【摘要】：目的：本实验应用数字咬合力分析仪对牙周炎伴牙合创伤患者和牙周健康者进行动态咬合力分析，通过对比牙合接触时间（occlusion time，，OT），为牙合创伤的诊断提供参考指标；通过对早接触点和牙合干扰点的检测，为牙合创伤的精确调牙合治疗提供新的辅助检查方法，使调牙合更加精准和有效。方法： 1.病例选择与分组收集中重度牙周炎伴牙合创伤患者42例，根据指导调牙合的方法不同随机分成A（分析仪组）、B（咬合纸组）两组；收集20例牙周健康的志愿者作设为C组（对照组），不进行治疗。 2.实验设备和器材（1）艾动咬合力分析仪及TeeTester咬合分析软件v3.1版本（江苏畅微电子科技有限公司）。（2）100微米咬合纸（德国宝诗）。（3）超声波龈上洁治器。（4）龈下刮治器与根面平整器械。（5）williams牙周探针。（6）高速涡轮手机（日本NSK）。 3.实验步骤患者初诊时均记录年龄、性别等一般资料，为每一位入选患者进行全口牙齿检查，记录分析仪组（A组）和咬合纸组（B组）患者的以下牙周检查指标：出血指数（bleeding Index，BI）、探诊深度(probing depth，PD)、附着丧失（attachmentloss、AL）、功能性动度(Functional mobility,FM)，并拍摄全口曲面断层片。测试并对比A、B、C三组的牙合接触时间（occlusion time，OT）。对A、B两组进行牙周局部治疗（包括龈上洁治和龈下刮治），六周后检查治疗效果并进行统计分析。之后进行调牙合治疗，在指导调牙合时A组使用咬合纸配合咬合力分析仪检查咬合，B组仅使用咬合纸检查咬合，治疗后四周对比A、B两组的治疗效果，测试并对比A、B、C三组的OT值。 4.数据处理使用SPSS13.0软件包对数据进行统计分析，计量资料以x±s表示。A、B、C三组的年龄、性别、OT值的组间比较采用方差分析，A、B两组的AL、PD、BI、FM的组间比较和治疗前后自身比较均采用配对t检验。结果： 1.牙周治疗前，测试仪组（A）、咬合纸组（B）、对照组（C）的性别、年龄组间比较均无显著差异(P0.05)；A、B两组的AL、PD、BI、FM组间均无显著差异(P0.05)；A组与B组OT无显著差异(P0.05)，均大于C组，差异有统计学意义(P0.05)。 2.牙周局部治疗六周后，A组与B组的OT值与治疗前自身相比下降，两组治疗后均大于C组，差异有统计学意义(P0.05)； A、B两组的PD、BI、FM治疗后与治疗前自身相比均下降，差异有统计学意义(P0.05)，两组间比较无显著差异(P0.05)。 3.调牙合治疗四周后，A、B两组的PD、BI、OT、FM与调牙合治疗前相比均下降，差异有统计学意(P0.05)；PD、FM、OT值组间比较结果A组均小于B组，差异有统计学意义(P0.05)； A组与C组的OT值无显著差异(P0.05)，B组OT值高于C组，差异有统计学意义(P0.05)。结论： 1.咬合力定量分析对中重度牙周炎的牙合创伤具有临床诊断意义。 2.应用咬合力分析仪检查能够为中重度牙周炎伴牙合创伤患者的临床诊断提供量化参考指标，提高调牙合治疗效果。
[Abstract]:Objective: The dynamic occlusal force of periodontitis patients with occlusal trauma and periodontal health was analyzed by digital bite force analyzer, and the occlusal force was analyzed by comparing the occlusal contact time and occlusion time to provide a reference index for the diagnosis of occlusal trauma. Through the detection of early contact points and occlusal interference points, a new auxiliary examination method is provided for the treatment of occlusal trauma, which makes the occlusal adjustment more accurate and effective. Methods: 1. Case selection and grouping Forty-two patients with moderate and severe periodontitis with occlusion trauma were randomly divided into two groups: group A (Analyzer Group) and Group B (Occlusal Paper Group), and 20 healthy volunteers were selected as group C (control group, not treated). 2. Experimental equipment and equipment TeeTester bite Analysis Software v3.1 version (Jiangsu Chang Microelectronics Technology Co., Ltd. A 100-micron bite paper (German Baoshi). Ultrasonic upper gingival cleaning apparatus. Subgingival curettes and root leveling instruments. Williams periodontal probe. High Speed Turbo phone (NSKN, Japan). 3. Experimental steps At the first visit, the patients recorded the general data of age, sex, and so on, and carried out a full-mouth dental examination for each of the selected patients. The following indexes of periodontal examination were recorded: bleeding index (bleeds index), probing depth (PD), attachment loss loss (ALL), functional mobility (FM), and total surface tomography (TOC). The occlusal contact time and occlusion time were measured and compared among the three groups. The local periodontal therapy (including supragingival scaling and subgingival curettage) was performed in group A and B, and the therapeutic effect was examined and statistically analyzed six weeks later. The occlusal paper combined with occlusal force analyzer was used in group A to check the occlusal force in group A, and only the bite paper was used in group B. The therapeutic effects of group A and group B were compared four weeks after treatment, and the OT values of group C were tested and compared. 4. Data processing The data were statistically analyzed by SPSS13.0 software package. The age and sex of the three groups were expressed in terms of x 卤s. The comparison of the values of gender and OT was compared by ANOVA. The comparison between the two groups and the comparison before and after treatment were conducted by paired t test. Results: 1. Before periodontal treatment, there was no significant difference in sex and age between the two groups. There was no significant difference between the two groups. There was no significant difference between group A and group B (P 0.05), and there was no significant difference between group A (P 0.05) and group B (P 0.05), and there was no significant difference between group A (P 0.05) and group B (P 0.05), and there was no significant difference between group B (P 0.05) and group B (P 0.05), and there was no significant difference between group A (P 0.05) and group B (P 0.05). 2. After 6 weeks of local periodontal treatment, the OT values of group A and group B were lower than those of group C after treatment, and the difference was statistically significant (P 0.05), and that of group A B was lower than that of group A (P 0.05), and that of group A (group B) was lower than that of group B (P < 0.05), and that of group A (group B) was lower than that of group C (P < 0.05). The difference was statistically significant (P 0.05), but there was no significant difference between the two groups (P 0.05). 3. After four weeks of occlusal adjustment treatment, the PDBII OTT FM of group A was lower than that of group B, and the difference was statistically significant. The results of comparison between group A and group B were lower than that of group B. There was no significant difference in OT value between group A and group C. The OT value of group B was higher than that of group C, and the difference was statistically significant (P 0.05). Conclusion: 1. Quantitative analysis of occlusal force is of clinical significance in the diagnosis of occlusion trauma in moderate and severe periodontitis. 2. The use of occlusal force analyzer can provide a quantitative reference index for the clinical diagnosis of moderate and severe periodontitis with occlusal trauma and improve the effect of occlusal adjustment.
