简要总结
The aim of this study is to evaluate of two different construction techniques (digital and conventional techniques) for two implant retained complete mandibular overdenture regarding:
1. Digital occlusion stability detection: evaluated by using OccluSense.
Evaluation was done in the following evaluation period:
T0: Immediately after over denture insertion. T6: 6 months after over denture insertion. T12: 12 months after over denture insertion.
详细描述
Patient selection and study design:
Six patients who required complete denture were selected from the diagnostic clinic of Prosthodontic Department, Faculty of Dentistry, Mansoura University. All patients were informed about the procedures that was done and a written consent form of ethical committee. All patients had the right to withdraw from the study at any time.
Patients Grouping:
Patients were divided in to 2 equal groups:
Group (I): 3 patients received maxillary CD and mandibular 2-implant retained overdenture constructed by digital technique.

结局指标
主要结局
occlusal stability
时间窗: at time of insertion of prosthesis T(0), 6 months after insertion T(6), 12 months after insertion T(12)
Using occlusense device to determine distribution of occlusal forces over anterior and posterior areas, right and left side through chart representing areas of occlusal contact
Occlusal analysis
时间窗: at time of insertion of prosthesis T(0), 6 months after insertion T(6), 12 months after insertion T(12)
Group I and group II will be subjected to test by utilization of the Digital Occlusal Analyzer System (OccluSense) then amount of occlusal force over each unit presented in percentage
