Analysis of esthetic smiles by using computer vision techniques.

Properly aligned teeth and a beautiful smile are the twin goals of orthodontic treatment. Unfortunately, a change in the smile arc is sometimes an unintended consequence of proper alignment. We used 3-dimensional dental models and visualization techniques, including curve-fitting and image-processing algorithms, to analyze smile arcs with respect to different parameters. The results show that smile consonance depends greatly on the conversational distance and the angle of elevation between the viewer and the smile.

An unusual complication from esthetic injection of liquid silicone into the forehead.

PURPOSE: To report a case of migration of liquid silicone into the upper eyelid. DESIGN: Interventional case report. METHODS: A 32-year-old woman had an injection of liquid silicone into the subcutaneous tissue of the forehead. She developed a cystic mass in the upper eyelid 2 days postinjection. An excisional biopsy was performed. RESULTS: The mass lay in the Müller's muscle, and its base adhered to the tarsus. The mass ruptured during dissection, revealing a yellowish turbid fluid. Histopathologic findings showed lipogranulomatous reaction. CONCLUSIONS: Liquid silicone injection to the forehead may promote formation of a cystic mass in the upper eyelid.
