Final answer:
The air abrasion technique uses high-pressure delivery of abrasive particles to remove tooth structure.
Step-by-step explanation:
The air abrasion technique uses high-pressure delivery of abrasive particles through a small probe to remove tooth structure. These abrasive particles are usually smaller than 0.05 mm and can include materials such as pumice, calcium carbonate, kaolinite, quartz, soapstone, or talc. The high-pressure delivery of these particles allows for precise and minimally invasive removal of tooth structure.
