PURPOSE The aim of this pig model study was to verify whether the use of devices (surgical templates) or procedures (flapless or flap) of guided surgery may cause a potentially pathologic increase of temperature during the bone preparation. MATERIALS AND METHODS In this in vitro study, pig ribs with mean cortical thickness of 1.90 mm were used. Open-flap(More)
