Manufacturing Removable Partial Dentures by Digital Methods

Abstract

Some problems on design and production stage during the construction of conventional partial removable dentures could be solved with today's technology. Nowadays, digital techniques have reformed the production of partial removable dental prostheses (PRDPs). Recently, several digital methods are available in the request for RPD product including subtractive and additive techniques. Digital techniques increase the variety of materials that can be used for RPD production. The aim of this article was give information about the clinical application of the removable partial protheses produced by digital methods.

Dijital Metodlar ile Hareketli Bölümlü Protez Yapımı

Abstract

Geleneksel hareketli bölümlü protezler üzerinde yapılan çalışmalar sonucunda, dizayn ve üretim aşamalarında kusurlar olduğu belirtilmiştir. Bu kusur ve eksiklikler göz önünde bulundurularak, geleneksel hareketli bölümlü protezlerin günümüz teknolojisinin imkanları ile birleştirilerek üretilmesi amaçlanmıştır. Son zamanlarda teknolojinin gelişmesiyle beraber, dijital tekniklerle üretilen hareketli bölümlü protezler prostodontik alanda devrim yaratmıştır. Hareketli bölümlü protez üretimi için eklemeli veya eksiltmeli yöntem olan birçok dijital teknikten yararlanılabilmektedir. Güncellenmiş üretim teknikleriyle beraber kullanılan materyallerinde yelpazesi genişlemektedir. Bu makalenin amacı, güncel dijital yöntemler kullanılarak üretilen hareketli bölümlü protezlerin klinik uygulamalarda umut verici sonuçlar ortaya koyduğunu göstermektir.
