Implant assisted removable partial denture (IARPD) has been practiced in various forms for a long time, and among them, implant surveyed crown RPD is gaining predictability as well as being considered as a treatment option for patients with anatomical and financial disadvantages. The position of implant could be divided as posterior placement or anterior placement according to the purpose of the treatment and should be planned in consider to the alveolar ridge of patient, anticipated prognosis of remaining teeth, and opposing dentition. This case report describes a treatment for mandibular Kennedy class I partial edentulous patient with two implant-supported surveyed crown and implant assisted removable partial denture. Given the difficulty of posterior placement in this patient and the prognosis of the residual teeth, the plan was to place two implants in close proximity to the residual teeth, which were placed in the planned position, angle, and depth using guided surgery. The process of fabricating the fixed prosthesis was carried out in parallel with the maxillary edentulous tooth arrangement process to increase predictability, and when fabricating the localized tooth, the implant was designed in a form that allows the patient to perform functional movements by preventing excessive loading as the last supporting tooth, and was fabricated through a secondary impression process. Each treatment procedure was proceeded as planned, with aesthetically and functionally satisfactory results for both patient and operator.

This clinical case highlights the failure of long length implants, and the prosthodontic procedures necessary to rehabilitate the maxillary dentition of a patient with microstomia. The integrated digital technology of intra-oral scanning, computer-aided design, and three-dimensional printing can provide an alternative method to make conventional impressions for patients with microstomia who cannot insert the appropriate tray in their mouths.

Loss of dentition can lead to not only compromised esthetics and functions of the patient, but also alveolar bone resorption. Bone grafting with prosthetic reconstruction of the gingiva can be selected for the treatment, and it provides many benefits as prosthetic gingival reconstruction does not require a complicated surgical process and is available within a short period of time, with stable clinical results. However, conventional porcelain fused to metal prosthesis has certain limits due to its size, and deformation after several firing procedures. In this clinical report, the author would like to introduce a patient with severe alveolar resorption who was treated with gingiva-shaped zirconia/titanium CAD/CAM implant fixed prosthesis for esthetic and functional rehabilitation. Clinical reports Clinical report 1, 2 : A case of loss of anterior dentition with atrophied alveolar bone. Implant retained zirconia bridge applied with Procera implant bridge system to simulate the gingiva. Upper structure was fabricated with zirconia all ceramic crown. Clinical report 3, 4 : A case of atrophied maxillary alveolus was reconstructed with fixed implant prosthesis, a CAD/CAM designed titanium structure covered wi th resin on its surface. Anterior dentition was reconstructed with zirconia crown. Conclusion and clinical uses. All patients were satisfied with the outcome, and maintained good oral hygiene. Zirconia/titanium implant fixed prosthesis fabricated by CAD/CAM system was highly accurate and showed adequate histological response. No critical failure was seen on the implant fixture and abutment overall. Sites of severe alveolar bone loss can be rehabilitated by implant fixed prosthesis with CAD/CAM system. This type of prosthesis can offer artificial gingival structure and can give more satisfying esthetics and functions, and as a result the patients were able to accept the outcome more fondly, which makes us less than hard to think that it can be a more convenient treatment for the practitioners.

Recently, digital implant systems are expanding its influence in dental area. Due to technical improvement, they jumped over their limits nowadays. We can use these newest systems to treat edentulous patient, from implant surgery to fabrication of prosthesis. In this case, The patient was a fifty years old female. She had a full edentulous ridge on mandible and wanted to reconstruct occlusion with using implants. We planned to use digital implant system with "all-on-4" concept on mandible and produced surgical guide for flapless implant surgery. After the surgery, we tried to fabricate full arch prosthesis just using a digital devices and confirmed satisfying result.

Objectives : The purpose of this research was to investigate the awareness of an adult on implants and the relevant factors which affect the satisfaction of a patient after an implant treatment. Methods : This study was conducted to 407 adult subjects in Seoul and Gyeonggi. A total of 384 data were analyzed except the questionnaires having poor responses or errors. Results : The acquaintance route of implant was TV advertisements, self-knowledge, internet, news, and newspapers. Dentist's ability to practice implant was the most important factor in patient's choice. The responents answered the expected lifespan of an implant was more than 5 years to 10 years. In terms of dental health management behavior on implants, the average response of the highest 4.07 points of 5 Likert scale. Generally women are more concerned with implant than men(p<0.01). The highly educated and elderly patients had tendency to receive more treatment(p<0.0001). Patients were more satisfactory after receiving regular checkups after treatment(p<0.05). The low expenses of implant satisfied the patients(p<0.05). Conclusions : As implant technology advances, the concern of patients on implants also increase. So reduction of cost can make the patients have access to the dentist and the patients' oral health must be improved through continuous dental care.

Background The latissimus musculocutaneous flap (LD flap) is a useful option for breast reconstruction following mastectomy. It has the advantage of obtaining sufficient tissue padding and natural shape by using autologous tissue. However, with the emergence of the skin-sparing mastectomy technique and artificial dermis matrix, direct-to-implant (DTI) breast reconstruction has become the first choice of surgery. The purpose of this study was to compare the satisfaction levels of patients who underwent DTI and LD flap with implant using patient-reported Breast-Q results. Methods A retrospective study was performed reviewing the records of 49 women who underwent immediate breast reconstruction with DTI or LD flap with implant and responded to the BREAST-Q questionnaire after the operation. The patient-reported breast-Q results were analyzed and correlated to the demographic information and intraoperative information. Results A total of 26 patients who underwent reconstruction with LD flap with implant and 23 patients with DTI were identified and responded to the questionnaire after an average of 32.3 and 10.4 months postoperation, respectively. According to the patient response to the breast-q values, satisfaction with breast was 60.0 and 57.0 points, psychosocial well-being 61.0 and 60.0 points, and sexual well-being 41.0 and 43.0 points in the two groups. Overall, there was no significant difference in the breastQ score between the two groups. Conclusion Patients who underwent DTI breast reconstruction seemed equally satisfied with the appearance and outcome of their breast reconstruction compared with LD flap with implant. Therefore, it appears that DTI is adequately replacing LD with implant.

Breast implants whether used for cosmetic or reconstructive purposes can be placed in pockets either above or below the pectoralis major muscle, depending on clinical circumstances such as subcutaneous tissue volume, history of radiation, and patient preference. Likewise, cardiac implantable electronic devices (CIEDs) can be placed above or below the pectoralis major muscle. When a patient has both devices, knowledge of the pocket location is important for procedural planning and for durability of device placement and performance. Here, we report a patient who previously failed subcutaneous CIED placement due to incision manipulation with prior threatened device exposure requiring plane change to subpectoral pocket. Her course was complicated by submuscular migration of the CIED into her breast implant periprosthetic pocket. With subcutaneous plane change being inadvisable due to patient noncompliance, soft tissue support of subpectoral CIED placement with an acellular biologic matrix (ABM) was performed. Similar to soft tissue support used for breast implants, submuscular CIED neo-pocket creation with ABM was performed with durable CIED device positioning confirmed at 9 months postprocedure.

Often there are edentulous patients with severe vertical resorption of the alveolar ridge so that implant placement in the mandibular posterior is impossible. In this case, implants can be placed in the anterior portion of the mandible and the patient can be treated with an implant assisted overdenture, but the inherent discomfort of the removable prosthesis can not be overcome. However, if implants are appropriately placed between the mental foramen of both sides and a fixed hybrid prosthesis is fabricated to the patient, the patient will be satisfied without the inconvenience of the removable prosthesis. However, the treatment plan should be well designed to prevent disadvantages and expected complications of fixed hybrid prosthesis. Based on my clinical experience, I will explain treatment plan and protocol in detail.

Conventional implant protocols required a load-free healing period of three to six months between placement and functional loading of the implants. Many efforts have been made to minimize the duration of treatment time. Several literatures have documented immediate function with provisional or definitive prosthesis within a week of the placement in response to these demands. In addition, immediate implant placement has advantages such as shortened treatment time and preservation of soft tissue architectures. This article presents immediate implant placement into fresh extraction sockets followed by functional immediate loading with provisional prosthesis on canine and premolars for a patient having canine protected occlusion.

Presurgical prosthetic treatment planning is critical for the success of the implant prosthesis. Inadequate treatment plan, due to insufficient discussion between prosthodontist, and surgeon, may result in poor prognosis. A 26-year-old male patient was referred for prosthodontic treatment after implant was placed in the area of teeth #17,16, 22, 25 and 27, without adequate discussion nor the treatment planning between oral surgeon and prosthodontist. It was found that the patient had two hopeless teeth, and a severely resorbed alveolar ridge. Additional tooth extraction was needed and the type of definitive prosthesis was shifted from fixed type to removable one. Proper pre-surgical treatment planning is essential for the good prognosis. Implant-supported removable prosthesis on milled bars may be a useful treatment option in patients with incorrect angled placement on severely resorbed alveolar ridge.
