Additive manufacturing of PLA to mimic the thrust force of mandibular bone during drilling

Edentulism is a condition that results in the partial or total loss of teeth. It may lead to problems during chewing and be cause self-isolation low self-esteem. can resolved both with removable prostheses (dentures) fixed implants, latter being more efficient. The installation implant involves real surgical operation which jaw/mandibular bone drilled through special drill. One main cautions surgeon must have not sever nerves drilling. Given composition different each person, drilling thrust force variable controlling its movement sometimes complicated. Therefore, able test on dummy reduce number errors. Additive manufacturing high degree customization ability produce objects almost no geometrical limitations could provide required features realize dummy. In this work, properties samples made PLA Fused Filament Fabrication (FFF) were studied. designed mimic bone. Specifically, thin, hard, denser outer layer 25% internal filling adopted. dental drill properly connected collaborative robot.
