Abstract :

 Aim: Aim of the study was to digitally evaluate accuracy of reattaching fractured dental

stone (type III gypsum product) teeth to dental casts using cyanoacrylate adhesive.

Methods and Material: Ten mandibular dental stone casts were obtained using mandibular

dentulous rubber cast mold. Dental stone casts were modified to make four teeth (one incisor,

one canine, and two premolars) fracture prone by making them isolated and elongated. Modified

gypsum casts were scanned using 3D scanner (Ceramill Map400, Amann Girrbach AG). Three

out of four fracture prone teeth were fractured and reattached with cyanoacrylate. One unfractured premolar on each dental cast was used as control. After reattachment casts were

again scanned in same position using 3D scanner. Scanned data was used to digitally evaluate

dimensional changes in reattached gypsum teeth using 3D analysis software (PolyWorks,

InnvoMetric).

Results: Mean displacement in X (mesiodistal), Y (occlussogingival), and Z (faciolingual) plane

for measured points (n=120 points) on reattached teeth were 0.0268 mm (SD 0.0082), 0.0482

mm (SD 0.0113), and 0.0047 mm (SD 0.0020) respectively. Mean displacement in 3D for

measured points on reattached teeth calculated as surface distance based on XYZ displacement

was 0.0615 mm (SD 0.0162). Two–way ANOVA test revealed no stastically significant difference of dimensional change after reattachment of teeth with different morphology.

Conclusions: In the context of present study, it can be concluded that reattaching cleanly

fractured dental stone teeth (type III gypsum product) with cyanoacrylate adhesive results in

clinically insignificant dimensional change.
