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.
