Abstract

The making of removable denture is performed by a dental laboratory. To facilitate the identification, according to Kennedy classification, classes are divided onto groups, the Kennedy class I, II, III and IV. To suit with the needs of the dental laboratory tasks commonly done, priority are necessary for common cases and should to be taught to students of Dental Health Technology Diploma. In Surabaya, research of various cases of removable partial denture with the various Kennedy classifications has never been done before. This study was to analyze the pattern of service for the removable partial denture manufacture in dental laboratory at Surabaya (2011 – 2013). The research is an observatory analytic. The population is all dental laboratories located around the campus of the Faculty of Dentistry Airlangga University Surabaya. The sample was the whole population is willing to become respondents. Sampling by total sampling. The method of collecting data using secondary data from a dental laboratory in Surabaya from 2011 until 2013. The note is cases removable denture according to the classification of Kennedy that Kennedy Class I, II, III and IV. Also of note kinds of materials used to make the denture base that is heat cured acrylic resins, thermoplastic resins and metals coherent. The data is a compilation table charting the frequency until needed, then analyzed using cross tabulation. Mostly denture type is flexible type and the least is metal framework. Most cases by classification Kennedy is followed by class II class III and class II and more recently is the fourth. In conclusion, in 2011 and 2013 the manufacture of removable partial dentures according to the classification of Kennedy Class III is the most common in both the upper arch and lower jaw, followed by Class II, Class I and Class IV. In 2012 which is the highest grade III followed by class II, class IV and class I. The denture type most used is a flexible denture, followed acrylic denture and the last is the metal framework.

Abstract

One of the stages of manufacture of denture metal framework that is sandblasting, ie cleaning the remnants of investment material after metal casting process and remnants of metal oxide on the surface. After fitting in the master model, then the metal framework dentures do sandblasting again until smooth before elektropolishing. The tools used are sandblaster, material Al2O3 (aluminum oxide) size of 250 lm. The time it takes about 1 minute, but the time of 1 minute when applied to student practicum D3 is still not clean and there are still remnants of planting material castings and metal oxide on the surface of the Co-Cr. Objective: To determine the effect of time on pembutan teeth iruan sandblasting the metal frame of the metal surface roughness Co-Cr. This study is experimental laboratories. A sample of tablet shape with a diameter of 7mm, 2mm thick metal. Number of samples 24 tablets were divided into 4 groups each group consisting of six tablet samples. Distribution of the sample group of the study are as follows; Group 1; Sandblasting metal surfaces with 250 µm Al2O3 time of 1 minute, Group 2; Sandblasting metal surfaces with Al2O3 250 ?m 2 minutes, Group 3; Sandblasting metal surfaces with Al2O3 250 µm 3 minutes, Group 4; the group did not do sandblasting. Data were analyzed with ANOVA statistical analysis of the lane with 0:05 significance level. If there is a significant difference between groups duiji with HSD test. There were significant differences in surface roughness Co-Cr metal between the control group without sprayed with the spray group at 1 minute, 2 minutes and 3 minutes. In conclusion, the surface of a metal frame that is not done sandblasting coarser than done sandblasting. The longer the time sandblasting increasingly produce a smooth surface of a metal frame. Sandblasting is perfectly need sufficient time is 2-3 minutes.
