【摘要】：目的:通过使用常规咬合纸、数字化咬合仪进行以建立延迟咬合为目的的调牙合,比较两者调牙合的结果及6个月内的变化,为种植体上部咬合设计提供临床参考。方法:对15例种植单冠修复体咬合面使用30μm咬合纸进行以建立延迟咬合为目的的调牙合,运用数字化咬合仪对于另15例种植单冠修复体进行以建立延迟咬合为目的的调牙合。两组调牙合结束后用数字化咬合仪记录并测评其咬合数据。将两组调牙合结束后的咬合数据进行对比,选出两者中建立延迟咬合效果最适宜的调牙合方法;在两组种植修复体完成调牙合后的第1、3、6个月时间节点进行咬合数据的采集、分析,并对于各组种植体进行RVG片拍摄记录,分析种植体近远中骨吸收量,对比两组咬合数据及种植体骨吸收值的差异。使用两种方法对粘接固位的两联冠种植修复体进行调牙合,并在修复体完成调牙合后的第1、3、6个月时间节点,测量分析RVG片中各组种植体近远中骨吸收量的差异。结果:1.使用咬合仪进行建立延迟咬合的调牙合结果优于单纯使用咬合纸组;将使用咬合纸进行以延迟咬合为目的调牙合后的咬合情况与运用数字化咬合仪进行相同目的调牙合后的咬合情况相对比:种植修复体咬合接触面积,占全口牙合力的百分比,与对侧同名天然牙牙合力的比值,以及修复侧牙弓与健侧牙弓牙合力占全口牙合力的比值,均具有统计学意义(P0.05)。2.使用咬合仪建立延迟咬合的种植修复体在调牙合完成后的第1、3个月时间节点时的各项咬合数据,与咬合纸调牙合组存在显著差异(P0.05)。咬合仪调牙合组种植修复体在修复后1、3、6个月咬合力逐渐增加形成渐进性咬合,修复侧与健侧牙弓受力逐步达到平衡。两种方法调牙合后的种植单冠修复体,在修复完成后的第1、3、6个月时间节点拍摄RVG片并测量植体近远中骨吸收量。通过自身对比得出种植体近远中骨吸收量无显著统计学差异(P0.05);对比咬合仪组与常规咬合纸调牙合组在修复后的三个时间节点的种植体近中与远中的骨吸收量,差异均具有统计学意义(P0.05)。3.使用两种方法调牙合后的两联冠种植修复体,在修复完成后的第1、3、6个月时间节点,分别对每一种植体的近远中骨吸收量进行自身对比,差异无统计学意义(P0.05);同组内缺隙侧近中端种植体与缺隙侧远端种植体近远中骨吸收也无显著差异(P0.05);咬合仪组与常规咬合纸调牙合组在修复后第1个月时缺隙侧近中端种植体的近中骨吸收量差异具有统计学意义(P0.05);其他时间节点,两组中各植体近远中骨吸收量差异无明显统计学意义(P0.05)。结论:1.单纯使用咬合纸调牙合的结果受多种主观因素干扰,而数字化咬合仪建立延迟咬合的结果更为客观、准确。2.咬合仪调牙合组的种植修复体在修复后6个月内咬合力逐渐增加,形成渐进性咬合,修复侧与健侧牙弓受力逐步达到平衡。与常规咬合相比,延迟咬合对单冠种植修复体而言具有减小其修复半年内的植体近中与远中骨吸收量的作用。3.对于粘接固位的两联冠种植修复体而言,延迟咬合减少其周围骨吸收量的作用不明显。
[Abstract]:Objective: through the use of conventional bite paper, digital instrument was used to establish the delayed occlusion occlusion for the purpose of occlusal adjustment, compare the results of changes in occlusal adjustment and within 6 months, and provide clinical reference for occlusion of the upper part of the implant design. Methods: 15 cases of implant crown occlusal surfaces using 30 m paper to establish delayed occlusion occlusion for the purpose of occlusal adjustment, the use of digital instrument for the other 15 cases of implant occlusal crown to establish occlusal delay for the purpose of occlusal adjustment. Two groups of occlusal adjustment after the end of the digital recording and evaluating the occlusal occlusal instrument data. Comparing the occlusion data two group occlusal adjustment after the end of two selected establishment delay optimum effect of occlusal occlusal adjustment method; in the two group of implant completed in 1,3,6 months time node occlusal adjustment after the occlusion data collection, analysis, and for each group RVG film record of implant, implant bone analysis near the absorption quantity and value of the differences between two groups of occlusal data and implant bone resorption. Two methods of using retention on the adhesive of two crown implant for occlusal adjustment, and complete the 1,3,6 months time after occlusal adjustment in the restoration, measurement and analysis of differences in the RVG were planted near the far bone absorption. Results: 1. using occlusal instrument setup delay occlusal occlusal adjustment results better than the simple occluding Paper Group; the paper will use the bite to delay for the purpose of regulating the occlusal occlusal tooth and occlusal after using digital instrument for the same purpose of occlusal occlusal adjustment after the contrast: implant occlusal contact area, accounting for full dentition force percentage, and on the side of a natural tooth force ratio, and the repair of dental arch and the contralateral side arch occlusal force for full mouth Occlusal force ratios were statistically significant (P0.05) the occlusion data in 1,3 months time node.2. using occlusal implant was developed and completed in the delayed occlusion adjustment after the tooth, paper and occlusal occlusal adjustment group there were significant differences (P0.05). The occlusal occlusal adjustment group implant instrument in the repair of 1,3,6 months after the bite force increased gradually form progressive occlusion, repair and contralateral side arch stress gradually reached equilibrium. Two methods of occlusal adjustment after the implant crown, 1,3,6 months after the completion of the repair node in the shooting of RVG tablets and measuring implant near the amount of bone resorption. By comparing their implants near bone absorption without statistically significant difference (P0.05); implant contrast group and the conventional instrument occlusal occlusal paper occlusal adjustment group in the three time points after the repair of the proximal and distal bone absorption, the difference is Statistical significance (P0.05.3.) using two methods of occlusal adjustment after two crown implant, 1,3,6 months after the completion of the repair node in the near and far, respectively for each implant bone absorption were compared, the difference was not statistically significant (P0.05); in the same group side gap the proximal end and distal implant gap near implant bone resorption also showed no significant difference (P0.05); bone absorption near the statistical significance of the difference of occlusal instrument group and normal occlusal occlusal adjustment in the repair of paper group at first months after the gap of proximal end of the implant (P0.05); other each time node, planting two group near body bone resorption volume difference was not statistically significant (P0.05). Conclusion: 1. using a simple paper occlusal occlusal adjustment results disturbed by many subjective factors, while the digital instrument setup delay occlusal occlusal result is more objective, accurate.2. occlusal occlusal adjustment instrument Implant in the repair group within 6 months after the bite force increases gradually, the formation of progressive occlusion, repair and contralateral side arch stress gradually reached equilibrium. Compared with conventional occlusion, occlusal restoration of delayed planting single crown has reduced its restoration in the near and far in the absorption amount of.3. for the retention of the two crown implant for planting within half a year, reduce the delay of bone resorption around the occlusal volume had no obvious effect.
