Abstract

Aim: This study aimed to compare digitally fabricated auricular prostheses to conventional prostheses, regarding adaptation to defect site in patients with auricular defects.

Subjects and methods: Fifteen patients were recruited for auricular prosthetic reconstruction. Endosseous implants were placed, then patients were assigned into two groups. In control group, ear models were processed on stone cast obtained from conventional impression. In intervention group, computed tomography and optical scanning were combined to obtain a virtual model with digital analogues over which ear models were designed and printed. Ear models of both groups were seated, and adaptation was measured on the patient using silicon replica technique and evaluated using a digital microscope. Independent sample t-test was used to compare between two groups. The significance level was set at P ≤ 0.05.

Results: There was no significant difference between the two groups. Measurements were taken for overall gap, marginal gap, gap close and distant to the implants with mean values 1.17,0.85, 0.98, 1.21 for control group and 1.22, 0.81, 0.98, 1.12 for intervention group respectively, (p>0.05). In comparing areas distant and close to the implants, mean values were 1.16 and 0.98 respectively, p=0.154.

Conclusion: Auricular prostheses fabricated conventionally or digitally have comparable adaptational accuracy
