Introduction: Rehabilitation of partially edentulous patients using implant-supported fixed prostheses is now a predictable treatment and of proven success in the long term. Objective: The purpose of this paper is to outline a systematic approach to prosthetic rehabilitation of partially edentulous patients, exemplified by a clinical case with bone reconstruction and recovery of the vertical di...

Wavelength-locking by a volume holographic grating (VHG) is reported for a diode laser bar with 49 single mode emitters, fitted with a dual-axis collimation phase-plate for smile elimination and excellent beam pointing correction. The much-improved VHG feedback with the ultra-collimated array beam gives 100% wavelength locking at 975 nm over a 17°C temperature range and external cavity lengths ...

PURPOSE To compare dry eye after small incision lenticule extraction (SMILE) and femtosecond laser-assisted LASIK (FS-LASIK) for correcting myopia. METHODS CENTRAL, Embase and PubMed were searched in November 2016. All randomized controlled trials (RCTs) and prospective cohorts that compared dry eye after SMILE with FS-LASIK were selected. RESULTS Five cohorts and one RCT were identified fo...

OBJECTIVE This study aimed to quantitatively assess the relationship of smile esthetic variables with various types of malocclusion, and identify the cephalometric factors affecting smile measurements. METHODS This retrospective study included 106 patients who were treated with retention at the orthodontic department of Taipei Medical University Hospital. Hard-tissue variables were measured u...

The role of a glucagon/cAMP-dependent protein kinase-inducible coactivator PGC-1α signaling pathway is well characterized in hepatic gluconeogenesis. However, an opposing protein kinase B (PKB)/Akt-inducible corepressor signaling pathway is unknown. A previous report has demonstrated that small heterodimer partner-interacting leucine zipper protein (SMILE) regulates the nuclear receptors and tr...

OBJECTIVE To test the null hypothesis that there is no clinically significant difference between the post-orthodontic treatment images of smiles of subjects captured by clinical photography and the smiles of the same subjects obtained from digital video clips. MATERIALS AND METHODS Clinical photographs and digital video captures were obtained from 48 orthodontically treated patients. An updat...

INTRODUCTION Esthetics and attractiveness of the smile is one of the major demands in contemporary orthodontic treatment. In order to improve a smile design, it is necessary to record "posed smile" as an intentional, non-pressure, static, natural and reproducible smile. The record then should be analyzed to determine its characteristics. In this study, we intended to design and introduce a soft...

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...
