Osseous resective surgery is most appropriate for periodontal sites with...?

Severe bone loss
Early to moderate bone loss
No bone loss
Horizontal bone loss only

The correct answer is: Early to moderate bone loss

Osseous resective surgery is performed for treating periodontal sites with an inadequate bone support. This option refers to early to moderate bone loss, which is a range that indicates a certain level of bone loss without it being too severe. Therefore, it is the most appropriate option as it indicates the proper amount of bone loss that would require this type of surgery. Option A, severe bone loss, would actually require a more extensive type of surgery, such as periodontal regeneration. Option C, no bone loss, does not require any type of bone removal, making this option incorrect. Lastly, option D, horizontal bone loss only, does not specify the severity or extent of bone loss, which makes it an insufficient answer.
