Dental Bridges and Restorations Quiz

Pre-made temporary crowns that can be trimmed and cemented onto prepared teeth.

Various materials like polycarbonate, metal (aluminum, nickel-chromium, stainless steel), and acrylic are used for temporary crowns.

Prefabricated crowns are trimmed and cemented in place using an adhesive material which is easy to remove later.

A technique for treating carious deciduous molars using preformed metal crowns (PMCs) without removing the decay or preparing the tooth.

A laboratory-made device that replaces missing teeth by joining multiple crowns together.

A bridge that is made of several units that are the same as single crowns joined together.

Pre-made temporary crowns for the back teeth made of metal.

Metal crowns used in the treatment of caries in deciduous molars and some non-carious cases.

A bridge with a joint allowing flexibility; a type of dental bridge.

A dental bridge where retainers are on one side of the pontic.

A cantilever bridge with retainers right next to the pontic.

A cantilever bridge with retainers further from the pontic.

A bridge that needs minimal tooth work for fixing, relying on dental wings.

A rigid bridge; less commonly used now.

Dental bridge fixing posterior teeth (back teeth).

Natural teeth supporting a dental bridge.

Patients without opposing teeth or with dentures as opposing teeth, reducing occlusal forces.

More extensive palatal/lingual preparation, possibly extending to cusps, compared to conventional bridges.

Prevents tooth sensitivity, space closure, and overeruption of supporting teeth during bridge preparation and fitting.

Made in a similar manner to a chairside constructed temporary crown.

Composite resin (like Temphase or ProTemp) is used to create the temporary bridge within the impression.

Temporary cement is used to retain the temporary bridge until the permanent bridge is cemented.

Dual-curing resin cements with primers provide a strong chemical bond between the abutment teeth and the metal wings of the bridge.

Flanges are made retentive by acid etching and sandblasting before applying an adhesive resin like Panavia Ex.

Dental floss with a stiff end for cleaning under bridge pontics.

A small brush used to clean under bridge pontics.

A toothbrush that uses vibrations to clean teeth.

Porcelain or composite coverings for the front of teeth.

Removing dental tissue to prepare for a crown.

Injury to the soft tissue inside a tooth.

Thin porcelain coverings for the front of teeth (made in a lab).

Thin composite coverings for the front of teeth (applied by dentist).

A silane agent applied to the veneer surface to create a chemical bond with the luting cement for strong adhesion.

The tooth is isolated using materials like rubber dam, celluloid strips, or PTFE tape to prevent contamination during veneer placement.

A resin adhesive that bonds both to the tooth and the veneer, often light-activated for curing.

A laboratory-made restoration that fits into a prepared cavity in a tooth, replacing a filling.

Inlays are typically made of gold alloy, porcelain, or a special, stronger type of composite.

Inlays provide higher strength, permanence, and better aesthetics compared to fillings.

Inlays are typically used for teeth with lost cusps, heavy occlusal forces, or when fillings are not strong enough.

Modern composite materials, especially bulk-fill types, have reduced the use of inlays as filling materials become more effective.

There are two main types of dentures: full dentures for people with no teeth and partial dentures for those with some missing teeth.

Acrylic is the most common material for dentures, made by mixing a powder (polymer) with a liquid (monomer).

Acrylic dentures harden through a process called curing. It's done by heating the mixture (heat curing) or adding a catalyst (cold curing).

Dentures stay in place thanks to factors like a suction film of saliva, a post-dam, accurate fit, and undercuts in the mouth.

A post-dam is a ridge along the back of the upper denture that helps create suction and improve denture stability.

Partial dentures use clasps, which are metal loops around remaining teeth, to increase retention and prevent dislodgement.

This type of acrylic denture is cured by technicians in a lab using heat.

This acrylic cures at room temperature by adding a special chemical (catalyst). Used for temporary crowns and repairs.
