Effect of the communication between dentist and dental technician on denture fabrication success
Objective To investigate the effect of the communication between dentist and dental technician on dentures fabrication.Methods A total of 6606 denture fabrication forms selected randomly from a dental laboratory in Nanjing,Shanghai and Guangdong were divided into four types I,II,III,and IV,according to the integrity of fabrication information and the reworking rate was calculated.Results The reworking rate of each type was 5% in I,8% in II,6% in III and 15% in IV,which was significantly different among all groups.The reworking rate of each kind of dental prostheses was 7% in PFM,7% in casting alloy crown,2% in post-core crown,5% in metal frame,4% in complete denture,4% in concealed denture and 5% in the others,which was not significantly different among all groups.Conclusion The integrity of the fabrication forms information is related to reworking rate.The type of dental prostheses does not influence reworking rate.
