Q

Consequence of not respecting natural morphology when closing a diastema

A

Q

What may cause plaque accumulation on the root? What is the consequence?

A

Groove/depression/concavity on root

May compromise a patient’s ability to maintain good oral hygiene (can’t access)

In time, may lead to an inflammatory process and eventual loss of alveolar bone
