“…A large amount of material will cause inherent stresses to be built within the material with resultant strain. The use of resin to reinforce the impression material may cause discomfort for the patient due to the exothermic heat of polymerization [8].…”

The conventional methods of impression making for maxillofacial defects are cumbersome and time consuming for both patient and operator. This study focuses upon standardizing and simplifying the impression making methodology for auricular prosthesis with the help of prefabricated stock trays for auricular region. The stock trays were designed on positive replicas of anatomical structures, broadly divided into long and narrow, short and broad and long and broad ear. For each stock tray, impressions of auricle, of patients of different morphology were made with plastic funnels of different shape and size ensuring at least 6 mm of space between the anatomical part and inner surface of funnel and master cast was obtained. Subsequent adaptation of wax was done and fabrications of stock stainless steel trays were done. A standardized stock tray for making of auricular impressions was developed. From this innovative technical procedure it is possible to get an accurate impression of auricular defects now by the use of prefabricated stock trays rather than the cumbersome conventional method.

“…Reproducibility of the auricular impression apart from impression material depends on various factors but primarily on patient position during impression making. Although the CIT is less technique sensitive and less time consuming, having the patient lie on one side can cause distortion of the soft tissue contours from the weight of the impression material against the skin [6]. Thus, the success depends on the use of a proper impression technique, apart from the maxillofacial prosthetic skill and artistry [7].…”

Abstract-The purpose of this article was to compare the accuracy of a new impression technique, the triple-layer impression technique (TLIT), with the conventional impression technique (CIT) to fabricate an auricular prosthesis. Fifteen male subjects (aged 22-45 yr) were selected. Ten markings were made on the subject's ear (super aurale [sa], sub aurale [sba], pre aurale [pra], post aurale [poa], A, A1, B, B1, C, and C1) and five measurements (sa-sba, pra-poa, A-A1, B-B1, and C-C1) were made. Custom-made trays were used to record impression in CIT and TLIT. Impressions were made using alginate, and models were cast with type IV gypsum product. Markings were transferred on the cast. Measurements were rechecked on the models. Distribution analysis of difference in measurements between the two impression techniques and the subject's actual values was evaluated. Sign test was used to analyze the statistical significance. Statistically significant differences were found in measurements A-A1, B-B1, and C-C1 between the two techniques when compared with the subject's actual dimensions (p < 0.01). TLIT was found to produce accurate models when compared with CIT. The TLIT used in the study was cost effective, less technique sensitive, and tailor made to reduce chairside orientation time during wax try-in appointments for rehabilitating patients, especially those with unilateral auricular defects.

“…Preoperative planning with the maxillofacial surgeon and the prosthodontist is vital for optimal outcomes: today, the virtual planning of the craniofacial implant insertion and the rapid prototyping of the surgical template requires the collaboration of the CAD-CAM specialist engineer. Many articles have described computerized technology without considering this important step and the procedure required for the correct positioning of craniofacial implants within the external volume of an ear or nasal prosthesis (Nusinov & Gay 1980;Mankovich et al 1986;Girod et al 1995;Beumer et al 1998;Coward et al 1999;Penkner et al 1999;Runte et al 2002;Cheah et al 2003aCheah et al , 2003bHecker 2003;Kubon & Anderson 2003;Lemon et al 2003;Reitemeier et al 2004;Mardini et al 2005).…”
