Dental Implants Patient Assessment & Treatment Planning 2

Question 1

A patient's keratinized tissue width around an implant site should ideally be at least:

Accepted Answer

2 mm

Answer

At least 2 mm of keratinized tissue around implants helps resist recession, facilitates hygiene, and improves long-term peri-implant health.

Question 2

The diagnostic wax-up or digital smile design in implant planning primarily helps to:

Accepted Answer

Visualize the final esthetic outcome and guide surgical stent fabrication

Answer

A diagnostic wax-up simulates the final restoration to communicate esthetics with the patient and create a surgical guide.

Question 3

Occlusal overload in implant-supported restorations can lead to:

Accepted Answer

Crestal bone loss and implant failure

Answer

Excessive occlusal forces exceed the bone-implant interface's tolerance, causing microfractures, bone resorption, and ultimately implant failure.

Question 4

Which measurement is most important when assessing the mesiodistal space for a single tooth implant?

Accepted Answer

Width of the edentulous space

Answer

Adequate mesiodistal width (typically ≥7 mm for a standard implant) ensures proper implant placement without encroaching on adjacent tooth roots.

Question 5

Inter-arch space (restorative space) of at least how much is typically required for an implant-supported crown?

Accepted Answer

5–7 mm

Answer

A minimum of 5–7 mm of vertical restorative space is needed to accommodate the abutment height plus the crown material.
