Surgical guides for dentistry: osteotomy and implants sites preparation using open software and freeware for virtual planning and guides project and production – Presented by Sandro Montecchiani, owner of private dental practice, at the 3D Medical Conference, on January 30-31, 2019, MECC Maastricht, The Netherlands.
3D dental imaging and 3D printing have changed dentists’ job: now we can plan virtually the prosthesis, the implants positioning, we can project guides and models, and finally 3D print such devices, everything starting from a CBCT exam and an intraoral optical scan.
This is a fantastic procedure in particular for implants surgery, because we can be extremely precise and easily avoid any damage to anatomical structures to be respected. For complex cases, where we need to plan a full arch restauration, we could need to perform a bone surface levelling, but doing this by freehand sometimes can’t be as precise as we might need.

Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven at the 3D Medical Printing Conference, which will take place on 30-31 January 2019 at MECC Maastricht, The Netherlands.
Dental implants are an important elective option for the replacement of a missing tooth or teeth. The abutment acts as an interface between the implant and artificial tooth/teeth. A novel dental implant abutment, that provides a simple, efficient and inexpensive alternative for tooth fabrication, has been developed, patented and termed Tempcap.
The initial (traditional) prototype was fabricated by laser welding components but resulted in a weak structure with excessive variability in design. Manufacturing through conventional machining proved too costly and complicated. Additive manufacturing was investigated as an alternative to fabrication. The prototype was digitized and refined through CAD and initially printed in Duraform 316L stainless steel. The prototypes were qualitatively assessed for functionality by implant threading and successful simulated fabrication of an artificial tooth in a laboratory setting.
Based on the final optimized design, Tempcaps were 3D printed in dental-grade Titanium (Ti-6Al-4V) (ADEISS, London, ON). Complimentary to the 3D printing process, all Tempcaps underwent post-processing, which included final thread tapping for pronounced thread geometries, heat treatment for relieving thermal stresses and strengthening, and bead blasting for a smoother finish.
The final research objectives are: (1) to compare the maximum torques experienced during insertion of conventional and 3D printed Tempcaps into dental implants and (2) to assess the mechanical strength of the retentive pin projections under compression.
Results will be obtained this summer. The research will provide the necessary results required to verify and validate the 3D printed Tempcap for a clinical assessment. Continue reading “Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven”
