From: Impact of occlusal contact pattern on dental stability and oromandibular system after orthodontic tooth movement in rats

Figure 1

Experimental design. 40 male SD rats were randomly allocated into 4 groups with different established occlusal contact patterns after active orthodontic tooth movement of UM1. The force appliances were removed and the relapse distance, the general conditions, and the GCF were examined on day 1, 3, 5, and 7 of relapse. The left maxilla, masseter, and temporomandibular joint tissue were collected after the rats were sacrificed on day 7 for histological examinations and PCR.
