Dear Editor,
We read with great interest the article by Xu et al, “Utilizing a Fully Digital Approach for Oral Squamous Cell Carcinoma Treatment and Zygomatic Implant–Based Rehabilitation for Maxillary Defects,” published in the Journal of Oral Implantology.1 The authors’ integration of advanced digital techniques with zygomatic implant–supported rehabilitation is commendable and represents a significant advancement in maxillofacial prosthetics. We want to offer some constructive comments and observations that might further enrich the ongoing discussion on this important topic.
The authors demonstrated meticulous planning and execution using 3D reconstruction, finite element analysis (FEA), and photogrammetry technologies. However, one critical aspect that could be elaborated upon is the long-term biomechanical behavior of zygomatic implants under functional loading. Whereas the FEA provides valuable insights into stress distribution immediately postplacement, it is worth noting that osseointegration and bone remodeling can alter the stress dynamics over time.2 Incorporating a follow-up analysis...
