目的：通过随机交叉对照试验，比较单种植覆盖义齿（IODs）和临床可接受的全口义齿（CD）的混合能力（MA）、粉碎能力（CA）和最大咬合力（MBF）。在每例患者的联合区域中间插入一个植入物。将患者随机分为两组：IC组接受IOD，而CI组接受CD，为期2个月;在接下来的2个月内互换治疗。结果：IODs组的MA、CA、MBF均显著高于旧CD组和新CD组（P <0.01），IODs组的MA、CA、MBF均显著高于新CD组（P< 0.01）。结论：与CD相比，IOD能更有效地恢复无牙颌下颌骨的MA、CA和MBF。
Purpose: The study aimed to compare the mixing ability (MA), comminuting ability (CA), and maximum bite force (MBF) of single-implant overdentures (IODs) and clinically acceptable complete dentures (CDs) through a randomized crossover control trial.Methods: New CDs were fabricated for 22 patients. One implant was inserted in the middle of the symphyseal region for each patient. The patients were randomly allocated into two groups: group IC received an IOD, whereas group CI received a CD, for 2 months; the treatments were interchanged for the next 2 months. The MA, CA, and MBF were evaluated with the old CDs, new CDs (at the end of CD treatment period), and IODs (at the end of IOD treatment period).Results: The MA, CA, and MBF of the IODs were significantly higher than those of the old and new CDs (p< 0.01). New CDs only showed a significant improvement in MA (p< 0.05), while there were no significant differences in CA and MBF between the old and new CDs.Conclusions: Compared with the CD, IOD is more effective in restoring the MA, CA, and MBF of edentulous mandibles.
