B-Guide System: Improving the Predictability of Complete-Arch Implant and Prosthetic Placement Using Fixed Prosthesis...

Area of Science:

• Dental Implantology
• Computer-Aided Implant Placement (CAIP)
• Prosthodontics

Background:

• Traditional static computer-aided implant placement (sCAIP) for complete-arch restorations often requires multiple surgical guides and clinical steps.
• Existing sCAIP protocols can increase the risk of soft tissue trauma and procedural complexity.
• There is a need for simplified protocols that enhance accuracy and reduce invasiveness in full-arch implant rehabilitation.

Purpose of the Study:

• To introduce and evaluate the B-guide technique for computer-aided implant placement (CAIP).
• To demonstrate how the B-guide integrates implant placement and interim prosthesis delivery into a single device.
• To assess the B-guide's potential to simplify procedures, minimize tissue trauma, and improve clinical efficiency in complete-arch restorations.

Main Methods:

• The B-guide was designed to function as both an implant osteotomy and placement guide, and an abutment placement and prosthesis pick-up mechanism.
• The guide remains in situ post-implantation, facilitating immediate interim prosthesis conversion.
• A case study involving a 55-year-old female patient undergoing complete-arch rehabilitation using the B-guide was presented.

Main Results:

• The B-guide technique successfully enabled immediate implant placement and loading in the presented case.
• The single-device approach minimized soft tissue trauma compared to traditional multi-guide protocols.
• Treatment complexity and time were significantly reduced due to the elimination of multiple guides.

Conclusions:

• The B-guide simplifies complete-arch implant procedures and enhances predictability by integrating prosthetic adaptation with implant placement, thereby reducing cumulative errors.
• The technique minimizes surgical complexity, reduces patient trauma, and improves prosthetic outcomes, leading to greater clinical efficiency.
• Successful implementation of the B-guide technique is highly dependent on the operator's expertise in preoperative planning and digital design.
