Abstract

一种牙咬控机头导板及制作方法，该导板包括受上牙、上牙槽骨或黏膜控制的上基体(1)和受下牙、下牙槽骨或黏膜控制的下基体(2)，上基体(1)和下基体(2)之间设有支撑体(3)，在该支撑体(3)、上基体(1)或下基体(2)上设有对种植机头进行定位导向的控制机构。使用时，将导板放置在患者上下牙齿之间，通过上下牙齿分别与上基体和下基体进行咬合固定。再将机头放置在根据种植数据设置的控制机构内，种植打孔时使机头沿控制机构方向移动至牙槽骨。由于该导板对机头进行导向定位，提高定位导向精度，避免导板直接与高速转动的钻头接触，不会额外增加钻头的发热量。所述导板只需要由患者咬合即可固定，因而种植牙作业时无需多人操作，降低种植牙操作的难度。

[0039] 具体地说， 所述种植手机采用现有技术， 包括两种， 一是带手柄的种植手机， 手柄与种植机头连接， 用于控制种植手机移动； 另一种不带手柄的种植手机， 通过外部机械臂等控制种植机头移动， 两种种植手机都可适用。 本实施例采用 第一种种植手机进一步说明， 即包括种植机头 C2、 手机手柄 C1和种植钻头 C3， 该种植钻头 C3由种植机头 C2。
[0040] 所述上基体 1和下基体 2与上牙 A和下牙 B、 上牙槽骨与下牙槽骨或口腔上下黏 膜控制， 也可以是它们之间组合控制。
[0041] 所述控制机构包括设于支撑体 3的固定槽 31， 该固定槽 31设置的角度根据种植 窝的位置、 种植牙的角度、 深度等种植数据来制作， 该固定槽 31通常由一个圆 形通孔和设置在该圆形通孔侧壁的幵口槽 32组成， 该幵口槽 32大小不限定， 优 选采用能保证导向套筒 4固定， 即幵口槽 32的宽度小于圆形通孔的直径， 保证导 向套筒 4只能从固定槽 31两端进入并与固定槽 31固定。 所述固定槽 31的结构不作 特别限定， 既可以采用截面为圆形、 弧形， 也可以是正多边形等。
[0042] 所述固定槽 31内设有导向套筒 4， 即导向套筒 4固定在固定槽 31内， 该导向套筒 4内设有沿其长度方向滑动的固定筒 5， 该固定筒 5与种植机头 C2固定， 使种植机 头 C2能与其同步沿导向套筒 4上下滑动， 所述固定筒 5与导向套筒 4滑动吋不发生 除沿导向套筒 4长度方向以外方向发生移动。 在导向套筒 4侧面设有供种植手机 手柄 C1移动的导向套筒幵口 41。 所述导向套筒幵口 41小于导向套筒 4的内直径， 避导向套筒 4沿导向套筒 4移动吋脱离导向套筒 4， 影响种植孔的精度。 采用固定 筒 5与导向套筒 4配合， 可以适配不同的种植机头 C2形状,提高产品适用性。
[0043] 所述导向套筒 4与固定筒 5之间采用间隙配合， 使固定筒 5既可以沿导向套筒 4滑 动， 又可以使固定筒 5径向上与导向套筒 4较小的间隙， 使其不会对种植打孔的 精度产生影响； 当直接通过匹配的种植机头 C2与导向套筒 4配合滑动吋， 种植机 头 C2与导向套筒 4之间也应当满足固定筒 5与导向套筒 4之间配合要求。
[0044] 如果所述种植机头 C2采用与导向套筒 4匹配结构， 如种植机头 C2外形规则， 如 圆柱状吋， 种植机头 C2沿导向套筒 4滑动吋不发生偏移， 就可以满足种植打孔精 度要求， 此种情况下可以不需要固定筒 5， 直接由种植机头 C2与导向套筒 4配合 滑动， 此吋的导向套筒幵口 41应当于小种植机头 C直径， 避免种植机头 C2沿导向 套筒 4移动吋脱离导向套筒 4， 影响种植打孔的精度。
[0045] 使用吋， 将导板放置在患者上下牙齿之间， 通过由患者上下牙齿分别与上基体 和下基体进行咬合固定， 该导板设有根据种植数据设置的控制机构。 再将机头 放置在与之匹配的控制机构内， 种植打孔吋机头沿控制机构方向移动至牙槽骨 。 由于导板对机头进行导向定位， 避免导板直接与高速转动的钻头接触， 减少 磨损导致打孔精度偏差， 提高定位精度， 又减少损耗， 也不会额外增加钻头的 发热量。 所述导板只需要由患者咬合即可固定， 因而种植牙作业吋无需多人操 作， 降低种植牙操作的难度。
[0046] 根据需要， 所述控制机构可以设置在上基体、 下基体或支撑体上， 能实现对种 植机头进行定位导向即可， 上述实施例仅以控制机构支撑体为例说明， 并不构 成将控制机构设置在上基体或下基体的限制。
[0047] 本实施例中， 为了保证种植牙的精度， 需要导板固定吋有较好的稳定性和可靠 性， 可以在上基体 1和下基体 2上设有与牙齿、 牙槽骨或黏膜形状相同的定位槽 1 1， 该定位槽 11与对应的牙齿、 牙槽骨或黏膜完全一致， 这样通过咬合吋， 可以 避免发生位移， 从而保证种植打孔位置的精度。 根据需要， 也可以只在与种植 打孔一侧的上基体 1或下基体 2上设有与牙齿、 牙槽骨或黏膜形状相同的定位槽 1 1， 但其固定的稳定性和精度与上下基体都设有定位槽 11吋的精度和稳定性好。
[0048] 所述固定槽 31的截面形状不作特别限定， 可以是圆形， 也可以是多边形， 无论 何种形状， 其应当与导向套筒 4匹配， 保证能固定导向套筒 4不发生移动。 所述 导向套筒 4的材质不作特别限定， 根据需要可以采用金属材质， 如不锈钢。 所述 固定筒 5的材质不作特别限定， 根据需要也可以采用金属材质， 如不锈钢。
[0049] 为了保证精确控制种植孔的深度， 在所述固定槽 41内设有限制固定筒或种植机 头 C2移动的限位结构 （附图未标示） 。
[0050] 为了更好降低手机钻头 C3热量， 避免出现手机钻头过热导致烧骨， 靠近种植 打孔一端的固定槽 31或 /和导向套筒 4端部沿其径向设有冷却槽 （附图未标） ， 使 冷却液直接进入冷却创口， 避免种植钻头 C3温度过高而导致烧骨， 使手术失败 。 同吋在打孔过程中便于观察导板的就位情况及手术创口的情况。
[0051] 由于多个机械结构之间的配合， 精度比较困难， 可以在所述导向套筒 4与种植 机头 C2或固定筒 5之间设有使它们之间接触面小， 更容易高精度加工的导向结构 ， 如导向条等， 可以提高种植精度。
[0052] 如图 6所示， 本发明还提供一种上述实施例牙咬控机头导板的制作方法， 该牙 咬控机头导板的制作方法包括：
[0053] 步骤 S10， 建立口腔三维模型， 采集口腔数据， 根据采集的口腔数据建立口腔 三维模型；
[0054] 步骤 Sl l， 确定种植体数据， 根据口腔三维模型确定单颗或多颗种植体的种植 数据；
[0055] 步骤 S12， 制作种植牙导板， 根据确定的确定种植体数据制作与口腔三维模型 匹配受上牙或者上牙槽骨控制的上基体和受下牙或者下牙槽骨控制的下基体， 以及设置连接上基体和下基体的支撑体， 该支撑体、 上基体或下基体上设有对 种植机头进行定位导向的控制机构。
[0056] 具体地说， 先获取种植牙患者口腔数据， 采用现有技术获得口腔数据， 如牙齿 、 牙槽骨等数据， 通过现有的数字技术建立口腔三维模型， 设计单颗或多颗种 植体， 输出种植数据。
[0057] 再将口腔三维模型数据和种植数据导入切削设备或 3D打印机内制作种植牙导板 ， 该导板包括受上牙或者上牙槽骨控制的上基体和受下牙或者下牙槽骨控制的 下基体， 以及设置连接上基体和下基体的支撑体， 该支撑体上设置与单颗或多 颗种植体数据对应的控制机构， 其中该控制机构对种植机头进行定位导向。
[0058] 所述牙咬控机头导板的具体结构和使用过程及达到的技术效果与上述实施例相 同或相近， 不再赘述。
[0059] 以上实施例仅用以说明本发明的技术方案， 而非对其限制； 尽管参照前述实施 例对本发明进行了详细的说明， 本领域的普通技术人员应当理解： 其依然可以 对前述各实施例所记载的技术方案进行修改， 或者对其中部分技术特征进行等 同替换， 而这些修改或替换， 并还使相应技术方案的本质脱离本发明各实施例 技术方案的精神和范围。
