Smile is an object-oriented, equation-based, hybrid modeling and simulation environment. The focus of this paper is the extension (Smile/M) of the Smile system to Modelica, a new modeling language currently being defined in an international collaboration effort. An overview of this language, which may well become a quasi-standard in the simulation community, is given. Interfacing Smile to Model...

Timeless human esthetics implies a sense of beauty, a pleasing impulse, naturalness, and a youthful appearance relative to one’s age. The goal for esthetic treatment should be an enhanced but natural appearance that imparts a vibrant and believable appearance to the patient. This should be our goal in dental esthetics: a result that would be considered “bright, beautiful, but believable.” Nowad...

Purpose To investigate ex vivo potentially different corneal biomechanical properties after small-incision lenticule extraction (SMILE) versus LASIK for myopic correction. Methods Thirty human donor corneas were subjected to either myopic SMILE or femtosecond laser-assisted LASIK. Donor corneas were assigned to six investigative groups: Group A, -3.00 D (diopters) SMILE; Group B, -8.00 D SMIL...

The aim of this study was to compare smile attractiveness between one, three, and four premolar extraction protocols in patients with Class II division 1 subdivision malocclusions and to analyse the aesthetic influence of buccal and posterior corridor widths on smile attractiveness. The sample consisted of posed smile photographs obtained from 66 subjects, divided into three groups according to...

The study addresses the emergence of the social smile in two different sociocultural contexts during the first 12 postnatal weeks. We examined different eliciting mechanisms like mutual gazing, maternal smile during mutual gazing, and reciprocal maternal and infant imitation of smiling. In co-constructivist theories of emotional development, all of them are considered social mechanisms that fos...

BACKGROUND The smile perception of patients is not strictly related to standardized protocols and technical implications which certainly affect clinicians' decisions. The absence of maxillary lateral incisors could affect smile esthetics either with treatment or not. The aim of the present study was to investigate if different perceptions on altered smiles due to missing maxillary lateral incis...

How do people detect trustworthiness in others? Some researchers have shown that research participants trust smiling faces more than non-smiling faces. We examined cultural differences in this “smile effect.” We investigated whether three elements of a smile (smile intensity at the eyes, smile intensity at the mouth, and facial symmetry) would differently influence American and Japanese partici...

Purpose. To evaluate decentration following femtosecond laser small incision lenticule extraction (SMILE) and sub-Bowman keratomileusis (SBK) and its impact on higher-order aberrations (HOAs). Methods. Prospective, nonrandom, and comparison study. There were 96 eyes of 52 patients who received SMILE and 96 eyes of 49 patients who received SBK in this study. Decentration was calculated 6 months ...
