Patients may be concerned about the risk of orthodontic appliances damaging the roots. It is important to note that some degree of root resorption occurs in all orthodontic patients, but severe root resorption is rare and unpredictable. A study of 1083 teeth showed that 41.81% of them experienced a reduction in root length after transparent aligner therapy, with only 3.69% experiencing a reduction of more than 20%. Missing or damaged teeth can have a negative impact on dental health, but dental implants can replace these teeth and help to restore oral health.
Root resorption is a natural process that occurs in all orthodontic patients, but it is usually minimal and does not cause any significant damage. However, it is important to monitor the process and take appropriate action if severe root resorption is observed. The root and crown lengths of 1083 teeth were measured using panoramic radiographs at the beginning and end of the transparent aligner therapy. The results showed that 41.81% of the 1083 teeth had a reduction in root length after treatment, with an average of 6.38 ± 2.28 teeth per patient affected by the reduction.
It is important to be aware of the risks associated with orthodontic appliances, such as root damage, but it is also important to remember that severe root resorption is rare and unpredictable. If root resorption is observed, it is best to discontinue treatment and consider other options such as dental implants to restore oral health.
