Dental Implants Surgical Procedures & Techniques 3

Question 1

Lateral window sinus augmentation (Caldwell-Luc approach) is typically indicated when residual bone height is:

Accepted Answer

Less than 4–5 mm

Answer

When less than 4–5 mm of subantral bone remains, a lateral window approach is needed to place adequate graft material before or during implant placement.

Question 2

Piezoelectric surgery (piezosurgery) during implant site preparation offers the advantage of:

Accepted Answer

Selective cutting of mineralized tissue while sparing soft tissue

Answer

Ultrasonic piezo devices cut bone with minimal heat and vibration while avoiding laceration of nerves, vessels, and the sinus membrane.

Question 3

The 'tent pole' technique using implants or titanium mesh in ridge augmentation is designed to:

Accepted Answer

Create and maintain a protected space for bone regeneration

Answer

Rigid titanium mesh or implants tent the membrane to prevent collapse into the defect, maintaining the space needed for new bone formation.

Question 4

Immediate loading of a dental implant requires a minimum insertion torque of at least:

Accepted Answer

35 Ncm

Answer

A minimum insertion torque of 35 Ncm is generally required to ensure sufficient primary stability to withstand functional loading without implant micro-movement.

Question 5

Ridge splitting (ridge expansion) technique is used to treat:

Accepted Answer

Horizontal knife-edge ridge deficiency

Answer

Ridge splitting expands a thin but tall alveolar ridge by splitting the cortical plates apart, allowing simultaneous or staged implant placement.
