What are the steps of amalgam restoration?

When placing dental amalgam, the dentist first drills the tooth to remove the decay and then shapes the tooth cavity for placement of the amalgam filling. Next, under appropriate safety conditions, the dentist mixes the encapsulated powdered alloy with the liquid mercury to form an amalgam putty.

How do you remove overhang from amalgam?

Some methods for removing proximal amalgam overhangs are the EVA reciprocating motor driven system, roto-pro, flame-shaped steel bur, diamond bur and sonic scaler.

What instructions should you give a patient after a new amalgam filling has been placed?

1- Do not eat on your new filling for one hour and until your numbness is gone. 2- If you are supervising children who had fillings done, make sure they don’t bite on their numb lips or tongue (it can cause serious injury to their soft tissue). 3- Do not bite hard or chew on silver amalgam fillings for 24 hours.

What is class1 restoration?

1. Class I: Cavity in pits or fissures on the occlusal surfaces of molars and premolars; facial and lingual surfaces of molars; lingual surfaces of maxillary incisors (Class I corresponds to surfaces of a posterior tooth you can clinically see—occlusal/lingual/buccal surfaces.

What is the setting time of amalgam?

The setting time of amalgam depends on the composition of the alloy, the shape and size of the particle and the mixing time. 90 % of the final hardness will be reached after 10 – 12 hours.

What are the steps for a composite filling?

The steps of placing dental bonding (composite restorations):

1. Preparing (trimming) the tooth (when needed).
2. Acid etching the enamel (and dentin)
3. Applying the bonding agent.
4. Placing the dental composite.
5. Curing the restoration.
6. Final shaping and polishing.
7. Aftercare. / Precautions.

What instruments are needed for an amalgam filling?

Restorative dental hand instruments include the amalgam carrier, burnisher, condensers, composite placement instruments, carvers, and Woodsen.

• Amalgam Carrier – used to carry an increment of amalgam directly into the prepared tooth.
• Burnisher – used to smooth the surface of a freshly placed amalgam restoration.

What are the principles of cavity preparation?

The main principles of cavity preparation are to preserve the underlying tooth structure, protect the pulp tissue, save as much as Enamel or Dentin as possible, shape the cavity to achieve maximum resistance and Retention as possible depending on the type of restoration used to help in bearing the mastication forces.

Can you brush and floss after a filling?

Don’t hesitate to brush your teeth or floss after a filling. As long as you brush gently and floss carefully around the tooth, you should be able to keep the area clean as usual.

Is bevelling done in amalgam restoration?

In composite and bonded amalgam restorations beveling which is done on non-stress bearing areas provide the following. Increase the surface area of etchable enamel, enamel rods, dentin and dentinal tubules, thereby maximize the effectiveness of the bond and provide stronger bond by etching more number of enamel rods.

How do you remove amalgam overhangs?

Some methods for removing proximal amalgam overhangs are the EVA reciprocating motor driven system, roto-pro, flame-shaped steel bur, diamond bur and sonic scaler. This article illustrates the trimmed surface after overhang removal with photographs taken at 1:1 magnification.

What are the methods of amalgam restoration?

• The procedure of adding an increment,condensing it,adding another increment and so forth is continued until the cavity is overfillled. • In case the cavity is large well condensed amalgam restoration can be achieved when the mix has proper consistency.

How do you burnish the Matrix Band of an amalgam?

This prevents the matrix band from being too tight, which may lead to an open contact and may hinder proper condensation of the amalgam into the proximal cavosurface margin areas Finally, use a spoon excavator or burnisher to burnish the matrix band to the adjacent proximal contact area.

What is a Class II amalgam restoration?

Back to Class II Amalgam Restoration | Back to Operative Videos. The Universal (Tofflemire) matrix system is used in Class II restorations. The primary function of the matrix is to restore anatomic proximal contours and contact areas. A properly placed matrix should: Be rigid against the existing tooth structure.
