【摘要】：目的： 本實驗應(yīng)用數(shù)字咬合力分析儀對牙周炎伴牙合創(chuàng)傷患者和牙周健康者進行動態(tài)咬合力分析，通過對比牙合接觸時間（occlusion time，，OT），為牙合創(chuàng)傷的診斷提供參考指標(biāo)；通過對早接觸點和牙合干擾點的檢測，為牙合創(chuàng)傷的精確調(diào)牙合治療提供新的輔助檢查方法，使調(diào)牙合更加精準(zhǔn)和有效。 方法： 1.病例選擇與分組 收集中重度牙周炎伴牙合創(chuàng)傷患者42例，根據(jù)指導(dǎo)調(diào)牙合的方法不同隨機分成A（分析儀組）、B（咬合紙組）兩組；收集20例牙周健康的志愿者作設(shè)為C組（對照組），不進行治療。 2.實驗設(shè)備和器材 （1）艾動咬合力分析儀及TeeTester咬合分析軟件v3.1版本（江蘇暢微電子科技有限公司）。 （2）100微米咬合紙（德國寶詩）。 （3）超聲波齦上潔治器。 （4）齦下刮治器與根面平整器械。 （5）williams牙周探針。 （6）高速渦輪手機（日本NSK）。 3.實驗步驟 患者初診時均記錄年齡、性別等一般資料，為每一位入選患者進行全口牙齒檢查，記錄分析儀組（A組）和咬合紙組（B組）患者的以下牙周檢查指標(biāo)：出血指數(shù)（bleeding Index，BI）、探診深度(probing depth，PD)、附著喪失（attachmentloss、AL）、功能性動度(Functional mobility,FM)，并拍攝全口曲面斷層片。 測試并對比A、B、C三組的牙合接觸時間（occlusion time，OT）。 對A、B兩組進行牙周局部治療（包括齦上潔治和齦下刮治），六周后檢查治療效果并進行統(tǒng)計分析。之后進行調(diào)牙合治療，在指導(dǎo)調(diào)牙合時A組使用咬合紙配合咬合力分析儀檢查咬合，B組僅使用咬合紙檢查咬合，治療后四周對比A、B兩組的治療效果，測試并對比A、B、C三組的OT值。 4.數(shù)據(jù)處理 使用SPSS13.0軟件包對數(shù)據(jù)進行統(tǒng)計分析，計量資料以x±s表示。A、B、C三組的年齡、性別、OT值的組間比較采用方差分析，A、B兩組的AL、PD、BI、FM的組間比較和治療前后自身比較均采用配對t檢驗。 結(jié)果： 1.牙周治療前，測試儀組（A）、咬合紙組（B）、對照組（C）的性別、年齡組間比較均無顯著差異(P0.05)；A、B兩組的AL、PD、BI、FM組間均無顯著差異(P0.05)；A組與B組OT無顯著差異(P0.05)，均大于C組，差異有統(tǒng)計學(xué)意義(P0.05)。 2.牙周局部治療六周后，A組與B組的OT值與治療前自身相比下降，兩組治療后均大于C組，差異有統(tǒng)計學(xué)意義(P0.05)； A、B兩組的PD、BI、FM治療后與治療前自身相比均下降，差異有統(tǒng)計學(xué)意義(P0.05)，兩組間比較無顯著差異(P0.05)。 3.調(diào)牙合治療四周后，A、B兩組的PD、BI、OT、FM與調(diào)牙合治療前相比均下降，差異有統(tǒng)計學(xué)意(P0.05)；PD、FM、OT值組間比較結(jié)果A組均小于B組，差異有統(tǒng)計學(xué)意義(P0.05)； A組與C組的OT值無顯著差異(P0.05)，B組OT值高于C組，差異有統(tǒng)計學(xué)意義(P0.05)。 結(jié)論： 1.咬合力定量分析對中重度牙周炎的牙合創(chuàng)傷具有臨床診斷意義。 2.應(yīng)用咬合力分析儀檢查能夠為中重度牙周炎伴牙合創(chuàng)傷患者的臨床診斷提供量化參考指標(biāo)，提高調(diào)牙合治療效果。
[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 鹵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.
