His most cited paper, Histologic evaluation of new attachment apparatus formation in humans.

The tooth is supported in bone by an attachment apparatus, known as the periodontium, which interacts with the root.

Primary occlusal trauma will occur when there is a normal periodontal attachment apparatus and, thus, no periodontal disease.

This, in turn, can lead to destruction of the gingival tissues, which may progress to destruction of the periodontal attachment apparatus.

The supracrestal attachment apparatus is composed of two layers: the coronal junctional epithelium and the more apical gingival connective tissue fibers.

In primary occlusal trauma, the etiology, or cause, of the mobility was the excessive force being applied to a tooth with a normal attachment apparatus, otherwise known as a periodontally-uninvolved tooth.

The technique employs a thin membrane to channel cells that can promote the growth of a new attachment apparatus toward the surface of the root of the tooth, while screening out other cells.

Enamel Matrix Protein These agents not only help improve wound healing but also stimulate regeneration of the lost bone, periodontal ligament and cementum restoring the complete periodontal attachment apparatus.

They are also attached to the gingival (gum) tissue that covers the alveolar bone by an attachment apparatus; because this attachment exists superficial to the crest, or height, of the alveolar bone, it is termed the supracrestal attachment apparatus.
