Abstract
BACKGROUND: Facial aging involves not only soft tissue laxity but also progressive bony resorption, particularly in the maxilla and mandible. Current non-invasive aesthetic modalities primarily target soft tissues, neglecting skeletal changes that contribute to volume loss and structural descent. OBJECTIVE: To propose the hypothetical role of multiwavelength diode laser (MWDL) in stimulating osteogenesis via controlled thermal delivery to the periosteum, offering a novel, non-invasive strategy for counteracting facial bone resorption. METHODS: This clinical commentary discusses MWDL's mechanism-targeting the periosteal layer using 755, 808, and 1064 nm wavelengths (N.CORE 3D (previous version of Fortra), Classys Inc., Seoul) to deliver 43°C-46°C heat. A case study of a 70-year-old female receiving 16 sessions over 4 years was included. Cortical bone thickness was measured pre- and post-treatment using dental radiographs. RESULTS: Modest increases in cortical bone thickness were observed: from 3.4 to 3.51 mm (left) and from 3.14 to 3.37 mm (right), suggesting possible periosteal osteogenic stimulation. CONCLUSION: MWDL may represent a promising adjunct to soft tissue rejuvenation by addressing age-related skeletal decline. While early findings are encouraging, controlled trials are needed to validate efficacy, optimise protocols, and define long-term safety.
