Description

种植体中央螺栓断裂取出工具及取出方法 Fracture central screw implant and extraction tool extraction method

技术领域 FIELD

[0001] 本发明涉及牙科种植领域,特别涉及一种种植体中央螺栓断裂取出工具及取出方法。 [0001] The present invention relates to the field of dental implant, more particularly to a central screw implant extraction tool breakage and unloading method.

背景技术 Background technique

[0002] 牙科种植技术经过长时间的发展,越来越广泛地被认可。 [0002] dental implant technology is a long development, more and more widely recognized. 然而因为种种原因,例如不正确的用牙习惯,频繁咀嚼硬物或种植体材料长期处于疲劳状态会导致种植体系统的断裂。 However, for various reasons, such as incorrect habits with the teeth, implants frequently chew hard material or a long period can cause fatigue fracture of the implant system. 调查统计,种植体系统在口腔中的破裂80%是中央螺栓的断裂。 Survey, ruptured implant system in the oral cavity of the central screw 80% breakage. 研宄表明,排除材料内部缺陷的因素影响,断裂的原因主要是在螺栓的螺纹顶面处造成的应力集中,应力过大。 A Subsidiary that excluding internal factors defective materials because of fracture is mainly caused at the top surface of the threaded bolt stress concentration, too much stress.

[0003] 由于螺栓尺寸过小,断裂面与种植体内螺纹齐平,常规方法很难取出。 [0003] Since the bolt size is too small, the fracture surface is flush with the threaded vivo cultivation, conventional methods are difficult to remove. 现在常见的方法是将种植体整体取出,然后再种植,这不仅对患者造成很大损伤和痛苦,而且需要重新等待几个月的时间以使种植体与牙槽骨整合。 Now common method is to remove the implant as a whole, and then planting, which not only caused great damage and suffering to the patient, but also need to wait for several months to allow the implant and alveolar bone integration.

[0004] 这时如果有一种工具和方法在不移动种植体的情况下能够方便的取出断裂的中央螺检,就可以最大程度的减少病人的痛苦和损失,避免人力、物力、财力及时间的损失,减少医患纠纷,也有利于种植牙技术的开展。 [0004] In this case, if there is a tool and method can be easily moved without the removal of broken spiro subject the central implant cases, can reduce pain and loss of maximum patient, avoiding manpower, material and financial resources and time losses, reduce medical disputes, but also conducive to dental implant technology.
