• Status: Unknown
• Phase: N/A

Summary

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.

Detailed description

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

Conditions

• Circumferential Supracrestal Fiberotomy
• Orthodontic Extrusion
• Crown Lengthening

Interventions

Type	Name	Description
PROCEDURE	conventional circumferential supracrestal fiberotomy	The amount of tooth that need to be extruded will be measured Bonding brackets slot 0,022"x0.028" Roth prescription on piggyback for the tooth with (0.016". x 0.022 ") stainless steel main arch wire and 0.0014" nickel titanium auxiliary. • Fiberotomy After 2 days of bonding, local anaesthetic solution will be administrated. The depth of the fibrotomy should be equal to the amount of tooth that need to be extruded. supracrustal fibrotomy will be performed using 15 c blade (Carvalho, Bauer et al. 2006)
PROCEDURE	laser circumferential supracrestal fiberotomy	* The amount of tooth that need to be extruded will be measured * Bonding brackets slot 0,022"x0.028" Roth prescription * piggyback for the tooth with (0.016". x 0.022 ") stainless steel main arch wire and 0.0014" nickel titanium auxiliary. • Fiberotomy * After 2 days of bonding, local anaesthetic solution will be administrated. * The depth of the fibrotomy should be equal to the amount of tooth that need to be extruded. * A diode laser of 980 nm wavelength will be used The laser tip will be inserted, and incision will be extended around tooth circumference with the system configured to a continuous wave with the movement of the laser tip in an up and down stroking movement The laser tip will be moved in a circumferential manner taking care that all the fibers are lysed.
