A new dental support system significantly improves tooth preparation skills for students. Training with this system resulted in better axial wall convergence and parallelism compared to traditional methods.

Area of Science:

  • Dental Education
  • Biomechanical Engineering in Dentistry

Background:

  • Tooth preparation is a fundamental dental skill that presents a learning challenge for students.
  • Developing effective training methods is crucial for dental education.

Purpose of the Study:

  • To evaluate the educational efficiency of a novel tooth preparation support system.
  • To compare the learning outcomes of dental students using the support system versus freehand preparation.

Main Methods:

  • A new tooth preparation support system with a parallel link mechanism was developed.
  • Dental students without prior clinical experience were divided into two groups: one using the support system and one using freehand preparation.
  • Participants prepared axial walls on maxillary premolars and molars in a phantom manikin, with convergence angles and inter-axial parallelisms evaluated.

Main Results:

  • Training with the support system yielded significantly lower convergence angles and improved parallelisms compared to freehand training.
  • Even after subsequent freehand practice, students trained with the support system demonstrated superior preparation quality.

Conclusions:

  • The developed tooth preparation support system enhances dental students' competency in achieving precise axial wall preparation.
  • This system offers a valuable addition to practical dental training programs for improving student skill acquisition.
