During complete denture fabrication making Interocclusal records plays an integral role to obtain the condylar guidance value. The study was conducted to compare the protrusive condylar guidance registration by two interocclusal recording materials-Quick setting plaster and Luxabite®(bisacrylic composite) in semi adjustable articulator for completely edentulous patients.
Maxillary and Mandibular casts of the completely edentulous patients were mounted in Hanau®Wide Vue articulator. The Quick setting plaster and Luxabite®(bisacrylic composite) was used as interocclusal recording materials to program the protrusive condylar guidance angles in the articulators.
The protrusive condylar guidance values registered in the articulator for the different interocclusal records were tabulated and statistically analyzed.. The mean protrusive condylar guidance values registered in the articulator was compared with two parameters obtained from the radiographic tracings -- the protrusive condylar path angle obtained with Quick setting plaster and Luxabite with the inclination of articular eminence to the Frankfort horizontal plane.
From the study it was concluded that the Luxabite®(bisacrylic composite) material demonstrated better reproducibility of protrusive condylar guidance registration.than the Quick setting plaster.
在全口义齿制作过程中，制作颌位记录对于获得髁导关系值起着至关重要的作用。本研究旨在比较两种颌位记录材料——快凝石膏和 Luxabite®（双丙烯酸酯复合材料）在半可调式颌架上对无牙颌患者进行前伸髁导关系记录的效果。
将无牙颌患者的上颌和下颌模型安装在 Hanau®宽视野颌架上。使用快凝石膏和 Luxabite®（双丙烯酸酯复合材料）作为颌位记录材料，在颌架上记录前伸髁导关系角度。
记录了不同颌位记录的颌架上前伸髁导关系值，并进行了统计学分析。比较了两种从放射影像轨迹获得的参数——使用快凝石膏和 Luxabite 记录的前伸髁道角与关节突的倾斜度相对于法兰克福平面的倾斜度。
从研究中得出结论，与快凝石膏相比，Luxabite®（双丙烯酸酯复合材料）在前伸髁导关系记录的重现性方面表现更好。
