بررسی تاثیر حضور ذرات اکسید تیتانیوم در جلوگیری از رشد دانههای NiTi در فرآیند تفجوشی [PDF]
یکی از مشکلات تفجوشی مواد نانو اندازه، رشد دانه در حین این فرایند است. از آنجایی که کاراییهای منحصر بهفرد مواد نانو تا زمانی که در محدوده اندازه زیر 100 نانومتر باشند، وجود دارد، بهمنظور جلوگیری از این پدیده و کاهش سرعت رشد دانهها راهکارهای مختلفی ...

Uprighting Mandibular Third Molar Using NiTi Wire [PDF]
If impacted teeth can be brought into occlusion, they should be brought into occlusion, especially in young patients. When the second molar is missing, saving the third molar becomes all the more important.
