Objectives\u00a0\u00a0<\/b>Dental traumas frequently occur in young children and young adults. The maxillary incisors are the most commonly damaged teeth with a greater risk for central maxillary in\u00adcisors, especially in children with increased overbite and overjet. In avulsions\u2019 treatment of perma\u00adnent teeth, the reimplantation of the same element is the first choice of treatment in most cases.<\/p>\n
How\u00adever, there are contraindications to this therapeutic option, such as: delay of the operation, age, compli\u00adance, the patient\u2019s oral health and the condition of the dental element. A recent therapeutic alternative described by G\u00f6llner et al. is a temporary rehabilitation using TADS pending a future implant in\u00adsertion at the end of growth. In the following study the authors report a case of traumatic avul\u00adsion of a maxillary central incisor rehabilitated using two orthodon\u00adtic mini-screws inserted with a computer-guide technique.<\/p>\n
Materials and methods\u00a0\u00a0<\/b>A 13-year-old male patient arrives at the dental clinic a week after the traumatic avulsion of the upper right central incisor due to a fall off the bi\u00adcycle. A clinical and radiographic ex\u00adamination shows a complete avul\u00adsion of the upper left central incisor and an uncomplicated fracture of the incisal margin of the upper right central incisor, without soft tissues lesions. The cephalometric exam\u00adination highlights a normodivergent skeletal Class III (ANB: -2.1\u00b0; Wits Appraisal: -3.5 mm) with a reduc\u00adtion of overjet and overbite (OB: 1.2 mm; OV: 1.4 mm). Two mini-screws have been using the Easy Driver technique (Uniontech, Parma, Italy).<\/p>\n
Results\u00a0\u00a0<\/b>In this study the authors use two or\u00adthodontic mini-screws and a tempo\u00adrary resin prosthetic element of the frontal incisor. A CBCT has been prescribed to analyze possible frac\u00adtures of the alveolar bone and to plan the computer guided insertion. In this way facilitates the precise and safe insertion of the mini-screws in the anterior hard palate area.<\/p>\n
The two orthodontic mini-screws are placed in a parallel position af\u00adfecting the two cortical bones to have greater stability. The manu\u00adfacturing of a temporary resin pros\u00adthetic element of the frontal incisor fastened to the two mini-screws awaiting an implant-prosthetic re\u00advaluation at the end of growth. The prosthetic rehabilitation of the upper right central incisor is sup\u00adported by the composite resto\u00adration of the incisal edge of the upper left central incisor.<\/p>\n
Conclusions\u00a0\u00a0<\/b>Using this technique, even less ex\u00adperienced operators have the op\u00adportunity to easily insert the mini-screws and to fasten the device during the same appointment avoid\u00ading the riskier manual insertion. The benefits of this temporary treat\u00adment in growing young patients are: simplicity and safety of insertion of mini-screws; aesthetic result of the prosthesis; easy maintenance of proper hygiene; stability (absence of risk of decementation or loss of re\u00adtention in mixed dentition).<\/p>\n
Clinical significance\u00a0\u00a0<\/b>This clinical case shows an easy and fast method to manage a den\u00adtal trauma. This method can be a choice for those patients having low disposable income. Moreover, it is useful in growing patients be\u00adcause it can be adapted to the ver\u00adtical growth of the jawbone.<\/p>\n
