【摘要】：目的:通過使用常規(guī)咬合紙、數(shù)字化咬合儀進行以建立延遲咬合為目的的調牙合,比較兩者調牙合的結果及6個月內的變化,為種植體上部咬合設計提供臨床參考。方法:對15例種植單冠修復體咬合面使用30μm咬合紙進行以建立延遲咬合為目的的調牙合,運用數(shù)字化咬合儀對于另15例種植單冠修復體進行以建立延遲咬合為目的的調牙合。兩組調牙合結束后用數(shù)字化咬合儀記錄并測評其咬合數(shù)據(jù)。將兩組調牙合結束后的咬合數(shù)據(jù)進行對比,選出兩者中建立延遲咬合效果最適宜的調牙合方法;在兩組種植修復體完成調牙合后的第1、3、6個月時間節(jié)點進行咬合數(shù)據(jù)的采集、分析,并對于各組種植體進行RVG片拍攝記錄,分析種植體近遠中骨吸收量,對比兩組咬合數(shù)據(jù)及種植體骨吸收值的差異。使用兩種方法對粘接固位的兩聯(lián)冠種植修復體進行調牙合,并在修復體完成調牙合后的第1、3、6個月時間節(jié)點,測量分析RVG片中各組種植體近遠中骨吸收量的差異。結果:1.使用咬合儀進行建立延遲咬合的調牙合結果優(yōu)于單純使用咬合紙組;將使用咬合紙進行以延遲咬合為目的調牙合后的咬合情況與運用數(shù)字化咬合儀進行相同目的調牙合后的咬合情況相對比:種植修復體咬合接觸面積,占全口牙合力的百分比,與對側同名天然牙牙合力的比值,以及修復側牙弓與健側牙弓牙合力占全口牙合力的比值,均具有統(tǒng)計學意義(P0.05)。2.使用咬合儀建立延遲咬合的種植修復體在調牙合完成后的第1、3個月時間節(jié)點時的各項咬合數(shù)據(jù),與咬合紙調牙合組存在顯著差異(P0.05)。咬合儀調牙合組種植修復體在修復后1、3、6個月咬合力逐漸增加形成漸進性咬合,修復側與健側牙弓受力逐步達到平衡。兩種方法調牙合后的種植單冠修復體,在修復完成后的第1、3、6個月時間節(jié)點拍攝RVG片并測量植體近遠中骨吸收量。通過自身對比得出種植體近遠中骨吸收量無顯著統(tǒng)計學差異(P0.05);對比咬合儀組與常規(guī)咬合紙調牙合組在修復后的三個時間節(jié)點的種植體近中與遠中的骨吸收量,差異均具有統(tǒng)計學意義(P0.05)。3.使用兩種方法調牙合后的兩聯(lián)冠種植修復體,在修復完成后的第1、3、6個月時間節(jié)點,分別對每一種植體的近遠中骨吸收量進行自身對比,差異無統(tǒng)計學意義(P0.05);同組內缺隙側近中端種植體與缺隙側遠端種植體近遠中骨吸收也無顯著差異(P0.05);咬合儀組與常規(guī)咬合紙調牙合組在修復后第1個月時缺隙側近中端種植體的近中骨吸收量差異具有統(tǒng)計學意義(P0.05);其他時間節(jié)點,兩組中各植體近遠中骨吸收量差異無明顯統(tǒng)計學意義(P0.05)。結論:1.單純使用咬合紙調牙合的結果受多種主觀因素干擾,而數(shù)字化咬合儀建立延遲咬合的結果更為客觀、準確。2.咬合儀調牙合組的種植修復體在修復后6個月內咬合力逐漸增加,形成漸進性咬合,修復側與健側牙弓受力逐步達到平衡。與常規(guī)咬合相比,延遲咬合對單冠種植修復體而言具有減小其修復半年內的植體近中與遠中骨吸收量的作用。3.對于粘接固位的兩聯(lián)冠種植修復體而言,延遲咬合減少其周圍骨吸收量的作用不明顯。
[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.
