Description

齿槽膜Toothed membrane 技术领域Technical field
本发明涉及一种植牙手术使用的齿槽膜，特别是涉及一种具有良好固定状态的齿槽膜。The present invention relates to a alveolar membrane for use in implant surgery, and more particularly to a cogging membrane having a good fixation state.
背景技术Background technique
一般而言，当牙齿因意外、病变或其他原因脱落后，除美观因素外，尚会影响咀嚼与咬合。因此，牙科医生通常会建议患者进行制作假牙以填补缺漏的牙齿。In general, when the tooth falls off due to accidents, lesions or other reasons, in addition to aesthetic factors, it will affect chewing and bite. Therefore, the dentist usually advises the patient to make a denture to fill the missing tooth.
传统的假牙一般粗分为活动假牙与固定假牙两种。活动假牙，顾名思义，可随时装于口中与从口中拿出，多用于缺损多颗牙齿的患者身上；而固定假牙则是固定于患者的口中，无法任意取下。传统的固定假牙多为桥接式假牙，牙科医师利用两侧牙齿的支撑，做出三颗假牙，而牙桥支撑点在于两侧牙齿。桥接式假牙的缺点是因要套假牙而需要磨损良好的牙齿，才能套入。Traditional dentures are generally divided into active dentures and fixed dentures. Active dentures, as the name implies, can be placed in the mouth and taken out from the mouth at any time, and are often used on patients with multiple teeth; fixed dentures are fixed in the mouth of the patient and cannot be removed at will. Traditional fixed dentures are mostly bridged dentures. The dentist uses the support of the teeth on both sides to make three dentures, while the bridge supports the teeth on both sides. The disadvantage of bridged dentures is that they require a well-weared tooth to fit the denture.
人工植牙是目前愈来愈普遍的治疗牙齿脱落的补牙的方式。人工植牙是一种将人工牙根植入缺牙区的一种治疗方式，其优点在于耐久性高，且无须磨损良好的牙齿。然而，缺牙区的骨组织会随着时间的经过而逐渐萎缩，大约在半年之后，会有大约40％的萎缩状况，造成齿槽骨过薄，而影响植牙的稳定性，甚至导致植牙手术的失败。Artificial dental implants are now the more common way to treat dental fillings. Artificial implants are a treatment for implanting artificial roots into the edentulous area. They have the advantage of high durability and no need to wear well-toothed teeth. However, the bone tissue in the edentulous area will gradually shrink over time. About half a year later, there will be about 40% atrophy, causing the alveolar bone to be too thin, which affects the stability of the implant, and even leads to planting. The failure of dental surgery.
为修复缺牙处的骨头不足的问题，牙科医师通常会先进行补骨手术。所谓的补骨手术是以骨移植物，例如：人造牙或自体骨，填入缺陷的部分，再以齿槽膜包覆该骨移植物，使其维持所需的外型与位置。To repair the problem of insufficient bone at the missing tooth, the dentist usually performs a bone surgery first. The so-called skeletal surgery is to fill the defect with a bone graft, such as an artificial tooth or an autologous bone, and then cover the bone graft with a alveolar membrane to maintain the desired shape and position.
传统的齿槽膜为一具有预定形状的板片，具有一连接部与一覆盖部。该连接部上设有一连接孔，用以与人工牙根结合；该覆盖部上具有多个孔洞，用以包覆骨移植物。有关现有技术的齿槽膜的详细结构，请参照中国台湾发明专利201311218与201332523、美国发明专利2014/0199657与2014/0349251等，在此容不赘述。The conventional alveolar film is a plate having a predetermined shape and has a connecting portion and a covering portion. The connecting portion is provided with a connecting hole for coupling with the artificial root; the covering portion has a plurality of holes for covering the bone graft. For details of the structure of the prior art cogging film, please refer to the Chinese Patent No. 201311218 and 201332523, the US invention patents 2014/0199657 and 2014/0349251, etc., and are not described herein.
由之前所述的结构可知，现有技术的齿槽膜仅一端以连接孔与人工牙根结合，另一端成悬空状，而无任何支撑。不稳定的状态有可能影响到补骨手术的进行，甚至影响植牙手术的成败。 It can be seen from the structure described above that the prior art cogging membrane is joined to the artificial root by only one end of the connecting hole, and the other end is suspended, without any support. Unstable state may affect the progress of bone surgery and even affect the success or failure of implant surgery.
