TherapyCaries

pulp vital restoration

pulp inflamed or non-vital

root canal treatment or extraction



• Biocompatibility

• Adequate mechanical properties:

- press, strain, flex coefficient, resistivity

- elasticity

- surface hardness

- abrasion resistance

• Shape/form and volume stability

- tooth-similar thermal expansion

Cariestherapy Requirements



• Resistance against humidity, indissolubility, bonding

• Thermal and electrical isolation

• Antiseptic effect, caries-prophylactic properties

• Radiopacity

• Tooth-similar optical properties

• Simple application, finishing, polishing

• Easy removal

• Low price

Cariestherapy Requirements



• Temporary restorative materials

• Liners and bases

• Definitive restorative materials- Direct restorative dental materials (plastic)
