研究目的: |
观察EVA、PETG-TPU材质以及不同厚度EVA全牙列弹性??垫在牙周基础治疗阶段对Ⅲ期/Ⅳ期牙周炎患者松动后牙的治疗效果,同时评价两种??垫辅助牙周非手术治疗过程中对龈沟液内MMP-8、OPG及RANKL水平的影响,为全牙列弹性??垫应用于Ⅲ期/Ⅳ期牙周炎患者松动后牙提供理论依据。 |

Objectives of Study: |
This study aims to investigate the therapeutic effects of EVA and PETG-TPU materials, as well as EVA elastic occlusal splints of varying thicknesses, on the stabilization of loose posterior teeth in patients with stage III or IV periodontitis during the initial phase of periodontal treatment. Additionally, the study seeks to evaluate the impact of these two types of occlusal splints on the levels of MMP-8, OPG, and RANKL in gingival crevicular fluid during non-surgical periodontal therapy. The findings are intended to provide a theoretical foundation for the application of full dentition elastic occlusal splints in managing loose posterior teeth in patients with advanced periodontitis. |

随机方法(请说明由何人用什么方法产生随机序列): |
由专人对受试者进行随机分组。通过随机数字表为每一位受试者生成相应的随机数,将所得随机数除以组数“4”,按所得余数分别指定为C组、E1组、E2组、PT组:余数为“1”者分入C组,余数为“2”者分入E1组,余数为“3”者分入E2组,整除者分入PT组,并记录在案。在实施过程中不作任何限制、干预或调整。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The subjects were randomly grouped by specially-assigned person. The corresponding random number was generated for each subject through the random number table,and the obtained random number was divided by the group number "4", which was designated as group C, group E1, group E2 and group PT according to the obtained remainder: those with a remainder of "1" were divided into group C, those with a remainder of "2" were divided into group E1, those with a remainder of "3" were divided into group E2, and those with an integral division were divided into group PT, which was recorded. No restrictions, interventions or adjustments are made in the implementation process. |
