OBJECTIVES To evaluate and compare the influence of posterior gummy smile on the perception of smile esthetics by orthodontists, general-dentists and laypersons. STUDY DESIGN A frontal photograph of a smile with normal gum exposure was chosen and manipulated digitally using Adobe Photoshop C3 to generate three further images with posterior gum exposure of 4, 6 and 8mm. These four images were ...
Esthetics and smile characteristics from the layperson's perspective: a computer-based survey study.
BACKGROUND The paradigm shift from occlusion to esthetics places more emphasis on the subtle relationships among the teeth and the interplay with the soft tissues. The authors of this study quantified the ideal and maximum acceptable deviations for smile characteristics. METHODS The authors created a survey by using a digital image editing software package, which enabled raters to manipulate ...
Purpose. To compare the change of anterior corneal higher-order aberrations (HOAs) after laser in situ keratomileusis (LASIK), wavefront-guided LASIK with iris registration (WF-LASIK), femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK), and small incision lenticule extraction (SMILE). Methods. In a prospective study, 82 eyes underwent LASIK, 119 eyes underwent WF-LASIK, 88 eyes ...
PURPOSE To comparatively investigate the clinical outcomes, vector parameters, and corneal aberrations of small incision lenticule extraction (SMILE) with a triple centration technique and corneal wavefront-guided transepithelial photorefractive keratectomy (PRK) for the correction of high astigmatism. METHODS This retrospective, comparative case series study included 89 eyes (89 patients) th...
Ectasia After SMILE: Correct Interpretation of Biomechanical Hypothesis We read the case report by Mattila and Holopainen on bilateral ectasia after SMILE in the July 2016 issue with great interest.1 It is evident that preoperative examination with topography, tomography, and slit-lamp examination needs to be strictly followed by surgeons before small incision lenticule extraction (SMILE), LASI...
PURPOSE Optimal treatment strategies for advanced natural killer/T (NK/T)-cell lymphoma have not been fully defined. We compared the safety and efficacy of DDGP and SMILE regimens for advanced NK/T-cell lymphoma in a randomized controlled, multicenter, and open-label clinical trial. EXPERIMENTAL DESIGN Patients were newly diagnosed in stages III-IV and had performance scores in 0 to 2. Six cy...
Inspired by recent advances in psychological studies on motion-based face perception, we examine in this paper, from the viewpoint of pattern recognition, the identity information behind a smile. A smile video database is collected, from which we compute dense optical flow fields and generate features by summing up the flow fields over time during the neutral-to-smile period. We investigate the...
Gummy smile cases are always esthetically demanding cases. This article presents a case treated with an interdisciplinary treatment approach and Digital Smile Approach (DSA) using Keynote (DSA), to predictably achieve an esthetic outcome for a patient with gummy smile. The importance of using questionnaires and checklists to facilitate the gathering of diagnostic data cannot be overemphasized. ...
