An Acrylic Partial Denture (APD) is one option for replacing missing teeth and is also the most cost-effective treatment option. Dentists and dental technicians tend to design and construct acrylic partial dentures with little or no tooth support. A denture is a removable replacement for missing teeth and surrounding tissues. Two types of dentures are available -- complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.
