00:14 - Title: Class IV resin-based composite restoration using Free-hand technique (1)
00:22 - Class IV resin-based composite restoration on a mandibular lateral incisor
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
11:00 - Restoration: Place, adapt, shape & contour the composite material increment
11:24 - Restoration: Light-cure
11:31 - Restoration: Place, adapt, shape & contour the composite material increment
12:09 - Restoration: Light-cure
13:10 - Restoration: Remove the celluloid matrix strip & wedge
13:13 - Finishing & polishing
13:16 - Finishing & polishing: Finishing: Proximal surface: No. 12 blade, Flame or needle diamond points, or finishing & polishing discs, finishing strips
13:37 - Finishing & polishing: Finishing: Facial, lingual & proximal surfaces: Finishing & polishing discs
13:59 - Finishing & polishing: Finishing: Check margins with the tip of the explorer
14:06 - Finishing & polishing: Finishing: Facial, lingual & proximal surfaces: Finishing & polishing discs
15:43 - Finishing & polishing: Finishing: Lingual surface: Football diamond point or finishing & polishing discs
15:53 - Restoration evaluation: Check contact
15:58 - Restoration evaluation: Check for overhang
16:05 - Finishing & polishing: Finishing: Proximal surface: Finishing & polishing discs
16:48 - Restoration evaluation: Check margins for gaps, ditches, excess & overhang. Check anatomy & contour
16:54 - Finishing and Polishing: Polishing: Rubber points or disposable polishing discs
17:23 - Restoration evaluation: Check margins for gaps, ditches, excess & overhang. Check anatomy & contour
18:09 - Restoration evaluation: Check contact
18:14 - Restoration evaluation: Check for overhang
18:17 - Check occlusion
