Clear aligner treatment uses custom-made, removable orthodontic trays to move teeth towards planned positions. Existing tooth positions, bite relationships and gum health are assessed together. Aligners may be a less noticeable option, but they are not suitable on their own for every orthodontic problem.
Before treatment, photographs, impressions and necessary imaging are obtained. The digital plan helps assess tooth movements. The on-screen design does not guarantee an identical biological response or outcome. Small composite attachments, elastics or other aids may be necessary for certain movements.
Aligners are used in the prescribed sequence, and reviews monitor how well movements follow the plan. Wearing time and replacement intervals are explained individually. Inadequate use may prevent movement from progressing as planned. New impressions and additional aligners may be needed. Total duration depends on the extent of movement and adherence to treatment.
Aligner cleaning and regular dental care are important. Pressure, sensitivity or temporary speech changes may occur in the early days. Retention is planned after treatment to preserve tooth positions. Care and follow-up beyond the active aligner phase must therefore also be considered.
The clear aligner approach
Clear aligners is a term used for transparent orthodontic trays. These are removable appliances made according to a specific plan for tooth movement. In clear aligner treatment, which uses appliances also referred to as invisible or transparent aligners, changes in tooth alignment are planned gradually through a sequence of trays. Today, this planning is carried out digitally after an intraoral scan, and the aligners are manufactured using technological equipment. Each tray does not move all teeth by the same amount at the same time.
Suitability is assessed according to the position of the teeth and the nature of the movements required. The appearance of the front teeth is not the only consideration; the way the back teeth bite together and the tissues supporting the teeth are also important. In some cases, fixed orthodontic appliances or other methods may be more suitable.
The aligners must be worn for the prescribed number of hours each day, review appointments must be attended, and oral hygiene must be maintained. Being removable does not mean that treatment can be carried out without professional supervision. Aligner fit and tooth movement are assessed regularly; the plan may be adjusted if necessary.
