دكتور لو سمحت احنا بالlower بننقص من السبشال تري ٢ ملي ده من الناحية ال buccal بس ولا كمان lingually ؟ عشان ندي مكان لل green stick compound

[@DrMahmoudRamadan]

Buccal and lingual all borders

[@osamaelnhas4209]

هو مش ممكن ال putty يثبت من غير adhesive ؟

[@DrMahmoudRamadan]

صعب يثبت من غيره وبيبقى معرض للإزالة أثناء ال final wash أو حتى الحركة التى تقلل من دقة الطبعة لذا يفضل تثبته

تمت الإجابة على الخاص يا دكتور 🌹

[@angelicafoster670]

can i make border molding using putty and secondary impression using light instead of medium?

[@DrMahmoudRamadan]

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.

[@dmsdental5595]

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

[@jihadbahaa6196]

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

[@jihadbahaa6196]

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 ?

[@DrMahmoudRamadan]

No wax spacer for Zno cases it must be closely fitted. You just relief the sensitive and sharp areas on diagnostic cast.

[@DrMahmoudRamadan]

I used different materials to give you more experience with several materials and techniques
