RPD, CD & CPD are the 3 types of dentures that can be made.
VRPD is the quickest & easiest & cheapest replacement option for a missing tooth.
Wherever a RPD can be made a CPD can also be made.
The advantage of a CPD over an RPD is its steardiness.
However the most problem with a complete denture is the lower denture does not get a good retention. No matter whomever, best of the dentist also does the job.
That’s why it is always advised to replace any missing tooth at its earliest possible.
