Dental Implants Surgical Procedures & Techniques 2

Question 1

The osteotome technique for sinus floor elevation (crestal approach/Summers technique) is best indicated when:

Accepted Answer

Residual bone height is 6–8 mm, requiring 2–4 mm of lift

Answer

The crestal sinus lift is most predictable when 6–8 mm of residual bone remains and only a modest elevation (2–4 mm) is needed simultaneously with implant placement.

Question 2

Immediate implant placement (Type 1) means the implant is placed:

Accepted Answer

Immediately at time of tooth extraction

Answer

Type 1 (immediate) placement occurs on the same day as extraction into the fresh socket, reducing total treatment time.

Question 3

The 'jumping distance' in immediate implant placement refers to:

Accepted Answer

The gap between the implant surface and the socket wall

Answer

The jumping distance is the horizontal gap between the implant body and the buccal/lingual socket walls, which must be filled with graft material.

Question 4

Resonance frequency analysis (RFA) measures implant stability using the unit:

Accepted Answer

Implant stability quotient (ISQ)

Answer

RFA measures implant stability on an ISQ scale from 1–100; higher values indicate greater stiffness and primary stability.

Question 5

Which post-operative instruction is most critical after implant surgery to prevent infection?

Accepted Answer

Chlorhexidine rinse and prescribed antibiotics as directed

Answer

Chlorhexidine rinse reduces bacterial load at the surgical site while antibiotics prevent post-operative infection during the critical early healing phase.
