AI Article Synopsis

  • Tooth extraction typically leads to reduced height and width of the alveolar ridge, complicating future prosthetic or implant procedures.
  • Effective site preservation techniques, such as using bone grafts or materials with or without membranes, can help maintain ridge dimensions after extraction.
  • The paper discusses the necessity and rationale for site preservation to improve outcomes for implants and conventional restorations, while addressing differing opinions on the need for such procedures.

Article Abstract

The extraction of a tooth normally results in the loss of ridge height and width. Often, clinicians are faced with the management of edentulous sites that are less than optimal for prosthetic rehabilitation and implant restoration due to considerable alveolar ridge collapse after tooth removal. Site preservation using bone grafts or substitutes with and without a membrane maintain ridge dimensions and contours. However, some clinicians believe that such procedures are over-treatment. This paper reviews the concepts and indications for site preservation following tooth extraction for the purpose of facilitating implant placement and conventional prosthetic restoration.
