Introduction: The implant angulation plays a very important role in the outcome of prosthetic and functional outcome. The conventional surgical stents uses a ring system to drill the pilot drill, only the CAD printed stents provides a guide sleeves for the sequential drill for implant placement. The Purpose of this Study: The purpose of the study was to fabricate a drill bit guide for the stent to transfer the angulation and implant placement planned using conventional method in prescribed drilling sequence. Material and Methods: A surgical stent with a threaded guide ring system was fabricated with internal drill bit guiding system. The interchangeable sequential drilling allows the drill bit to be in predetermined position throughout the procedure. Results: The surgical stent with the drill bit guiding system provided less than 1% error with a mean deviation of 0.48%. Conclusion: The drill bit guide fabricated has a complete limiting system and transfers the angulation and placement as desired with very minimal or no alteration, which enables the predetermined prosthetic outcome.
