Abstract

論文(Article)

Maintaining of stable occlusal function is one of the most important key to enjoyone's own life.Recently,dental rehabilitation using endosseous implants has been well established treatment modality in the field of prosthetic dentistry.However,there are some cases who can't undergo dental implant treatment because of an inadequate height and width of the alveolar ridge or total loss of bony tissue.For such cases,jaw bone reconstruction is indispensable surgical procedure to enable the implant insertion. Among many techniques,reconstruction with the use of particulate cancellous bone and marrow (PCBM) is characterized by its process of bone formation and remodeling.After PCBM grafting,active new bone formation occurs from osteogenic stem cells followed by bone remodeling that results in incorporation into the recipient bone.This process means that the aim of PCBM transfer is not the graft of osseous tissue but the graft of osteogenic stem cells.In other words,grafting of PCBM is the method of bone regeneration that is based on in vivo tissue engineering.This review introduces the basic and clinical research of the jaw bone reconstruction with iliac PCBM by showing the repair of alveolar bony defect of cleft lip and palate,maxillary sinus floor elevation, alveolar ridge augmentation and mandibular reconstruction.
