Case selection is critical when starting out with clear aligners.
It is best to start with cases that are appropriate to your skill and experience level. These are often simpler cases, involving crowding, spacing or basic aesthetic concerns that do not require a change to the occlusion and typically have a projected treatment length of 6 to 12 months.
So what cases should you avoid?
Avoid taking anterior open bite cases. Often times you have to fix the underlying etiology first otherwise the problem will keep recurring.
Do not attempt to do class II and class III cases unless you have done many cases. But if you are going to attempt them, ensure that wisdom teeth have been removed so you have space. Not just erupted, but actually removed. Make sure you have Cephalometric X-ray and you have orthodontist coverage. There are too many complications involved that might get a GP into trouble trying to attempt these cases.
Finally, avoid doing severe posterior crossbite cases in adults. Often times, there will be a functional shift or some other issue that will complicate the case.
