Additive manufacturing (3D printing) has transformed dentistry by providing solutions with high precision and accuracy achieved through digital workflows, which facilitate the creation of intricate and personalized structures. Additionally, 3D printing promotes cost efficiency by reducing material waste and errors while enabling on-demand production, minimizing the need for extensive inventories. Recent advancements in 3D-printed resin materials have enhanced their clinical applications by improving mechanical strength, biocompatibility, esthetics, and durability. These innovations have facilitated the fabrication of complex and patient-specific structures, such as dental prostheses, surgical guides, and orthodontic appliances, while significantly reducing production time and material waste. Ongoing research and innovation are expected to strengthen resin properties, including strength, translucency, and durability, broadening their clinical applications. The ongoing evolution of 3D printing technology is poised to play a critical role in driving personalized treatments, streamlining clinical workflows, and shaping the future of dental care. This narrative review comprehensively examines the production techniques and clinical applications of 3D-printed photopolymer resins across various dental specialties, including prosthodontics, orthodontics, pediatric dentistry, maxillofacial surgery, periodontology, endodontics, and conservative dentistry. Additionally, the review provides insight into the transformative impact of these technologies on patient care, highlights existing challenges, and suggests future directions for advancing resin properties and their integration into routine dental practice.

The color stability of dental ceramics in the oral cavity is influenced by multiple factors, including the patient’s dietary habits and oral hygiene practices, which can affect the optical and surface properties of resin-containing dental restorative materials. The purpose of this study was to evaluate the effects of surface finishing procedures and simulated tooth-brushing on the surface roughness, surface gloss, and color stability of resin matrix ceramics before and after coffee immersion. Forty specimens were prepared from a resin matrix ceramic and divided into four experimental groups according to surface finishing procedures, coffee immersion, and simulated tooth-brushing. The surface roughness, surface gloss, and color stability of the tested material were measured, and the data were statistically analyzed at a significance level of p < 0.05. The surface finishing procedures, measurement times, and application sequences affected surface roughness, surface gloss, and color stability. The most significant color differences occurred after coffee immersion; however, tooth-brushing had a more significant effect on the surface roughness and surface gloss. Coffee caused perceivable and clinically unacceptable color differences in the resin matrix ceramics. Tooth-brushing had a positive impact on the tested parameters. This study presents a novel approach by integrating both chemical (coffee immersion) and mechanical (tooth-brushing simulation) degradation processes to assess their combined and isolated effects on a resin matrix ceramic material. The findings provide clinically relevant insights into how finishing procedures and oral hygiene may influence the long-term esthetic performance of such restorative materials.

Örneklere ait renk parametreleri beyazlatma ajanı uygulamasından önce ve sonra ölçüldü. Renk değişimi değerleri iki farklı formülle (ΔE00 ve ΔEab) hesaplandı. Sonuçlar istatistik anlamlılık düzeyi P

Introduction: Ectodermal dysplasia is a rare hereditary condition characterized by developmental defects in ectodermal-derived tissues and organs. In cases of ectodermal dysplasia, missing teeth (anodontia, hypodontia), conically shaped teeth, inadequate development of the alveolar crests, and loss of vertical dimension are observed. Due to the lack of most primary and permanent teeth during childhood, the esthetic and chewing functions of these patients need to be restored with a multidisciplinary treatment approach in the early period. This case report describes the rehabilitation of a child patient with ectodermal dysplasia using three-dimensional (3D) printed crown prostheses for existing upper central teeth and removable prostheses for additional missing teeth. Case Report: The treatment of a 10-year-old child patient who applied to Gazi University, Faculty of Dentistry, due to missing teeth was carried out and completed jointly by the Departments of Pediatric Dentistry and Prosthodontics. The extraoral examination of the patient, who was diagnosed with ectodermal dysplasia, revealed sparse eyebrows, hair, and eyelashes, dry and thin skin, and sagging and swollen lips. Intraoral examination identified only two conical-shaped maxillary central teeth. All procedures to be performed were explained to the patient and their parents, and their consent was obtained. As a result of the prosthetic analysis, it was decided to make a crown restoration for the existing teeth and an upper and lower removable prosthesis for the missing teeth. After tooth preparations, permanent resin crowns were fabricated using 3D printing technology and cemented onto the prepared teeth. The removable prostheses for the upper and lower jaws were completed using traditional methods and delivered to the patient, who was scheduled for follow-up appointments. Conclusion: Early multidisciplinary intervention is crucial for patients with ectodermal dysplasia starting from childhood due to significant tooth loss, aiming to restore both esthetics and functionality. The goal in designing prostheses is to preserve existing teeth, esthetically restore conical-shaped teeth, and prevent resorption of the alveolar ridges. The application of 3D printing in pediatric dentistry holds substantial potential, offering an aesthetically pleasing, durable, and cost-effective alternative for prosthetic restorations in child patients with ectodermal dysplasia.

Dijital iş akışının diş hekimliğinde giderek yaygınlaşmasıyla birlikte, bilgisayar yardımlı tasarım ve bilgisayar yardımlı üretim tekniklerine üç boyutlu baskı teknolojisi de dahil olmuştur. Günümüzde eksiltmeli üretimin yerini almaya başlayan bu teknoloji, kişiye özgü tasarımlar ve yüksek hassasiyetli çözümler sunarak diş hekimliğindeki tedavi süreçlerini hızlandırmakta ve klinik açıdan tatmin edici sonuçların elde edilmesini sağlamaktadır. Üç boyutlu baskı teknolojisiyle üretilen materyallerin implant destekli sabit protezlerde kullanımı, son yıllarda yeni bir uygulama olarak protetik diş tedavisinde yerini almıştır. İmplant destekli sabit protezlerde model ve kişisel ölçü kaşığı üretiminde kullanılmaya başlanan bu teknoloji, özellikle fotopolimer rezinlerle birlikte vat fotopolimerizasyon yöntemi aracılığıyla geçici ve daimi restorasyon üretiminde de yaygınlaşmaktadır. Bu alanda yapılan çalışmalar sonucunda fotopolimer rezinlerin başarılı performansları, implant destekli sabit protezlerde kullanımlarını daha etkin bir hale getirmiştir. Yöntemin ve materyallerin yeni olması sebebiyle literatürdeki mevcut eksiklik, ağız ortamının gereksinimlerini tam olarak karşılama konusunda henüz yeterli bilgi sunmamaktadır. Ancak, üç boyutlu ve dört boyutlu baskı teknolojilerindeki sürekli gelişmeler, gelecekteki çalışmalarla bu endişelerin giderileceği yönünde umut vadetmektedir. Bu derleme çalışmasında vat fotopolimerizasyon baskı teknolojisinin ve fotopolimer rezinlerin implant destekli sabit protezlerde kullanımı ile ilgili güncel literatür bilgisinin verilmesi amaçlanmıştır.
