Scaling Human Bone Properties with PMMA to Optimize Drilling Conditions During Dental Implant Surgery

Dental implant surgery is an effective alternative for replacement of missing teeth. The success of the implant depends on how well the bone heals around the implant. However, the excessive heat generated during drilling may create a necrotic zone in the drilled area, which prevents the growth of bone around the implant. Using human bone for the many experiments needed to investigate factors that affect heat generation during drilling, it is impracticable to obtain human bone so we substitute a material used as bone cement for the last 40 years by dental surgeons. This paper reports results obtained by drilling Poly Methyl Methacrylate (PMMA) under different conditions and discusses how these results are scaled to represent human bone.
