Fixed Anterior Alignment – Case Study: CW

Fixed Anterior Alignment by Dr Nick Simon

Dr Nick Simon is a former IAS teacher and Mentor. He was a delegate on the first cohort of the Advanced Fixed Course taught by Prof Ross Hobson. My patient felt like she needed orthodontics as a child but had missed out. She presented with severe crowding, which detracted from her smile and left her low on confidence.

KEY STAGES IN TREATMENT PROGRESS

Plan
Upper and lower fixed appliances

Extraction all 1st premolars

Upper Nance appliance and Lower Lingual Arch. High anchorage demands due to inclination of canines.

Upper and lower fixed retainers, removable retainers

Review Retainers

Approach

Bond up. Minimal engagement of 012 Niti archwire to upper and lower incisors to prevent proclination of the incisors. Lace back 1st molars and 2nd premolars each quadrant. Retraction of canines with powerchain from 2nd premolars. Upper Nance and lower Lingual Arch.

Once the canines were sufficiently retracted, the upper and lower incisors were ligated into the brackets.

The upper Nance and Lower Lingual Arch were removed once the case moved into 19 x 25 Niti and the lower centreline had been established.

Conclusion

The IAS advanced course was the best course I have completed. It gave me the ability to treat a whole range of orthodontic cases that previously I would have referred. This case is just one example of that. I would encourage anyone who has had some experience with fixed braces to join this pathway, you will not regret it. The mentoring is excellent and you will feel confident that you have the support and advice both during and after the course. That is so important to us GDP’s..to make us feel safe, plus you’ll  make great friends along the way.
