Splinting Of Avulsed, Luxated And Root Fractured Teeth

Question 0

Why is the use of long term rigid splinting questionable?

Answer 0

Increased risk of pulpal necrosis and external root resorption

Question 1

Why should teeth be splinted after injury?

Answer 1

To prevent displacement and further injury to the pulp or periodontal ligament during the healing phase

Question 2

How does the use or csp splints and ortho band splints compare to acid etch splints or no splinting?

Answer 2

Greater frequency of pulpal necrosis and pulp canal obliteration

Question 3

How long should a splint be lwft in place according to current guidelines?

Answer 3

3-4 weeks

Question 4

What is the current revommendation for avulsed and replanted teeth?

Answer 4

Functional splint for 7-10 days

Question 5

When may an extended period of splinting be required?

Answer 5

If there has been an extensive loss of marginal bone

Question 6

What is the biological explanation as to why non-splinted teeth had less replacement resorption than rigidly splinted teeth?

Answer 6

Functional stimulation has been shown to prevent and remove areas of replacement resorption probably due to rapid repopulation of necrotic zones in periodontal ligaments with blood vessels and fibroblasts
