Which restoration type is the standard of care for replacing a single missing tooth with an implant?
Answer: Single implant crown
A single implant crown uses one implant fixture with an abutment and crown to replace one missing tooth without affecting adjacent teeth.
What is the purpose of an implant impression coping during the prosthetic phase of treatment?
Answer: To transfer the precise three-dimensional position of the implant to a working cast
An impression coping captures and transfers the exact three-dimensional position and angulation of the implant to a working cast for accurate prosthetic fabrication.
When evaluating a zirconia implant crown before final cementation, which factor is most critical to verify?
Answer: Internal fit accuracy and marginal adaptation
Verifying internal fit and marginal adaptation ensures the zirconia crown seats properly without gaps that could harbor bacteria or compromise long-term success.
What is an implant analog used for in the dental laboratory?
Answer: It replicates the implant position in the working cast to allow laboratory fabrication of the prosthesis
An implant analog is a replica of the implant fixture that is embedded in the working cast so the dental laboratory can fabricate the abutment and crown with accurate positioning.
Which occlusal scheme is generally recommended for implant-supported restorations to minimize potentially damaging lateral forces?
Answer: Mutually protected (canine-guided) occlusion
Mutually protected occlusion is preferred for implant restorations because canine guidance during lateral excursions minimizes lateral forces on posterior implants.
What distinguishes a multi-unit abutment from a standard single-unit abutment?
Answer: It connects multiple implants to a shared prosthetic framework in full-arch cases
A multi-unit abutment is designed to join multiple implants to one prosthetic framework, commonly used in full-arch fixed implant restorations such as All-on-4.
