What is the primary function of dental crowns?
To protect and strengthen damaged teeth
ExplanationDental crowns protect and strengthen teeth by covering them completely.
#2
Which dental prosthetic is removable and used to replace one or more missing teeth?

#3
What is the purpose of dental veneers?
To enhance the appearance of front teeth
ExplanationDental veneers are thin shells of porcelain or composite resin placed over the front surface of teeth to improve their appearance by altering color, shape, size, or length.
#4
What is the purpose of a gingival retraction cord in crown procedures?
To expose the margin of the preparation
ExplanationGingival retraction cords are used in crown procedures to displace and retract gingival tissue, exposing the margin of the tooth preparation for accurate impression taking.
#5
What is the purpose of a provisional (temporary) crown in crown procedures?
To provide a temporary solution while the final crown is being fabricated
ExplanationProvisional crowns, also known as temporary crowns, are placed to protect and maintain tooth structure while the final crown is being fabricated in a dental laboratory.
#6
Which material is commonly used for making dental crowns?
Porcelain
ExplanationPorcelain is a common material used for its natural appearance and durability in dental crowns.
#7
What is the purpose of a dental bridge?
To replace a missing tooth or teeth
ExplanationDental bridges are used to replace missing teeth by anchoring artificial teeth to adjacent natural teeth.
#8
What is the purpose of abutment teeth in dental prosthetics?
To serve as anchors for dental prosthetics
ExplanationAbutment teeth provide support and stability for dental prosthetics like bridges and dentures by serving as anchor points.
#9
What is the purpose of a post and core in dental restoration?
To strengthen a tooth before crown placement
ExplanationA post and core provide internal support and stability to a tooth before a crown is placed, ensuring its long-term success.
#10

ExplanationDental articulators are devices used in prosthodontics to replicate the movements and relationship between upper and lower jaws, aiding in the fabrication of dental prosthetics.
#16
Which factor is crucial for the success of an osseointegrated dental implant?
Bone integration
ExplanationOsseointegration, the direct connection between the dental implant and surrounding bone tissue, is crucial for the long-term success and stability of dental implants.
#17
Which type of dental crown requires the least amount of tooth reduction?
All-ceramic
ExplanationAll-ceramic crowns require minimal tooth reduction compared to other types, preserving more natural tooth structure while providing esthetic results.
