00:38 - Preparation
00:41 - Preparation: 1. Remove sharp edges
00:57 - Preparation: 1. Remove sharp edges: using flame-shaped diamond points or carbide bur
01:11 - Preparation: 2. Beveling
01:14 - Preparation: 2. Beveling: using flame-shaped diamond points
01:53 - Preparation: 2. Beveling: Why? a. Increase retention
02:22 - Preparation: 2. Beveling: Why? b. Enhance esthetics
03:30 - Preparation: 2. Beveling: How? Long bevel (60 degrees)
03:56 - Preparation: 2. Beveling: When? A. Enamel present. b. Not high stress-bearing area
05:16 - Restoration
05:18 - Restoration: Place the celluloid matrix strip & wedge
05:41 - Restoration: Apply the adhesive system (one-step self-etch system): Selective etch technique
05:50 - Restoration: Apply the adhesive system (one-step self-etch system): Selective etch technique: 1. Acid etch enamel
06:40 - Restoration: Apply the adhesive system (one-step self-etch system): Selective etch technique: 2. One-step self-etch (all-in-one) adhesive
07:22 - Restoration: Apply the adhesive system (one-step self-etch system): Selective etch technique: Light-cure the adhesive
07:30 - Restoration: Place, adapt, shape & contour the composite material increment
08:06 - Restoration: Place, adapt, shape & contour the composite material increment. Make sure you view from all surfaces (facial, lingual, incisal & interproximal)
09:36 - Restoration: Light-cure
09:42 - Restoration: Place, adapt, shape & contour the composite material increment
10:13 - Restoration: Remove proximal excess using the tip of the dental explorer held at 45 degrees
10:20 - Restoration: Place, adapt, shape & contour the composite material increment
10:54 - Remove proximal excess using the tip of the dental explorer held at 45 degrees

If you want to move it up, you add composite. To move it down, you will need to remove some of the tooth structure by stripping or removing by a diamond finishing point. I do not really recommend moving the location of the contact a lot because it may be an area of black area or food stagnation when the embrasure becomes larger. But is all depends on the amount you need to remove.

اشكرك يا دكتورة فيديوهاتك بقيت ادور عليها عشان اتعلم.. ممكن تعملي ل
Back to back c2 composite ♥️
عفوا. بإذن الله أحطها في القائمة الفيديوهات الجديدة.
أعذروني السنة مني قادرة أنزل فيديوهات بانتظام لظروف صحية.
ممتنة شكرا
الف سلامة ❤️❤️

As always beautiful explained but i would ask about your tip when i have long conatact incisogingivally ( contact located at the middle third ) … what you recommend to corrected to push the contact at incisal third safely … may i ask if you post free hand restoration of lower canine 😅😅 i am interested in canines
Thank you. Depending on the tooth's shape, you can either add composite or do minor contouring to the natural tooth to give an illusion that the contact is lower. However, this needs to be seen clinically to evaluate where the modification needs to be done and what to do. I will add the canine to the list of videos to record 😊.
@@drafnanoalzain i mean if i wanna push the contact more incisallly located do i have other than strip option to move it incisally ? Thx
