Clinical case report: Immediate full-arch implant placement and loading technique using a fiducial-free dynamic...

Area of Science:

• Dentistry
• Surgical Technology
• Oral Implantology

Background:

• Dynamic navigation surgery typically relies on dental fiducial markers for accurate implant placement.
• Extracting all teeth and performing bone reduction presents a challenge for conventional dynamic navigation techniques.
• Accurate alveoloplasty and implant positioning are crucial for full-arch fixed prostheses.

Purpose of the Study:

• To describe a novel technique for accurate bone reduction using dynamic navigation in full-arch dental implant cases.
• To overcome the limitations of fiducial markers in patients requiring complete maxillary tooth extraction and alveoloplasty.
• To demonstrate the application of a prosthetically-driven guide for dynamic navigation in complex full-arch rehabilitation.

Main Methods:

• A novel prosthetically-driven guide was designed for a dynamic navigation system.
• The guide facilitated accurate alveoloplasty and dental implant placement in a patient requiring full maxillary extraction.
• The technique obviated the need for traditional X-Clips by incorporating the alveoloplasty level directly into the guide.
• Immediate loading of a provisional prosthesis was performed.

Main Results:

• The novel technique enabled accurate bone reduction and precise dental implant placement using dynamic navigation.
• The prosthetically-driven guide successfully guided alveoloplasty and implant positioning without fiducial markers.
• The limitations associated with dynamic navigation in full-arch implant cases were overcome.
• The patient received a provisional prosthesis immediately after implant placement.

Conclusions:

• A novel technique using a prosthetically-driven guide allows for accurate bone reduction and implant placement with dynamic navigation in full-arch cases.
• This method overcomes the challenge of fiducial marker use when all teeth are extracted, improving treatment predictability.
• Dynamic navigation can be effectively applied to complex full-arch implant rehabilitation, enhancing surgical accuracy and patient outcomes.
