Fixation Base and Dental Guides for Single-Session Prosthesis Placement

Dental guides are fabricated in advance based on patient-specific 3D images and anatomical data. These guides pre-establish the precise spatial relationships and geometric references needed for implant placement, eliminating the need for complex intraoperative measurements and adjustments. The guides are custom-manufactured before the surgical procedure to match the patient's unique anatomy.

The installation procedure is divided into distinct modular steps: (1) placing the fixation base on prepared bone surfaces, (2) attaching the dental guide to the fixation base, (3) using the guide for precise implant placement, and (4) removing the guide after implant insertion. This segmentation allows each component to be optimized independently and simplifies the overall complex procedure into manageable stages that can be completed efficiently in one session.

All planning and measurement work is completed beforehand using patient-specific 3D imaging and digital modeling. The dental guides are manufactured in advance with pre-calculated implant positions, angles, and depths. This preliminary preparation eliminates time-consuming intraoperative decision-making and allows the actual surgical procedure to be completed rapidly in a single session.

The dental guide acts as an intermediary device that transfers the pre-planned implant positions from the digital model to the actual surgical site. The guide includes geometric reference points and physical constraints that automatically ensure precise implant placement without requiring complex real-time measurements or adjustments during surgery, thereby reducing procedural time.

The dental guide incorporates highly precise geometric reference points and features only at the specific locations where implant placement is needed, rather than requiring high precision throughout the entire device. The fixation base provides stable localization at the bone surface, while the guide attaches to it and provides localized precision guidance for drill placement. This local quality approach achieves high measurement precision where needed without requiring the entire device to be overly complex.

The dental guide is created as a physical copy or replica of the virtual implant plan derived from patient-specific 3D imaging. The guide's geometric features directly correspond to the pre-calculated implant positions, angles, and depths from the digital model. This copying process transfers the precision of the digital planning to the physical surgical guide without requiring the guide itself to contain complex measurement or calculation mechanisms.
