I. Class and composite
material
 Small – moderate cavities good level of oral
hygiene, cooperative patients.
Preparation
Fissures are open, cavity is like a box with
(rounded). No undercuts are prepared.The
cavosurface margin is smooth.
Making filling
 After preparation acid etching is performed
(phosphoric acid) – 20 – 30 s in enamel, 10 s in dentin
 Washing as long as acid etching
 Access of water is removed
 Primer and bond – disperse with air
 Light curing
 Application of the material – layers
 Light curing
 Finishing – diampond bur (yellow), polishing –
rubber rotary instrument.

Preparace na inlay
 Inlay je rigidní výplň
 Zhotovuje se mimo kavitu a do kavity se
upevní cementem
 Preparace je kavita s rozbíhavými stěnami
 Preparujeme lehce asymetricky
INLAYS
Inlay
 A rigid filling that is made out of oral cavity
amd is luted into cavity using a cement
Material
 metal alloy (goolden alloy)
 Composite
 Ceramics
Indication
 Big destruction of hard dental tissues
- It is not possible to make direct filling of
amalgam or composite
Contraindication
High risk of dental caries
Smal and shallow cavities
