Orthodontic Treatment for a Canting Occlusal Plane and Protruding Teeth in a Person in Their 50s with Invisalign Lite?

Hello

When one side appears lower and the other side appears higher from the front, making the occlusal plane look tilted, this is called canting.

A quick way to correct canting with Invisalign is to place orthodontic mini-screws on the lower side and use elastics.

I’ll show you how results were achieved with Invisalign Lite, a limited program for partial orthodontic treatment.

This patient came in last June to improve the alignment of the front teeth.

They were stylish and elegant, belying their age in their 50s.

They had originally been looking into laminate treatment, but after being told that the teeth would need to be shaved down, they changed their mind and came in for orthodontic treatment.

A black triangle caused by gum recession can be seen in the center of the lower front teeth.

Because the right-side teeth are lower and the left-side teeth are higher, the overall alignment looks tilted from the front.

The molar bite is not bad.

The two front teeth are protruded.

The lower teeth are more crooked than the upper teeth.

Since the molar bite was fairly good, we set the treatment period at about 10 months and recommended Invisalign Lite with interproximal reduction.

However, to clearly improve the tilted occlusal plane within 10 months, it is better to place orthodontic screws and apply elastic force as well.

The treatment goal was set as improving the alignment and correcting the canting.

After wearing all 14 appliances in the first set for 5 months from August to December, this is the result.

Elastics were hooked so that they crossed over the Invisalign appliance between the blue arrows, actively intruding the right canine area.

To pursue further alignment improvement and other goals, a new set was made, and treatment was completed after wearing the additional appliances from January to May 2025.

The midline is well aligned, and the black triangle between the lower front teeth has decreased.

If the bite is not good, treatment is not finished.

Now let’s compare before and after treatment.

The total treatment period was 10 months.

The improvement in the axis of the tilted lower front teeth is noticeable.

Neat alignment and

The tilted occlusal plane has improved. In addition, the clean smile line stands out.

Now that the buck teeth have been corrected, the overall image looks more refined, doesn’t it?

I hope this post was helpful for those in their 50s or middle age who are hesitant because they think orthodontic treatment will take a long time.
