Treatment options following single-rooted tooth removal: a literature review and proposed hierarchy of treatment selection.

BACKGROUND: Alveolar bone changes following tooth extraction have been well documented and have given rise to a number of treatment approaches. Included in these approaches are placement of various grafting materials, immediate implant placement, and a combination of both.
METHODS: A review of all pertinent literature discussing regenerative therapy at the time of tooth extraction or immediate implant placement with or without concomitant regenerative therapy was carried out.
RESULTS: A clinically-based hierarchy of treatment selection following extraction of single rooted teeth is proposed, based upon the available literature and clinical experience. The role of patient phenotype is considered.
CONCLUSION: Utilization of the proposed hierarchy of treatment selection affords a logical framework within which to predictably treat a variety of patients.
