Purpose: The primary purpose of this study was to examine the clinical performance monolithic zirconia single crowns in terms short-term failure or complications. secondary detect originating flaws clinically failed find causes failure. Methods: A prospective cohort based on record evaluation and examination patients treated with tooth-supported performed Department Fixed Prosthodontics, Tohoku University Hospital, Japan. were prepared during follow-up period from April 2014 July 2018....
Cytoprotective effects of short-term treatment with grape seed extract (GSE) upon human gingival fibroblasts (hGFs) were evaluated in relation to its antioxidant properties and compared those a water-soluble analog vitamin E: trolox (Tx). GSE Tx showed comparable potential vitro against di(phenyl)-(2,4,6-trinitrophenyl)iminoazanium (DPPH; stable radical), hydroxyl radical (•OH), singlet oxygen (1O2), hydrogen peroxide (H2O2). Pretreatment or concomitant for 1 min protected hGFs from...
Zirconia-based dental restorations are becoming used more commonly. However, limited attention has been given to the difficulties experienced, concerning cutting, in removing when needed. The aim of present study was compare cutting efficiency diamond burs, operated using an electric high-speed handpiece, on zirconia (Zir) with those lithium disilicate glass-ceramic (LD) and leucite (L). In addition, evaluation burs Zir different thicknesses performed. Specimens were prepared 0.5, 1.0, 2.0,...
Purpose Evaluation of the clinical performance computer-aided design/computer-aided manufacturing-produced resin composite crowns (CAD/CAM crowns) on molars with a particular focus placement location. Methods A retrospective cohort study was performed based records patients CAD/CAM (June 2016 to March 2021). The hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated Cox proportional model evaluate effect tooth location complication type occurrence. Covariates included...
Abstract This study analyzed the impact of adhesive primer and light‐curing on polymerization kinetics urethane dimethacrylate‐based self‐adhesive resin cement combined with free radical reaction. Specimens were prepared by mixing paste or without primer. Subsequently, specimens light‐cured set light‐curing. The degree conversion (DC), Vickers hardness (Hv), concentrations repeatedly measured up to 168 h after curing initiation. Irrespective procedures, DC, Hv, concentration rapidly...
症例の概要:患者は69歳の女性.主訴は歯周炎による疼痛およびインプラントの破損と動揺による咀嚼困難であった.左右の臼歯欠損により咬合支持域の顕著な減少が起きたが,インプラントと延長ブリッジによる治療を行い,良好な予後を得ることができた.
目的：日本では高頻度の治療になりつつあるCAD/CAM冠であるが，歯学部におけるその教育システムは未だ確立途上である．東北大学歯学部では，平成28年度よりCAD/CAM冠治療の体系的な理解を目的とした模型実習を取り入れた．本稿では，その実習システムについて教育効果の考察を加えて紹介する．
