Evaluation of accuracy of complete-arch multiple-unit abutment-level dental implant impressions using different impression and splinting materials.

Purpose: This in vitro study evaluated the accuracy of multiple-unit dental implant casts obtained from splinted or nonsplinted direct impression techniques using various splinting materials by comparing the casts to the reference models. The effect of two different impression materials on the accuracy of the implant casts was also evaluated for abutment-level impressions. Materials and Methods: A reference model with six internal-connection implant replicas placed in the completely edentulous mandibular arch and connected to multi-base abutments was fabricated from heat-curing acrylic resin. Forty impressions of the reference model were made, 20 each with polyether (PE) and polyvinylsiloxane (PVS) impression materials using the open tray technique. The PE and PVS groups were further subdivided into four subgroups of five each on the bases of splinting type: no splinting, bite registration PE, bite registration addition silicone, or autopolymerizing acrylic resin. The positional accuracy of the implant replica heads was measured on the poured casts using a coordinate measuring machine to assess linear differences in interimplant distances in all three axes. The collected data (linear and three-dimensional [3D] displacement values) were compared with the measurements calculated on the reference resin model and analyzed with nonparametric tests (Kruskal-Wallis and Mann-Whitney). Results: No significant differences were found between the various splinting groups for both PE and PVS impression materials in terms of linear and 3D distortions. However, small but significant differences were found between the two impression materials (PVS, 91 mu m; PE, 103 mu m) in terms of 3D discrepancies, irrespective of the splinting technique employed. Conclusions: Casts obtained from both impression materials exhibited differences from the reference model. The impression material influenced impression inaccuracy more than the splinting material for multiple-unit abutment-level impressions.Article Link : http://www.ncbi.nlm.nih.gov/pubmed/2427891

Menciptakan Good and Clean Government Berbasis Syariah Islamiyah Dalam Tatakelola Pemerintahan Republik Indonesia

Terciptanya sebuah pemerintahan yang bersih dan berwibawamerupakan hal yang sangatlah urgen. Untuk menuju kepada pemerintahan yang baik dan bersih diperlukan pengelolaan berbagai bidang kehidupan seperti politik, hukum, ekonomi, sosial dan budaya secara lebih serius, transparan, dan terarah serta melibatkan semua komponen bangsa guna bersama-sama bangkit dari keterpurukan dan kehinaan di mata dunia Internasional.Dalam mewujudkan pemerintahan yang baik dan bersih, diperlukan berbagai cara, selain dengan menegakkan beberapa prinsip Good and Clean Governance, juga dengan menerapkan konsep syariah Islamiyah seperti nash Alquran dan hadis, kaedah fqhiyah dan maqhasid al Syariah. Dengan upaya ini, diharapkan dapat tertatanya birokrasi pemerintahan negara Republik Indonesia dengan selalu mengedepankan kepentingan masyarakat dengan meningkatkan kualitas pelayanan mutu bernegara yang lebih baik

Pemodelan Struktur Perlapisan Bawah Permukaan untuk Penentuan Bidang Gelincir pada Daerah Rawan Longsor. (Studi Kasus Ruas Jalan Nasional 005 Lakuan – Laulalang dan Ruas 006 Laulalang-Lingadan)

Characteristics of roads in Central Sulawesi at some point are an area of frequent landslides. The road segment in question, including the section 005 and section 006 which is a national road linking the province of Central Sulawesi and Gorontalo province. The link conditions that have often suffered landslides have disrupted access to transport and causing high transportation costs. This study aims to determine the geometry of the sliding plane at KM 509 and KM 513 using the method of geoelectric resistivity Wenner configuration with a path length measurement of 300 m and 5 m electrode spacing. The results of the study at two locations and modeling shows the layering structure resistivity value of which is at 100 Ωm - 300 Ωm and modeling results of 2-D geoelectric cross-section shows the sliding plane ground motion varies between 5 to 15 m. Value of resistance and sectional sliding obtained indicate that the location is vulnerable to landslides, and requires a comprehensive treatment to prevent landslides
