Abstract
Description
Translated fromChinese技术领域technical field
本发明涉及医疗用品技术领域，具体涉及一种适用于窄牙槽嵴的新型口腔种植体及植入装置。The invention relates to the technical field of medical supplies, in particular to a novel oral implant suitable for narrow alveolar ridges and an implant device.
背景技术Background technique
种植牙，即以植入到缺牙区牙槽骨内的人工牙根作为基桩，完成上部牙冠的恢复，其形态及结构与自然牙非常接近，具有功能好、美观、舒适等优点。Dental implant is to use the artificial tooth root implanted in the alveolar bone of the edentulous area as the foundation post to complete the restoration of the upper crown. Its shape and structure are very close to natural teeth, and it has the advantages of good function, beauty and comfort.
目前，种植牙逐渐成为修复牙列缺损与缺失的优选方案；然而，临床上许多拟进行种植牙治疗患者的牙槽骨宽度变窄，给种植牙治疗带来诸多困难。牙槽骨宽度变窄主要由下述三个原因造成：一是牙齿缺失前便存在牙周疾病、牙周疾病导致牙槽骨吸收变窄；二是患者没能及时进行种植牙治疗、缺牙时间较长，牙齿缺失后牙槽骨持续吸收、其宽度随着时间的推延而变得越来越窄；三是患者缺牙后选择活动义齿修复、义齿基托长期压迫缺牙区牙槽嵴而加重骨吸收，导致牙槽嵴变窄。At present, dental implants have gradually become the preferred solution for repairing dentition defects and loss; however, in clinical practice, the alveolar bone width of many patients who intend to undergo dental implant treatment has narrowed, which brings many difficulties to dental implant treatment. The narrowing of alveolar bone width is mainly caused by the following three reasons: first, periodontal disease exists before tooth loss, and periodontal disease leads to narrowing of alveolar bone resorption; After a long time, the alveolar bone continues to resorb after tooth loss, and its width becomes narrower and narrower with time; third, the patient chooses a removable denture for repair after tooth loss, and the denture base presses the alveolar ridge in the edentulous area for a long time And aggravate bone resorption, resulting in narrowing of the alveolar ridge.
牙种植体行使其功能的前提是其植入到颌骨内并与骨组织发生骨结合；为保证种植体能顺利实现骨结合与长期稳定性，种植体植入后在其颊舌侧至少需要有厚度为1.0 mm的骨组织；因此，窄牙槽嵴患者的种植牙治疗属于复杂治疗、面临较大挑战；当牙槽嵴宽度不大于6.0mm时、常出现常规直径种植体（即直径为3.5～4.5mm的种植体）无法植入的问题。The prerequisite for dental implants to perform their functions is that they are implanted into the jawbone and osseointegrated with bone tissue. The bone tissue with a thickness of 1.0 mm; therefore, the implant treatment of patients with narrow alveolar ridges is a complex treatment and faces great challenges; when the width of the alveolar ridge is not greater than 6.0 mm, implants with conventional diameters (that is, with a diameter of 3.5 ~4.5mm implants) cannot be implanted.
目前，解决窄牙槽嵴种植的方法主要包括：植骨种植技术和选用小直径种植体。植骨种植技术，即在常规直径种植体植入后在其骨缺损的部位植入骨替代材料，其极大的扩展了种植的适应证；然而，植骨种植技术往往需要取自体骨、存在两个术区（即取骨区和植骨区），导致手术创伤大，对于老年患者、患有严重基础疾病的患者而言伤害大、无法进行种植。小直径种植体（即直径为3.0～3.5mm的种植体）的强度远低于常规径种植体，易发生力学并发症（如折断、松动等），因此小直径种植体仅适用于上颌侧切牙和下颌切牙位置的种植、适用范围窄。At present, the methods to solve narrow alveolar ridge implants mainly include: bone graft implant technology and selection of small diameter implants. Bone graft implantation technology, that is, to implant bone substitute materials in the bone defect after implantation of conventional diameter implants, which greatly expands the indications of implantation; however, bone graft implantation technology often requires autogenous bone, existing Two operation areas (namely, bone extraction area and bone grafting area) lead to large surgical trauma, and for elderly patients and patients with serious underlying diseases, the damage is large and implantation cannot be performed. Small-diameter implants (i.e. implants with a diameter of 3.0-3.5mm) are much weaker than regular-diameter implants, and are prone to mechanical complications (such as fracture, loosening, etc.), so small-diameter implants are only suitable for maxillary lateral incisors And the implantation of mandibular incisor position, the scope of application is narrow.
综上所述，目前针对窄牙槽嵴种植的两种主要方法均存在不可避免的缺陷：即植骨种植技术手术创伤大、无法完全适用于老年患者与患有严重基础疾病的患者，小直径种植体力学强度低、适用范围窄、无法普遍适用窄牙槽嵴病例。To sum up, the two main methods for narrow alveolar ridge implantation have inevitable defects: the bone graft implantation technique has a large surgical trauma, cannot be fully applied to elderly patients and patients with serious underlying diseases, and the small diameter The mechanical strength of the implant is low, the scope of application is narrow, and it cannot be generally applied to cases with narrow alveolar ridges.

再之后，采用骨钻穿过种植导板50的金属导环52内壁、并对待种植区域进行钻孔；钻孔过程中骨钻被金属导环内壁限位，金属导环52截面为类矩形、其尺寸大于骨钻的刃部，即骨钻的刃部在金属导环52的限制范围内进行骨组织的切割，最终形成截面为类矩形的种植窝洞。需要说明的是：传统进行种植窝洞预备时，一般先采用直径小的骨钻（例如2.0mm），再选用直径逐级增大骨钻（2.5、3.0、3.5、4.0mm）；而本实施例中，首先采用直径3.0mm骨钻在导环的限制下进行骨切割，再选用2.0、1.0mm的骨钻沿着导环的内壁进行种植窝边缘的细修，确保种植窝的形态与种植体本体10结构一致；After that, a bone drill is used to pass through the inner wall of the
最后，在种植窝预备到达预定的深度和大小后，采用按压或者敲击的方式植入种植体本体10。Finally, after the implant socket is prepared to reach a predetermined depth and size, the
在植入于牙槽骨内的种植体本体10与骨组织实现骨结合后，进行基台20的连接，将固位螺丝30穿过基台20并就位，采用扭矩扳手给固位螺丝30施加30～35Ncm扭矩、将其拧紧，制作适合患者口内咬合情况的种植牙冠40，并将种植牙冠40粘结至基台20上。临床佩戴后，种植牙冠40的边缘线一般位于牙龈缘下方0.5～1.0mm，种植牙冠40合面留有孔道，其与固位螺丝30通道相通，树脂材料封闭此孔道，需要时可去除树脂露出固位螺丝30通道，螺丝刀伸入其中可旋松固位螺丝30，对种植修复体进行维护。After the
对于本领域的技术人员来说，在不脱离本发明结构的前提下，还可以作出若干变形和改进。例如：针对窄牙槽嵴的全口或半口无牙颌患者，对本发明中基台上部的形态和结构进行调整，使其成为locator、杆卡式、球帽式种植覆盖义齿；再例如：对种植体本体10外表面棱嵴结构13的横截面形态调整为类矩形或类梯形，以期达到本发明之效果，上述这些也应该视为本发明的保护范围，这些都不会影响本发明实施的效果和专利的范围。For those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. For example: for patients with full or partially edentulous jaws with narrow alveolar ridges, the shape and structure of the upper part of the abutment in the present invention are adjusted to make it a locator, bar type, and ball cap type implant overdenture; another example: The cross-sectional shape of the
在本发明中，除非另有明确的规定和限定，术语“安装”、“设置”、“连接”、“固定”、“旋接”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是半机械连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定，对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。In the present invention, terms such as "installation", "installation", "connection", "fixation" and "rotation connection" should be interpreted in a broad sense unless otherwise clearly specified and limited, for example, it may be a fixed connection, or It can be a detachable connection or integrated; it can be a mechanical connection or a semi-mechanical connection; it can be a direct connection or an indirect connection through an intermediary; it can be the internal communication of two components or the interaction of two components Unless otherwise clearly defined, those skilled in the art can understand the specific meanings of the above terms in the present invention according to specific situations.
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
