rounded and smooth

cavosurface margin: Butt joint of light bevel

obtuse exit angle

Etchable ceramics

Lithium Disilcate

• hydrofluoric acid etch

• silane coupling agend

• resin adhesive cement

non-etchable ceramics

Zirconia

• sand blasting

• MDP primers

• Self adhesive or resin cement

feldspathic porcelain

do not use for inlays or onlays becasue its brittle

FujiCEM 2

glass ionomer cement for Metal and zirconia

*not for ceramic because it is glass ionomer

Resin based luting agents

to cement ceramics

Custom Trays

used to make accurate final impressions

• rigid (no flexion)

• 2-3 mm thick

Uses for custom trays

• crown/bridge

• prostadontics

• removable partial denture

• implants

*precise margins that are uniform with minimal distortion

Extra control with custom trays

• more predictable (less overextension)

• more controlled pressure

• allows for uniform thickness

• less bulky

-reduces stress during removal and thermal contraction
