What does the term 'torque loss' after final abutment tightening indicate in implant prosthetics?
Answer: Micro-settling of the abutment-implant interface, requiring re-torqueing
Initial torque loss (embedment relaxation) occurs due to micro-settling at the connection interface; re-torqueing after 10 seconds is recommended.
A patient scheduled for implant surgery is found to have an HbA1c of 9.5%. The best course of action is:
Answer: Delay elective implant surgery until glycemic control improves
Poor glycemic control (HbA1c >8%) impairs healing and osseointegration; elective implant surgery should be deferred until control improves.
Which incision design preserves the interdental papilla and is preferred when placing implants adjacent to natural teeth?
Answer: Papilla-sparing incision (paramarginal or intrasulcular with papilla reflection avoided)
Papilla-sparing incisions avoid incising through the papilla to preserve blood supply and soft tissue height adjacent to neighboring teeth.
What is the primary risk of over-preparing (overdrilling) the implant osteotomy site in type IV (very soft) bone?
Answer: Loss of primary stability due to insufficient bone engagement
In soft (type IV) bone, over-preparation removes the limited trabecular bone available, resulting in inadequate primary stability for the implant.
Which post-operative sign is most indicative of implant failure due to infection rather than biomechanical overload?
Answer: Peri-implant radiolucency with suppuration and pain on percussion
Suppuration, pain, and radiographic radiolucency suggest an infectious etiology (peri-implantitis or early failure), distinguishing it from mechanical complications.
The 'one-stage' implant surgical protocol differs from the 'two-stage' protocol in that:
Answer: One-stage keeps the implant transmucosal, avoiding a second uncovering surgery
In the one-stage protocol, a healing abutment is placed at the time of implant surgery, keeping it transmucosal and eliminating the need for a second uncovering procedure.
When using CBCT for implant treatment planning, which measurement is most critical to establish before selecting implant length?
Answer: Available bone height from the crest to the critical anatomical structure
Available bone height measured to the nearest critical structure (IAN, sinus floor, floor of nose) determines the maximum safe implant length.
