Biocompatibility is important for the 3D printing of resins used in medical devices and can be affected by photoinitiators, one key additives process. The choice ingredients must considered, as toxicity varies depending on photoinitiator, unreacted photoinitiator may leach out polymerized resin. In this study, use ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate (TPO-L) a resin was considered application device production, where cytotoxicity, colour stability, dimensional accuracy, degree...
Abstract Various materials have been introduced for the three-dimensional (3D) printing of dentures. In this study, color stability and surface physicochemical properties 3D-printed denture base resins with four types nanofiller particles were evaluated. Al 2 O 3 , ZnO, CeZr, SiO nanofillers added to a 3D printable base-resin matrix subjected digital light processing. The specimens immersed in Coke, coffee, black tea, or distilled water 6 days. For assessment differences, samples analyzed...
Dental composite resins are widely used in dental restorations. However, their clinical application is limited by the occurrence of secondary caries. Strontium-modified phosphate-based glass (Sr-PBG) a material known to have sustainable bacterial resistance effect. The mechanical properties (in particular, flexural strength, modulus elasticity, and hardness) materials determine function. Therefore, this study aimed investigate ion-releasing as well effect bioactive resin composites...
The elderly population with dementia is rapidly growing in South Korea. aim of this study was to investigate the relationship between and oral health 197 subjects aged ≥65 years. questionnaire included questions on subjective status, concern, status behavior, mastication ability, Oral Health Impact Profile-14 (OHIP-14), Korean Dementia Screening Questionnaires (KDSQ). examination conducted by a single dentist evaluate upper or lower denture use, determine numbers remaining functioning teeth,...
The aim of this study was to investigate the element composition and grain size commercial dental instruments used for ultrasonic scaler tips, which are composed stainless-steel materials. differences in mechanical properties wear resistances were compared. samples classified into 4 groups accordance with manufacturer, Electro Medical Systems, 3A MEDES, DMETEC OSUNG MND, compositions each tip analyzed micro-X-ray fluorescence spectrometry (μXRF) field-emission scanning electron microscopy...
Abstract Dental composite resins are widely used in dental restorations. However, their clinical application is limited by the occurrence of secondary caries. As strontium-modified phosphate-based glass known to have long-term antibacterial properties, this study, we incorporated a microfiller at 3, 6, and 9 wt.% concentrations into commercially available resin investigated mechanical properties (flexural strength, elastic modulus, microhardness), ion release characteristics, color resultant...
본 연구의 목적은 치주 조직의 유도 재생에 사용되는 3D 프린터로 제작된 흡수성 차폐막의 물리적 및 생분해성특성을 비교하는 것이었다. 세 가지 유형의 차폐막(β-TCP가 함유되지 않은 제품 2종과 β-TCP가 함유된 1종)이 고려되었다. 형태와 성분 구성은 EDS (energy-dispersive X-ray spectroscopy)와 함께 주사 전자 현미경(FE-SEM)으로 분석되었다. 기공도 기공 크기는 Micro-CT를 사용하여 측정하였다. 또한 인장 강도, 생분해성 시험이 수행되었다. 통계적 분석은 강도에서 일원배치분산분석 (one-way ANOVA)을 시행하였고, 사후분석으로 Tukey’s test를 시행하였다(p<0.05). 분석을 통한 SEM 이미지의 결과는 모든 그룹에서 C, O가 존재하는 격자 구조의 선형 층을 보여주었다. 일부 그룹에서는 Ca, P에서 약간의 차이가 있었다. 강도는 유의한 차이를 보였으며(p<0.05), 생분해성은 β-TCP를 함유한 그룹이...
