Traditionally, customising a titanium mesh for alveolar height augmentation involves a lengthy process of 3D metal printing. This requires extended communication between the surgeon and the designer, and a delivery time of 6-9 weeks. Osteopore’s Digital Surgical Dentistry (DSD) system aims to provide clinicians with the flexibility to customise dental scaffolds chair-side during surgery, all within the same day as the patient’s visit.
Singaporean dental 3D printing company Star3D Materials Development Company, collaborates with Osteopore International as both homegrown companies seek to advance digital dentistry solutions. Together, Osteopore and Star3D aim to reduce the wait time to treat jawbone resorption with factory customised titanium mesh for alveolar height augmentation from 6-9 weeks to a same-day treatment. Leveraging Osteopore’s expertise in regenerative biomimetic scaffolds, the collaboration introduces the DSD System, enhancing surgical procedures and optimising patient outcomes.
The DSD system encompasses the 3D3 Mini 2 printer, Osteomesh, and a water bath. This system solution is designed to follow a five-step process starting from printing of the patient’s model, to sterilising, shaping and trimming the Osteomesh, before trying it in and inserting the material into the patient.
Such outcomes are achieved in three key areas. First, surgical procedures are streamlined as pre-moulding of the Osteomesh allows for sameday treatments and reduces the operation time. Next, the precision in customisation minimises soft tissue disruption by avoiding several trials of inserting the mesh. Last, patient comfort is elevated as the DSD System reduces the duration of mouth opening.
3D3 Mini 2 printer
The 3D3 Mini 2 model SLA 3D printer is designed to develop precise patient models. Its specifications include a 4k resolution to achieve anatomical accuracy with clarity and a capability to print fine layers at 50μm per layer to capture intricate features precisely. Furthermore, the printer features a built-in light cure box for streamlined post-print curing, and a double guide rail system for steady performances.
Efficient speed settings provide a balance between speed and accuracy, and the printer can accommodate complex anatomies with a 90mm print height. It comes with a one-year warranty period, supports .STL files, and connects via LAN, wifi.
Moreover, the DSD System includes a post-curing station that complements the 3D3 Mini 2 printer. The station tailors curing times with intervals of 1min, ranging from 5-60mins. It also provides water and air curing methods to suit specific needs, with a wavelength of 405nm.
Preparation of Osteomesh
At the heart of the system lies the Osteomesh — a semi-flexible, bioresorbable mesh engineered to provide dimensional retention and graft material support. This innovation offers predictable shape and volume of regenerated bone tissue in guided bone regeneration. Its preparation follows three steps.
Sizing of defect: Select the suitable size of Osteomesh, remove from single wrap sterile packaging and place in dry sterile bowl.
Trimming: Using a pair of sterile surgical scissors, trim Osteomesh to the desired shape. It is recommended to completely remove the borders of the mesh.
Moulding: Warm up sterile saline to the appropriate temperature in the water bath for moulding.
Immerse Osteomesh for approximately 10secs to make it more malleable. Using the sterile model as a guide, contour and form the Osteomesh in the desired vertical and horizontal measurements for approximately 5secs. Remove Osteomesh from the warm saline while holding it in its new shape for another 10secs. Repeat step until desired shape is formed. Refer to the table for the appropriate temperature.
