What does 'platform switching' refer to in implant dentistry?
Answer: Using a narrower abutment diameter than the implant platform diameter
Platform switching uses an abutment with a smaller diameter than the implant platform to shift the microgap inward and preserve crestal bone.
A Morse taper implant-abutment connection is characterized by:
Answer: A friction-fit conical connection
Morse taper connections use a conical friction-fit interface that provides strong mechanical stability and reduces micro-movement at the junction.
What is the function of the implant cover screw?
Answer: Seals the implant during submerged healing
The cover screw closes the implant fixture during the submerged (two-stage) healing protocol to protect the internal connection.
Which type of implant connection features a six-sided external protrusion for torque transfer?
Answer: External hex
External hex connections have a hexagonal protrusion on top of the implant that fits into the abutment to resist rotational forces.
What is the recommended torque value range for tightening most implant abutment screws?
Answer: 15–35 Ncm
Most manufacturers recommend abutment screw torque of 15–35 Ncm to ensure proper seating without stripping or fatigue fracture.
Zirconia implants compared to titanium implants offer which primary advantage?
Answer: Better esthetics in thin gingival biotypes
Zirconia's tooth-colored appearance eliminates the gray shadow sometimes visible through thin gum tissue, making it preferred for esthetic zones.
