Class II Deep Bite — A Mini-Implant Story

A previously treated Class II case with 4 extractions and a deep bite — re-corrected using braces with mini-implants (TADs) to achieve an ideal overjet and overbite.

What is it?

The Profile Tells the Story — Lips Apart to Lips Sealed

A lateral cephalometric X-ray records the soft-tissue profile from the side. The red line traces the lip and chin position. Before treatment the upper teeth were forwardly placed, so the lips were strained apart and could not seal at rest. After retraction, the lips meet naturally and the profile balances.

BEFORE — Lips Apart Cephalometric X-ray before treatment showing lips apart and a protruded soft-tissue profile traced in red
Lip incompetence • Protruded profile
AFTER — Lips Sealed Cephalometric X-ray after treatment showing lips sealed and a balanced soft-tissue profile traced in red
Lips seal at rest • Balanced profile
Red line = soft-tissue profile trace (nose tip → lips → chin)

What the red line shows

In the before X-ray the red profile line bulges outward at the lips — the lips have to strain to close over forwardly placed teeth. After the teeth were retracted with braces and mini-implants, the line runs smoothly from the nose through relaxed, sealed lips to a well-positioned chin. This is the objective, radiographic proof that the bite correction changed not only the teeth, but the lip seal and the whole profile.

In the Patient's Own Words

The numbers and X-rays tell one side of the story. Here is the other.
