Dentures can be made as full (whole arch or whole mouth) or partial (replacing one or several teeth). All dentures are removable and have a tendency to move. To achieve stability, partial dentures need to be clasped to the natural teeth. But this can be unsightly. Precision attachments can allow the denture to be attached without showing the clasps.
Both partial and full dentures can be made to appear quite natural using the latest artificial teeth and acrylic. However, they are never an ideal substitute for natural tooth support or implants.
