READ ABSTRACT Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction and can be a significant problem in implant and restorative dentistry. Postextraction maintenance of the alveolar ridge minimizes residual ridge resorption and allows placement of an implant that satisfies both esthetic and functional criteria. Guided bone-regeneration techniques and the use of bone-replacement materials have been shown to enhance socket healing and potentially modify the resorption process. The prime indication for socket preservation is the prevention of alveolar-bone and soft-tissue collapse, which would cause unacceptable prosthesis esthetics. This review describes the rationale behind socket preservation, and the various techniques and materials used for extraction site grafting.

READ LEARNING OBJECTIVES

• explain the rationale behind preservation of the socket after tooth extraction and its importance for proper pontic design and ideal intraosseous implant placement
• discuss the process of extraction socket healing and the mechanism of socket preservation
• describe the various techniques used for socket preservation, using either bone grafts and membranes (alone or in combination) and the other materials and techniques used for the process

READ ABSTRACT The three “Rules of 10” for treatment planning dental implant therapy in the edentulous mandible are designed to improve the success of both the endosseous implants and the prosthesis. These “rules” acknowledge and provide a method to control the mechanical environment, addressing factors affecting implant and prosthesis longevity, including magnitude of forces, resistance of the prosthesis against these forces, and the biology of bone and its ability to respond to loading environments. The rules specify that for any IRO or ISFP, there must be a minimum of 10 mm of alveolar dimension (inferior/superior) and a minimum of 10 mm of interocclusal (restorative) dimension measured from the soft-tissue ridge crest to the occlusal plane. Additionally, for an ISFP, the anterior/posterior distribution of implants must be greater than 10 mm. This article provides support in the literature for these rules and illustrates their application in the treatment of mandibular edentulism.

READ LEARNING OBJECTIVES

• identify factors that affect the ongevity of implants and prostheses used to treat mandibular edentulism
• explain the specifics of the Rules of 10 guidelines for treatment planning implant therapy in the edentulous mandible
• discuss application of the Rules of 10
