背景：随着口腔种植修复技术的快速发展与适应证的不断扩大，角度基台的应用逐渐增多，后牙区作为口腔咬合的负重区，种植体承载的颌力大，对后牙区角度基台的评价具有更现实的临床指导意义。<br> 目的：评价角度基台在后牙区种植义齿的短期临床效果。<br> 方法：选择2008年1月至2013年1月来诊接受后牙区种植的114例患者，共植入175颗ITI种植体并完成单冠修复。根据基台的应用分为角度基台组与直基台组。测量两组修复后6个月、2年种植义齿牙周探诊深度、改良菌斑指数、改良龈沟出血指数与种植体周围年均骨吸收量，采用寿命表法计算两组种植义齿的5年累积存留率。<br> 结果与结论：直基台与角度基台的种植义齿在牙周探诊深度、改良菌斑指数、改良龈沟出血指数方面比较差异均无显著性意义(P>0.05)。种植体周围年均骨吸收量差异也均无显著性意义(P>0.05)。15°与20°角度基台的5年累积存留率为95.6%，直基台的5年累积存留率为96.4%。结果显示种植义齿的基台角度与种植体周围软组织健康及骨吸收程度无相关性，15°与20°的角度基台在后牙区种植义齿可以取得较好的临床修复效果，长期效果有待于进一步观察。
揹景：隨著口腔種植脩複技術的快速髮展與適應證的不斷擴大，角度基檯的應用逐漸增多，後牙區作為口腔咬閤的負重區，種植體承載的頜力大，對後牙區角度基檯的評價具有更現實的臨床指導意義。<br> 目的：評價角度基檯在後牙區種植義齒的短期臨床效果。<br> 方法：選擇2008年1月至2013年1月來診接受後牙區種植的114例患者，共植入175顆ITI種植體併完成單冠脩複。根據基檯的應用分為角度基檯組與直基檯組。測量兩組脩複後6箇月、2年種植義齒牙週探診深度、改良菌斑指數、改良齦溝齣血指數與種植體週圍年均骨吸收量，採用壽命錶法計算兩組種植義齒的5年纍積存留率。<br> 結果與結論：直基檯與角度基檯的種植義齒在牙週探診深度、改良菌斑指數、改良齦溝齣血指數方麵比較差異均無顯著性意義(P>0.05)。種植體週圍年均骨吸收量差異也均無顯著性意義(P>0.05)。15°與20°角度基檯的5年纍積存留率為95.6%，直基檯的5年纍積存留率為96.4%。結果顯示種植義齒的基檯角度與種植體週圍軟組織健康及骨吸收程度無相關性，15°與20°的角度基檯在後牙區種植義齒可以取得較好的臨床脩複效果，長期效果有待于進一步觀察。

BACKGROUND:As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value. <br> OBJECTIVE:To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region. <br> METHODS:From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis. <br> RESULTS AND CONCLUSION:There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.
