Treatment of patients after trauma requires the cooperation of specialists from various fields of dentistry. Comprehensive treatment aims to best preserve or restore the function and aesthetics of the stomatognathic system. A particular problem is the fracture of tooth crowns at the cervical level in patients of developmental age. Depending on the size of the injury, the patient may undergo conservative treatment – splinting and observation. If conservative treatment fails, the tooth may require root canal treatment. When there is not an adequate amount of tissue to ensure a tight prosthetic reconstruction, the tooth may be subjected to clinical crown lengthening, orthodontic or surgical extrusion. If the tooth has no prospects, it needs to be removed. This is associated with significant bone growth disorders in patients during development. Implant treatment can be performed only when bone growth is completed. The aim of the study was to describe the diagnostic and therapeutic procedure in a juvenile patient after a trauma that resulted in teeth damage in the maxilla. The treatment required cooperation between specialists of oral surgery, endodontics, prosthetics and orthodontics.
