Buccal and lingual all borders
لو التراي perforated و عاوز اخد الامبريشن بلايت ربر بيز ينفع اسيب الهيفي في ال fitting surface without scratch?
تمت الإجابة على الخاص يا دكتور 🌹
هو مش ممكن ال putty يثبت من غير adhesive ؟
صعب يثبت من غيره وبيبقى معرض للإزالة أثناء ال final wash أو حتى الحركة التى تقلل من دقة الطبعة لذا يفضل تثبته
Is it c silicone putty sir??
Border molding putty c. Silicone
Final wash medium c. Silicone
👍❤️
can i make border molding using putty and secondary impression using light instead of medium?
Yes you can. But medium wash is better because it makes moderate displacement of the mucosa during impression registration. This is beneficial in increasing support and fitting of denture during function.
Which type of adhesive you have used for the condensation rubber base , Doctor. what i mean , is an adhesive for addition pvs compatible for the condensation type? Thanks in advance
Used a transparent nail polisher as an adhesive

dr please , for the zinc oxide secondary impression , do we make wax spacer and stoppers in the special tray like in this case ? thanks in advance
and why you used different types of primary and secondary and border molding materials for the upper and lower arches ? just for education ? or according to the case and how to decide the material impression suitable for the case ?
No wax spacer for Zno cases it must be closely fitted. You just relief the sensitive and sharp areas on diagnostic cast.
I used different materials to give you more experience with several materials and techniques
