摘要

简介口腔环境是一个具有不同 pH 值的复杂电解质环境,其中金属修复体会释放金属离子。这些离子可通过内在和外在途径诱导细胞凋亡。牙科合金需要具有出色的耐磨性和生物相容性,这样才能延长活动义齿的使用寿命。研究目的研究由钴铬合金 Remanium GM 700 和镍铬合金 Remanium CSe 制成的固定铸造义齿存在时和多次重熔后口腔液中的微量元素组成和 pH 值。材料和方法。120 名 25 至 60 岁的患者参加了我们的研究,其中包括 79 名女性(65.9%)和 41 名男性(34.1%),他们被分为 4 组,每组 30 人。本研究对钴铬合金和镍铬合金制成的 Remanium GM 700 和 Remanium CSe 固定铸造义齿存在时和多次重熔后口腔液中的微量元素组成和 pH 值进行了研究。根据牙列缺损的类型和地形,为患者制作永久性铸造义齿。结果7 天后,使用指定合金制作固态铸造义齿的患者的 pH 值偏向酸性,3 个月后达到中性值。pH 值变化的动态和表现程度取决于研究的时间、合金的质量以及义齿固铸结构的制造工艺。结论。我们确定,在固态铸造义齿存在的情况下,口腔液中微元素的组成会在随机因素的影响下发生变化。所研究的合金不会对患者的机体造成伤害,因此可用于生产固态铸造义齿结构。

CHANGES IN THE MICROELEMENT COMPOSITION AND PH OF THE ORAL LIQUID AFTER PROSTHESIS WITH SOLID-CAST BRIDGE DENTURES
Introduction. The environment of the oral cavity is a complex electrolyte environment with variable pH values, in which metal restorations release metal ions. These ions can induce cell apoptosis through intrinsic and extrinsic pathways. Dental alloys require excellent wear resistance and biocompatibility, which can extend the service life of removable prostheses. Aim. To study the composition of microelements and pH in the oral fluid in the presence of fixed cast prostheses made of cobalt-chromium and nickel-chromium alloys Remanium GM 700 and Remanium CSe of certified delivery and after multiple remelting. Materials and methods. 120 patients aged 25 to 60 took part in our study, including 79 women (65.9%) and 41 men (34.1%), who were divided into 4 groups of 30 people each. In the presented research studied the composition of microelements and pH in the oral fluid in the presence of fixed cast prostheses made of cobalt-chromium and nickel-chromium alloys Remanium GM 700 and Remanium CSe of certified supply and after multiple remelting. Depending on the type and topography of the defect in the dental row, patients were made permanent cast dentures. Results. After 7 days, the pH value shifted to the acidic side in people who were made solid-cast constructions with the specified alloys, and after 3 months it reached a neutral value. The dynamics and degree of expression of the change in pH depend on the timing of the study, the quality of the alloy, and the technological process of manufacturing solid-cast structures of dental prostheses. Conclusions. We determined that the composition of microelements of oral fluid in the presence of solid-cast prostheses changes under the influence of random factors. The studied alloys do not harm the patient's organism and therefore can be used for the production of solid-cast constructions of dental prostheses.
