Description
技术领域 technical field
本发明属于临床口腔医学技术领域，尤其是涉及一种植入人体颌骨中的牙种植体。The invention belongs to the technical field of clinical stomatology, and in particular relates to a dental implant implanted in human jaw.
背景技术 Background technique
牙缺失是人类常见病和多发病，据统计，现在全世界65亿人口中有近20亿人患各种牙病，而我国失牙、缺牙和各类牙病患者就超过3.7亿人。2007年卫生部进行的第三次全国口腔健康流行病学调查结果显示，我国50岁以上人群平均失牙数为11颗，65岁以上人群全部牙齿缺失高达30%。作为牙缺失修复的革命性进步，牙种植技术彻底改变了传统口腔修复的理念和模式，在临床上取得良好的治疗效果。与传统的镶牙方法（义齿修复）相比种植牙手术价格较贵（是传统镶牙的2.5倍），但牙种植体可终身使用，且美观舒适，而义齿需要维护和重做。2010年仅中国就有20万人采用了这种先进的治疗方法，而韩国和巴西均已达到100万人，近几年该数量还将以30%～40%的速度增长。目前国内临床应用的种植体绝大部分由国外进口，多以西方人种的颌骨结构特征为基础研发，不能适应我国患者的牙颌结构，影响了最终修复效果。Tooth loss is a common and frequently-occurring disease in humans. According to statistics, nearly 2 billion of the 6.5 billion people in the world suffer from various dental diseases, while in my country there are more than 370 million patients with tooth loss, tooth loss and various dental diseases. According to the third national oral health epidemiological survey conducted by the Ministry of Health in 2007, the average number of teeth lost by people over the age of 50 in my country is 11, and the total number of teeth lost by people over the age of 65 is as high as 30%. As a revolutionary advancement in the restoration of missing teeth, dental implant technology has completely changed the concept and model of traditional oral restoration, and has achieved good clinical results. Compared with the traditional denture method (denture restoration), the price of dental implant surgery is more expensive (2.5 times that of traditional dentures), but dental implants can be used for life, and are beautiful and comfortable, while dentures need maintenance and redo. In 2010, 200,000 people in China alone adopted this advanced treatment method, while South Korea and Brazil both reached 1 million people, and the number will increase at a rate of 30% to 40% in recent years. At present, most of the implants used in clinical practice in China are imported from abroad, and most of them are developed on the basis of the jaw structure characteristics of Western races, which cannot adapt to the jaw structure of Chinese patients and affect the final restoration effect.
牙种植体按照外形可分为有圆柱状牙种植体、螺纹状牙种植体和复合异型牙种植体等，所有牙种植体的设计思路和技术指标主要是临床手术操作方便、接合好、术后稳定、生物相容性好、骨细胞生长快等。为了提高种植体与颌骨的结合能力和种植体的稳定性，学者在种植体的表面形貌和表面涂层做了很多的研究，通过改变种植体表面形貌，提高界面稳定性、骨结合率，但是通过种植体表面处理涂层的处理对生物相容性和生长速率有显著的影响，对骨接合和术后稳定性等作用确实不多。为此，改进和设计出手术操作方便，接合好、术后稳定性好的牙种植体是非常重要。Dental implants can be divided into cylindrical dental implants, threaded dental implants and composite special-shaped dental implants according to their appearance. Stable, good biocompatibility, fast growth of bone cells, etc. In order to improve the bonding ability between the implant and the jawbone and the stability of the implant, scholars have done a lot of research on the surface morphology and surface coating of the implant. By changing the surface morphology of the implant, the interface stability and osseointegration can be improved. However, the treatment of implant surface treatment coating has a significant impact on biocompatibility and growth rate, and does not have much effect on osseointegration and postoperative stability. For this reason, it is very important to improve and design a dental implant that is easy to operate, well-engaged, and postoperatively stable.

本发明与现有技术相比具有以下优点：Compared with the prior art, the present invention has the following advantages:
1、结构简单、设计合理且临床操作简便。1. Simple structure, reasonable design and convenient clinical operation.
2、本发明在牙种基体的外表面开有便于其旋入人体颌骨的螺旋刃槽，螺旋刃槽可以在手术安装过程中随着牙种基体旋转，螺旋刃槽会由下至上逐渐受力产生连续切削作用，便于牙种基体旋入；因螺旋刃槽的数量至少为两道，使得牙种基体在旋转安装时受力均匀，即对牙种基体的安装起导正作用。因此，螺旋刃槽的设置不仅能够强有效完成牙种植体的安装，并能保证牙种基体植入人体颌骨后长期稳定不易松动，且接合好，术后恢复好。2. The present invention has a spiral edge groove on the outer surface of the dental seed base to facilitate its screwing into the human jaw. The spiral edge groove can rotate with the dental seed base during the operation installation process, and the spiral edge groove will be gradually affected from bottom to top. The force produces a continuous cutting effect, which is convenient for the dental seed base to be screwed in; because the number of helical blade grooves is at least two, the force on the dental seed base is even when it is rotated and installed, that is, it plays a guiding role in the installation of the dental seed base. Therefore, the setting of the helical groove can not only effectively complete the installation of the dental implant, but also ensure the long-term stability of the dental implant matrix after it is implanted in the human jawbone, and the joint is good, and the postoperative recovery is good.
3、由于牙种植体安装到位在人体颌骨后，生活中会存在牙齿咬合、摩擦等作用力可能会使牙种植体产生松动，而本发明牙种植体通过在牙种基体的外表面开有螺旋刃槽，所以安装时在扭力扳手的作用下，螺旋刃槽右侧的自攻螺纹对人体颌骨会产生切削作用，这样人体颌骨的骨组织和部分软组织会残留在螺旋刃槽中，此时螺旋刃槽左侧的自攻螺纹横切面在反作用力下，可以有效阻止牙种植体安装后牙齿咬合力、摩擦力等作用力使牙种植体不易出现松动或脱落。3. After the dental implant is installed in place on the human jaw, there will be forces such as tooth occlusion and friction in life, which may cause the dental implant to loosen. However, the dental implant of the present invention has a Helical edge groove, so under the action of the torque wrench during installation, the self-tapping thread on the right side of the helical edge groove will have a cutting effect on the human jaw, so that the bone tissue and part of the soft tissue of the human jaw will remain in the helical edge groove. At this time, the self-tapping thread cross-section on the left side of the helical blade groove is under the reaction force, which can effectively prevent the tooth occlusal force, friction force and other forces after the dental implant is installed, so that the dental implant is not easy to loosen or fall off.
4、本发明是针对我国人种的颌骨结构特征设计的，因此可有效适用于我国人们牙齿缺损、不全、校正等的替换或修复。4. The present invention is designed for the jawbone structure characteristics of the Chinese race, so it can be effectively applied to the replacement or repair of tooth defects, incompleteness, correction, etc. of Chinese people.

具体实施方式 Detailed ways
如图1和图4所示，本发明包括外周具有自攻螺纹1的牙种基体2和设置在牙种基体2上端且与牙种基体2相连接的牙种基台4，所述牙种基体2的外表面开有便于其旋入人体颌骨的螺旋刃槽3，所述螺旋刃槽3的数量至少为两道。当牙种植体旋入人体颌骨时，螺旋刃槽3上的左圆弧起阻力作用，右圆弧起切削刃口作用，因此使得牙种植体容易旋入人体颌骨，不易出现松动、脱落现象。As shown in Fig. 1 and Fig. 4, the present invention includes a dental seed matrix 2 with a self-tapping thread 1 on the periphery and a dental seed abutment 4 that is arranged on the upper end of the dental seed matrix 2 and connected with the dental seed matrix 2. The outer surface of the base body 2 is provided with helical blade grooves 3 for screwing into the human jawbone, and the number of the helical blade grooves 3 is at least two. When the dental implant is screwed into the human jaw, the left circular arc on the helical groove 3 acts as a resistance, and the right circular arc acts as a cutting edge, so that the dental implant is easy to screw into the human jaw, and is not easy to loosen and fall off Phenomenon.
如图2和图4所示，本实施例中，所述螺旋刃槽3的横截面形状为圆弧状，所述螺旋刃槽3的横截面半径R为0.4mm～0.8mm。因螺旋刃槽3的形状为圆弧状，所以在安装时，在作用力下螺旋刃槽3右侧的自攻螺纹横切面相当于切削刃口，咬合力、摩擦力较小，而螺旋刃槽3右侧的自攻螺纹横切面在骨组织、软组织等的阻力下起作用，阻碍牙种植体松动；安装到位后，生活中会存在牙齿咬合、摩擦等作用力可能会使牙种植体松动，人体颌骨的骨组织和部分软组织会残留在螺旋刃槽3中，此时螺旋刃槽左侧的自攻螺纹横切面在反作用力下，可以有效阻止牙种植体安装后牙齿咬合力、摩擦力等作用力使牙种植体不易出现松动或脱落。As shown in FIG. 2 and FIG. 4 , in this embodiment, the cross-sectional shape of the helical blade groove 3 is arc-shaped, and the cross-sectional radius R of the helical blade groove 3 is 0.4mm˜0.8mm. Because the shape of the helical edge groove 3 is arc-shaped, during installation, the self-tapping thread cross-section on the right side of the helical edge groove 3 is equivalent to the cutting edge under the applied force, and the bite force and friction force are small, while the helical edge The self-tapping thread cross-section on the right side of groove 3 works under the resistance of bone tissue and soft tissue, etc., and hinders the loosening of the dental implant; after it is installed in place, there will be forces such as tooth occlusal and friction in life that may cause the dental implant to loosen , the bone tissue and part of the soft tissue of the human jaw will remain in the helical groove 3. At this time, the self-tapping thread cross-section on the left side of the helical groove is under the reaction force, which can effectively prevent the teeth from occlusal force and friction after the dental implant is installed. Force and other forces make the dental implant less likely to loosen or fall off.
如图1所示，本实施例中，所述螺旋刃槽3在水平面上的投影长度L为4mm～10mm，螺旋刃槽3可以在手术安装过程中随着牙种基体2旋转，螺旋刃槽3由下至上呈螺旋状会逐渐受力产生连续切削作用，便于牙种基体旋入。As shown in Figure 1, in this embodiment, the projected length L of the spiral edge groove 3 on the horizontal plane is 4 mm to 10 mm, and the spiral edge groove 3 can rotate with the tooth seed matrix 2 during the surgical installation process, and the spiral edge groove 3 3. The spiral form from bottom to top will be gradually stressed to produce continuous cutting effect, which is convenient for screwing in the dental seed matrix.

During actual production, it is produced according to the classification of human teeth.
如图3所示，本实施例中，所述自攻螺纹1为三角形螺纹或梯形螺纹，所述自攻螺纹1的牙型角α的度数为5°～25°，所述自攻螺纹1的工作高度h为0.2mm～0.6mm，所述自攻螺纹1的螺纹升角为15°～75°。实际制作时，随着牙种植体的安装部位和直径不同，可将这些参数做相应的调整。As shown in Figure 3, in this embodiment, the self-tapping thread 1 is a triangular thread or a trapezoidal thread, and the degree of the profile angle α of the self-tapping thread 1 is 5° to 25°, and the self-tapping thread 1 The working height h of the self-tapping thread 1 is 0.2mm-0.6mm, and the lead angle of the self-tapping thread 1 is 15°-75°. During actual production, these parameters can be adjusted accordingly as the installation site and diameter of the dental implant are different.
本实施例中，根据牙种植体的安装位置和直径不同，螺旋刃槽3的横截面半径R不同，当所述自攻螺纹1的牙形高度H大于0.5mm，所述螺旋刃槽3的横截面半径R（螺旋刃槽的槽深）大于自攻螺纹1的牙形高度H为0.1mm～0.2mm；当所述自攻螺纹1的牙形高度H不大于0.5mm，所述螺旋刃槽3的横截面半径R（螺旋刃槽的槽深）等于自攻螺纹1的牙形高度H。In this embodiment, according to the installation position and diameter of the dental implant, the cross-sectional radius R of the helical edge groove 3 is different. When the profile height H of the self-tapping thread 1 is greater than 0.5mm, the helical edge groove 3 The radius R of the cross section (groove depth of the helical edge groove) is 0.1 mm to 0.2 mm greater than the profile height H of the self-tapping thread 1; when the profile height H of the self-tapping thread 1 is not greater than 0.5 mm, the spiral edge The cross-sectional radius R of the groove 3 (the groove depth of the helical edge groove) is equal to the profile height H of the self-tapping thread 1 .
本实施例中，所述牙种基体2的长度为6mm～12.2mm，所述牙种基体2和牙种基台4的总长度为8mm～14mm。In this embodiment, the length of the dental seed base 2 is 6 mm to 12.2 mm, and the total length of the dental seed base 2 and the dental seed abutment 4 is 8 mm to 14 mm.
如图1和图4所示，本实施例中，所述牙种基台4为空心正六棱柱体，所述牙种基体2的上部中心设置有便于与烤瓷牙连接的紧固螺纹5，所述牙种基台4和牙种基体2一体成型。牙种基台4采用空心正六棱柱体，便于将牙种基台4安装在人体颌骨上。As shown in Fig. 1 and Fig. 4, in this embodiment, the tooth seed abutment 4 is a hollow regular hexagonal prism, and the upper center of the tooth seed base 2 is provided with a fastening thread 5 which is convenient for connecting with a porcelain tooth. The dental seed abutment 4 and the dental seed base 2 are integrally formed. The dental seed abutment 4 adopts a hollow regular hexagonal prism, which is convenient for the dental seed abutment 4 to be installed on the human jaw.
安装时，通过扭力扳手旋转牙种基台4，则牙种基台4带动牙种基体2进入人体颌骨的骨孔（骨孔直径为Ф3.3mm）中，在牙种基体2旋入时自攻螺纹1在扭力扳手的作用下，与骨孔周围骨组织产生挤压作用，与此同时螺旋刃槽3右侧的自攻螺纹产生切削作用便于牙种基体2旋入；牙种植体安装到位后，由于螺旋刃槽3右侧自攻螺纹的切削作用会有少量骨组织以及生理盐水等存留在螺旋刃槽3中，在牙种植体愈合期间由于咬压力、摩擦力等作用，螺旋刃槽3左侧的自攻螺纹在骨组织、软组织及涂层的作用力下形成重要的阻力面，使牙种植体不易松动、脱落。因此，本发明的牙种植体具有结构简单，设计合理，操作方便，安装稳定的特点。During installation, rotate the dental seed base 4 with a torque wrench, and the dental seed base 4 drives the dental seed base 2 into the bone hole of the human jaw (the diameter of the bone hole is Ф3.3mm). When the dental seed base 2 is screwed in Under the action of the torque wrench, the self-tapping thread 1 will squeeze the bone tissue around the bone hole, and at the same time, the self-tapping thread on the right side of the helical blade groove 3 will produce a cutting effect to facilitate the screwing of the dental implant base 2; dental implant installation After it is in place, due to the cutting effect of the self-tapping thread on the right side of the helical blade groove 3, a small amount of bone tissue and saline will remain in the helical blade groove 3.
