Which prosthetic component connects an implant body to the overlying crown or prosthesis and is available in stock or custom forms?
Answer: Abutment
The abutment is the intermediary component that attaches to the implant body and provides support and retention for the prosthetic crown or bridge.
A patient with bruxism is receiving an implant-supported restoration. Which design modification BEST protects the prosthetic components?
Answer: Fabricate a night guard and use screw-retained restorations for retrievability
A night guard reduces parafunctional forces, and screw retention allows easy access if screws loosen or fracture occurs in high-stress patients.
What is the purpose of 'platform switching' in implant design?
Answer: Using a narrower abutment on a wider implant platform to preserve crestal bone
Platform switching positions the abutment-implant microgap away from the bone crest, which is associated with reduced crestal bone resorption.
When using an analog in a poured master cast for implant work, the analog represents which component?
Answer: The implant body as it exists in the patient's jaw
The implant analog is a lab replica of the implant body that is embedded in the master cast to replicate the implant's position in the patient's bone.
A technician notices a visible dark line at the gingival margin of a PFM implant crown due to the metal abutment showing through thin tissue. The BEST solution for future cases in this esthetic zone is to:
Answer: Switch to a ceramic or zirconia abutment
A ceramic or zirconia abutment eliminates the grayish shadow transmitted through thin gingival tissue, which cannot be corrected by porcelain layering alone.
Which parameter defines the 'prosthetic table' in implant planning and affects the type of restoration possible?
Answer: The distance from the implant platform to the occlusal plane
The prosthetic table refers to the vertical distance from the implant platform to the opposing occlusal surface, which determines the available space for abutment height and restoration thickness.
In digital implant prosthetics, which file format is universally used to transfer scan data between intraoral scanners and CAD/CAM software?
Answer: STL (Standard Tessellation Language)
STL (Standard Tessellation Language) is the universal open file format for sharing three-dimensional surface scan data across digital dental platforms.
