Dental implant has become one of the important option for completely or partially edentulous patients, But it is challenging to reconstruct the severely atrophic ridge. Insufficient bone volume could restrict to place the wide and long implant and because of excessive interocclusal clearance, improper prosthetics could be produced. In this case bone augmentation for implant dentistry is necessary procedure to improve the insufficient bone volume. Therefore, bone augmentation or GBR is the most important procedure for successful implant placement and for ideal crown- root ratio. There are various bone augmentation techniques have been introduced recently; like block bone graft, distraction osteogenesis, inlay graft, onlay graft, etc.... In severe bucco-lingual resorption area, ridge splitting is the first choice of the treatment, because it provides a place for implantation and also has compaction effect. This technique may be indicated for sharp mandible and maxillary ridges in patients whose bone quantity is inadequate for primary stabilization. We report that the clinical experience of bone augmentation using ridge splitting technique in bucco-lingual bone resorption area.

According to the increase in use of implants in clinical dentistry, new kinds of complications happen. Complications that can happen during implant placement are bleeding, nerve injury, jaw fracture, fenestration of maxillary sinus or nasal cavity, dehiscence, fenestration, injury of adjacent tooth. And complications that can happen after implant operation are infection, bleeding, hematoma, chronic sinusitis, peri-implantitis. Problems that are confronted during implant placement happen by inadequate preoperative treatment plan, inadequate consideration about individual anatomic difference, inadequate operation process and lack of experience of clinician. It is important that clinicians consider possible complications in advance and make a comprehensive treatment plan. We report the patient who was happened ramus fracture during block bone harvesting from ramus of severely atrophic mandible, the patient who came to emergency ward due to postoperative swelling and bleeding and the patient whose implant was migrated to maxillary sinus with a review of literature.

Objective : This is to report the criteria of success of intraoral distraction osteogenesis for alveolar augmentation in the severely atrophied alveolar defects through clinical result of 2 cases. Subjects and Methods : Anterior segmental osteotomy was performed and alveolar distractors (Martin and Leibinger, Germany) were applied each in 2 patients with severely defected anterior maxillary area. The osteomized alveolar segments were distracted by 1mm a day after latency period. After the consolidation period implants were installed with removal of distractor. The implants were evaluated clinically and radiographically. Results : In Case I, the distracted bone was directed to the palatal side, and another augmentation treatment - block bone graft, guided bone regeneration - was needed. In Case II, the successful alveolar bone augmentation was achieved. Dental implant was placed on distracted alveolar bone, and showed good osseointegration and good function without any complication. Conclusion : Distraction osteogenesis can be a good choice for alveolar ridge augmentation of severely atrophied ridges. However, the anterior esthetic prosthetics relies on the control of the vector, the kind of distractor, the healing capacity of patient and the etiology of atrophy. Therefore another study of each category would be needed.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.
