Clin Oral Implants Res:新型图像处理技术有助开展精准种植治疗

近日,上海交通大学医学院附属第九人民医院口腔种植科的研究成果“A novel semiautomatic segmentation protocol to evaluate guided bone regeneration outcomes:a pilot randomized, controlled clinical trial”在口腔种植领域权威杂志《Clinical Oral Implants Research》发表。

在过去的20年间,植骨(GBR)技术被广泛应用于种植领域。牙科CT(CBCT)作为一种低辐射剂量的三维检测手段,被认为是GBR术后疗效评价的重要手段。然而,CBCT受口内金属种植体影响,会产生金属伪影和射束硬化现象,很大程度上影响了影像学分析准确性。

该研究原创性的提出了新型图像处理技术,运用形态学插值法算法去除某些金属伪影干扰严重的层面,有效避免逐层手动分割的主观偏移,在国际上首次实现牙种植体周围骨粉形态的精准分割,而且显着提高了测量的稳定性,有助于辅助口腔内植骨术后效果评价,具备极高的科研价值和临床推广前景,为制定结果导向的牙槽骨缺损新分类奠定了方法学基础。

该系列研究将造福众多临床需要进行植骨的种植患者,有助于开展精准种植治疗,提高植骨效果,减少手术创伤,避免无效植骨,维持种植牙的长期功能和美观。
