Diode laser debonding of ceramic brackets

Laser-Aided Ceramic Bracket Debonding: A Comprehensive Review

“…12 The relatively small size, weight, power requirement, and lower cost make diode laser a practical addition to clinical practice. 13 In other studies, the advantages of producing less thermal effects made the Er-YAG The debonding times of 5 or 6 s were 2 or 3 s shorter per tooth compared with debonding using a traditional heater.…”

“…Using experimentally produced 4 META/MMA-TBB resin orthodontic adhesives containing 30 and 40 wt% thermal expansion microcapsules and different lasing durations (4, 5 and 6 seconds), Saito et al 11 found the bond strength of adhesive containing 40 wt% microcapsules was sufficient for orthodontic treatment and decreased significantly to 0.40-0.48-fold (4.6 5.5 MPa) by CO 2 laser irradiation for 5 or 6 seconds versus the non-laser groups. Investigating the effect of a diode laser on shear bond strength of ceramic brackets, Feldon et al 13 and Almohaimeed et al 18 found that diode laser could significantly decrease shear bond strength of monocrystalline bracket and pre-coated ceramic brackets, respectively. Oztoprak et al, 14 Nalbantgil et al, 15 Nalbantgil et al 19 and Tozlu et al 16 investigated the effect of Er:YAG laser on debonding.…”

“…They reported that the intrapulpal temperature was below the benchmark of 5.5°C. Feldon et al 13 and Ivanov et al 21 debonded both kinds of monocrystalline and polycrystalline ceramic brackets with a diode laser. Feldon et al 13 reported that the mean increases in pulp chamber temperature The diode laser was ineffective with polycrystalline brackets and efficient with monocrystalline brackets in significantly (P < 0.05) decreasing the shear bond strength.…”

Diode laser irradiation significantly lowered the force required for monocrystalline brackets to be removed without increasing pulp temperature significantly.…”

“…An important consideration in pulpal temperature increase is the type of bracket to be removed. Feldon et al 13 debonded monocrystalline and polycrystalline ceramic brackets with a diode laser and reported that the mean increases in pulp chamber temperature for all lased groups were statistically significant and less than the 5.5°C increase threshold. It was not significantly different from the 1.8°C standard except for monocrystalline brackets irradiated by 5 W/cm 2 in which the mean pulp chamber increases significantly above the 1.8°C standard, but not significantly different from the 5.5°C standard.…”
