Fiber Reinforced Overdenture
A challenge for Dental Professionals is fabricating an esthetic, yet strong and functional prosthesis when there is limited vertical space. This case presentation details a patient who fractured a new mandibular overdenture yet was unwilling to compromise on esthetics with the repair.
The patient had limited space to place denture teeth, acrylic, and attachments over the implant superstructure. After reviewing the options, the dental team chose to remake the denture with eFiber fiber reinforcement in order to provide strength but not compromise esthetics. The patient presented with a fractured mandibular overdenture retained by three Locator attachments on a CAD-CAM implant supported titanium bar. Rather than repairing the fractured prosthesis, the decision was made to fabricate a new stronger prosthesis utilizing reinforcement.
The challenge to the dental team was to increase prosthesis strength while maintaining esthetics in minimal acrylic and interocclusal space. Woven fibers or metal compromise denture esthetics and require thicker areas of acrylic to hide the reinforcement. The material chosen needed to be translucent for esthetics while allowing optimal positioning to resist fracture forces and provide strength.
eFiber and Perma Mesh were chosen to strengthen the overdenture. Unidirectional eFibers are stronger than multi-directional fiber or metal yet is translucent to maintain maximum esthetics. eFiber does not require special tools or expensive equipment and is easy to use. The fiber uniquely bonds to denture base acrylic and both acrylic and composite denture teeth to allow for esthetic and optimal placement of the reinforcement, ideally perpendicular to the fracture forces.
The Dental Team chose to bond the strong unidirectional eFiber to the denture teeth, placing the strongest (unidirectional) fiber at the optimal (junction of denture tooth and acrylic) position, perpendicular to the masticating fracture forces.
