Both conventional fixed braces and Invisalign are effective in moving and straightening teeth.
One advantage that conventional fixed braces have over Invisalign is its long-standing successful history in correcting misalignment of teeth, whereas Invisalign is comparatively new in the market (about 20~ odd years).
However, Invisalign has gone through tremendous improvement over the years through their investment into research and development. Invisalign is now able to achieve results which are higher in complexity and also achieve results in a shorter time frame. This is greatly supported by the fact that every Invisalign case is submitted through their online software customization tool, which determines each patient's treatment plan. A large database was readily accumulated in a short period of time thanks to the tool (4 million cases at the time of writing), which greatly helped their research.
Fixed braces are a better option for patients who do not exhibit good compliance and discipline. As the name suggests, fixed braces involve brackets that are glued to the teeth. In contrast, Invisalign is a mould of your teeth which can be removed anytime and anywhere. Orthodontists view Invisalign as suitable for a patient when they need minimal disruption to their everyday lives (invisibility, better comfort, less ulceration, minimal disruption to eating habits etc.). However, do note that Invisalign still recommends wearing their trays for 20-22 hours per day.
Both methods require excellent dental hygiene as both increases the possibility of cavity and gum problems. In this aspect, patients with Invisalign would probably fare better as it is easier to clean the Invisalign trays and their teeth, compared to digging under the metal brackets for fixed braces.
Ultimately, deciding which method is best for you requires you to have a consultation with your orthodontist. Sit down and discuss together with your orthodontist what your needs are and they will appropriately personalise treatment for you.
