A novel device for template-guided surgery of the zygomatic implants

Zygomatic implants are indicated for the rehabilitation of the severely atrophic maxilla. Similar to standard implant placement, gaining an optimal position of the zygomatic implants is essential for a predictable prosthetic-driven treatment outcome. Stereolithographic templates, either bone-supported or mucosa-supported, have been used to install zygomatic implants in the planned position based on computer-assisted planning. However, there is no effective mechanism to physically control the drilling trajectory for the zygomatic implants. Therefore, deviation between the actual and planned implant position is inevitable. A novel device designed to increase the precision of the guided surgical placement of zygomatic implants that guides the osteotomy from the entry point to the exit point, allowing optimal positioning, is presented herein.
