We study here the large-time behaviour of all continuous affine stochastic volatility models (in the sense of [15]) and deduce a closed-form formula for the large-maturity implied volatility smile. Based on refinements of the Gärtner-Ellis theorem on the real line, our proof reveals pathological behaviours of the asymptotic smile. In particular, we show that the condition assumed in [10] under ...

exist within the dolichocephalic population. Figure 13A illustrates a patient with a severe open bite and an acceptable smile line in which the occlusal plane should be tipped postero-superiorly. Since a great deal of posterior intrusive force will be required to reduce AFH and MPA, there will be a strong tendency toward anterior extrusion (see Fig. 12, Part 1). To prevent this undesirable effe...

PURPOSE To perform a comparative clinical analysis of the safety, efficacy, and predictability of two surgical procedures (ie, small incision lenticule extraction [SMILE] and femtosecond laser-assisted LASIK [FS-LASIK]) to correct myopia. METHODS Sixty eyes of 31 patients with a mean spherical equivalent of -5.13 ± 1.75 diopters underwent myopia correction with the SMILE procedure. Fifty-one ...

BACKGROUND The purpose of the present study was to discuss some new concepts of the desirable characteristics of smile tooth display. Due to the increasing application of cosmetic dental treatments, there is an increasing need for better understanding of the esthetic principles. MATERIALS AND METHODS In the present descriptive study, with 212 participants, included were patients with no histo...

The rehabilitation of patients requiring an esthetic smile demands a multidisciplinary approach. This clinical report describes a treatment plan for recovery aesthetics' smile of anterior teeth using ceramic prosthesis with zirconia structure. Initially, a review of aesthetic parameters, diagnostic waxing, mock-up and provisional restorations was performed. A contextual assessment of aesthetic,...

OBJECTIVE To evaluate the role of the posed smile in overall facial esthetics, as determined by laypersons and orthodontists. MATERIALS AND METHODS Twenty orthodontists and 20 lay evaluators were asked to perform six Q-sorts on different photographs of 48 white female subjects. The six Q-sorts consisted of three different photographs for each of two time points (pre- and posttreatment), as fo...

objectives: this study aimed to find the factors that affect dental esthetics and smile attractiveness in orthodontically treated patients according to laypeople’s judgment, and to determine whether there is any relationship between dental and smile esthetics. materials and methods: using the q-sort technique, 60 laypersons (30 males, 30 females) rated dental and smile photographs of 48 orthodo...

Aim: To evaluate different smile characteristics among dental students and find out gender- based association. Study design: Cross sectional observational study. Place duration: Prosthodontic Department of Lahore Medical And Dental College, Lahore, from 1st Jan 2022, till April 2022. Methodology: A total 260 were assessed for i.e.; line, arc, labiodental relationship number teeth visible during...

INTRODUCTION Esthetic analysis of dynamic functions such as spontaneous smiling is feasible by using digital videography and computer measurement for lip line height and tooth display. Because quantitative measurements are time-consuming, digital videography and semiquantitative (visual) estimation according to a standard categorization are more practical for regular diagnostics. Our objective ...
