  • Objectives; The purpose of the present study is to investigate the difference in levels of satisfaction between dental laboratory owners and employed dental technicians in the area of dental laboratory management. Methods; The samples of seventy-one dental laboratory owners and sixty-six employed dental technicians were selected in a blinded and random manner. Data was collected through self-administered questionnaires and analyzed using average values, the t-test and multiple regression. Results; 1) There was no significant difference in the average values of general satisfaction levels related to dental laboratory management between dental lab owners and employees. 2) The average values of satisfaction levels in 11 specific items scored 'above average' among dental lab owners and 'average' among employees. 3) The average values of satisfaction levels in 10 specific items except for 'trust and respect' showed a significant difference between dental lab owners and employees. 4) Important factors which influenced the satisfaction level of dental lab owners were 'trust and respect' and 'improvement of employee's benefits'. In the employees group, 'trust and respect', 'improvement of employee's benefits' and 'technical information support' were important factors. Conclusion; The present study revealed that dental laboratory owners and employees have some gaps between the viewpoints in dental laboratory management. This suggests the necessity to improve management in a transparent and economical way. However this study has some limitation in that the sample size was not massive enough.

  • Self-leadership means a person's ability to make his thought or behavior in a right way by controlling it himself. Strategies of the same leadership can be largely categorized into three, behavior focused, natural reward and constructive thought strategies. In this study, the foresaid styles of self-leadership strategy are discussed from the perspective of dental lab laboratories' business environment of Gyeongnam region. And accordingly, this researcher examined such strategy styles that dental lab managers, chief technicians and assistant technicians usually have. Results of the study can be summarized as follows. First, out of the self-leadership strategy styles, most remarkably found among the professional of dental technology was constructive thought strategy, followed by behavior-focused and natural reward strategies in order. In general, therefore, the professionals strongly tend to make their thoughts that can a positive effect on their work performance or in a constructive way. In other words, professional dental technicians are more likely to make efforts to persuade or persuade themselves to change their own unreasonable confidence or negative process in more positive way. Second, the extent to which constructive thought strategy is perceived was not different among dental lab managers, chief technicians and assistant technicians. While, behavior-focused and natural reward strategies were found most strongly perceived by dental lab managers, followed by chief and assistant technicians in order. This may be attributed to the fact that the higher professional dental technicians are in position, the higher they are in self-leadership, or in the ability to overcome crises by themselves and make their thought or behavior in a right way. Dental lab managers usually have lots of experiences in relation to behavior-focused or natural reward strategy. Therefore, they are very strongly capable of controlling themselves in order to overcome crises or make their thought or behavior in a right way. In contrast, assistant technicians are still having lots of trials and errors because they are less experienced and skilled. This suggests that chief technicians should make themselves fully capable as a medium that connects between dental lab managers and assistant technicians.

  • The purpose of this study is to investigate relations among job-related attributes of dental technicians. Findings of the study can be summarized as follows. Differences in four job-related attributes among dental technicians in accordance with their titles were investigated to find that dental lab managers were higher in job satisfaction than chief and assistant technicians of the lab. Dental lab managers were given the best work climate, followed by chief technicians of hospital, those of dental lab and assistant technicians. Job competence was highest in part of the managers, followed by chief assistants of hospital, those of dental lab and assistant technicians. But work facilities that were being used by dental technicians were not significantly different in quality in accordance with their titles. Assistant technicians were lower in job satisfaction, given work climate and job competence than managers and chief technicians of both hospital and dental lab. Under same work conditions, female dental technicians were higher in job satisfaction than male ones. Dental technicians' job satisfaction were most affected by work climate, followed by job competence and the quality of work facilities in order. In other words, job satisfaction was higher when work climate was better, job competence was higher or when work facilities were better. Job satisfaction was generally lower in part of male dental technicians than female ones. Considering the fact that job satisfaction is most influenced by work climate, more careful attention should be paid to assistant technicians who while on duty, usually have not so good relationship with seniors or colleagues. Those technicians also usually have few or no opportunity of obtaining latest knowledge or skills, so they should be allowed time for seminars or lectures in which such knowledge or skills are educated. It is also important to raise assistant technicians' pride about their job by empowering them by authorization or giving more remuneration or other rewards for their improved job competence.

  • Purpose: The purpose of this study was to evaluate the validity of digital models fabricated by dental scannable stone. Methods: Twenty same cases of stone models(maxillary full arch) were manufactured. Intercanine distance, intermolar distance, two dental arch lengths(right, left), two diagonal of dental arch lengths(right, left) were measured for comparison. Each of ten stone models were measured by digital vernier calipers and scanned by dental scanner. Ten digital models were measured by CAD program. The mean(SDs) values were compared by a Mann-Whitney U test(${\alpha}$=0.05). Results: No statistically significant differences between the two groups were found at intermolar distance, dental arch length(right)(p>0.05). However, intercanine distance, dental arch length(left) and two diagonal of dental arch lengths(right, left) were statistically significant(p<0.05). Conclusion: Stone models fabricated by dental scannable stone showed larger than digital models.

  • Objectives; The purpose of the present study is to investigate workplace satisfaction level of dental technicians and the differences between that of dental lab owner's and that of employed dental technicians, who are working in dental laboratories. Methods; Samples were comprised of 137 dental technicians working in dental laboratories. Data were collected through self-administered questionnaires and analyzed to frequency distribution, correlation, t-test and multiple regression analysis. Results; 1) Dental technicians generally are 'somewhat or a bit satisfied' with their workplace situations, regardless of position, sex, and individual career. 2) Mean values of 4 items out of 11 work situation factors of employed dental technicians were significantly lower than those of lab owner's. The 4 items are the openness of management, working environment, pay, and policy in promotion and raise. They would be sources of dissatisfaction and conflict. 3) Level of satisfaction was significantly correlated with 2 subordinate variables, i.e. working conditions and administration policy. There is a tendency that administration policy is a bit more important for lab owners, while working conditions are a bit more important for employed dental technicians. Conclusion; The employer-employee relationship of dental technicians seems to be sound, as no signs of troublesome problem is detected. But the discrepancy revealed in the above results is telling that there certainly exist some disagreement in the viewpoints of the two groups. It is necessary for the dental technicians to find ways to deal with the possible triggers of discord and discontent.

  • A new kind of 'All Ceramic Crown' could be manufactured by making improvements in the manufacturing technique for the current 'All Ceramic Crown' which does not use a special ceramic but rather a general one as a substitute. If we use the manufacturing technique for the 'All Ceramic Crown', metal coping and core are not produced. The effects of the new manufacturing technique for the 'All Ceramic Crown' are as follows: First. We do not need to use new material or special machinery or tools. Second. We can use general machinery and tools. Third. Using the basic 'All Ceramic Technique', we anticipate improvement in learning in our students. Forth. We can save effort, materials and time. Fifth. The technique also has advantages for esthetic 'temporary crown'.

  • Purpose: The purpose of this study was to evaluate the repeatability of dental white light scanner. Methods: The impression(Zerosil, Dreve, Germany) were digitized in white light scanner(Identica, Medit, Korea) to create 3-dimensional surface-models. The distribution of the discrepancies between the number of points in the corresponding CRM models and the point clouds in the others were measured by a matching-software(PowerInspect 2012, Delcam Plc, UK). The discriptive statistics were used for statistical analysis(SPSS 20.0). Results: The measurement of repeatablity showed very good reliability. The mean(SD) discrepancy value on the white light scanner digital models was 8.7(0.67) ${\mu}m$, based on SD and absolute mean values. Conclusion: These in vitro studies showed that repeatability of dental white light scanner is high reliability. These results can be confirmed in further clinical studies.
