Recommended Resin: SG01
Shining 3D offers SG01 for surgical guide application. SG01 is a biocompatible rigid polymer resin with minimal flex, allows it to maintain its form during dental surgeries.
This application guide demonstrates each step from 3D scanning to 3D printing on AccuFab printers with normal resin tank (1 bottle SG01 resin).
Use the current workflow to ensure a high satisfaction result.
Scan
Dental design software requires a digital impression with Aoralscan intraoral scanners of the patient’s dentition anatomical data in order to design surgical guide applications.
Before designing for the surgical guide, the anatomy of the patient’s hard tissue structure with CBCT is required.
Design
For the surgical guide application, we suggest users to use exocad to design the surgical guide and make sure to select the .STL file to export the correct file type compatible with AccuWare import.
Adjust the design settings to ensure the safety, correct and comfort for patient’s use.
Review the CBCT with the mandibular nerve if needed.
Import the intraoral scanned data and the CBCT into exocad and manual align for the data to match.
Note: This is very important for the path of insertion in the further treatment.
Choose the implant and place in the patient’s anatomy. Most of the implant can be found in implant library to match allowing for virtual design in exocad.
Draw the desired area to cover arch when designing for the surgical guide.
When the design is finished, export .STL and start slicing in AccuWare.
One-Click Printing *Use the latest AccuWare and FabWare version
Choose the one-click printing type- surgical guide after you import the data and find in data-processing stage. The support will be automatically added and give you an optimum option. For each application, support parameter will be slightly different, so please choose the correct support if you need manual adjusting. Delete any support which has been added on the sleeve and intaglio.
Post-process
Part Removal
You can use FabWash or scrapping tools to remove the printed parts.
Washing
Please place the ceramic platform for cutting on FabWash first.
If you use IPA with ≥75%, we suggest using the FabWash pre-set time
If you use IPA with ≥90%, we suggest decreasing 1 or 2 min
Hand Wash
Please use soft brush for cleaning, prevent hard brush which may cause surface damage
Please wash in ≥75% IPA for 1-2 min.
Drying
You can leave the models on FabWash for air dry overnight or the blow dry the model, make sure there is no resin residues and alcohol staying on surface.
Residues remain will be shown in reflection under room light. Please repeat the cleaning process if the above is shown
Curing
Place the well-cleaned models in FabCure 2 with support facing downwards.
FabCure 2: 5 min
Place the models for 1-2 hours for a better stability. The models must be cured to match the optimal mechanical properties and achieve the biocompatibility to ensure the patient’s safety and comfort.
Note: The cured SG01 will changed from transparent to cleared yellow. If the colour gets deeper, please stop curing immediately to avoid overcure.
Remove supports
Use the flash cutters remove tools to cut the supports 1mm below the attach points to the surgical guide. Post-cured surgical guide might be brittle, please use other grinding tools or cutting disks to remove.
Polishing
Use sandpaper to smooth the support adding area for patient’s comfort. Use pumice and high shine to polish the surgical guide for final product.
Fitting
Fit the finished surgical guide on model to test the path of insertion and retention. Place the surgical guide sleeves on the model for the surgery use.
Note: use IPA for a final cleaning procedure. Autoclave is not suggested in surgical guide procedure
