In horizontal bone loss, inflammation spreads through tissue, ending in the ____. In vertical bone loss the inflammation spreads through tissue, ending in the ________. |
Periodontal Ligament, Alveolar Bone |
|
Embeds in the cementum and fans out into the gingival connective tissue and attaches the gingiva to teeth. |
