Can anyone suggest what technology and 3D printing material is most suitable for printing of dental models?

I'm looking for a 3D printer for applications in the dental field, for printing digital dental models (not for itra-oral use parts). Resolution and finish are the main requirements that we consider necessary. Any suggestion?
