Abstract:

BACKGROUND: The pressure is fully on the gum because complete dentures lack supports from the teeth. Gum inflammation and metal allergies often occur because of gum wearing when patients chew. Doctors must test the adaptability of the material on dentures firstly before installing dentures for patients.
OBJECTIVE: To reconstruct three-dimensional model of dentures after running-in.
METHODS: The three-dimensional data of complete dentures following running-in were collected by laser scanners and other digital acquisition equipment. The pre-processing, such as noise reduction, data filtering, data reduction and repair of the missing data, were performed using reverse software, and wrapped into triangular surface. The model was reconstructed using Pro/E or other 3D design software.
RESULTS AND CONCLUSION: The three-dimensional data of complete dentures following running-in were collected by laser scanners, CT and other digital acquisition equipment. The pre-processing, such as noise reduction, data filtering, data reduction and repair of the missing data, were performed, and the curve model was extracted. The reconstruction of model was realized using the Pro/E or other 3D design software, which can provide digital information for making dentures. Copies of dentures can be obtained by rapid manufacturing. Complete dentures after running-in save time, reduce doctors’ labor intensity, decrease the risk for allergy to materials, shorten running-in time between patients and dentures, and reduce patient’s suffering.
