SINUS BONE GRAFT WITHOUT GRAFT MATERIALS: A CASE REPORT 骨移植材を使用しない上顎洞骨移植：症例報告 katosika.dental We had believed that sinus bone graft needs living autogenous bone or other graft materials not alive  for resisting air pressure that gradually resorbs the bottom the sinus as a result. However, can the fact that needs some graft materials be true? Dr. Jensen wrote that …….in 1997, I observed a strange phenomenon in a maxillary fracture patient. A unilateral ossification of the maxillary antrum occurred following a Le Fort III fracture that had been treated the year before. I wondered how trauma around the antrum due to an impacted maxilla and the inferiorly displaced orbital rim could lead an ossified maxillary sinus…………This unusual finding remained a mystery to me for many years…….He (Phil Boyne) found that preservation elevated sinus membrane created a confined space in which bone had the potential to form. 1) Until now, clinicians had found that maxillary sinus h...

Gold standard of bone graft might be autogenous bone graft. When we perform the sinus bone graft procedure with autogenous, much autogenous bone might be needed. If the donor bone is supplied from extra-oral donor site such as ilium, fibula and parietal region,  the patient will be admitted to hospital for high morbidity. So this option may be difficult to be done in private practice. Even so from intra-oral region as chin or ramus, there may be much burden (but many cases needs this region donor).     Circumstances of maxillary sinus  is   considered to be unique for its closing one sealed with un-brokened shneiderian membrane and air pressure. The success points of sinus bone graft can be the circumstances sealed that we made in the surgery and manipulation against air pressure.  A case we report is sinus bone graft with only   Ceratite [ ○ !R], a bioceramic composed of hydroxyapatite and tricalciumphosphate within blood. Autogenous bone ...

Impact of donor site for bone graft harvesting for dental implants on health-related and oral health-related quality of life Authors:  Daniel R. Reissmann , Björn Dietze, Michael Vogeler, Rainer Schmelzeisen, Guido Heydecke Keywords:  autologous bone graft harvesting;health-related quality of life;morbidity;oral health-related quality of life Abstract (要約） Objectives（目的） To assess and compare changes in health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) after bone graft harvesting for dental implants with respect to the donor site. ドナー部位からみた歯科インプラントに関する骨移植後の健康に関連した生活の質 (HRQoL) における変化と口腔健康に関連した生活の質(OHRQoL)の査定と比較。 Material and methods（材料と方法） Autologous bone grafts were harvested in a consecutive sample of 23 patients (mean age: 46.1 years; 52% female) either from an intra-oral (IO; N  = 8; chin, ascending ramus, buttress region) or an extra-oral (EO; N  = 15; anterior iliac crest) d...

Procera (NobelBiocare AB, Gothenburg Sweden) all ceramic restorations are used in prosthetic  restorations for patients toward high level esthetic demands in the world. Advantages of this restorations are : 1) achieving of highly esthetic results, 2) high strength, 3) Non-allergy, 4)  Saving laboratory time with CADCAM, 5) Easy remanufacturing with PC data preservation. 6) Three years manufacture's guarantee. Disadvantages are: 1) Sometimes tipping, 2) Cost, 3) depending on technicians experiences. The patient desire was to correct the irregular edge and black spot of interdental papilla in the central incisors after periodontal therapy.The case history of 39 years female is indicated below. プロセラ（ノーベルバイオケアー、イエーテポリ、スェーデン）オールセラミック修復は高度な審美的結果を要求する患者のための補綴修復として世界中で使用されている。その利点をあげると　 １）高度な審美的要求に応えられる。２）強靭さ丈夫さ　３）アレルギーの心配がない　４）CADCAM使用により技工時間が少ない　５）パソコンにデータが保存されている為に再製が容易。６）3年の会社保証期間　などである。欠点は１）時々チップする　２）値段　３）制作する技工士の腕に依存する、などである。 これは, 上顎中切歯の切端の不揃いと歯周治療後にできた歯冠乳頭のブ...
