What is the location of interproximal bone in relation to buccal and lingual bone in normal alveolar bone morphology?

The interproximal bone, which is the bone situated between the roots of adjacent teeth, is typically located at a coronal position relative to the buccal and lingual bone in healthy alveolar bone morphology. In a normal dentition, this placement supports the interproximal contact area and helps in maintaining stability and integrity of the teeth as well as the alveolar bone.

In a healthy periodontal state, the interproximal bone must be coronal to the buccal and lingual bony plates to properly accommodate the roots of the teeth and the surrounding soft tissues. This coronal positioning prevents the risk of periodontal disease and maintains overall oral health, as it ensures that adequate bone height is present for support. Other choices do not accurately reflect the typical anatomical arrangement of alveolar bone. For example, if the interproximal bone were at an apical level, it could indicate periodontal destruction or advanced bone loss. Thus, recognizing the coronal position of the interproximal bone is critical for understanding healthy periodontal anatomy.
