Dentures can be of two types. Partial Denture and Complete Denture. Partial Denture id recommended when you have multiple teeth missing but also have multiple remaining teeth in the mouth which can act as anchors to artificial teeth of the partial denture. Complete Denture is recommended when there are no teeth present and this complete denture is often associated with two small implants on the lower arch to improve retention.
Both Partial and Complete dentures can restore your mouth to full set of teeth to give you esthetic and functional end goal.
