The Use of Spectral Domain Optical Coherence Tomography in Orthodontics

Optical coherence tomography is a new noninvasive investigation method with various applications in dentistry and orthodontics respectively. The intra-oral OCT investigation opens a totally new perspective on the investigation of orthodontic bonding. Polymeric orthodontic brackets (Damon Clear) were bonded on the teeth of the upper arch of a patient following the manufacturer instructions with a light-curing orthodontic adhesive (Blugloo). After bonding the teeth were examined by spectral OCT in order to examine the interface formed by the enamel, orthodontic resin and the bracket. Several images were obtained. Intra-oral OCT is a method of great potential and real benefits in elaborating a prognosis on the clinical durability of bonded polymeric brackets.
