        Permite – A Classic, The Dental Advisor, Volume 15, 1998.<\/p>\n

        Permite was first released in 1976 in Australia as Permite. In 1979, it was released in a pre-encapsulated form in the USA and was provided in 3 sizes and 3 alloy\/mercury ratios: minimum, normal and extra. It was also made available as powder and tablets in fast and regular set. Feedback from dentists in the USA and Australia resulted in reformulation in the early 1980’s. Concurrent with these changes, the terms minimal, normal and extra ratios were changed to fast, regular and slow set. Additional input from dentists resulted in the release of Permite ECT (extended carving time) in 1985.<\/p>\n

        Requests for a larger amalgam mass for large restorations led to the 1993 introduction of Permite in 5 spill capsules containing 2.3g of amalgam. This large capsule has been well received. At the request of a dental school in the USA, Permite SC (slow carving) was developed for use in training dental schools. Having withstood the test of time and become popular with many dentists, Permite is now available in 1-, 2-, 3- and 5-spill sizes in fast, regular, slow, ECT and SC setting times. Bulk powder and tablets are also still available in fast and regular set. Permite has only recently become available in the Direct Placement (DP) amalgam capsules, in which the amalgam is triturated and then dispensed directly into the cavity.<\/p>\n

        The ease of use, excellent properties, and convenient packaging, combined with a long track record of clinical success, resulted in Permite receiving one of the highest clinical ratings ever given to a dental amalgam by our consultants – a 98% rating.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

        Using an in vitro air pressure test, the authors found a wide variation in the microleakage characteristics of amalgam restorations made from 33 recently manufactured precapsulated alloys. Spherical particle alloys as a group exhibited the highest microleakage values. When the authors changed the mercury \/ alloy ratios to produce 1 percent more mercury in the capsules by weight, microleakage decreased significantly. Because extensive microleakage of amalgam restorations has been related to increased post-operative sensitivity, the authors suggest that practitioners should be alert to this potential problem.<\/p>\n

        In this study to provide updated information to manufacturers and practitioners, Permite demonstrated the lowest value of microleakage of all the 33 alloys tested. This result is consistent with other results documented.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

        Permite, The Dental Advisor, Vol. 5, No. 2, March\/April 1995.<\/p>\n

        Permite is an excellent dispersed phase type amalgam that can be used for a full range of restorative procedures. It received a 98% approval rating.<\/p>\n

        Permite is a dispersed phase type amalgam available in 1-, 2-, 3- and 5-spill capsules. Permite has a slight expansion at 24 hours after placement. Its compressive and tensile strengths and creep compare favorably to premium alloys. Twenty-five consultants in the United States and Brazil used Permite in over 1000 cases.<\/p>\n

        Permite received a 98% approval rating for consistency of mix, ease of loading, placement in preparations, condensability, burnishability, quality of interproximal contact, carvability, and setting characteristics. High-, medium- and low-energy amalgamators provided good mixes. The working and setting times allowed large restorations to be condensed and carved without difficulty. The resulting restorations were smooth and had excellent margin adaptation, especially after burnishing. All consultants said they would recommend Permite to their colleagues.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

        It can be concluded from our study that Permite, a modified conventional amalgam is an acceptable posterior dental restorative material for periods up to 3\u00bd years.<\/p>\n

        The performance of Permite was assessed in a 3 year clinical study. The restorations were assessed by examination of the actual restoration and photographs of them. The report concluded that Permite is an acceptable posterior dental restorative.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]Request Full Copy<\/a>[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

        To evaluate the clinical handling characteristics and selected physical properties of Permite amalgam restorative material. The results of this evaluation will determine its suitability for use in federal dental service clinics. The Laboratory evaluation consisted of exterior amalgam capsule microscopic evaluation, mercury vapour readings during trituration, residual visible mercury retained in the capsules after trituration and microleakage.<\/p>\n

        Permite was rated as acceptable for use by the Federal Dental Services with the following comments:<\/p>\n
