The margin of the buccal wall is shifted apically by approximately 2 mm over the 8 weeks of healing, as indicated by the yellow arrow. Bone loss is greater in the buccal wall than in the lingual wall during socket healing for several reasons. First, the crestal portion of the buccal bone wall, especially in the anterior region, is occupied by bundle bone. As mentioned earlier, bundle bone is a tooth-dependent tissue that completely resorbs after tooth extraction. On the contrary, the lingual or palatal socket wall is typically composed of less bundle bone. Also, the lingual bone wall of the socket is wider than the buccal wall.
