| Summary, etc. | Aim: The current study aimed to assess the effect of fabrication technique on the internal fit and marginal integrity of zirconia reinforced lithium silicate crowns. <br/>Methodology: A typodont tooth for mandibular second molar was prepared according to the criteria of all ceramic crown preparation. The prepared tooth was duplicated into 20 epoxy dies that was subsequently classified into 2 groups; Group 1 (n=10) milled zirconia reinforced lithium disilicate (ZLS) crowns and Group 2 (n=10) pressed ZLS crowns. Internal fit was measured by the replica technique while marginal fit was measured before and after cementation using stereomicroscope.<br/>Results: Concerning marginal integrity, Pressed ZLS crowns recorded higher marginal gap than milled samples, before and after cementation, yet the difference was not statistically significant. Meanwhile, milled ZLS crowns recorded higher internal gap than that of pressed ZLS crowns. However, the difference was not statistically significant (p=0.206).<br/>Conclusions: Within the limitations of the study, the fabrication technique of ZLS crowns has no effect on the marginal integrity and internal fit of the crowns. The marginal and internal gaps achieved by the crowns across both groups were within the clinically acceptable range. |

| Summary, etc. | تهدف الدراسة الحالية إلى تقييم تأثير تقنية التصنيع على الملاءمة الداخلية والسلامة الهامشية لتيجان سيليكات الليثيوم المدعمة بالزركونيا. <br/>تم تحضير سن تيبودونت يماثل الضرس السابع للفك السفلى وفقا لمعايير جميع تحضيرات التاج الخزفي. تم نسخ السن المحضر إلى 20 قالب إيبوكسي تم تصنيفها لاحقًا إلى مجموعتين؛ المجموعة 1 ( ن = 10) التيجان المخروطة بالزركونيا الليثيوم ديسيليكات والمجموعة 2 ( ن = 10) التيجان المضغوطة بالزركونيا الليثيوم ديسيليكات. تم قياس الملاءمة الداخلية بتقنية النسخ المتماثلة بينما تم قياس الملاءمة الهامشية قبل وبعد اللصق على قالب الايبوكسى باستخدام المجهر المجسم. <br/>فيما يتعلق بالسلامة الهامشية، سجلت تيجان ZLS المضغوطة فجوة هامشية أعلى من العينات المطحونة، قبل وبعد التدعيم، إلا أن الفرق لم يكن ذا دلالة إحصائية(ع = 0.963). وفي الوقت نفسه، سجلت تيجان ZLS المطحونة فجوة داخلية أعلى من تلك الموجودة في تيجان ZLS المضغوطة. ومع ذلك، لم يكن الفرق ذو دلالة إحصائية (ع = 0.206).<br/>اوضحت النتائج انه ليس لتقنية تصنيع تيجان ZLS أي تأثير على السلامة الهامشية أو الملاءمة الداخلية للتيجان. وكانت الفجوات الهامشية والداخلية التي حققتها التيجان في كلا المجموعتين ضمن النطاق المقبول سريريا. |
