“…Many factors contribute to the choice of an animal experimental model for testing bone regeneration strategies [ 7 ]. For mandibular bone regeneration, animal models are generally divided into small (including mice [ 8 ], rats [ [9] , [10] , [11] ], and rabbits [ [12] , [13] , [14] , [15] ]) and large (including dogs [ [16] , [17] , [18] , [19] , [20] , [21] ], goats [ 22 , 23 ], pigs [ 24 , 25 ], and monkeys [ 26 ]) animal models. Animal models usually differ in their mandibular CSDs.…”
