Why are lower 8's extracted by directing lingually?

Directing the extraction of lower 8's (mandibular third molars) lingually is primarily due to the presence of thinner bone in this area. This approach helps to minimize the risk of damaging surrounding structures while facilitating a more efficient extraction process.

The lingual bone covering the roots of the lower wisdom teeth is often less dense than the buccal bone, making it easier to mobilize the tooth during extraction. By directing the extraction lingually, practitioners can effectively navigate the tooth removal with less resistance from the surrounding bone, ultimately promoting a smoother extraction experience.

When extractions are performed with consideration of the anatomy and structure surrounding the teeth, it helps improve outcomes and reduce complications. This understanding is essential for anyone involved in dental practices, particularly those specializing in oral surgery or extractions.
