Crown Lengthening Clinical Trial
Official title:
Laser Verses Conventional Circumferential Supracrestal Fiberotomy in Orthodontic Extrusion for Crown Lengthening: A Randomized Controlled Clinical Trial
The aim of this study is to the evaluate the stability of the amount of healthy tooth structure exposed after laser versus conventional technique of fiberotomy during orthodontic extrusion.
Parallel groups, two arm, superiority Randomized Controlled Clinical Trial, with 1:1 allocation. PICO: Population: patients with endodontically treated teeth and short clinical crown that require crown lengthening in the esthetic zone Intervention: laser fiberotomy with orthodontic extrusion Control: conventional fiberotomy using blade with orthodontic extrusion Outcomes: Primary outcome: Stability of the mount of healthy tooth structure exposed. Secondary outcomes: - Stability of gingival Margin reference. - Stability of the alveolar bone. - Rate of tooth extrusion. - Sulcus depth. - Pain Time: 8 weeks after retention ;
