Fixed Orthodontic Treatment in a Child Patient with Dentoalveolar Fracture: A Case Report

Abstract

The incidence of dentoalveolar fracture in children is high about 18% because they are often active, lack of body coordination, and immature mental. The dentoalveolar fractures treatment to the children differs from adults, because of the immature bone structure. The purpose of this study is to investigate the treatment of dentoalveolar fracture in child patient using fixed orthodontic appliance. A 15-year-old boy treated with braces caused by malocclusion class 1 Angle type 1. The child suffers from dentoalveolar fracture of the mandibular anterior tooth and mandibular alveolar bone injury after a motorcycle accident. Fortunately, the patient was using an orthodontic fixed appliance that served as a splinting so that severe damage could be prevented. Treatment: the wound was cleaned by betadine antiseptic solution, and braces bonding on the labial of anterior teeth. The lingual region was splinted with wire as 0.7 SS combined with composite resin to make splinting stronger. The patient was given 500mg amoxicillin and 500mg ibuprofen. Wire SS 0.016 is indicated to have superior strength, and the strength remains a support in fixed orthodontic therapy because the stainless steel alloys are of "18-8" austenitic type contain chromium (7-25%), Nickel (8-25% ) and Carbon (1-2%). Chromium in this stainless steel alloy customs a thin oxide layer which blocks the diffusion of oxygen into the alloy and allows the corrosion resistance of the alloy. Stainless steel is introduced for the use of creating appliances. Archwires have high stiffness, low springiness, corrosion resistance, low range and good formability. These wires are often less expensive than the other ones and they can be readily used as archwires in an orthodontic treatment and splinting as well. After two months of splinting treatment, the tooth position approximately back to normal; there was unification alveolar bone in the radiographic evaluation. Dentoalveolar fracture treatment is to restore the teeth and alveolar bone in order that dentoalveolar structure to function properly, and aesthetic function is achieved.
