With 3D printing, you can deliver All-on-X dentures in a single appointment, using temporary resin materials for quick, cost-effective implants.This guide will take you step-by-step through scanning, design, fabrication, and polishing.
Caution: Please note, this guide is specifically intended for use with Shining3D equipment only. It is not applicable to other brands or models, and using it with non-Shining3D devices may result in inaccurate instructions or improper setup.
Scan
We recommend using the Shining 3D Elite intraoral scanner for scanning All-on-X edentulous cases.
The Elite scanner, equipped with the IPG scanner tip, over 90% accuracy in capturing intraoral data of post-surgery soft tissues.
The Elite intraoral scanner combines the functions of both photogrammetry and traditional
intraoral scanning into one device, making it easier and more convenient for dentists and dental designers to collect and merge data.
This integrated approach is also more comfortable for patients immediately after dental surgery, as it avoids the need for traditional dental impressions. The Elite scanner provides a fast and comfortable data collection method, enhancing both efficiency and patient experience.
Intraoral scanning data standard
1. Intraoral scan-- pre-operative scan
Prior to surgery, use Elite to capture comprehensive pre-operative data, including scans of both the upper ,lower jaws and bite scan. This ensures the subsequent design software can generate a highly accurate provisional restoration, providing a solid foundation for the final implant procedure and improving clinical outcomes.
2.Intraoral scan--post-operative scan
Elite is a TWO-IN-ONE system combining intraoral photogrammetry and intraoral scanning that allows for soft tissue scanning and capturing implant positions.
Then, the soft tissue data and implant positions are aligned within a single scanning workflow, collecting all the necessary data for full-arch fixed restorations.
Post-operative soft tissue scanning can be challenging if the area is not properly cleaned. Uncleaned blood may interfere with the accuracy of the soft tissue scan, making it more difficult to align the soft tissue with the implant positions.
The scanning of soft tissue implant positions and data alignment can be completed within the same software workflow.
Upon finishing the soft tissue scan, mount the coded scan bodies onto the multi-unit abutments, selecting the appropriate lengths for each position and ensuring the ends are centrally aligned.
Subsequently, scan the coded scan bodies to accurately capture the implant positions. Finally, export the data and import it into the design software for further processing.
Design
The pre-operative occlusal relationship, aligned with the soft tissue, will be transferred to the provisional restoration design in exocad software. In some cases, especially for final restorations, Elite can complete the entire data acquisition and alignment, then directly import the data into exocad for design.
Caution:
1. A thickness larger than 1.5mm around the implant position is the optimum thickness for wearing the all-on-x application with a pressure less than 0.3mm on gingiva issuggested.
2. During the design stage, avoid occlusal high points to ensure even force distribution in occlusion. Try to avoid placing the implant in positions 13/23, as the canines are typically the contact points during protrusion and retrusion.
3. Avoid free-end partial design.
4. We suggest using Rosen screws to tighten the All-on-X system without the need for a Ti- base. This method ensures no breakage, no loosening and requires only hand torque.

Points need to be in caution for printing all-on-x:
1. Ensure that all incisal edges are properly supported. Add supports to the lower points to increase accuracy along the edges. Especially when the area is marked in dark red.
2. Orient the occlusal surface to face the platform, while avoiding the addition of supports on the fitting surface to maintain accuracy.
The post-processing stage includes washing, drying, support removal and curing.
Post-process
The post-processing stage includes washing, drying, support removal and curing.
Note: Mini material can be used for the standrad plateform.
Washing
We suggest you use Shining 3D FabWash for the post-cutting and post-washing. But if you don’t have FabWash, we suggest you could use scrappers to remove the model and then use ultrasonic machine or hand wash with suggested procedure below.
1. FabWash
If you are using the standard ceramic platform, select "Cut and Wash" from FabWash for a streamlined process. For the small ceramic platform, be in caution when removing the model with scrapers.
2. Ultrasonic Machine
Place the model in a beaker with enough IPA (≥75%) to fully cover it. Use an ultrasonic machine (150-500W) for approximately 2 minutes. Afterward, transfer the model to a clean beaker with uncontaminated IPA and wash it again. Avoid washing for too long, as it can affect the model's accuracy and strength.
* If you have a stronger powered ultrasonic machine, please consider to decrease the washing time.
3. Hand Wash
Use a soft brush to gently clean the teeth surface and fitting surface, then repeat the washing process for 1 minute. Perform the same procedure again using clean IPA for a final rinse.
Drying
Use a compressed air gun to thoroughly dry the cleaned model, ensuring that the surface is completely dry and free of excess IPA and residue. If any residue is still visible (with obvious reflections), repeat the cleaning procedure. After the model is fully dried, allow it to sit for 5 minutes before proceeding with the next steps.
Post-curing
Place the model in FabCure 2, make sure no stacking model inside the plate. Use the pre-set CB21 parameter or set in custom with 10 min 50 degrees. After curing, make sure the model be placed 1-2 hrs for the most stable strength.
*You could skip this stage if you would like to cure after adding glaze.
Support Removal
After washing, remove the supports carefully. For small parts, you may use scissors to assist with the removal.
Griding
Carefully grind the areas with added supports using a small diamond grinding head to avoid
damaging the occlusal surface. After checking the occlusion of the All-on-X model, place it on the abutment to test the fit.
If the fit is too tight or too loose, adjust the design accordingly and repeat the process.
Gingiva Mimic
Use an appropriate amount of bonding liquid and self-cure acrylic resin to replicate the gingiva color on the All-on-X model.
Polishing with Nitrogen Gas Curing Box
After grinding, clean the teeth surface with clean IPA and a soft brush to remove dust, then use a compressed air to dry the surface. Apply a thin, even layer of ceramic pen to the All-on-X model, ensuring that no resin drips from the model, as this could affect the fitting.
NOTE:Too much resin may cause opposite resin on surface.
Place in the FabCure N2 and choose “Aesthetical Mode” for a 30s nitrogen curing.
Cleaning and Disinfection
Use an ultrasonic machine with IPA (≥75%) for less than 1 minute to clean the model surface, then soak the model in IPA for 10-15 minutes. After soaking, rinse the model under clean water.
*All the above procedure meets the policy under biocompatibility
