What happened to those whose tombs were open?

in Matthew 27:52-53 > tombs were opened, and the bodies of many saints who had fallen asleep > were raised. And coming forth from their tombs after his resurrection, > they entered the holy city and appeared to many. Source Is there any teaching or opinions on what happened to these saints after they appeared to many? Did they literally raised from the dead with their body or did they appear only as spirits? Did their body go back to the tombs afterwards or were assumed? What is the catholic belief?
