Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven

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.


What drives you?
Excitement: the opportunity to improve the dental experience for the clinician and patient with a minimal environmental impact

What are the three things you would take with you on a deserted island?
sailboat, water purifier, map

What emerging technologies/trends do you see as having the greatest potential in the short and long run?
short term: 3D printed everything, connected everything; long term: modulated smart devices and technologies

What kind of impact do you expect them to have?
Although 3D printing will provide increased efficiency, accessibility and reduced costs, materials still require further development. A jump in 3D printing will require proper management of expired materials to prevent an environmental catastrophe. Increased connectivity will require strict privacy regulations and protocols. Modulated smart devices and technologies would limit material use and maximize utility.

What are the barriers that might stand in the way?
Cost, technological limitations, environmental issues and doubters.

What do you hope people to learn from your presentation?
The novel dental implant abutment developed through digital dentistry and additive manufacturing provides a LEAN approach for both the clinical aspect of dentistry and the production of the component. This approach is a win-win-win alternative, as it reduces time, costs, waste, environmental impact and barriers to patient care.
