As dental experts, most dentists find it difficult to select the best aligner sheets for various malocclusions and necessary tooth movements.
Understanding the characteristics and physical properties of various aligner sheets is crucial.
Let’s go over the specifics of each kind of sheet one at a time!
The most recent and well-known aligner sheet is composed of polyurethane polymer, renowned for its quick processing and short wear period.
Now, the question is: Is quick treatment required in every situation?
The answer is no!
PU sheets are incredibly beneficial for executing complex bone shifting and complicated tooth movements.
Polyurethane sheets apply an additional 20% of initial orthodontic forces, facilitating the difficult phase of tooth movement.
Therefore, PU aligner sheets are the ideal solution for rapid complex tooth movement.
Polyurethane sheets have less stress relaxation and are less likely to break or be damaged. These characteristics make it easier to carry out complex tooth movements that demand more power and efficiency.
The shorter wear time of PU is another benefit! Rather than the usual 14 days, each tray is worn for only seven days.
With a very small number of distributors, polyurethane sheets are slightly more expensive than PETG sheets.
It must also be used as soon as unpacked to avoid distortion.
Taglus PU FLEX is the ideal polyurethane sheet, with high-end efficiency and excellent outcome. It has masking to prevent damage to the sheets.
Glycol-infused PET sheet is another aligner sheet offered on the market.
PETG sheets are bestowed with glycol and thus very comfortable to wear and acceptable.
Because PETG sheets include glycol, they are acceptable and highly comfortable.
The PETG sheets are highly effective at retaining the generated teeth gaps in place because they produce a steady, continuous force used in multiplane, stable movements.
The PETG sheets possess exceptional optical clarity and justify a 14-day wear period per tray.
However, PETG sheets are not able to execute the complex tooth movements, break easily as compared to the Polyurethane sheet and also retain elasticity for three days only.
It’s a perfect choice for retainers and in the second stage of tooth movement.
The proper use of an aligner sheet makes it very feasible to get the desired optimal results in the required time frame.
