Abstract
A pontic device for preserving soft tissue in a tooth-extraction site includes a generally curved apical end. The apical end has a first perimeter and is configured to rest in a tooth extraction socket and substantially conform to soft tissue of a tooth-extraction site immediately after a tooth has been extracted. The pontic device further includes an opposing, generally concave coronal end. The coronal end has a second perimeter that is configured to substantially correspond to and form a seal with gingival tissue surrounding the tooth-extraction site. The coronal end is configured to receive a tooth-shaped coronal pontic portion to form a final restoration.
