*3.3. Overheating Exposure Time*

3.3.1. Bone Window 1

#### ΔT > 10 ◦C

In bone window 1, the average exposure times under ΔT > 10 ◦C at the zirconia implants were 39.06 s for machined (all 8 of 8 in group 1), 28.10 s for sandblasted (11 of 11 in group 2), and then decreased to 20.37 s for sandblasted etched implants (10 of 11 in group 3). The average exposure times under ΔT >10 ◦C at the titanium implants were 22.49 s for machined (7 of 15 in group 4), 23.05 s for sandblasted (6 of 15 in group 5), and then decreased to 17.45 s for sandblasted etched implants (2 of 15 in group 6). None of the tested implants experienced a temperature increase of more than 10 ◦C over a period of more than 60 s.
