Abstract (2. Language): 
İt is not always possible to surgically replace the tissues of the congenital or required facial defects. In those situations, which affect the patient's sociopsychologic situations, prosthetic treatment is necessary. The conventional prosthesis producing techniques have many handicaps for patients, clinicians and technicians. Acquiring the data of the patient's face using three dimensional scanning techniques provides to shorten this process. The computed tomography (CT), magnetic resonance imaging (MR1). laser surface scanners and optical modeling systems are currently used. Prototyping of the facial prosthesis is made by rapid prototyping (RP) technique. Stereolithography is one of the RP techniques. This article investigates the computer assisted design of facial prostheses.

Abstract (Original Language): 
Doğumsal veya kazanılmış yüz defektleri bulunan hastaların bu defektlerinin cerrahi yolla tamamen kapatılması her zaman mümkün olmamaktadır. Hastaların sosyo-psikolojik durumlarını önemli ölçüde etkileyen bu durumlarda dcfckllerin protetik olarak kapatılması gerekmektedir. Protezlerin hazırlanmasında kullanılan geleneksel yöntemler hasta, hekim ve teknisyen açısından türlü zorluklar taşımakta ve uzun zaman gerektirmektedir. Hastaya ait ölçümlerin çeşitli üç boyutlu görüntüleme yöntemleri kullanılarak yapılması ve bunların bilgisayara aktarılmasıyla üç boyutlu modellerinin elde edilmesi bu zorlu süreci oldukça kısaltmakladır. Günümüzde bu amaçla bilgisayarlı tomografi(BT) ve manyetik rezonans (MR) görüntüleme yöntemlerinin yanı sıra lazer yüzey tarayıcılar ve optik modclleme yöntemleri de başarıyla kullanılmaktadır. Elde edilen verilerden üç boyutlu modellerin oluşturulması işleminde hızlı prololipleme (RP) yöntemi kullanılmaktadır. Stereolithografi (SL), RP tekniklerinden biri ve en yaygın olarak kullanılanıdır. Bu makalede yüz protezlerinin üretilmesinde bilgisayar destekli sistemlerin kullanım alanları incelenmiştir.
