帮您找到了一篇“口腔不良修复体的危害及防治”：

摘要目的：通过对156例口腔不良修复体治疗，说明不良修复体的危害。方法：用快慢速涡沦机、去冠钳、持针器，祛除156例固定、活动不良修复体。结果：巧6例固定活动不良修复体均会导致口腔各种并发症。结论：不良修复体不符合口腔生理解剖特点，给牙周、牙体造成不良影响。

关键词：不良修复体并发症防治

一、临床资料

收治口腔不良修复体患者巧156例，男81例，女75例（为活动、固定义齿修复），年龄40一76岁123例，18一40岁33例（为桩冠或固定义齿修复）。

类型分析：①结扎类49例，此类较常见，用0.2的结扎丝“8”字形结扎于缺隙两侧基牙的颈部，缺牙间隙用自凝塑料填塞，塑料进人两基牙的邻缺隙倒凹区固位。②卡环类41例，用约0.smm的钢丝弯制的卡环作为固位体，用自凝塑料填塞于缺牙间隙内，有一定的动度，但不能自行摘戴。③锤造类34例。用锤造式的金属粘贴于牙齿的愕或舌侧，使上领或下领牙齿成为整体，使口腔内少量牙齿暂时不会脱落，但粘结材料填塞了所有牙齿的间隙，使牙齿间存在大量食物碎川乡戴环类：22例，用软金属片环抱于牙体以修复邻近的缺失牙。⑤桩冠类10例。

并发症：①牙眼出血：由于修复体形成悬突并且无自洁作用，不能自行取戴清洁，义齿覆盖区食物存积经常刺激软组织而致牙跟发炎出血。②基牙松动、龋坏：由于不考虑牙周的生理代偿能力，不论缺隙大小均用缺隙的近远中2颗牙做基牙，加之食物残渣不能清洁，菌斑、牙石沉积从而造成基牙松动、龋坏。③口腔异味：由于食物残渣滞留及低廉材料的原因，从而引起口臭。④恶变：不良修复体制作粗造，加之长期的慢性炎性刺激可使口腔勃膜癌变。

治疗：对于不良修复体只有立刻拆除。对固定钢丝+自凝塑胶牙做成的不良修复体的拆除，应先将基牙牙颈部表面的钢丝用高速涡轮机磨断，祛除倒凹部分的充填物，再用持针钳或去冠钳轻轻取下不良修复体（注意保护软组织）。对无缝冠锤造固定桥不良修复体的拆除方法：用高速涡轮机将无缝冠的轴面（颊面）磨穿，将无缝冠桥分成几个小的单位的固位体，再用破冠钳将它们一一钳除。拆除时，保护松动的基牙，以免随之脱落。随访观察3个月，各种并发症基本消失，此时可考虑重新进行符合生理解剖要求的义齿修复。

二、讨论

口腔修复是建立在口腔解剖生理、材料生物力学原理及医学美学等基础之上的综合性的学科。一个良好的修复体不但要恢复外观、咀嚼功能，还要对口腔组织有生理保健作用。

Its unique advantages of oral implants (invasive, good shape, fixed durable, etc.), repair fractures in the implant and fixed prosthesis, temporomandibular joint reconstruction has played a pivotal role. The key lies in the healing after planting. Current and implant-related research areas focus on the biological mechanics, molecular biology, cell biology and other areas to speed up the cultivation of the healing interface. 1 implant healing Bone - implant interface, there will be two more after the results: with fibrous or bony integration. The former is inserted between the implant and bone health, dense collagen tissue, and periodontal ligament different, they are non-functional, the event of a fiber binding, as evidenced by the failure of implant surgery. Branemark 60s in the last century the concept of osseointegration was first proposed, that does not exist between implant and bone tissue binding than is the latter. This is a growing industry breakthrough and become the medical profession recognized the growing medical solid theoretical foundation and planting guidelines for a successful operation. Implant healing and fracture healing tissue similar process, but the bone - implant and bone healing - the healing of bone are not identical between, the mechanism has not yet fully understood. Implant healing process is divided into [1]： ① wound healing and woven bone formation phase, is an important part of early healing of implant； ② lamellar bone and the conversion of densification； ③ maturation and adaptation period. The whole process takes roughly a year's time. 2 to accelerate bone - implant interface healing status of correlation 2.1 The mechanical and chemical surface treatment methods used to implant or coating surface roughness, so that it has better biocompatibility, surface roughening methods often include sandblasting method, etching method, plasma spraying , laser treatment method, etc., access to micro-roughening the surface of the interface from the cellular level to promote healing. Nasatzky [2] studies have shown that micro-rough surface can be attached to osteoblasts, enhancing its sensitivity, thereby promoting the value and differentiation, and synthesis of some growth factors to accelerate bone healing, increase bone - implant interface binding, other Implants can also enhance the stress resistance. In vitro results showed that micro-blasting the surface morphology after the etching is more benefit from the growth of osteoblast differentiation, osteocalcin secretion. However, there is still a lack of crude long-term clinical trial of implant assessment. Accelerate the cultivation of surface coating technology is also an important means of healing the interface, which includes titanium plasma coating and hydroxyapatite coating. The former is at a high temperature, the droplets of molten titanium and high-speed jet attached to the implant surface, forming loose rough surface, also known as plasma spraying of titanium (titanium plasma sprayed, TPS) coating. Electron microscope, the coating pores were round or irregular, and communicate with each other. Animal studies show that, after coating titanium plasma treatment, the porous implant surface structure will not only increase the surface area, and in three-dimensional space with each other. Histological bone implant to loosen the TPS internal growth, the equivalent effect of a mechanical latches [4]. The latter of hydroxyapatite (hydroxyapatite, HA), the body main inorganic component of bone tissue, has good biological activity, tissue compatibility and biological stability. HA coating of high purity stable crystals of hydroxyapatite bone implants maintained between the mechanical and chemical combination. Histological observation showed that the main reason for accelerating the healing of cultivation is its interface can promote bone tissue deposited on the surface. Early in the healing of two implants have a positive effect [4]; HA coated titanium surface is higher than bone TPS coated titanium [5,6], and this prevents bone HA is absorbed [6]. It should be emphasized that the growing success of the operation depends on the coating adhesion to the extracellular matrix directly. Some scholars have observed that, pollution will reduce the coating titanium surface and extracellular matrix adhesion [7,8]. Darimont et al [6] observed that the fracture line coated implant interface. This shows that the implant surface treatment technology is the key to success.。
