Black Triangles

Black triangles can happen with any method of alignment, including traditional braces. This is a natural consequence of alignment correction, so it can't always be avoided.

If a gap remains after the aligners come off, additional orthodontic treatment may be required to close it. Here are a few solutions that might work for your patient:

• In the case of black triangles, perform IPR at the point of contact to allow the affected teeth to come together.
• Restorative therapy might be in order to fill smaller gaps caused by insufficient interdental gingiva.
• Reconstructive periodontal therapy, also known as "periodontal plastic surgery" or "gingival graft", may also be considered to increase interdental papilla height and volume to fill the black triangle void.
• The digital power chain is a valuable technique that eliminates gaps by bringing the teeth closer together.
