A conventional complete denture is a removable prosthesis that replaces a missing set of teeth and surrounding tissue. It is well-adapted to the patient's oral cavity, utilizing the structures within the mouth to achieve retention and stability.
A partial denture is a removable option to replace missing teeth when an entire dentition replacement is not needed. It utilizes part of the remaining teeth and soft tissue to achieve retention, with retentive clasps or a base that fits into the spaces around the teeth.
Implant-supported dentures can be complete or partial. This type of denture combines the use of implants and traditional dentures to achieve better retention than could be acquired by a denture alone. Instead of solely relying on the patient's soft tissue anatomy for retention, the denture can hold on implants via attachments which arise from the implant.
For the case of partial dentures, the use of implants can relieve the stress placed on support teeth and remove the need for unesthetic clasps that would otherwise be required for retention.
