Computer Aided Full Arch Restoration by Means of One-Piece Implants and Stackable Guide: A Technical Note

Area of Science:

• Dentistry
• Oral Surgery
• Biomedical Engineering

Background:

• Full maxillary edentulism presents complex rehabilitation challenges.
• Immediate loading of dental implants offers functional and esthetic benefits.
• Computer-guided surgery improves implant placement accuracy.

Purpose of the Study:

• To present a novel computer-guided protocol using titanium-reinforced stackable surgical guides.
• To detail the workflow for post-extractive implant placement and immediate loading.
• To evaluate the efficacy of the stackable guide system in full arch rehabilitation.

Main Methods:

• 3D digital scans of existing prosthetics and dental arches were acquired.
• Virtual planning integrated STL and DICOM files for implant positioning.
• Stackable surgical guides with a fixed base and removable components were fabricated.
• Implant surgery and immediate prosthetic loading were performed using the guides.

Main Results:

• The protocol successfully rehabilitated a patient with full maxillary edentulism using one-piece implants.
• Implants achieved a minimum insertion torque of 35 Ncm.
• No surgical complications were reported during the procedure.
• The stackable guide system facilitated seamless transition from digital planning to surgery and restoration.

Conclusions:

• The developed computer-guided protocol with titanium-reinforced stackable surgical guides is effective for post-extractive implant placement and immediate loading.
• The fixed base template ensures a stable reference point throughout the workflow.
• This method enhances predictability and efficiency in full arch dental implant rehabilitation.
