Summary

Introduction:

One major complaint frequently voiced by complete denture wearers is denture retention. Conventional denture disadvantage is heat-curing resin deformation. In addition, the pack and press technique that is still more common, residual stresses that occur at the time of packing are released when the material is removed from the flask, causing the resin to shrink, and this shrinkage is cited as a cause of poor fit of the denture base, In the field of prosthetic dentistry, the ability of additive manufacturing to fabricate prosthetic devices based on CAD data influences the overall quality, the mechanical properties of printed parts, the total cost and the manufacturing time. The milling process wastes large quantities of denture base material, and more recent three-dimensional (3D) prototyping promises a more sustainable additive approach by using less denture resin. However, no clinical reports have been published regarding the accuracy of the mucosal surface or denture retention for denture fabricated using conventional techniques compared to those fabricated using additive manufacturing.

Aim of the study:

Investigate the effect of two techniques of complete denture manufacturing (conventional and 3D printed) on denture retention, trueness (accuracy), and satisfaction.

Methodology:

Twenty patients will be selected from the outpatient clinic and will be divided into 2 groups, group A for conventional dentures and group B for 3D printed dentures, retention for the two groups will be measured at 0,1 and 3 months, and patient satisfaction will be recorded, and accuracy of the denture base will be measured on the software. The results will be tabulated and statistically analyzed using the SPSS program.
