Dental implants restore missing teeth but face high infection rates. This research investigates zirconia crown design, bacterial leakage, and material strength. Using microscopy and mechanical testing, it identifies a three-step sealing method for implant screw access holes, reducing infection risk and improving long-term implant success and patient confidence.

This research demonstrates that jaw surgery corrects functional impairments, not just appearance. Studying hundreds of patients shows that correcting jaw disproportions eliminates speech distortions, improves chewing and breathing, and enhances quality of life. The findings challenge the view of jaw surgery as cosmetic, reframing it as vital medical care.
