摘要:

&NA;Ridge preservation is the prevention of the 40% to 60% jawbone atrophy that normally takes place 2 to 3 years postextraction and continues at a rate of 0.25% to 0.5% per year until death. It is achieved by the immediate grafting of the extraction socket with or without the use of an immediate implant. It offers the dentist the ability to preserve the alveolar ridge for future implant and restorative dentistry, to achieve anterior esthetics, and to prevent postoperative pain and bleeding. The practice of ridge preservation involves advanced extraction therapy and replacement therapy. (Implant Dent 2000;9:168‐176)

摘要:

&NA;A procedure using osteotomes and bioactive glass as an alloplastic bone graft material is discussed, and three clinical cases are reviewed. Bioactive glass of a narrow size range (300‐355 &mgr;m) has been shown to be osteoconductive and allows for good integration and regeneration of surrounding bony tissue. We have found this technique to be a predictable method of preparing and placing longer implants in the region of the maxillary premolar region without the need for additional donor site morbidity.

摘要:

&NA;A single appointment fabrication of an emergency overdenture is described. The technique was used in the treatment of a failed implant‐supported fixed bridge that was unable to be reinserted due to fractured components and a lack of passive fit. This technique may also be used for the treatment of a failing natural dentition as well as an implant prosthesis. (Implant Dent 2000;9:183‐187)
