Expanded polytetrafluoroethylene implant is usually considered as a wonderful implant for chin cosmetic augmentation with no or less bone resorption compared with solid silicone implant. However, one severe bony erosion in expanded polytetrafluoroethylene chin augmentation was found in our clinical work. We consider that the possible reason about severe bone resorption in such situation is most relative to the mentalis muscle hyperactivity, rather than the kinds of materials. We also strongly advise that genioplasty is suitable for the cases with mentalis muscle hyperactivity caused by a dentofacial deformity.
与固体硅胶植入物相比，膨体聚四氟乙烯植入物通常被认为是用于下巴美容隆突的理想植入物，骨吸收少或无骨吸收。然而，在我们的临床工作中，发现一例膨体聚四氟乙烯隆下巴术后出现严重骨侵蚀。我们认为，这种情况下严重骨吸收的可能原因与颏肌活动亢进关系最大，而非材料种类。我们还强烈建议，对于牙颌面畸形导致颏肌活动亢进的病例，正颌手术是合适的。
