Üç Boyutlu Eklemeli İmalat ile Üretilen Seramik Restorasyonlar
Özet
Bu bölümde, eklemeli üretim teknolojisinin protetik diş tedavisindeki klinik kullanımı ve tarihsel gelişimi ele alınmıştır. Geleneksel ve eksiltmeli üretim tekniklerine kıyasla daha fazla tasarım esnekliği, düşük malzeme israfı ve hasta özelinde kişiselleştirme sunan bu yöntem, 3D yazıcılarla katmanlı üretim esasına dayanmaktadır. Reçine, metal ve seramik gibi biyouyumlu malzemelerle uyumlu olan bu teknoloji, tam ve bölümlü protezlerden geçici ve kalıcı restorasyonlara kadar geniş bir uygulama alanına sahiptir. Üretim süreci dijital tarama, CAD tasarımı, baskı ve bitirme işlemlerini içerir. Klinik uygulamalarda marjinal uyum, mekanik dayanıklılık ve estetik başarı açısından umut verici sonuçlar sunmaktadır. Ancak yüzey pürüzlülüğü, renk stabilitesi ve mekanik direnç gibi bazı kısıtlamalar bulunmaktadır. Gelecekte biyomalzeme geliştirme ve yapay zeka destekli tasarım yazılımlarının entegrasyonu ile bu teknolojinin etkisinin daha da artması beklenmektedir.
This chapter discusses the clinical applications and historical development of additive manufacturing technology in prosthodontics. Compared to traditional and subtractive production techniques, this method—based on layer-by-layer fabrication using 3D printers—offers greater design flexibility, reduced material waste, and personalized treatment options. Compatible with biocompatible materials such as resins, metals, and ceramics, additive manufacturing has a wide range of applications, including complete and partial dentures, as well as temporary and definitive restorations. The production workflow involves digital scanning, CAD-based design, printing, and post-processing stages. Clinically, additive manufacturing provides promising outcomes in terms of marginal adaptation, mechanical durability, and aesthetic performance. However, certain limitations remain, including surface roughness, color stability, and variations in mechanical strength. With the advancement of biomaterials and the integration of artificial intelligence-assisted design software, the impact of this technology is expected to increase further in the near future.
