Bilaminar dual-purpose stent for placement of dental implants

Proper placement of implants in the posterior maxillary region with poor bone density is essential to obtain long-term success. In this article, the fabrication of a bilaminar dual-purpose stent that facilitates ease in implant placement with improved verification of implant positioning is described. The outer lamina is designed for use in the computed tomography evaluation, using radiopaque markers. The verification of implant alignment and positioning, according to the determined prosthesis, is also performed with this template after modifying it for surgery. The inner lamina is designed to accept 2 removable surgical acrylic resin stents with different guide channels that avoids the risk of surgical malpractice.
