Preliminary study on the osseointegration effects of contactless automated implant cavity preparation via femtosecond laser ablation

Year: 2021

Type: article

Abstract: Microrobots were used to control the femtosecond laser ablation of bone tissues to prepare implant cavities for dental implant surgery. The method was optimized through depth-of-cut experiments of ex vivo rabbit femurs, and the optimized method was used to prepare implant cavities on the left femurs of eight live rabbits. A power of 10 W and a scanning rate of 4000 mm/s were found to be optimal. After seven days of osteoinduction, the expression of collagen type I was significantly higher in the experimental group than in the control group (manually drilled implant cavities). The bone-implant contacts of the experimental group at 4 and 8 weeks were 9.65% and 23.08%, respectively.
