Bonding materials using interlocking surfaces, creating a physical connection.

Bonding materials using chemical reactions to create a true chemical bond.

Removing or modifying the smear layer on tooth structure using acid.

A thin layer of debris on the tooth surface created during preparation.

Tooth bonding strategy using acid etching, primer, and bonding agent.

Directly bonds to partially demineralized surface using a primer that contains functional monomers.

Versatile adhesive system for use with either etch and rinse or self-etch protocols

Difficulty in obtaining lasting bonding to dentin due to its complex structure and issues with retention.

Dental alloy with >40% gold and >60% noble metal content.

Dental alloy with >25% noble metal content, does not need gold.

Dental alloy with <25% noble metal content, doesn't need gold.

Range of temperatures over which an alloy melts and solidifies.

The temperature at which all of an alloy melts.

Temperature at which all of an alloy freezes.

Measure of mass per unit volume of an alloy.

Properties determining alloy's ability to resist deformation/failure.

Restorations made entirely of ceramic materials, replacing metal cores.

Glassy or glassy-dominated ceramics used for aesthetic purposes; translucent.

Materials used to create records (impressions) of the teeth and mouth.

Impression materials that are dissolving solids (solute) in a liquid (solvent).

Flexible, cross-linked polymers for more accurate impressions.

A type of elastomeric impression material, supplied as 2-part system, hydrophilic.

Elastomeric impression materials with good hydrophilic properties, but limited dimensional stability.

Cross-linking of alginate chains by replacing Na+ ions with Ca++ ions.

Casting waxes are used to create the wax pattern for the metallic framework of removable partial dentures.

Base plate waxes shape the denture's contours and hold teeth in place before final processing.

Base plate waxes are classified by hardness: Type I (soft) for contouring, Type II (medium) for temperate climates, and Type III (hard) for tropical climates.

Boxing waxes are used to create a box-like structure around impressions, ensuring accurate pouring of the cast.

Utility waxes are highly adaptable, used to adjust trays, provide rim support, and prevent irritation during impression taking.

The amount of water added to 100 grams of gypsum powder.

Increasing the W/P ratio leads to a longer setting time for gypsum products.

Increasing the W/P ratio weakens the gypsum product.

Gypsum materials expand during setting, impacting dimensional accuracy.

Plaster expands the most, followed by dental stone, then high-strength stone.

Expansion of gypsum caused by absorbing ambient humidity or water on the surface.

Liquids that can increase gypsum hardness and abrasion resistance.

Gypsum products work well with various dental materials like alginate, silicones, and polyethers.

The time you have to mix and work with an impression material before it starts to set.

The time it takes for an impression material to completely solidify, becoming rigid.

Higher temperatures shorten setting time, making the material set faster. Lower temperatures extend setting time, making the material set slower.

More water (thinner mix) increases working and setting time, making the material set slower. Less water (thicker mix) decreases working and setting time, making the material set faster.

Under-mixing or over-mixing weakens the material, impacting its overall strength and quality.

The ability of an impression material to return to its original shape after being deformed.

Faster loading results in higher mechanical properties and greater strength in alginate.

Alginate has low tear strength, limited elasticity, limited surface detail, and dimensional stability issues when stored.
