Final answer:
Heat tolerant dental instruments are usually sterilized using autoclaving, which is a moist-heat sterilization technique. Autoclaves raise temperatures above the boiling point of water to sterilize the instruments effectively.
Step-by-step explanation:
Heat tolerant dental instruments are usually sterilized using moist-heat sterilization techniques such as autoclaving. Autoclaves rely on raising temperatures above the boiling point of water to sterilize the instruments without damaging them. Autoclaves are considered the most effective method of sterilization in laboratory and clinical settings.
