In cases like these, the patients are looking for a dramatic improvement of both the teeth and face.

Take this teenager, her upper and lower lips are protruding. The nasolabial angle is an acceptable 90 degrees, but this is because the nose is upturned and the upper lip sticks out.

She had mildly proclined upper and lower teeth and her lip seal was strained due to hyperactivity of the Mentalis chin muscle.

We agreed to remove the UR4, UL4, LR4 and LL4. This would allow retraction of the front upper and lower 6 teeth and allow the lips to become more relaxed.

The teenager was at boarding school and so the teeth were extracted over 2 visits during the school holidays. Attachments were bonded and she went off to her studies.

She was told to wear the aligners 20 hrs a day and to change them every 10 days. No elastics, TADS or aligner cut out were required.

We did a single review at half term.

Approximately 11 months she returned for a review at the end of the aligners.

There were some minor refinements to do to the occlusion. So we carried out a new Itero scan and took photographs.

Refinement aligners were ordered and fitted 2 weeks later.

Treatment time would be 1.25 years in total with only 2-3 review appointments in-between.

The facial changes were dramatic however.

The face is slimmer, the lips are more relaxed, with the lower lip more so. She will complete the refinements and we will then provide her with 3 upper and 3 lower retainers to retain the occlusion. #invisalign #clear braces

Teeth can develop in many ways and sometimes an abnormal formation can cause occlusal/visual problems.

Dens in dente is an extra cusp formation usually on the incisors, which can interfere with the bite or cause tooth drift. The Dens in dente or talon cusp can be made of enamel, dentine and even nerve tissue.

It looks like a bump and sometimes you can feel it with your tongue. Most people grow up with them and think of them as normal.

They rarely are a massive dental problem.

Dental anomalies are rare and usually of a genetic nature or a disruption during tooth development, such as chicken pox or measles.

The case above shows the forward drift of the UL1 as the lower teeth bite onto the talon cusp, this can also be called an increased overjet.

The patient had a close/deep bite with a narrow arch and prominent UR1 and UL1.

Sometimes the teeth drift due to clenching, which can cause muscle forces to compress the back teeth, moving the front teeth forward, this is called arch collapse.

We advised Invisalign aligners with some minor recontouring of the UL1 incisor.

The lady wore Invisalign trays for about 9 months to expand the dental arch and bring in the upper incisors. The aligners were changed every 2 weeks. The lower teeth were also moved downwards to create space (deep bite reduction).

Patient was happy with straightened front teeth and widened arch.

Tooth whitening was done and the patient received 6 Vivera retainers that so far have lasted 10 years.

Not all patients have had the benefit of orthodontic treatment, and as they get older the problem gets worse.

Sometimes teeth have been orthodontically treated but without adequate retention, orthodontic relapse occurs.

The protrusion of upper teeth can be from tongue, thumb or even lower lip forces and this can create an unfavourable profile.

In this young lady we have a normal nasolabial angle but an increased upper E-line measurement, meaning that the upper lip protrudes out. protrusion. This can be from a longer upper jaw or a shorter lower jaw (asymmetric growth) but it can also be from upper teeth protruding outwards.

Sometimes the lower lip gets caught behind the upper front teeth and can cause protrusion.

This case study shows a young lady who did not have orthodontic treatment and she was not happy with dental appearance or the lip profile.

The only way to reduce the overjet was to remove upper premolar teeth. Nothing else would give a better result without also lower jaw surgery, which we normally do not recommend.

We agreed to do Invisalign with 2 upper teeth extractions.

We had 39 upper and 22 lower aligners, and the patient changed her aligners every 10 days.

After about 1 year we carried out a refinement scan for some new aligners; 11 in total.

The large overjet was greatly reduced to within 2mm and the patient was very happy.

We discussed using Invisalign retainers, that are rotated every 4 months, to stop them from stretching.

The upper lip profile has been relaxed and the patient can comfortably close her lips together. A great result with such a simple technique.

Many patients have narrow dental arches from thumb sucking or clenching their teeth. The facial muscles create forces that will compress the teeth, narrowing the dental arch and cause dental crowding.

The teeth may begin to overlap, rotate or even protrude.

Teeth out o their natural positions are more prone to damage from trauma or tooth wear.

Sometimes you may notice one front tooth is shorter than the other.

Simply by moving the teeth back to their original positions will recreate the space and solve the crowding issue.

This Invisalign case was a 28 year old student who had severe upper and lower crowding and a missing tooth.

We used Invisalign to expand the dental arch and move the teeth back to their original positions, using the missing tooth space.

It took 15 months of treatment and the patient attended every 8 weeks.

At the end we provided 6 Invisalign retainers and tooth whitening as well.

The 3 pairs of retainers are rotated every 4 months which keeps the teeth locked in their final positions.
