This procedure is easy to use and is cost-effective because it uses equipment that exist in any office or institution. The material used, transparency film for use with plain paper copier, is less expensive than either photographic slide film or normal slide films. Moreover, the transparency sheet can be used again for photocopying until the sheet is fully used up. There is no added cost of development of film, or is it necessary to wait for the whole roll of film to be used before the label can be retrieved and used. The background of the label is clear and only the black images of the characters of the label can be clearly seen. The effect of the transparency film, photocopy ink, and adhesive glue is not known. But no adverse effects have been noted. Microlabels have advantages over conventional labels with characters in font size 8 to 12, because more information, such as the full name of the patient, sex, country of origin, and national identification number can be incorporated. With more detailed information, quick identification of a deceased person can be made. Microlabels with a clear background will have minimal esthetic impact on the patient. The disadvantages of the technique is that it may not withstand a fire. In situations where the deceased body is badly burned, the denture and its identification strip may be burned, too. However, this risk can be minimized by placing the strip in the most posterior part of the denture-palatal in the maxillary denture and distal lingual in the mandibular denture. For testing of durability, dentures with the labels were placed in water for up to 4 months. The labels showed no sign of fading or deterioration.

An alternative procedure for discrimination of contacts in centric occlusion and lateral excursion was introduced for eliminating premature contacts in lateral excursion without the alteration of other intercuspations. This procedure involves the application of red paper for the evaluation of lateral excursive contacts and blue paper for centric occlusion holding contacts to provide improved visibility of occlusal contacts.

Accurate and repeatable methods for recording tooth contacts are required for the clinical management of problems related to occlusion. A thorough understanding of the materials and procedures used in these methods is important to achieve desirable results in the treatment of such problems. This study compared three occlusal examination methods to determine the influence of materials and procedures on the number of tooth contacts recorded. Tooth contacts were analyzed at two lateral mandibular positions with each method. It was found that the method that uses black silicone recorded the highest number of tooth contacts. Thus the most frequent type of occlusal pattern observed was full-balanced occlusion. This study suggested that the disparities of results reported in literature on occlusal contact patterns could be the result of the different materials and methods used for occlusal registration.

A technique is described for ☐ing irreversible hydrocolloid impressions by using the paper sheets that separate ☐ing wax strips.
