Thirteen patients with complete dentures in the maxilla were treated with implants to support a removable bar-retained overdenture for 1 year. Thereafter, the patients were provided with fixed prostheses and were followed up for another year. Maximal occlusal force and mandibular movements were recorded with and without the bar supporting the denture and then during the subsequent year with fixed prostheses. Significant changes in occlusal force capacity and mandibular movements were observed when the bar was removed. Less obvious functional changes were found when the fixed prostheses were placed, with the exception of occlusal force levels, which increased significantly over time.
对上颌全口义齿的13名患者进行种植治疗，以支持可摘式杆卡固位覆盖义齿1年。此后，为患者安装固定修复体，并随访1年。在有和没有杆支撑义齿的情况下记录最大咬合力和下颌运动，然后在随后的一年中使用固定修复体进行记录。当移除杆时，观察到咬合力和下颌运动有显著变化。当安装固定修复体时，除咬合力水平随时间显著增加外，发现功能变化不太明显。
