In model Im456 (Fig. 8d), under loads 100 and 200 N, the occlusal force at the premolars on the defect side was larger than that in model Im4567 (shown in Fig. 8c). The occlusal force was also larger than that in model MT7 (shown in Fig. 6f). However, the occlusal force at the second premolar under load 200 N was 34.5 N, which was slightly smaller than the occlusal force at the second molar on the natural dentition side. Under load 800 N, the occlusal force at the first molar was increased to 240 N. However, it was almost equivalent to that in model MT7 (shown in Fig. 6f). The occlusal force at the TMJ was slightly increased compared with that in model Im4567 (shown in Fig. 8c).
