“…For most, the cement gap ranged from 20 to 40 μm 4,8,9,16,29,30,34 . We chose these values based on studies accepting that an optimum cement thickness of 20 to 40 μm is generally specified to facilitate complete seating of the restoration and to allow for the film thickness of the cement 24‐26,37,38 …”

“…Furthermore, the development of Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) systems has largely eliminated the possibility of distortions during the production process. In recent years, the majority of authors have reported that the ideal cement gap thickness ranges from 20 to 40 μm 22‐26 . It is also accepted that for optimal results, the cement gap should be uniform 17 .…”

“…Another method to reduce film thickness is the timing of the prosthesis insertion. Film thickness can be increased by 10 mm (or more) for every additional 30 s once the cement was properly mixed [21,22].…”

Objective: to study the effect of using two cement types, with three different thicknesses, on stress levels and distributions within bone around implant premolar using three-dimensional Finite Element Analysis techniques. Materials & methods: A three 3D Finite Element models were built for this purpose. Threaded titanium dental implant was implemented in simplified geometry for jaw bone. While the crown geometry, was acquired by 3D scanner. Two cement materials (Zinc phosphate, Glass Ionomer), with three values of cement layer thicknesses (20, 40, and 60 mm) were investigated. Twenty-four case studies were reported within this research. Each case was analyzed under vertical and oblique loading at Palatal Cusp Tip and Central Fossa. Results: Linear static stress analysis was performed. The results of the model showed the superiority of 60 mm thickness cement layer over the other two thicknesses. Conclusions: Using thicker cement layer increase its lifetime, in addition to reducing the cortical bone Von Mises stress. While, the effect of cement layer thickness and type on spongy bone, is negligible.

“…In recent years, most authors have reported that the ideal luting space ranges from 20 to 40 µm. [22][23][24][25][26] Direct metal laser sintering (DMLS) is a promising technology to avoid distortions inherent to casting procedures. It involves the use of a high-power laser source, such as carbon dioxide laser, to fuse small particles of powdered alloy.…”

“…[24][25][26] The finding of improved retentiveness of the cements with the increased luting space of 40 µm may be explained by the fact that cement film thickness, viscosity, and cohesive strength are related to size or shape of filler particles and affect retentiveness and retrievability.…”

ÖZLazer sinterize yoluyla üretilen implant destekli kronların tutuculuklarında siman aralığının ve simanların etkisi Amaç: Bu çalışmanın amacı iki farklı siman aralığı ile yapılan implant destekli kronlar için kullanılan beş farklı simanın tutuculuk mukavemetini değerlendirmektir. Gereç ve Yöntemler:Standart titanyum dayanaklar dijital bir 3D lazer tarayıcı aracılığıyla tarandı. 100 standart metal alt yapı bir CAD/CAM sistem aracılığıyla iki farklı siman aralığı değerinde (20 ve 40 µm) tasarlandı. Alt yapılar beş farklı siman kullanılarak yapıştırıldı (n=10). Poly F (PF), GC FujiCEM (GCF), Rely X (RX), MIS Crown Set(MCS) and Multilink N (MN). Örnekler 24 saat bekletildikten sonra 1000 devir termal siklus uygulandı. Termal siklustan sonra örnekler universal test cihazında 0.5 mm/dk. hızla çekme testine tabi tutuldu. Test sonuçları iki yönlü varyans analizini takiben tamhane testleri kullanılarak çoklu karşılaştırmalarla analiz edildi (α=0.05). Bulgular:İstatistiksel analiz değerlendirildiğinde siman grupları arasında anlamlı farklılıklar görüldü (p<0.05). PF ve MN sırasıyla en yüksek ve en düşük tutuculuk kuvveti ortalamasına sahipti. RX ve MCS arasında anlamlı farklılık bulunmadı. 20 den 40µm ye artan siman aralığı, her siman grubu için tutuculuğu anlamlı ölçüde arttırdı (p<0.05).Sonuç: Çalışmada sunulan simanların klinisyenler için, implant dayanakların üzerine üretilen CAD/CAM metal alt yapılar için uygun siman seçimini belirlemede isteğe bağlı bir rehber olması amaçlanmıştır.
