“…The use of optimal impression material enhances the inherent advantages of the material while avoiding the disadvantages. Utilizing a tray excludes the use of a reinforcing medium or the use of gauze pads [2] with all its accompanying disadvantages. The tray also permits the use of irreversible hydrocolloid impression material, a far more economical impression material vis-à-vis elastomeric material and the impression can be poured immediately, increasing the accuracy of the resultant cast.…”

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.

“…The scientific aspect requires an accurate impression for the development of an accurately fitting facial prosthesis [2]. Various maxillofacial impression techniques described so far have been based upon the materials available and the dexterity of the operator, making it more art than science.…”

Time may elapse between examination of marks inflicted on the body and comparison with a potential weapon. Two-dimensional photographs may be inadequate for effective comparison of a three-dimensional mark with a putative instrument. Taking a cast and producing a positive image results in a lasting three-dimensional record. This project aimed to develop and demonstrate the accuracy of an easy technique for production of long-lasting positive images (using plaster of Paris and dental alginate). Casts of facial features of embalmed cadavers were used to produce a positive image of the face (death mask). Measurements of distances between facial anatomical landmarks were compared with measurements of distances between the same landmarks on the death masks to assess accuracy of reproduction. There were no significant differences between cadaver and death mask in 6 of 9 measurements, indicating this technique has high accuracy with less mobile facial features, but produces deformation of pliable features.

“…There are a variety of techniques for making a facial moulage. The impression materials used for recording facial defects vary from impression plasters and hydrocolloids to elastomeric impression materials 9 . An ideal impression material should have the ability to record the defect, adjacent structures, and engageable undercuts with minimal distortion.…”

Loss of orbital content can cause functional impairment, disfigurement of the face, and psychological distress. Rehabilitation of an orbital defect is a complex task, and if reconstruction by plastic surgery is not possible or not desired by the patient, the defect can be rehabilitated by an orbital prosthesis. The prosthetic rehabilitation in such cases depends on the precisely retained, user-friendly removable maxillofacial prosthesis. Many times, making an impression of the orbital area with an accurate record of surface details can be a difficult procedure. The critical areas are making a facial moulage, mold preparation, and attaching the retention device, particularly when eyeglass frames are used. This case focuses on these hindrance factors. A simple basket was used for the impression tray to obtain the facial moulage. A putty mold was used, and attachment of the prosthesis to a retention device was accomplished with positional distance. This method proves to be an economical and simple way of making an orbital prosthesis.
