🖐🏾 Steps:-

👉 Step1: create a silicone index or patty of palatal to replace 

the thin uniform layer of the medium value of enamel composite (0.5mm) to act as a Matrix for remaining restoration.

 

This Enamel matrix should include the palatal and both sides of proximal walls

which can obtain using ( Matrix and wedge ). For example,

1. Unica anterior matrix system .

 

2. Celluloid matrix 

3. Mylar matrix strip.

 

👉 Step2: Proceeding to stratification of dentin composites layers as

∆ D3 in oblique direction replaced and thicker in cervical and thinner when go to incisal 1/3

∆ D2 in an oblique direction and covered D3 . and occupying about 60% of total volume with. ..

 and reach 2/3 of Cervical – incisal length.

∆ D1  in an oblique direction and covered D2 . and occupying about 90% of total volume with D3+2.

 

🌟 Note to leave about 0.5 to 1 mm in the incisal and proximal gap for opalescent mass.

Step3: opalescent mass applied

Step4: final layer will be a thin uniform layer of the medium value of enamel composite (0.5-0.7mm).

 

🌟 Note: We will talk about Steps 3 & 4 in Chapter 4 ( Mid )

 

S5: finishing & polishing, We will talk about Steps 5 in Chapter 10 ( Surface and Polishing )

⁦🖐🏾⁩  𝑺𝒆𝒄𝒂𝒏𝒅 𝒕𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆 𝒘𝒊𝒍𝒍 𝒃𝒆 : 𝑭𝒓𝒆𝒆 𝒉𝒂𝒏𝒅 ( 𝒄𝒐𝒏𝒆 𝒎𝒐𝒅𝒆𝒍𝒊𝒏𝒈 𝒕𝒆𝒄𝒉  ) .

 it's the Similar Steps as 𝑭𝒊𝒓𝒔𝒕 𝒕𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆 𝒊𝒔 ( 𝒗𝒂𝒏𝒊𝒏𝒊 ‘𝒔 𝒔𝒕𝒓𝒂𝒕𝒊𝒇𝒊𝒄𝒂𝒕𝒊𝒐𝒏 𝒕𝒆𝒄𝒉 ).

1. use stratification from central to surface as cones or areas, not layers 

2. used mainly n Lab, not Clinic.

🌟 𝑻𝒉𝒊𝒓𝒅 𝒕𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆 : 𝑺𝒊𝒎𝒑𝒍𝒊𝒇𝒊𝒆𝒅 𝒕𝒆𝒄𝒉 ..

◾️ It’s the same technique steps as 𝑭𝒊𝒓𝒔𝒕 𝒕𝒆𝒄𝒉𝒏𝒊𝒒𝒖𝒆 𝒊𝒔 ( 𝒗𝒂𝒏𝒊𝒏𝒊 ‘𝒔 𝒔𝒕𝒓𝒂𝒕𝒊𝒇𝒊𝒄𝒂𝒕𝒊𝒐𝒏 𝒕𝒆𝒄𝒉 ). but with less time and effort.

And less chromatic complex teeth.

Only using two layers of dentin composites or one layer.

Dx = D1, D2 

or

Dx = D1 only

 

and author recommended this Technique for beginners because it's required less effort, time and Material Consuming.

But 

The first tech is more complex but gives great esthetic results 🌟

Now the author gives us some Notes, which will help you to improve your esthetic treatment.

For two reasons :

1. make it easy, fast and efficient application of composite.

2. recover oxygen-inhibited layer after diamond bur used to make a correction on already polymerized composite.

This liquid is filler-free resin, so it will lead to decrease physical properties of the composite restoration.

 so 

Use it carefully and as minimum as the possible amount.

Just let the brush be moist, not wet 👌

You can use ( 𝐨𝐦𝐩𝐨𝐜𝐮𝐛, 𝐬𝐦𝐢𝐥𝐞 𝐥𝐢𝐧𝐞 ) to solve this problem. and make it easier to apply.
