Description

牙列缺失数字化口腔种植定位器二次拟合制造方法 Edentulous digital dental cultivation method for producing a quadratic fit locator

技术领域 FIELD

[0001] 本发明属于种植义齿修复技术领域,特别涉及一种牙列缺失数字化口腔种植定位器二次拟合制造方法。 [0001] The present invention belongs to the technical field of implant dentures, denture particularly, to a digital dental retainer cultivation method for producing a quadratic fit.

背景技术 Background technique

[0002] 口腔种植修复己经成为临床应用日益增多的实用技术,随着市场的不断扩大以及当前时期患者对美学要求的不断提高,口腔种植修复技术的核心己经由着重于种植体的牢固性和材料的生物相容性逐渐转向了更高精度和自然美观。 [0002] Oral Implantology restoration has become an increasing number of practical clinical application of technology, with the continuous improvement of the aesthetic requirements of the market continues to expand the current period as well as patients, oral implant rehabilitation technology has been a core focus on the implant via solid and biocompatible material gradually shifted higher precision and natural beauty.

[0003] 传统的口腔种植修复技术,是由医生根据经验,通过二维断层图像推断患者的三维骨结构和软组织状况,以此来制定手术计划和实施手术,风险大、精度差。 [0003] traditional dental implant restoration techniques by a physician based on experience, concluded that the three-dimensional structure of bone and soft tissue condition of the patient through a two-dimensional tomographic images, in order to develop surgical planning and implementation of surgery, the risk of large, poor accuracy. 2011年,申请人针对该技术问题深度开展技术研发并获得重大突破,申请了以“口腔种植定位器制作方法” (专利号:2〇1110261622.6)为核心的多项专利,并获得授权。 In 2011, the depth of the problem for the applicant to carry out R & D and technology major breakthrough, in order to apply for the "Oral Implantology locator production methods" (patent number: 2〇1110261622.6) as the core of a number of patents, and authorized. 基于上述技术的系列产品也迅速占领国内市场,得到了市场和行业的广泛认可。 Series of products based on the technology quickly occupied the domestic market, it has been widely recognized by the market and the industry.

[0004] 在实际的应用中,临床医生普遍反映:该制作方法多适用于一般的牙位缺失情况, 对于要求较高的无牙颂种植不能十分精确的按客户期望的位置设计种植牙位位点,而且在修复时也可能存在难以修复的问题。 [0004] In practical applications, clinicians generally reflect: the production methods and more applicable to the general lack of teeth in the case, for demanding toothless song planting can not be very precise desired location according to customer design implant bit point, and there may also be difficult to repair in repair.

[0005] 主要原因在于:该制作方法,虽然已经实现了让医生在计算机软件的辅助作用下在三维立体模型上设计种植点位和手术方案,但医生更多的是保证种植体在上下颌颌骨内取得最稳定高效的固位,也就是设计出了完美的种植窝。 [0005] The main reason is: the production method, although the doctor has achieved the planting design point and surgical options on three-dimensional models in the computer software supporting role, but more doctors is to ensure that the upper and lower jaw implant obtain the most stable and efficient retention of the bone, which is to design a perfect osteotomy. 但在实际应用中,由于患者本身牙列缺失,即上颂或下颌甚至双侧,完全没有牙体存在,导致在拟合时,石膏牙三维扫描数据并不能十分准确的和口腔内部环境的三维立体模型准确拟合,微小的偏差都会导致种植修复效果不理想。 However, in practical applications, since the edentulous patients themselves, i.e., the maxillary or mandibular even bilateral, no tooth is present, when fitting the leads, and not very accurate three-dimensional and environmental intraoral dental gypsum 3D scan data accurate three-dimensional model fitting, small deviations will result in implant restoration is not ideal.

[0006]由此导致经常需要对连接牙冠和种植体的基台进行调整甚至改造。 [0006] thereby resulting in the need for frequent connection implant and abutment crown adjustment even transformation. 但这依然不足以解决牙冠排列不整齐以及咬颌不准确的问题,反而会影响到整体结构的稳定合理以及美观。 But this is still not enough to solve crown irregular arrangement and jaw bite is not accurate, it will affect the stability of the overall structure is reasonable and beautiful.

具体实施方式 Detailed ways

[0027]为能进一步了解本发明的内容、特点及功效,兹例举以下实施例详细说明如下: [0028]当患者存在牙列缺失时,可采用本方法来制作口腔种植定位器。 Detailed Description [0027] The further understanding of the present invention, the characteristics and effects, hereby exemplified by the following examples as follows: [0028] When present edentulous patient, the method employed to prepare oral implantology locator.

[0029]首先让患者制取石膏牙模型,依据咬合关系在石膏牙模型上排制蜡牙,在蜡牙上放置两处以上的阻射物作为放射参考点,形成放射义齿。 [0029] First patient preparation plaster teeth model, based on the occlusal tooth plaster model is made of wax tooth row, placing two or more radiopacity was dental wax as a reference point radiation, the radiation forming the denture. 阻射物可以是但不限于锆珠、硫酸钡等。 Radiopacity may be, but is not limited to zirconium beads, barium sulfate and the like. 之所以需要放置两处及以上的阻射物,是因为单一点位的重合无法保证准确重合。 The need for the placement of two or more thereof radiopacity, because single point can not be guaranteed accurate position coinciding overlap. [0030]患者佩戴放射义齿拍摄口腔CT,将患者口腔CT数据导入植牙与定位器定制系统中,根据患者具体情况对计算机软件设置的各项阈值进行调节(相应的计算机软件为公知技术)。 [0030] The patient wears radiation denture shooting oral CT, the mouth of a patient CT data lead implant locator customization system, conditioned (corresponding computer software known techniques) to the threshold computer software configured in accordance with specific circumstances of patients. 将患者口腔构建出三维模型,真实完整地显示出三维骨结构和软组织状况,在该三维视图上,通过旋转、缩放、透明化等功能,观察各不同截面,得到任意局部的三维骨结构和软组织以及神经分布状况,建立全方位种植修复手术模拟环境。 The patient's mouth constructed three-dimensional model, the real complete display of three-dimensional bone structure and soft tissue condition, on the three-dimensional view, by rotation, scaling, transparency and other functions, to observe the different sections to give a three-dimensional bone structure of any local soft tissue and nerve distribution, the establishment of comprehensive implant restoration surgery simulation environment.

[°031]将带有放射义齿的石膏牙模型进行三维数字扫描,根据放射参考点,将患者口腔内部环境的三维立体模型,与带有放射义齿的石膏牙三维扫描数据进行一次拟合。 [° 031] The tooth plaster model with the three-dimensional digital dental radiological scanning, according to the reference point of the radiation, the three-dimensional model of the environment inside the patient's mouth, once fitted with the three-dimensional scanning data with dental plaster radiation denture. 依据一次拟合的结果,选取合适品牌、型号的种植体,确定种植位点,设计种植修复方案。 Based on the results of a fit, select the appropriate brand and model of the implant to determine planting sites, planting design rehabilitation program.

[0032]在一次拟合中,患者佩戴了放射义齿,石膏牙也带有放射义齿,而后使二者的放射参考点的位置重合,即是正确的拟合位置。 [0032] In a fitting, the patient wears the denture radiation, but also with the radiation denture tooth plaster, then the position of the reference point of the radiation both coincide, i.e., the correct fitting position. 之所以这样做,是因为患者本身牙列缺失,如果单纯做CT,在石膏模型也牙列缺失的情况下,完全没有一颗牙可以作为二者位置重合的标志,则无法将二者精确对位。 The reason to do this because edentulous patients themselves, if you simply do CT, in the case of plaster models are also edentulous, no sign can be used as both a tooth overlap position, it can not be precise on both bit.

[0033]将一次拟合得到的整体模型,与去除放射义齿的石膏牙三维扫描数据,进行二次拟合,依据二次拟合的结果设计出口腔种植定位器模型。 [0033] The entire fitting a model obtained, the plaster dental 3D scan data denture removal radiation, secondary fitting outlet chamber resulting design model based on the positioning planting quadratic fit. 根据生成的口腔种植定位器模型, 获得口腔种植定位器的加工文件,将口腔种植定位器加工文件传送3D打印机,加工出口腔种植定位器。 The oral planting locator model generation, oral implantology is obtained processing file locator, the locator oral implantology file transfer processing 3D printer cultivation process outlet chamber positioner.

[0034] 也就是说,旧有技术的出发点,还是让种植体去适应领骨,而本申请则来源于市场需求,由修复后的牙冠和患者的颌骨共同决定种植体的型号和定位。 [0034] In other words, the starting point of the old technology, or allow the implant to adapt collar bone, and this application is derived from the market demand, jointly decided by the type and location of the implant and the patient's jaw bone crown after repair . 于是,依据一次拟合的结果,选取合适品牌、型号的种植体,确定种植位点,设计种植修复方案。 Thus, according to the results of a fit, select the appropriate brand and model of the implant to determine planting sites, planting design rehabilitation program.

[0035]将去除放射义齿的石膏牙模型进行三维数字扫描,将该扫描数据与一次拟合结果的三维模型进行二次拟合。 [0035] The tooth plaster model is removed three-dimensional digital dental radiology scans, the scan data to perform a three-dimensional model fitting results of a quadratic fit. 这里的二次拟合,其作用基本相当于旧有技术中的拟合。 Here quadratic fit, its role is equivalent to the old basic fitting techniques. 这样就生成了口腔种植定位器模型,并进一步获得了口腔种植定位器的加工文件,将口腔种植定位器加工文件传送至3D打印机,加工出口腔种植定位器。 This creates a model oral implant positioning, and further to obtain the oral implant processing file locator, the locator oral implantology transfer file to the 3D printer processing, the export processing chamber planting locator.

[0036] 这样制作出的口腔种植定位器,其材质和外观与旧有技术制作出的产品,表面并无差异,但其精度更高,临床实验中,种植体的最终位置和设计位置的偏离可被控制在〇_〇lmm 之内。 [0036] The thus produced oral implant locator materials and appearance of the old technology to produce a product, no difference in the surface, but higher accuracy, clinical trials, departing from the design position and the final position of the implant It can be controlled within the 〇_〇lmm.
