Metal framework reinforcement in implant overdenture fabricated with a digital workflow and the double milling technique: A dental technique.

An implant-supported overdenture is a cost-effective option that enhances both appearance and function. Advances in computer-aided design and computer-aided manufacturing (CAD-CAM) technology have simplified the procedures for denture fabrication, reducing time and costs while increasing patient satisfaction. However, fractures in overdentures are often caused by misalignment of the occlusal registration, excessive force, material wear, and insufficient space between the denture base and the attachment. Reinforcing the overdenture with a metal framework enhances mechanical strength, stability, and durability. A novel technique with a double milling procedure of a single resin disk using a digital workflow for a maxillary overdenture reinforced with a selective laser melting metal framework should increase the mechanical strength and accuracy of the implant overdenture.
