Abstract
Dental trauma is an important public health problem due to high prevalence and associated limitations. The external impact accounting for trauma may result in different injury types to teeth and supporting structures. This paper describes a clinical case of tooth trauma in an 8-year-old patient exhibiting the displacement of three permanent teeth with open root apexes. Although the traumatic impact resulted in two injury types to teeth and supporting tissues (lateral luxation and alveolar bone fracture), the therapeutic approach was the same in both situations. The bone and teeth were repositioned by digital pressure, stabilized by semirigid splint, and followed up at every week. After six weeks, the splint was removed. At that moment, the clinical and radiographic findings indicated normal soft/hard tissues and absence of pulp/periodontal pathologies. At the fifth year of follow-up, the treatment success of the case was confirmed, although it has been observed that all lower incisors exhibited pulp obliteration as a consequence of the dental trauma.

Summary
Dental trauma is an important public health problem, due to high prevalence, especially among children and teenagers [1]. Lateral luxation is the term used to describe tooth displacement towards a direction different from axially [4], followed by alveolar bone fracture in only one side of the alveolar bone (either labial or lingual/palatal). If both alveolar socket sides have been fractured, the injury should be classified as alveolar fracture, characterized by the involvement of multiple teeth and alveolar process mobility with movement as a unit of the displaced segment [5]. Considering that the literature has reported few cases of lateral luxations and alveolar fractures in young permanent teeth, the aim of this study was to report the association of these two trauma types in permanent teeth with open apexes, in which it was possible to perform immediate treatment and 5-year follow-up
