Laser light energy has been shown in other studies to degrade resins by thermal softening, thermal ablation, or photoablation. If this technology could be successfully applied to bracket debonding, fracturing of both bracket and enamel during debonding might be eliminated. Both polycrystalline alumina and single crystal alumina (sapphire) ceramic orthodontic brackets were bonded to the labial surfaces of lower deciduous bovine incisor teeth with the acid-etch technique as currently practiced in… CONTINUE READING
