| 中文摘要 | 齒槽骨高度或寬度的不足是植體放置在理想位置的主要障礙。解剖構造和生物學方面的限制,使得垂直高度的增加比水平寬度要更困難。本篇研究的目的,是評估使用階段性骨引導再生術於垂直骨脊增高的臨床效果。本研究使用錐狀射束電腦斷層,分析47位下顎後牙區有垂直骨脊缺損的病患[13位男性和34位女性,平均年紀為45.36±10.49歲(26~68歲)],術前與術後骨脊高度與寬度的變化,手術使用不可吸再生膜(ePTFE),搭配顆粒狀異種骨或人工合成骨粉。錐狀電腦斷層照射時間點為術前和補骨後至少七個月,總共49個無牙區,植入89根植體,結果平均垂直高度增加2.6±0.8mm而水平寬度增加6.4±0.8mm。若排除有再生膜早期暴露的病例,平均垂直高度增加3.3±0.6mm,而水平寬度增加6.5±0.5mm;有再生膜暴露的位置,則平均垂直高度增加2.4±0.5mm,水平寬度增加6.4±0.9mm。有無再生膜暴露對於水平骨增加沒有顯著差異,但是對垂直骨增加有顯著差異。總結來說,合併使用不可吸收ePTFE再生膜和顆粒狀異種骨或人工合成骨粉,對於增高或增寬牙床骨,都是一個有效的治療選擇。 |
| 英文摘要 | Alveolar bone deficiency is the main local obstacle of placing dental implant in an ideal position, both in horizontal and vertical directions. Between them, anatomical and biological limitations make reconstructing vertical ridge height much more difficult than the horizontal one. The purpose of this study is to evaluate the clinical efficacy of vertical ridge augmentation, using staged-approach guided bone regeneration (GBR) surgical technique, by measuring the vertical and horizontal bone gain on cone beam computed tomography (CBCT) scans. Forty-seven consecutive patients (13men and 34 women) with 49 vertical ridge deficiencies in the posterior mandible were enrolled in this study, ranging in age from 26 to 68 years (mean 45.36± 10.49 years). A two-stage surgery was performed with non-resorbable ePTFE membranes combined with particulate xenograft or alloplast bone graft. CBCT scans were taken preoperatively and at least 7 months after ridge augmentation. Forty-nine edentulous sites were augmented and 89 implants were inserted. Mean vertical bone gain (VBG) was 2.6±0.8 mm (1.4~5.1 mm) and mean horizontal bone gain (HBG) was 6.4±0.8 mm (4.7~7.7 mm). When the cases with membrane exposure were excluded, the mean bone gain was 3.3± 0.6 mm in vertical and 6.5± 0.5 mm in horizontal direction. The mean VBG was 2.4 ± 0.5 mm and HBG was 6.4 ± 0.9 mm in membrane exposure sites. No statistically significant differences were found between membrane exposure and horizontal bone gain (p =0.639). However, membrane exposure had a statistically significant effect on vertical bone gain (p < 0.05). In conclusion, the combination of non-resorbable membrane and particulate xenograft or alloplast bone graft was an effective treatment option for bone augmentation before implant placement. |
