Abstract

Nowadays Er:YAG lasers are employed for bone surgery because of their emission wavelengths of 2.94µm which allows for optimization of material removal rate. Nevertheless, high degrees of tissue carbonization are unavoidable and prevent the process of tissue regeneration. In this work, a femtosecond source with a pulse duration of 350fs was employed to carry a comparative study on ablation efficiency and quality at wavelengths of 1030nm and 515nm. Laser-treated bones were analyzed by optical profilometry, SEM and EDX. Results show that on optimization of the process parameters is necessary to achieve an optimal quality of ablation without tissue carbonization.
