INTRODUCTION In this study, we evaluated the clinical usefulness of miniscrews as orthodontic anchorage. We examined their success rates, analyzed factors associated with their stability, and evaluated patients' postoperative pain and discomfort with a retrospective questionnaire. METHODS Seventy-five patients, 116 titanium screws of 2 types, and 38(More)
INTRODUCTION The purpose of this study was to evaluate root proximity as a risk factor for the failure of miniscrews used as orthodontic anchorage. METHODS We used dental radiographs and 3-dimensional computed tomography images to examine 216 titanium screws in 110 patients. Each screw was classified according to its proximity to the adjacent root.(More)
Odontogenic ameloblast-associated (ODAM) and amelotin (AMTN) are secreted by maturation stage ameloblasts and accumulate at the interface with enamel where an atypical basal lamina (BL) is present. This study aimed at determining and quantifying the ultrastructural distribution of ODAM and AMTN at the cell–tooth interface. Ultrathin sections of enamel(More)
INTRODUCTION Skeletal anterior open bite is a difficult problem to correct in orthodontic treatment. In adults, treatment of severe skeletal anterior open bite consists mainly of surgically repositioning the maxilla or the mandible. Recently, molar intrusion by using skeletal anchorage has been developed as a new strategy for open-bite treatment. In this(More)
BACKGROUND Trelagliptin is a novel once-weekly oral DPP-4 inhibitor. We assessed the efficacy and safety of trelagliptin versus the daily oral DPP-4 inhibitor alogliptin in Japanese patients with type 2 diabetes. METHODS We did a randomised, double-blind, active-controlled, parallel-group, phase 3, non-inferiority study at 26 sites in Japan. We included(More)
Anterior open bite is often caused by a downward rotation of the mandible and/or by excessive eruption of the posterior teeth. In such cases, it is difficult to establish absolute anchorage for molar intrusion by traditional orthodontic mechanics. This article reports the successful treatment of a severe skeletal anterior open-bite case using titanium screw(More)
The junctional epithelium (JE) adheres to the tooth surface, and seals off periodontal tissues from the oral environment. This incompletely differentiated epithelium is formed initially by the fusion of the reduced enamel organ with the oral epithelium (OE). Two proteins, odontogenic ameloblast-associated (ODAM) and amelotin (AMTN), have been identified in(More)
INTRODUCTION Recently, miniscrews have been used to provide anchorage during orthodontic treatment, especially for incisor intrusion. Miniscrews during incisor intrusion are commonly used in implant orthodontics. Traditionally, effective incisor intrusion has been accomplished with J-hook headgear. In this study, we compared the effect of incisor intrusion,(More)
BACKGROUND In patients with type 2 diabetes, improving adherence to medication is important in order to maintain favourable glycaemic control during long-term treatment and, thus, prevent the onset or aggravation of complications. SYR-472 is a novel once-weekly oral DPP-4 inhibitor for type 2 diabetes, which could be a treatment option when clinicians seek(More)
OBJECTIVE To quantify the treatment effects of interradicular miniscrew anchorage and to confirm the validity of the clinical usage of interradicular miniscrews in the distal movement of maxillary molars in nonextraction treatment. MATERIALS AND METHODS Twenty-four maxillary molars were moved to the distal using miniscrews placed in the interradicular(More)
