Background:
The evolution of digital dentistry has enabled the development of more predictable and less invasive protocols for bone augmentation and prosthetic rehabilitation. This case report introduces an integrated digital workflow combining the Digital CarroTrack technique with the "One-Step Crown" concept to optimize clinical outcomes and efficiency.
Case Description:
A patient requiring alveolar ridge reconstruction and implant therapy was treated using the Digital CarroTrack technique. This approach utilized precise digital planning to simultaneously harvest an autogenous bone cylinder from the surgical site and reposition it for augmentation, eliminating the need for a secondary donor site. Following implant placement, a "one-step crown" protocol was implemented. A provisional restoration served as a template for soft tissue contouring, and its emergence profile was directly replicated in a pre-designed definitive crown. The bone cylinder fixation screw was retrieved during the final prosthetic delivery, ensuring a streamlined workflow.
Results:
In this case, the integrated digital approach facilitated accurate bone cylinder placement and implant positioning. At the 2-year follow-up, clinical and radiographic examinations confirmed excellent stability of both hard and soft tissues, with no marginal bone loss or soft tissue recession. The procedure reduced the number of clinical stages, treatment time, and patient morbidity compared to traditional methods.
Conclusions:
This case report suggests that the combination of the Digital CarroTrack Technique and the One-Step Crown concept may represent a promising, minimally invasive, and time-efficient approach for complex implant-prosthetic cases. Digital planning appeared to support procedural accuracy while reducing surgical invasiveness and the number of clinical stages. Further prospective studies with larger patient groups, objective volumetric measurements, longer follow-up, and dedicated cost-effectiveness analyses are needed to confirm the predictability, clinical effectiveness, and potential economic benefits of this approach.
