Purpose: To evaluate the challenges of the direct filling technique, the use of dental chairside CAD/CAM milling, the use of 3D printing, and the attitudes toward 3D printing-based applications for restorative treatments among Finnish dentists.
Materials and Methods: An electronic questionnaire was sent to 3,777 Finnish dentists. Background information, challenges linked to the direct filling technique, use of dental chairside CAD/CAM milling, use of 3D printing, and attitudes toward 3D printing-based applications in restorative dentistry were asked in the questionnaire with multiple-choice questions. The number of replies was 760, and the response rate was 20.1%.
Results: Poor survival rates and moisture sensitivity were the main reported challenges associated with the direct filling technique. Use of chairside CAD/CAM milling was reported by 271 (35.7%) respondents. Use of 3D printing technique was reported by 54 (7.1%) respondents. Most respondents answered that they would consider using 3D printing for manufacturing tooth fillings in the future.
Conclusion: If dental chairside CAD/CAM technology can provide a solution for manufacturing long-lasting indirect restorations with good esthetic properties and an effective cost-benefit ratio, the wider use of chairside CAD/CAM systems might be indicated, especially in the public sector. New 3D printing- based applications used for restorative treatments are attracting interest among Finnish dentists, but also indicate a need for further development of 3D printing techniques for cost-effective restorative treatment.
