Digitally Guided Augmentation With an Autogenous Bone Cylinder-Digital CarroTrack Technique: A Case Report

Area of Science:

• Dentistry
• Oral Surgery
• Biomaterials

Background:

• Posterior mandibular tooth loss presents challenges for implant-prosthetic rehabilitation.
• Traditional bone grafting techniques can be invasive and lack precision.
• Digital planning and guided surgery offer potential improvements in accuracy and patient outcomes.

Purpose of the Study:

• To present a novel digitally guided augmentation technique using autogenous bone cylinders for posterior mandibular reconstruction.
• To evaluate the surgical and prosthetic outcomes of the Digital CarroTrack Technique.
• To assess the long-term stability and functional/aesthetic results of the treatment.

Main Methods:

• Digital planning integrated implant placement and guided bone augmentation using CBCT and intraoral scans.
• Autogenous bone cylinders were harvested using a trephine guided by a custom surgical guide.
• Bone cylinders were stabilized, augmented with bone substitute, and implants placed, followed by prosthetic rehabilitation.

Main Results:

• Successful bone reconstruction and stable peri-implant tissues were confirmed radiographically and clinically.
• The technique allowed for precise integration of digital planning with localized bone augmentation.
• Three-year follow-up showed stable hard and soft tissues with satisfactory functional and aesthetic outcomes.

Conclusions:

• The Digital CarroTrack Technique offers a precise, digitally guided method for autogenous bone augmentation in implant dentistry.
• This technique may provide a minimally invasive solution for reconstructing small alveolar ridge deficiencies.
• The approach demonstrates successful long-term functional and aesthetic rehabilitation for posterior mandibular defects.
