【摘要】：目的：應(yīng)用錐形束CT(cone beam computed tomography CBCT)對(duì)牙槽嵴裂植骨(ABG)患者術(shù)后患者不同時(shí)間段骨密度(BMD)及骨高度觀測(cè),了解骨愈合穩(wěn)定時(shí)期及植骨區(qū)唇腭側(cè)骨量變化,為進(jìn)行后序治療時(shí)機(jī)提供參考。 方法：選取20名單側(cè)完全性牙槽突裂患者,常規(guī)行牙槽嵴裂髂骨移植術(shù),術(shù)后3個(gè)月、6個(gè)月復(fù)查,ProMax3D檢查獲得原始數(shù)據(jù)以DICOM格式存放,圖像輸入Simplant11.04軟件重建。測(cè)量術(shù)后3個(gè)月、6及健側(cè)骨密度值,結(jié)果用Hounsfieldunits (HU)表示；根據(jù)改良Bergand分類法對(duì)術(shù)后3個(gè)月、6個(gè)月植骨區(qū)唇、腭側(cè)骨高度分別進(jìn)行分類,并與全景片分類對(duì)比。 結(jié)果：術(shù)后3個(gè)月平均骨密度(BMD)(385.086±73.572HU)與術(shù)后6個(gè)月(356.380±78.297HU),無(wú)明顯差異(P0.05)；均小于健側(cè)(475.475±65.826HU)(P0.05)。術(shù)后3個(gè)月唇、腭側(cè)骨高度分類與同月全景片分類比較有差異(P0.05)；術(shù)后6個(gè)月唇、腭側(cè)骨高度分類與同月全景片分類比較有差異(P0.05)；術(shù)后3個(gè)月唇、腭側(cè)及全景片骨高度分類分別與術(shù)后6個(gè)月唇、腭側(cè)及全景片骨高度分類比較有差異(P0.05) 結(jié)論：本研究中牙槽突裂植骨術(shù)后3個(gè)月與6個(gè)月骨密度均值無(wú)明顯差異；唇側(cè)與腭側(cè)分類不同,且術(shù)后6個(gè)月骨高度分類較術(shù)后3個(gè)月低。說(shuō)明骨吸收持續(xù)存在,術(shù)后3個(gè)月骨密度穩(wěn)定,提示臨床醫(yī)生可在術(shù)后3個(gè)月進(jìn)行后序治療；骨移植區(qū)不同部位骨量不同,唇側(cè)或者腭側(cè)存在全景片不易發(fā)現(xiàn)的骨凹陷, CBCT可客觀評(píng)價(jià)植骨區(qū)骨質(zhì)量,對(duì)手術(shù)評(píng)價(jià)及指導(dǎo)后序治療有臨床應(yīng)用價(jià)值。
[Abstract]:Objective: to observe the bone mineral density (BMD) and bone height in patients with alveolar cleft bone graft (ABG) at different time after operation by using conical bundle CT(cone beam computed tomography CBCT), and to understand the changes of bone mass in the labiopalatine side during the stable period of bone healing and bone grafting. To provide a reference for the timing of post-sequence therapy. Methods: 20 patients with complete alveolar cleft were selected and underwent alveolar crest iliac bone transplantation. After 3 months and 6 months, the original data were stored in DICOM format and the images were reconstructed by Simplant11.04 software. Bone mineral density (BMD) was measured 3 months after operation, and the results were expressed by Hounsfieldunits. According to the modified Bergand classification, the lip and palatal bone height were classified in 3 months and 6 months after operation, and compared with panoramic radiographs. Results: there was no significant difference in BMD between 3 months after operation (385.086 鹵73.572HUU) and 6 months after operation (356.380 鹵78.297HUU). There were significant differences in the classification of lip and palatine bone height between the same month and the same month after operation (P0.05), the classification of palatine lateral bone height in 6 months after operation was different from that in the same month (P0.05), and the third month after operation was compared with that of panoramic film (P0.05). The classification of bone height of palatal side and panoramic film was different from that of lip, palatine side and panoramic bone height of 6 months after operation (P0.05). Conclusion: in this study, there was no significant difference in BMD between 3 months and 6 months after alveolar fissure grafting, and the classification of lip and palate was different, and the classification of bone height at 6 months after operation was lower than that at 3 months after operation. This indicates that bone resorption persists and bone mineral density is stable at 3 months after operation, suggesting that clinicians can carry out posterior treatment at 3 months after operation, and bone mass in different parts of bone graft area is different. CBCT can objectively evaluate the quality of bone in the bone graft area, and it has clinical application value in the evaluation of surgery and the guidance of post-sequence therapy.
