Abstract

Nowadays dental implants are recognized as the best option for replacing missing teeth. Passive fit of the prosthetic structures is the most essential element for successful treatment in implant supported prostheses. An implant-supported restoration cannot be passively fitted unless the three-dimensional position of the implants in the mouth is accurately transferred to the cast. To do this, the impression must be taken correctly, the impression technique must be selected correctly, the proper impression material must be used, and the relationships between the teeth and surrounding structures must be accurately determined. The impression material, the impression technique, the position, angle, and depth of the implant, the dimensional stability of the plaster, the die system, and the length of the impression copings all have an impact on the accuracy of the impression. In implant-supported prostheses, there are two methods for taking impressions: traditional and digital. In this review, the impression methods used in implant prostheses will be assessed in terms of the number of implants used, the materials used for the impression and splint, the coping design, the implant angle, and the type of connection between the implant and abutment.

İmplant Üstü Protezlerde Ölçü Yöntemleri ve Ölçü Doğruluğunu Etkileyen Faktörler

Abstract

Günümüzde dental implantlar doğal dişlerin yerine geçebilecek en iyi seçenektir. İmplant destekli protetik restorasyonlarda pasif uyum tedavinin başarısı için en önemli faktördür. Pasif uyumlu implant destekli restorasyonlar, doğru ölçü tekniği ve uygun ölçü materyali kullanılarak doğru ölçü alınması, dişlerin komşu yapılarla ilişkilerinin doğru belirlenmesi ve ağız içi yapıların modele doğru aktarılması ile sağlanabilir. Ölçünün doğruluğu, ölçü materyalinden, kullanılan ölçü yönteminden, implantın pozisyonu, açısı ve derinliğinden, kullanılan alçının boyutsal stabilitesinden, kullanılan day sisteminden ve ölçü kopinglerinin uzunluğundan etkilenir. İmplant üstü ölçü yöntemleri geleneksel ve dijital olarak ikiye ayrılabilir. Bu derlemede implant üstü ölçü yöntemlerinin implant sayısı, ölçü materyalleri, splint materyali, koping tasarımı, implant açısı ve implant-abutment bağlantı şekli yönleriyle karşılaştırmalı olarak değerlendirilmesi amaçlanmıştır.
