Abstract

Polycaprolactone has exhibited expediency as a biomaterial for bone regenerative procedures preclinically. The present report of the 2 clinical cases in the posterior maxilla is the first to describe clinical application of a customized 3D-printed polycaprolactone mesh for alveolar ridge augmentation. Two patients needing extensive ridge augmentation procedures for dental implant therapy were selected. Polycaprolactone meshes were virtually designed, 3D printed, and applied in combination with a xenogeneic bone substitute. Cone-beam computerized tomography was taken preoperatively, immediately after the surgery, and 1.5-2 years after the delivery of implant prostheses. The serial cone-beam computerized tomography images were superimposed to measure the augmented height and width at 1-mm increments from the implant platform to 3 mm apically. After 2 years, the mean [maximum, minimum] bone gain was 6.05 [8.64, 2.85] mm vertically and 7.77 [10.03, 6.18] mm horizontally at 1 mm below the implant platform. From immediately postoperative to 2 years, there was 14% reduction of augmented ridged height and 24% reduction of augmented width at 1 mm below the platform. All implants placed in augmented sites were successfully maintained until 2 years. The customized polycaprolactone mesh might be a viable material for ridge augmentation in the atrophic posterior maxilla. This needs to be confirmed through randomized controlled clinical trials in future studies.

使用定制的三维打印聚己内酯网在萎缩的后上颌骨上进行垂直和水平嵴隆起:病例报告。
聚己内酯作为一种生物材料,在临床前的骨再生手术中已显示出其便利性。本报告中的两个上颌骨后部临床病例首次描述了定制的三维打印聚己内酯网用于牙槽嵴增量的临床应用。报告选取了两名需要进行大面积牙槽嵴增高手术以进行种植牙治疗的患者。对聚己内酯网格进行了虚拟设计、三维打印,并将其与异种骨替代物结合使用。分别在术前、术后和植入假体后 1.5 至 2 年进行锥形束计算机断层扫描。将连续的锥形束计算机断层扫描图像进行叠加,以测量从种植体平台到根尖 3 毫米处每 1 毫米增量的增高和增宽。2 年后,在种植体平台下 1 毫米处,平均[最大,最小]垂直骨增量为 6.05 [8.64, 2.85] 毫米,水平骨增量为 7.77 [10.03, 6.18] 毫米。从术后即刻到 2 年期间,平台下 1 毫米处的增高脊高度减少了 14%,增高宽度减少了 24%。所有植入增高部位的种植体都成功地维持了 2 年。定制的聚己内酯网可能是一种可行的材料,可用于萎缩性上颌后牙槽嵴增高术。这需要在今后的研究中通过随机对照临床试验来证实。
