This study was attempted in order to look into 'Assist work' as to Implant system which dental hygienists perform in a clinical field. Subjects of this research were 362 dental hygienists who work at general hospital, University hospital, dental hospital, and dental clinics located in Seoul, Kyeong-gi, In-chon, and Jeon-buk area. As to research tool, we produced questionnaire which was comprised of the total 25 items regarding 3 of general features (age, career of dental hygienist, and personality), 6 of implant system assist work, 3 of Informed consent before surgery, 6 of preoperative preparation and maintenance related business, and 7 items related to postoperative maintenance. By using SPSS program, collected data was analyzed. Results of analysis in this study were as follow; 1. As to implant related education, dental hygienists' experience of education was high as 77.7%, and the people who is needed more education was 86.3%. Consequently, dental hygienists' concern about the implant related education was very high. 2. It was observed that most of informed consent making approvement by announcement to the surgical operation was made by dental hygienist before implant as 95%. 3. Over 80% of dental hygienists performed acquisition of cleanliness technology, motivation, back up articles preparation, treatment area arrangement, and etc. which we can check by preoperative maintenance items. In particular, response about the motivation was very high as more than 90%. 4. When performing an operation, in the case of disinfecting finger was low for 53.9% and the method was mainly washing with drug solution, and gown sterilization was performed only in 52.2%. Therefore education regarding disinfection was urgently needed. 5. Significance of education could be known that answers of hygienists experienced education appeared highly in items of maintenance method and there was statistically significant difference(p<0.05). 6. In case that assist work were 21cases or greater, agitation measurement was the most many performed in 68.9% and difference was showed up significantly(p<0.001). 7. Evaluation about periodontal tissue was high in dental hygienists who had experienced education and also there was statistically significant difference. In conclusion, assist work of dental hygienists was very comprehensive when implant surgery was performed, and all of items excluding hand disinfection or gown disinfection were highly showed up in most of hygienists. However, since there is the limit that we didn't investigate the quality of performing contents. It is considered that further study regarding the content has to be progressed for supporting this result in the future.

Although first generation total ankle replacement (TAR) had high failure rates, recent investigations have reported good results of the newer generations of TAR due to advances in implant designs and techniques. Patient selection is critical to performing TAR to obtain promising outcomes and to decrease complication rate. As the current concepts of correcting the accompanying deformity have been established, TAR in moderate to severe varus deformity of the ankle result in favorable outcomes and indications for TAR are expanding. Correction of deformity and hindfoot fusion should be performed in conjunction with TAR if needed. If radiolucency around components or osteolysis is progressive during follow-up, CT should be carried out as a confirmative diagnostic method. TAR is an effective treatment modality alternative to ankle fusion. However, we should recognize that TAR is a demanding procedure, which requires accurate techniques, enough experience, and preoperative plan for a concomitant deformity.

The dilemma regarding the management of condylar fractures generally revolves around the surgical approach, implant design, and the surgeon's experience. Zide and Kent's guidelines streamlined the decision making process for condylar fractures. However, there exists no standardized protocol for reduction and fixation of condylar fractures. Here, we have described a detailed and stepwise protocol, common to any surgical approach, that would lead to predictable, reproducible, and repeatable results in every surgeon's hands.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently described form of T-cell non-Hodgkin lymphoma now formally recognized by the World Health Organization classification of lymphoid neoplasms. The aim of this paper is to report the first case of BIA-ALCL diagnosed in a pregnant patient. It is well known that BIA-ALCL appears as an indolent lymphoma with a good prognosis when diag-nosed at early stages and clinical guidelines for its management have been clearly published. Nevertheless, they lack a standardized approach for BIA-ALCL during pregnancy. With limited experience in our case, treatment has been safely postponed after term without affecting patient's overall prognosis and without fetal complication. The fact that the disease was diagnosed at an early stage (stage I) undoubtedly influenced the course of treatment. A multidisciplinary approach weighing the risks and benefits of treatment is of paramount importance in order to ensure the best possible outcome for both the mother and her child and clinical update guidelines should be issued.

Purpose: The purposes of this study were to develop a workstation computer that allowed intraoperative touchless control of diagnostic and surgical images by a surgeon, and to report the preliminary experience with the use of the system in a series of cases in which dental surgery was performed. Materials and Methods: A custom workstation with a new motion sensing input device (Leap Motion) was set up in order to use a natural user interface (NUI) to manipulate the imaging software by hand gestures. The system allowed intraoperative touchless control of the surgical images. Results: For the first time in the literature, an NUI system was used for a pilot study during 11 dental surgery procedures including tooth extractions, dental implant placements, and guided bone regeneration. No complications were reported. The system performed very well and was very useful. Conclusion: The proposed system fulfilled the objective of providing touchless access and control of the system of images and a three-dimensional surgical plan, thus allowing the maintenance of sterile conditions. The interaction between surgical staff, under sterile conditions, and computer equipment has been a key issue. The solution with an NUI with touchless control of the images seems to be closer to an ideal. The cost of the sensor system is quite low; this could facilitate its incorporation into the practice of routine dental surgery. This technology has enormous potential in dental surgery and other healthcare specialties.

Background: The objective of the present study was to specifically divide the various work performed by dental hygienists in clinical practice for legal amendments regarding problems associated with conflict between job roles and illegal delegation to establish key basic data for legislation and policy utilization for realization of legal scope of dental hygienists. Methods: The study used work reports drafted based on research methods in the "Second Job Analysis Report on Dental Hygienists" researched by the Korean Health Personnel Licensing Examination Institute in 2012 and "Opinions of Dentists on Actual and Legal Work of Dental Hygienists," a report published by the Korean Dental Hygienists Association. Of these, the study focused on conservation dentistry, pediatric dentistry, prosthodontics, oral and maxillofacial surgery, and dental implant treatment, which make up some of the fields covered by dental hygiene practice, to investigate and analyzed work performed by clinical experience. Results: Analysis of work actually performed in dental practice showed that for work related to 33 items presented in the study methods, the participants responded that they are currently performing such work or are likely to perform such work in the future, although there were differences by year. Investigation by type of workplace showed that dental hygienists working in university hospitals could perform the work presented if they had ≥5 years of dental hygienist experience, whereas dental hygienists working in dental clinics or hospitals could perform simple duties in their first year and performed more diverse duties with greater degree of difficulty after their second to fourth year. Conclusion: The reality that medical assistance during surgical operations and various procedures that is still being performed is no longer legally protected directly contradicts the needs in dental practice, and thus, there is the need to amend laws that are realistic by clearly recognizing the work of dental hygienists.

Purpose: The purposes of this study were to assess the dentists' subjective satisfaction with the crestal approach sinus (CAS) kit, a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure, and to summarize the subjective satisfaction of dental implants placed after a sinus lift procedure with the CAS kit. Methods: Thirty dental clinicians who had experience with dental implant placement after a sinus lift procedure with the CAS kit from June 2010 to May 2012 were included in this study. The questionnaire for the evaluation of the dentists' subjective satisfaction with the CAS kit was sent to the respondents and returned. The questionnaire was composed of two main parts. The first part was related to the sinus membrane perforation rate. The second part was related to the dentists' subjective satisfaction with the CAS kit. Results: A total of 28 dentists answered the questionnaire. Among 924 implant cases, sinus membrane perforation occurred in 38 cases (4.1%). Among the 28 dentists, 26 dentists (92.9%) were satisfied or very satisfied with the CAS kit. In particular, 24 dentists (85.7%) reported that safety, cutting performance, and user-friendliness of the CAS drill were advantages of the CAS kit. However, 7 dentists (25%) did not routinely use the hydraulic lifter for sinus membrane elevation. Conclusions: From the survey, it was shown that the respondents were generally satisfied with the CAS kit and that the cutting performance and safety of the drill component were considered strengths of the CAS kit.

Total ankle replacement has been performed for treatment of end stage arthritis of the ankle, hopefully being an alternative to ankle arthrodesis. However, due to its high failure rates, earlier versions of ankle replacements were not regarded as successful procedures. The latest design has shown increasingly positive results. Total joint replacement of the ankle itself is still regarded as a demanding procedure and much more challenging than that of the hip and knee in many aspects. Several studies, however, have pointed out that it is becoming the viable, accepted alternative for arthrodesis with advanced implants, appropriate patient selection, and proper training experience of procedures. Compared with arthrodesis, it shows equal or better outcomes in pain relief, range of motion, and patient's satisfaction. We are attempting to review its biomechanical characteristics, implant design, indications, complications, clinical outcomes, and survival rate.

In patients with insufficient bone height and width, the successful placement of dental implants is difficult with regards to maintaining an ideal pathway and avoiding important anatomical structures. Vertical and/or horizontal ridge augmentation may be necessary using various bone substitute materials and bone graft procedures. However, effective one-wall reconstruction has been challenging due to its poor blood supply and insufficient graft stability. In this paper, the authors summarize current evidence-based literature based on the author's clinical experience. Regarding bone substitutes, it is advantageous for clinicians to select the types of bone substitutes including autogenous bone. The most important consideration is to minimize complications through principle-based ridge augmentation surgery. Ridge augmentation should be decided with complete consent of the patients due to the possible disadvantages of surgery, complications, and unpredictable prognosis.

The introduction of acellular dermal matrix (ADM) to breast reconstruction has allowed surgeons to reexplore the prepectoral implant placement technique in postmastectomy breast reconstruction. Our institution adopted a novel approach using meshed ADM to lessen the financial burden of increased ADM utilization with the prepectoral breast reconstruction. This is a retrospective, single-center review of two-stage prepectoral breast reconstruction using meshed human-derived ADM for anterior prosthesis coverage. Patient demographics, oncologic data, perioperative characteristics, and complications were examined and reported as means with standard deviations. Cost-saving with the meshed technique was evaluated. Forty-eight patients (72 breasts) with a mean age of 48.5 ± 15.0 years (range 26-70 years) were included in the study. The mean follow-up time was 13.2 ± 4.4 months (range 4.1-25.8 months). Nineteen breasts (24.6%) experienced complications, with seromas being the most common complication (12.5%, n = 9). Expander removal and reoperation occurred at a rate of 8.3 and 9.7%, respectively. The average time to drain removal was 18.8 ± 6.6 days (range 8-32 days). Meshed ADM provided an average cost savings of $6,601 for unilateral and $13,202 for bilateral reconstructions. Our study found that human-derived meshed ADM can be safely used in two-staged prepectoral tissue expander-based breast reconstruction and can result in significant cost savings.
