What is a 'stock abutment' in implant dentistry?
Answer: A pre-manufactured abutment made to standard dimensions by the implant manufacturer
A stock abutment is a prefabricated, standardized component supplied by the implant manufacturer in set sizes and angulations.
Which cement type is most commonly preferred for permanent cement-retained implant crowns due to its strength and retrievability?
Answer: Resin-modified glass ionomer or resin cement
Resin-modified glass ionomer or resin cement is preferred for cement-retained implant crowns because it provides sufficient strength while allowing retrieval if needed.
What is the purpose of the 'emergence profile' in implant prosthetics?
Answer: To shape the soft tissue contour as the restoration emerges from the gingiva
The emergence profile defines the contour of the restoration as it transitions from the implant platform through the soft tissue to the crown, influencing esthetics and peri-implant tissue health.
Which full-arch implant restoration concept typically uses 4–6 implants to support a complete non-removable arch of teeth?
Answer: Implant-supported fixed full-arch bridge
An implant-supported fixed full-arch bridge (such as All-on-4) uses 4–6 implants to support a complete arch of teeth in a fixed, non-removable framework.
What is the primary function of a healing abutment (healing cap) after implant placement?
Answer: To guide and shape the peri-implant soft tissue during the healing period
A healing abutment is placed after implant surgery to guide and shape the peri-implant gingival tissue into the desired contour before the final restoration is fabricated.
In implant prosthodontics, what does 'passive fit' of a prosthetic framework mean?
Answer: The framework seats completely on all abutments simultaneously without inducing internal stress
Passive fit means the implant-supported framework seats fully and simultaneously on all abutments without inducing mechanical stress in the prosthesis or the implants.
