The reduction of the size of conventional dental implant to
mini-implant leads to a lot of benefits. Nevertheless, orthodontic
mini-implants have shown more clinical failures than conventional
dental implants submitted to orthodontic loads [16], with increase in
fracture incidence and mobility of the mini-implants after the healing
period [17]. In order to overcome the increased fracture incidence,
cpTi was gradually replaced by Ti-6Al-4 V alloy as the material base of
the mini-implant, due to the better mechanical properties of the alloy
[15,18].
