A Simple and Effective Technique to Fabricate Diagnostic and Surgical Stent

Abstract

Prosthodontic rehabilitation of completely edentulous arch with implant supported prosthesis requires a stent, to evaluate the relationship between anatomical structures and to aid in implant placement for successful treatment result. The lengthy treatment procedure where the clinician has to duplicate the existing denture for stent fabrication has created a need for an improved simple and time saving technique. This article thus describes fabrication of a surgical stent with acceptable retention, stability and teeth arrangement using simple and time saving lab procedures.

Projection Microstereolithography as a Micro-Additive Manufacturing Technology: Processes, Materials, and Applications

“…171 A stent, which is inserted into the vessel by a balloon catheter, occasionally with drug eluting, would seem to be a perfect tool to treat these diseases. 172 The microstereolithography process could be a potential approach to fabricating a stent with high resolution and complex features, which are required for the unique functions of a stent in the vessel. HDDA, an acrylate-based monomer, with 2 wt% of DMPA as a photoinitiator and 1 wt% of Tinuvin ® 327 as a photoabsorber, were used to demonstrate the capability of the microstereolithography technology for stent fabrication.…”
