Can bicuspid posts be reinserted after falling out?

Tooth #13 with post and crown. The post with crown fell out. The crown was in poor condition as explained by dentist one year ago. Can the old post be reinserted and new crown made? or is it better (of course more expensive) the pull tooth and do implant. I am a senior (mid 70') so would replacing post be adequate? Other wise no problem with teeth
