Description

基于3D打印的牙槽骨内骨外种植修复桥架
技术领域
本发明涉及医用支架技术领域，尤其涉及一种基于3D打印的牙槽骨内骨外种植修复桥架。
背景技术
牙槽骨是全身唯一有牙齿附着的骨，并且无时无刻不在发生着改建，牙槽骨的改建与牙齿密切相关。在这些改建的过程中，成骨细胞和破骨细胞维持着微妙的平衡。在咀嚼时，咬合力会通过牙齿周韧带传导到牙槽骨上。而牙齿缺失后，该处的牙槽骨由于失去了来自牙周膜的刺激，会发生生理性的骨吸收。临床上，这些吸收最终表现为牙槽嵴高度和宽度的显著减少。研究发现，牙齿缺失后3-12个月间牙槽嵴的宽度可丧失2.6-4.6mm，高度可丧失0.4-3.9mm，从拔牙开始3个月内骨吸收总量可达50％以上，而牙槽骨在唇侧骨板发生的吸收大于舌侧。牙齿缺失后发生的牙槽骨吸收会对口腔颌面部的健康造成危害，若牙槽嵴吸收过多，不仅会影响后期的种植及修复治疗，牙槽骨上附着牙龈的塌陷还会对患者的美观程度造成较大的影响。
目前临床对牙体，牙列缺失修复过程中，主要采用粘膜外活动义齿，并配合牙槽骨内根型种植体，牙槽骨内根型种植体为标椎型采用的是骨内植入，对牙槽骨的高度，宽度，要求过高，因为是柱形，在使用过程中，易造成局部骨吸收，植体脱落。
发明内容
针对现有技术存在的上述问题，本发明的目的是提供一种基于3D打印的牙槽骨内骨外种植修复桥架，以解决上述问题。
为实现上述目的，本发明采用如下技术方案；
本申请提供了一种基于3D打印的牙槽骨内骨外种植修复桥架，其特征在于，所述修复桥架为通过3D打印得到的多孔支架，所述多孔支架具有三维贯通的多孔结构；
所述多孔支架包括支架本体、固位桩、骨钉孔结构以及假牙粘接体，所述支架本体通过所述固位桩和所述骨钉孔结构植入牙槽骨内，以提供支架本体稳定；假牙粘接体设置于所述支架本体表面正向，用于粘接修复假牙。
可选地，所述多孔支架是利用3D建模软件对目标牙槽骨型在CBCT数据指引下进行建模后通过3D打印得到。
可选地，所述多孔支架为高分子材料或金属材料制成。
可选地，所述固定桩为圆柱形支柱或异形支柱。
可选地，所述修复桥架，还包括：将多官能团树脂单体、活性稀释剂、光引发剂、分散剂、光吸收剂和消泡剂按一定配比，中搅拌，并使各组分充分混合均匀，制备得到光敏树脂预混液。
可选地，包括通过高分子粉末激光烧结成型技术以及金属粉末激光烧结成型技术得到所述多孔支架。
本申请提供的一种基于3D打印的牙槽骨内骨外种植修复桥架，复桥架为通过3D打印得到的多孔支架，多孔支架具有三维贯通的多孔结构；多孔支架包括支架本体、固位桩、骨钉孔结构以及假牙粘接体，支架本体通过固位桩和骨钉孔结构植入牙槽骨内，以提供支架本体稳定；假牙粘接体设置于支架本体表面正向，用于粘接修复假牙。可以看出，本申请提供的3D打印牙槽骨外骨内种植修复桥架是根据患者现有牙槽条件，通过3D打印成型，可以提供与牙槽高度匹配的异型植入桥架。
附图说明
图1为本发明实施例提供的牙槽骨内骨外种植修复桥架的示意图；
图2为本发明实施例提供通过牙槽骨内骨外种植修复桥架修复后的牙槽骨示意图。
具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
目前临床对牙体，牙列缺失修复过程中，主要采用粘膜外活动义齿，缺点患者佩戴舒适度较低，咀嚼效率较低，卫生清洁较差，对固位基牙和邻牙有长期的损害。
固定义齿，对基牙永久创伤较大，根型种植牙对牙槽骨基础要求过高，不能满足因牙槽骨量缺失过多的稳定问题。
现有牙槽骨内根型种植体为标椎型采用的是骨内植入，对牙槽骨的高度，宽度，要求过高，因为是柱形，在使用过程中，易造成局部骨吸收，植体脱落。
根据上述目的，本申请实施例提供的一种基于3D打印的牙槽骨内骨外种植修复桥架，修复桥架为通过3D打印得到的多孔支架，多孔支架具有三维贯通的多孔结构，作为假牙与牙槽骨的连接固定装置。
多孔支架包括支架本体、固位桩、骨钉孔结构以及假牙粘接体，支架本体通过固位桩和骨钉孔结构植入牙槽骨内，以提供支架本体稳定；假牙粘接体设置于支架本体表面正向，用于粘接修复假牙。
其中，多孔支架包括支架本体和固定桩，支架本体通过固定桩植入牙槽骨内。固定桩为圆柱形的支柱，还可以为异形支柱。
多孔支架是利用3D建模软件对目标牙槽骨型进行建模后通过3D打印得到，具体在CBCT数据指引下进行建模后通过3D打印得到。多孔支架为高分子材料或金属材料制成。
在本申请实施例中，还包括将多官能团树脂单体、活性稀释剂、光引发剂、分散剂、光吸收剂和消泡剂按一定配比，中速搅拌，使上述各组分充分混合均匀，制备得到光敏树脂预混液，从而制作多孔支架。
在本申请的一个实施例中，基于3D打印的牙槽骨内骨外种植修复桥架的制备的过程还可以通过高分子粉末激光烧结成型技术以及金属粉末激光烧结成型技术得到该修复桥架。
3D打印牙槽骨内骨外种植修复桥架对牙槽基础条件要求采用3维建模，通过3D打印成型，制成牙槽骨外骨内修复桥架，与现有牙槽外形有极高吻合度的异型桥架可增大桥架与牙槽的受力面积，提高桥架的稳定性，减少牙槽骨因局部受力过大而造成对牙槽骨吸收，提高了植体的使用寿命。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
