Diastema

A space between two teeth

How well did you know this?

Perfectly

Consequence of not respecting natural morphology when closing a diastema

Perfectly

Define black triangle

Papilla relies on underlying bone for structure, so loss of bone –> loss of papilla –> black triangle

Perfectly

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

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
