Abstract

本实用新型涉及一种应用于口腔医疗的假体，尤其是一种下颌骨修复体，包括下颌体、延伸板、牙种植体，下颌体和延伸板为一体式结构，延伸板位于下颌体的侧面上，牙种植体安装在下颌体的上方，延伸板固定在患者正常的下颌骨上。本实用新型提供了的下颌骨个体化修复体只需通过一两次手术即可完整地修复患者下颌骨的缺损或畸形，且能够牢固地固定在患者面部，不易脱落或移动；本实用新型提供了的下颌骨个体化修复体还设置有活动连接的牙种植体，可以通过在牙种植体上安装义齿，有效恢复了患者的咀嚼功能。

Description

一种下颌骨个体化修复体
技术领域
本实用新型涉及一种应用于口腔医疗的假体，尤其是一种下颌骨修复体。
背景技术
    因肿瘤切除、外伤及炎症等所致的下颌骨缺损不可避免地会导致不同程度的颜面畸形与功能障碍，需通过修复手段恢复其连续性、外形与功能。常用的修复方法是将各种骨代用品或者下颌骨修复体植入等，但应用中常存在以下问题：一、常见的骨代用品或下颌骨修复体上常没有设置专门用于安装义齿的牙种植体，后期义齿修复困难，咀嚼功能恢复差；二、常见的骨代用品或下颌骨修复体与正常的下颌骨连接不牢固，且连接后血流不畅；三、手术时间较长、次数多等。
实用新型内容
为解决上述问题，本实用新型提供了一种下颌骨个体化修复体，优选钛合金制成，包括下颌体、延伸板、牙种植体，下颌体和延伸板为一体式结构，延伸板位于下颌体的侧面上，牙种植体安装在下颌体的上方，延伸板固定在患者正常的下颌骨上。优选地，下颌体上设置有螺孔，牙种植体通过螺纹与下颌体连接。
下颌体的高度为15毫米至25毫米之间，下颌体和延伸板上设置有若干个镂空的孔，以保证修复体安装到患者正常的下颌骨上后，血脉能够保持通畅。
通过上述技术方案的实现，本实用新型提供了的下颌骨个体化修复体只需通过一两次手术即可完整地修复患者下颌骨的缺损或畸形，且能够牢固地固定在患者面部，不易脱落或移动；本实用新型提供了的下颌骨个体化修复体还设置有活动连接的牙种植体，可以通过在牙种植体上安装义齿，有效恢复了患者的咀嚼功能。
附图说明
图1为本本实用新型提供了的下颌骨个体化修复体的结构图。
具体实施方式
    如图1所示，一种下颌骨个体化修复体，由钛合金制成，包括下颌体1、延伸板2、牙种植体3，下颌体1和延伸板2为一体式结构，延伸板1位于下颌体2的侧面上，延伸板2的一侧固定在患者正常的下颌骨上；下颌体1的上方设置有螺孔，牙种植体3通过螺纹与下颌体1连接；下颌体1的高度为20毫米，下颌体1和延伸板2上设置有若干个大小不一的镂空的圆孔4，以保证修复体安装到患者正常的下颌骨上后，血脉能够保持通畅。
