  1. The critical threshold temperature for bone necrosis during implant site preparation is:

    Answer: 47°C

    Bone protein denaturation and cellular necrosis occur at 47°C when sustained for one minute, making this the critical threshold during osteotomy.

  2. Biphasic calcium phosphate (BCP) bone substitutes contain a mixture of:

    Answer: Hydroxyapatite and tricalcium phosphate

    BCP combines hydroxyapatite (slowly resorbing) and beta-tricalcium phosphate (more rapidly resorbing) to balance scaffold longevity with new bone formation.

  3. Autogenous bone grafts are considered the gold standard because they:

    Answer: Provide osteogenesis, osteoinduction, and osteoconduction

    Autogenous bone is the only graft material that provides all three mechanisms—living osteogenic cells, inductive proteins, and a conductive scaffold.

  4. Which implant surface characteristic is measured by contact angle assessment?

    Answer: Surface hydrophilicity/wettability

    Contact angle measurement quantifies how readily water spreads on the implant surface, with lower angles indicating greater hydrophilicity and improved blood clot adhesion.

  5. The torque wrench setting for final abutment screw tightening in most manufacturers' protocols ranges from:

    Answer: 15-35 Ncm

    Most manufacturers recommend 15-35 Ncm for abutment screws, with the specific value torque protocol varying by implant system and screw material.

  6. PEEK (polyether ether ketone) is used as an implant material primarily for:

    Answer: Provisional abutments and healing components

    PEEK's tooth-like modulus of elasticity and radiolucency make it ideal for provisional abutments and healing caps, though it lacks sufficient osseointegration for implant bodies.

  7. Which property of sintered porous titanium scaffolds makes them advantageous for bone augmentation?

    Answer: Interconnected porosity allowing vascular ingrowth

    Interconnected pores (ideally 100-400 µm) allow blood vessel ingrowth and osteoprogenitor cell migration, enabling true bony integration of the scaffold.
