Bonded restorations

Bonded restorations use a process of adhesion creating a contact
of one material to another.

Non-Bonded restoration

Restorations are retained by mechanical retention between
restorative materials and tooth structure.

Direct restoration

applied to the tooth while the material is pliable/flexible. Some examples are amalgams, composites, glass ionomer, etc

indirect restoration

created in the lab, also known as castings. Can be gold or ceramic, final cast is either bonded or cemented into place.
