ORE Part 2 Oral Surgery & Extractions 3

Question 1

What splint duration is recommended following lateral luxation of a permanent incisor?

Accepted Answer

4 weeks with a semi-rigid splint

Answer

IADT guidelines recommend a semi-rigid splint for 4 weeks following lateral luxation to allow PDL healing while preventing ankylosis from rigid immobilisation.

Question 2

When should a post-extraction review be arranged for a straightforward lower molar extraction in a healthy adult?

Accepted Answer

Only if the patient is symptomatic or at high risk

Answer

Routine post-extraction review is not always required for uncomplicated extractions in healthy patients; review should be arranged if the patient is symptomatic or has risk factors.

Question 3

What is the recommended approach if inferior alveolar nerve (IAN) injury is detected post-operatively after third molar surgery?

Accepted Answer

Document findings, reassure patient, review at 3 months, refer to oral surgery if no recovery

Answer

IAN injuries should be documented thoroughly, the patient reassured (most recover within weeks), reviewed at 3 months, and referred to an oral and maxillofacial surgeon if there is no improvement.

Question 4

Which flap design is most commonly used for surgical removal of a lower third molar?

Accepted Answer

Ward's (envelope) incision with a distal relieving incision

Answer

The most common approach involves a Ward's envelope incision along the external oblique ridge with a mesial relieving incision, providing adequate access while avoiding key anatomical structures.

Question 5

What is the clinical significance of a displaced root fragment into the maxillary sinus during upper molar extraction?

Accepted Answer

Requires urgent referral to oral and maxillofacial surgery for removal

Answer

A root displaced into the maxillary sinus can cause acute or chronic sinusitis and must be removed by an oral surgeon with appropriate sinus access under specialist care.
