Question 2

How would you manage a prominent frenum?

Answer 2

1. take a PA to exclude the presence of a supernumerary
2. in developing dentition a diastema of less than 3mm does not warrant any treatment
3. I’m developing dentition if diastems more than 3mm and lateral present then could consider an appliance to approximate the centrals providing enough space for laterals and canines to erupt: need to be careful roots do not impeded on any crowns
4. Distally tilted crowns can consider using a removable appliance but if you need full bodily movement then need fixed
5. Needs long term retention!!!
