本研究的目的是评估植入骨性固定义齿后咀嚼节律模式可能发生的适应性变化。记录修复前、修复后2个月和10年的咀嚼周期持续时间、下颌运动速度和移位情况。多年来，在周期持续时间方面，除了咬合水平阶段减少外，没有发生重大变化。然而，在康复2个月后，记录到明显更高的下颌速度和更大的移位。从长远来看，这一趋势进一步确立。有节奏咀嚼的时间计时似乎相对一致，这表明驱动输出的中央模式生成器随着时间的推移是恒定的。
The aim of this study was to assess possible adaptive changes in the masticatory rhythmical pattern after insertion of an osseointegrated fixed denture. Registrations of masticatory cycle duration, mandibular velocity, and displacement were performed before and 2 months and 10 years after rehabilitation. No major changes except for a decreased occlusal level phase had occurred regarding cycle duration over the years. However, a significantly higher mandibular velocity and greater displacement were recorded 2 months after rehabilitation. This trend was further established in the long term. Temporal timing of rhythmical chewing seems to be relatively consistent, suggesting that the central pattern generator driving output over time is constant.
