A crown is used to cover a damaged tooth entirely. In addition to strengthening the damaged tooth, a crown can be used to correct its appearance, shape, or alignment.  

Bridges are used to replace one or more missing teeth. They fill the gap where there are no teeth. Bridges are cemented to natural teeth or implants that surround the space. These teeth, called supports, act as stabilizers for the bridge. This new tooth, which will fill the gap, is attached to the support crowns. 

• To prevent weakened teeth from cracking 
• To repair a broken tooth  
• To cover a dental implant 
• To cover a yellowed or misshapen tooth  
• To cover a tooth that has undergone root canal treatment 

 Why use a 3D Printer? 

Speed:  It is 6 times faster than its counterpart laser. Compared to the conventional method, which is another construction technique, one technician can have the daily limit of 50 members ready in just 15 minutes. 

Cost: The cost of one kilogram of weaving resin is estimated at 0.2 cents. 

Precision: Capable of sub-30 micron accuracy, especially in the crucial coil region, providing accuracy unmatched by other applications. 

Design and Planning 

Design is made on the digitally measured working model with auxiliary programs such as Exocad, 3Shape, DentalWings, ZirkonZahn, Bluesky Bio. 

 The margin line is drawn first, 

Then the entry direction is determined and the tooth design is completed in the appropriate morphology. 

Printing and Other Operations 

Preparation for printing 

Open your crowns and bridges in the nesting program you want to use. Position them so that the incisal area of the teeth is at the bottom, without affecting the most important part, the seating area (the collar area).

Post-Process 

Allow the model to clean compartment 1 of the MEDIFIVE washer with ethanol solution (96%) for 3 minutes. After completion, dry the model with a spray air gun 
. Allow the  
model washed and dried in the first compartment to be cleaned for 3 minutes in the second compartment of the MEDIFIVE washer containing  
ethanol solution (96%). After completion, dry the model with a spray air gun 
. Do not exceed a total cleaning procedure of 6 minutes as this may cause deterioration of printed objects. 
Tip: Resin residues can also be removed using a brush moistened with  
ethanol (96%). 

Important Note: PowerResins Burn resin does not require extra UV curing. 

Casting 

In dental restorations, the casting quality of the resin is of great importance as well as the accuracy of the 3D printed restorations in order to achieve the optimum restoration that perfectly fits the patient's tooth structure. 

PowerResins Burn is widely used in dental restorations made by Metal Casting and Emax press for 

Casting steps 

Rod clamping and cuffing 

A rod is a small diameter rod or tube made of wax, plastic or metal. Wax rods are preferred because they melt at the same speed as the wax structure and facilitate the escape of the melted wax.  

There are three basic requirements when it comes to routing; 

1. The rod must allow the melting wax to be removed from the mold.   
   2. It should ensure that the  
   melted metal is delivered  
   into the mold with minimum turbulence.  
   3. It must be able to remain molten for a longer period of time than the freezing of the metal that begins to fill the mold. 

Rod connection should be made while the wax model is on the day. 
The thickness of the rod should be as thick as the thickest section of the wax model. 

A distance of 6 mm must remain between the wax pattern and the base of the cuff Rod length should be kept as short as possible.

Plastering 

Mixing time in a vacuum mixer is 60 seconds. This information may vary according to ambient temperature. 

Room temperature > 28 ºC, mixing time in vacuum mixer: 40 seconds and poured into investment mold in 20 seconds. 

Room temperature < 28 ºC, mixing time in a vacuum mixer: 60 seconds and pouring into investment mold in 20 seconds. 

For liquid and water settings: 

Higher water = tighter fit 

Lower water = wider fit 

Revetment manufacturers usually send their own liquid with their packages. However, depending on the metal used, these liquid settings can be changed. 

Below is an example of fluid settings for Polyvest brand revetment: 

Little Mufla 

1 packet of revetman + 22 ml liquid + 14 ml water 

Orta Mufla 

2 packs of revetman + 43 ml liquid + 29 ml water 

Big Mufla 

3 packs of revetman + 65 ml liquid + 43 ml water
