Implementation Challenges of 3D Printing in Prosthodontics: A Ranking-Type Delphi

Area of Science:

• Dentistry
• Materials Science
• Manufacturing Engineering

Background:

• 3D printing (additive manufacturing) offers potential for dental prosthetics due to reduced costs and enhanced benefits.
• Despite its promise, practical implementation of 3D printing in dental settings faces significant challenges.
• Understanding these obstacles is crucial for successful integration.

Purpose of the Study:

• To identify and rank the primary implementation challenges of 3D printing in dental practices.
• To provide insights for overcoming barriers to adoption.
• To inform strategies for integrating additive manufacturing in dentistry.

Main Methods:

• A ranking-type Delphi study was conducted.
• Surveys were administered to dentists, dental technicians, and 3D printing companies.
• Data was analyzed to prioritize implementation challenges.

Main Results:

• Lack of knowledge was identified as the most significant obstacle.
• High staff training effort and preference for conventional methods (e.g., milling) were ranked second and third.
• Investment costs, lack of manufacturing facilities, and print duration were ranked lower.

Conclusions:

• Education and training are paramount for the successful implementation of 3D printing in dental practices.
• Addressing the knowledge gap can accelerate the adoption of additive manufacturing.
• Internal production management and increased implementation speed are achievable through enhanced professional education.
