Case Report. Analysis of Discrepancy Index (DI) and Cast-Radiograph Evaluation (CRE)

Orthodontist specializing in temporary anchorage devices and biomechanics. Founder of Beethoven Orthodontic Center and Newton's A Inc. in Hsinchu, Taiwan. Inventor of OrthoBoneScrews (OBS), a skeletal anchorage system widely used in contemporary orthodontics.

Over 30 years of clinical experience utilizing miniscrews and bone plates for maximum anchorage in complex orthodontic cases. Pioneer in developing simplified bone screw placement techniques achieving high success rates and minimal patient discomfort. Developer of non-surgical treatment protocols for severe malocclusions traditionally requiring orthognathic surgery, using strategic OBS placement for three-dimensional tooth movement control.

International lecturer and educator teaching OBS techniques through workshops and clinical demonstrations worldwide. Publisher of the International Journal of Orthodontics (JDO), distributed internationally. Conducts multi-day intensive training programs at Beethoven clinic allowing participants to observe live OBS placements and clinical workflows. Known for exceptional patient volume management, treating hundreds of active cases simultaneously with high efficiency and quality outcomes.
