A new technique has been recently added to CAD/CAM methods. These systems are called rapid prototyping. With these systems, metal framework of fixed partial dentures, facial prostheses, surgical models and stents, titanium implants can be obtained. In this technique which is an alternative to lost wax method, the virtual image of the restoration is transferred to the device. The laser beam is sintered the selected areas on the CrCo alloy powders and the restoration is produced layer by layer at single stage. In this clinical report, the technique, operating principle and fabrication process of rapid prototyping are described by fabricating the metal framework of a three unit metal supported porcelain bridge restoration which was decided to apply to the person with one teeth loss.

Protetik diş tedavisinde yaygın olarak kullanılan CAD/CAM yöntemlerine yakın zamanda bir yenisi eklenmiştir. ‘Hızlı Prototip Üretim Teknolojileri’ olarak adlandırılan bu sistemler ile sabit restorasyonların metal altyapıları, fasial protezler, cerrahi model ve stentler, titanyum implantlar elde edilebilmektedir. Kayıp mum tekniğine alternatif olan yöntemde, üretilecek olan restorasyonun sanal görüntüsü cihaza aktarılmakta ve lazer ışını ile toz halindeki Cr-Co alaşımı üzerinde, seçilmiş alanlar sinterlenerek, restorasyon tek aşamada, katmanlar halinde üretilmektedir. Bu olgu sunumunda, tek diş eksikliği nedeniyle üç üyeli metal destekli porselen köprü yapımına karar verilen vakada, restorasyonun metal altyapısının fabrikasyonu için kullanılan hızlı prototip üretim teknolojileri, çalışma prensibi ve fabrikasyon aşamaları açıklanmıştır.
