“…Son yıllarda, diş hekimliğindeki teknolojik gelişmelerle birlikte üretim teknolojilerine dâhil olan 3 boyutlu yazıcılar, sağlık alanıyla birlikte diş hekimliği pratiğine de yeni bir bakış açısı getirmiştir. 1 Üç boyutlu yazıcılar, freze kullanılan konvansiyonel üretimin aksine daha hızlı ve düşük maliyetli üretim imkânı sunmaktadır. 2 Ayrıca bu yöntemle, minimum insan müdahalesi gerektirerek basit bir üretim protokolü altında yüksek hassasiyette çıktı elde edilebilmektedir.…”

Son yıllarda konvansiyonel üretimden farklı olarak daha hızlı ve düşük maliyetli üretim imkanı sunan 3 boyutlu yazıcılarda kullanılan geçici ve daimi kuron materyallerinin üretici firmanın önerisi dışında farklı polimerizasyon süresi ve yöntemi hakkında literatürde sınırlı veri ve çalışma mevcuttur. Bu çalışmada, 3 boyutlu baskılı metakrilik asit ester bazlı geçici ve daimi kuron reçinelerin farklı yöntemlerle sertleşme protokollerinin Vickers sertlik değeri üzerindeki etkisinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmada VarseoSmile Crown Plus (VSC, n=90) ve VarseoSmile Temp (VST, n=90) materyallerinden stereolitografi formatında disk şeklinde (ø: 8 mm, kalınlık: 2 mm) 3 boyutlu çıktılar (n=180) elde edilmiştir. Daha sonra diskler Otoflash, Valo Cordless ve Labolight LV-III cihazlarında üretici firma önerilerine uygun olarak polimerize edilmek üzere randomize şekilde 3 gruba ayrılmıştır. Elde edilen disklerin Vickers yüzey sertlikleri hesaplandıktan sonra tek yönlü varyans analizi ve "post hoc" Duncan testleri kullanılarak istatistiksel değerlendirme yapılmıştır (p<0,05). Bulgular: En yüksek yüzey sertlik değeri VSC'nin Bego-Otoflash ve Valo ışık cihazı kullanılarak polimerize edildiği gruplarda gözlenmiş olup, bu gruplar arasında istatistiksel olarak anlamlı farklılık bulunmamıştır (p>0,05). Ancak diğer grupların yüzey sertlik değerleri arasındaki farklılık istatistiksel olarak anlamlı bulunmuştur (p<0,01). Sonuç: VSC ve VST esaslı 3 boyutlu kuron materyallerinin bu reçineler kullanılarak tamir edildiğinde polimerizasyon amacıyla üretici firmanın önerdiği Otoflash cihazı yerine Valo ışık cihazının kullanılması benzer dayanıklılıkla sonuçlanacaktır.Anah tar Ke li me ler: Kuron; polimerizasyon; sağlamlık testleri ABS TRACT Objective: Except for the manufacturer's instructions, there are limited data and studies about different polymerization times and methods of temporary and permanent crown materials produced by 3D printers, which offer faster and less expensive production options than conventional production. The aim of this study was to evaluate the effect of different polymerization methods on the Vickers hardness value of three-dimensional printed methacrylic acid ester-based temporary and permanent crown resins. Material and Methods: In the study, threedimensional printouts (n=180) were obtained from VarseoSmile Crown Plus (VSC, n=90) and VarseoSmile Temp (VST, n=90) materials in the form of disks (ø: 8 mm, thickness: 2 mm) in standard tessellation language format. The discs were then randomly divided into 3 groups to be polymerized in Autoflash, Valo Cordless and Labolight LV-III devices in accordance with the manufacturer's instructions. After calculating the Vickers surface hardness of the obtained disks, statistical evaluation was performed using one-way analysis of variance and post-hoc Duncan tests (p<0.05). Results: The highest surface hardness value was observed in the groups where VSC was polymerized using Bego-Otoflash and Valo light device and there was no statistically signifi...

Background Tissue engineering, despite decades of focus on medical applications, has yielded minimal progress in this respect, drastically dissimilar to the avalanche of efforts undertaken. There's no even a conceptual approach, besides recently sprung up "Linear Volumetric Printing". Which, however, has not yet been tested even on biocompatible materials. While existing technologies are limited to creating 3D structures that are either two orders of magnitude larger or three orders of magnitude slower to produce than required for medical-grade bioprinting. Objectives This study proposes a novel approach to overcome these limitations and achieve the creation of fully functional medical grade tissue-engineered constructs. Methods We propose a multi-pronged approach: 1. Define Minimal Requirements: Establish the essential characteristics of bare minimum requirements for fully functional tissue-engineered constructs. 2. Pulsed Holographic Bioprinting: Develop a pulsed holographic submicron-scale photopolymerization system for generating intricate scaffolds (including vascular networks and stromal compartments), based on a mathematical hologram model; 3. Multi-Material Volumetric Printing: Develop a methodology for multi-material volumetric photopolymerization to create complex structures. 4. Cellular Delivery Systems: Design "service conductive dispersion-framework systems" to efficiently deliver cells and bioactive substrates throughout the bioengineered tissue strata, combined with wireframe pseudo-stroma; 5. Gas Transport Culture Medium: Develop a novel gas transport perfusion culture medium for optimal growth and maturation of bioengineered tissues/organs prior to implantation. Expected outcomes We believe that this combined approach will address existing limitations and pave the way for the creation of fully functional bioengineered tissues and organs for medical applications, offering some utterly fantastic prospects.
