UNLABELLED
Backround: The aim of this study was to assess changes in bone volume after block bone augmentation and placement of dental implants and further evaluate the aesthetic outcome of the treatment.
MATERIAL AND METHODS
9 patients with atrophied anterior maxilla were included in this study. They received total of 21 implants. Dimensions of the alveolar ridge were measured from cone-beam computed tomography x-rays. The bone level at the implant sites was analysed from intraoral x-rays and the aesthetic outcome was assessed from clinical photographs using a pink aesthetic score (PES) scaling.
RESULTS
The mean gained horizontal bone width at the marginal crest and 5 mm apically was accordingly 2.7mm and 5.0 mm. The mean PES rating was 9.8/14. The survival rate of.
CONCLUSIONS
Reconstruction of the atrophied anterior maxilla with bone blocks and dental implants is a safe procedure with high survival rate and acceptable aesthetic outcome.

背景：本研究的目的是评估块状骨增量及牙种植体植入后骨体积的变化，并进一步评估治疗的美学效果。
材料与方法
本研究纳入了9例上颌前部骨萎缩患者。他们共接受了21颗种植体。牙槽嵴的尺寸通过锥形束计算机断层扫描X线片测量。从口内X线片分析种植体部位的骨水平，并使用粉色美学评分（PES）量表从临床照片评估美学效果。
结果
边缘嵴处及根尖5mm处平均获得的水平骨宽度分别为2.7mm和5.0mm。平均PES评分为9.8/14。
结论
用骨块和牙种植体重建萎缩的上颌前部是一种安全的手术，具有高生存率和可接受的美学效果。
