General heating characteristics for different screw‐post combinations. Based on temperature profile plots (see associated figures), combinations that showed anything more than negligible heating were deemed “not safe”.

Screw Type	Alumina	Post Type Carbon	Insulated Alumina
Alumina	not safe (Fig. 11) significant heating	not safe (Fig. 12) some heating	safe (Fig. 14) negligible heating
Titanium	not safe (Fig. 11) most heating	not safe (Fig. 12) some heating	safe (Fig. 14) negligible heating
