In the case of failed fixed implant prosthesis accompanied by abutment screw fracture, fractured screw fragment must be removed to use the existing implant fixtures. A 61-year-old male patient, who had a failed maxillary fixed implant prosthesis accompanied by three abutment screw fracture, hoped to reconstruct the maxillary implant prosthesis, while maintaining the existing implant fixtures. To use the existing implant fixtures, fractured screw fragments were removed. A maxillary implant overdenture using available existing implants was planned. Bar-attachment with Locator was used for implant splinting, denture stability, and retention. Final impression was taken after treatment of peri-implantitis. Jaw relation registration was taken to evaluate available interarch space for bar-attachment. After fabricating bar-attachment, centric relation was taken. Implant overdenture using bar-attachment with Locator was delivered after wax-denture evaluation. This case report showed that a satisfactory clinical result was achieved by implant overdenture using existing implant fixtures in a maxillary edentulous patient.

The purpose of this study was to examine dental hygienists' knowledge of implant operation, which is recently emerging as one of the important medical services in the dental treatment sector. It's ultimately intended to serve as a basis for the preparation of more effective, appropriate implant-education programs for dental hygienists and to help them, who take a crucial part in implant operation, provide better dental services to patients who are in need of implant operation. The subjects in this study were 368 selected dental hygienists who were working in the dental institutions in the region of Taegu. The results of this study were as below: 1. The largest number of the dental hygienists investigated, 34.1%, were at age 25 to 27. The second most common age was 24 and under, and the third most common age group was 28 to 30. For educational level, most of them, 91.0%, were junior-college graduates, and 9.0% were being in or graduated from four-year-course university. Concerning career, 52.7%, the greatest percentage, had worked for one to three years, and 41.3% had a four-year or higher career. 812%, most of them, were working in dental clinics, and 18.3% were serving in dental hospital or general hospital. 2. Many of the dental institutions were providing implant operation services, as the dental institutions where 64.9% of the subjects were working conducted implant operation. In relation to the necessity of implant operation, the dominant opinion, 73.0%, was thai it's needed to make oral slate healthier. So there was a strong tendency to ad mit implant as one of the necessary treatments in the dental treatment sector. 3. Their collective mean implant knowledge got $57.02{\pm}14.11$. And the collective average of 21 items was $2.7153{\pm}0.6720$ on the basis of 5 points, which was below the average(3 points of Likert scale). This meant that the dental hygienists didn't have a good knowledge or understanding of implant. When it's taken into account what role should be performed by dental hygienists, their implant knowledge should be increased. 4. As a result of examining the effect of the general characteristics on their implant knowledge, the educational level(t=-3.481, P=0.001) and the type of dental institution where they were working(F=16.476, P=0.001) made a significant difference. 5. Their implant knowledge was significantly different according to whether or not the dental institution they were serving conducted implant operation (t=7.199, P=0.001). And, whether or not they agreed to the necessity of implant operation also generated a significant difference to their implant knowledge(F=8.610, P=0.000).

PURPOSE. The aim of this study was to evaluate the clinical findings and patient satisfaction on implant overdenture designed with Locator implant attachment or Locator bar attachment in mandibular edentulous patients. MATERIALS AND METHODS. Implant survival rate, marginal bone loss, probing depth, peri-implant inflammation, bleeding, plaque, calculus, complications, and satisfaction were evaluated on sixteen patients who were treated with mandibular overdenture and have used it for at least 1 year (Locator implant attachment: n=8, Locator bar attachment: n=8). RESULTS. Marginal bone loss, probing depth, plaque index of the Locator bar attachment group were significantly lower than the Locator implant attachment group (P<.05). There was no significant difference on bleeding, peri-implant inflammation, and patient satisfaction between the two denture types (P>.05). The replacement of the attachment components was the most common complication in both groups. Although there was no correlation between marginal bone loss and plaque index, a significant correlation was found between marginal bone loss and probing depth. CONCLUSION. The Locator bar attachment group indicates lesser marginal bone loss and need for maintenance, as compared with the Locator implant attachment group. This may be due to the splinting effect among implants rather than the types of Locator attachment.

In spite of appropriate treatment of peri-implantitis, the peri-implant bone loss was keep going, the clinician should remove the osseointegrated implant. the conventional methods are like a extraction of natural teeth, and use of trephine drills. In these days, many exclusive instruments are invented by implant companies. these instruments can make easy, least invasive, less traumatic removal of osseointegrated implants. In generally peri-implant bone loss progress steadily less sign and symptoms that the patient do not want to remove their implants. However, the failure of dental implant is big burden to clinicians and also patients. In the dental implant treatment, there is no 'failure' but only is 'replacement' or 'change'.

Purpose: With the popularity of implant therapy, clinicians need to know about treating the dental implant in patients with gingival involvement of oral lichen planus (OLP). The aim of this study is to evaluate the survival and success rates of dental implant and propose of clinical guidelines for implant treatment in OLP patient with gingival involvement. Methods: A literature search was performed in PubMed/Medline, and Cochrane database. Papers in English language published between 1990 and 2019 were evaluated. The focused questions were following; 1) Dose gingival OLP affect the survival and success rates of dental implants? 2) The management of OLP patients with gingival involvement receiving dental implant. Results: There was no study about the evaluation of dental implant only in gingival OLP patient. Five studies evaluating dental implants in OLP patients were included in this review. Implant survival rate was 100.0% in well-controlled OLP patients in all included studies. The use of topical/systemic corticosteroid in OLP patients was performed before and/or after implant placement in all included studies. Conclusions: The implant survival and success rates in well-controlled OLP patients did not different from that of non-OLP healthy subjects. The gingival OLP is associated with higher rate of peri-implant mucositis. Adequate management of gingival OLP lesions before and after implant insertion is required to reduce inflammation and associated bone loss.

Implant treatment has become the treatment of choice to replace missing teeth in partially edentulous areas. Dental implants present different biological and biomechanical characteristics than natural teeth. Occlusion is considered to be one of the most important factors contributing to implant success. Most literature on implant occlusal concepts is based on expert opinion, anecdotal experiences, in vitro and animal studies, and only limited clinical research. Furthermore, scientific literature regarding implant occlusion, particularly in implant-supported fixed dental prostheses remains controversial. In this study, the current status of implant occlusion was reviewed and discussed. Further randomized clinical research to investigate the correlation between implant occlusion, the implant success rate, and its risk factors is warranted to determine best clinical practices.

Surgeon dentists usually rely on their experiential judgments from patients' oral plaster casts and medical images to determine the positional and directional information of implant fixtures and to perform drilling tasks during dental implant surgical operations. This approach, however, may cause some errors and deteriorate the quality of dental implants. Computer-aided methods have been introduced as supportive tools to alleviate the shortcomings of the conventional approach. In this paper, we present an approach of 3D dental implant simulation which can provide the realistic and immersive experience of dental implant information. The dental implant information is primarily composed of several kinds of 3D mesh models obtained as follows. Firstly, we construct 3D mesh models of jawbones, teeth and nerve curves from the patient's dental images using software $Mimics^{TM}$. Secondly, we construct 3D mesh models of gingival regions from the patient's oral impression using a reverse engineering technique. Thirdly, we select suitable types of implant fixtures from fixture database and determine the positions and directions of the fixtures by using the 3D mesh models and the dental images with software $Simplant^{TM}$. Fourthly, from the geometric and/or directional information of the jawbones, the gingival regions, the teeth and the fixtures, we construct the 3D models of surgical guide stents which are crucial to perform the drilling operations with ease and accuracy. In the application phase, the dental implant information is combined with the tangible interface device to accomplish 3D dental implant simulation. The user can see and touch the 3D models related with dental implant surgery. Furthermore, the user can experience drilling paths to make holes where fixtures are implanted. A preliminary user study shows that the presented approach can be used to provide dental students with good educational contents. With future work, we expect that it can be utilized for clinical studies of dental implant surgery.
