Soft and comfortable, it lasts all day without irritation or slipping. Perfect for sensitive skin too. Thus, it is unlikely that damage to a nerve is due to a simple 'cut'. It is more likely that these nerve injuries incorporate a combination of mechanical injuries (sectioning, stretching, crushing), chemical nerve injuries and ischaemic injuries providing a complex therapeutic challenge.

Histological changes after tooth injury have also been studied. In a prospective study of 68 teeth in 17 patients, Ahmed et al. 14 intentionally injured premolars using a temporary skeletal anchorage device, scheduling them for extraction. They presented the repair process of injury in histological sections, showing that 70% of all premolars exhibited good cementum repair. The effect of the proximity of the screw to the root, the extent or process of healing according to the extent of damage or miniscrew existence, and the prognosis of the injured teeth and/or invading miniscrews have been studied well in animals such as dogs and minipigs 10, 15, 16, 17, 18, 19, 20, 21, 22.

The patients complained only of a few clinical symptoms, even when the implant injured the adjacent natural teeth. Four patients complained of symptoms, and three of them were belonging to group I (directly invasion by the implant). Immediately after surgery, one patient with the implant in the maxillary right first premolar area complained of tenderness on percussion of the maxillary right canine, which had already been endodontically treated. However, the symptom disappeared after several days. Another patient in group II complained of tooth discomfort after surgery and underwent RCT with signs of pulp necrosis. Yet another patient complained of minute tooth discomfort after surgery, and intentional replantation was performed five years later. The last patient reported intermittent inconvenience during mastication with the tooth which had undergone RCT one month after loading. Eventually, the tooth was extracted three years and three months later with discomfort. Hembree, M., Buschang, P. H., Carrillo, R., Spears, R. & Rossouw, P. E.

However, to determine the clinical prognosis of tooth-implant injury, reports of orthodontic miniscrew on the effect of tooth-screw injury can be cited. Orthodontic miniscrews have been used extensively based on the concept of absolute anchorage by the user-friendly easy placement of small-sized screw 10. However, because they are blindly placed in the inter-radicular space, trauma to natural teeth can be a major cause of failure. Thus, some clinical studies on the prognosis of natural tooth roots invaded by miniscrews have been published. Clinical studies of root injuries showed positive results. A 5-year retrospective study Borah and Ashmead 11 showed a very low incidence of root impingement (0.47%) by 2340 transfixation screws in 387 patients with facial fractures. The impinged teeth remained intact and did not require extraction. Another retrospective study reported 1.5% iatrogenic injury to roots during intermaxillary fixation for mandibular fractures. All scratched roots remained vital and root canal perforated teeth were treated endodontically later 12. In a prospective study of patients with mandibular fractures, the incidence of clinically significant damage appeared to be low, although approximately 27.1 % of the 232 screws had damaged the roots 13.Jahangiri, L., Hessamfar, R. & Ricci, J.
