This question cannot be answered as asked. What kind of damage has the regulator sustained? Was the first stage damaged? Or one of the 2nd stage mouth pieces? Without knowing, advice about how to repair the device cannot be offered with any degree of reliability.
In any event, I would strongly recommend that you do not attempt to repair a regulator on your own. Regulators are a precision piece of dive equipment and should not be repaired except by qualified technicians. Please ring your regulator to your dive shop and let a qualified person deal with the issue. Do Not attempt to repair the regulator on your own.
