  • This paper is the first paper among two papers which constitute the paper about the structural design of a dental implant. This paper surveyed types and characteristics of dental implants. Merits and shortcomings of clinically used dental implants were analysed through this survey. A new structural model of dental implant was proposed on the basis of survey results. Especially, a comparative structural analysis of the new dental implant and the well known dental implants has been performed using the finite element analysis method. The analysis results confirm that the newly proposed dental implant has a good structural performance. The well known dental implants used for the comparative structural analysis are 3i implant and Sargon implant. These implants are imported dental implants and we could know that most implants clinically used are endosteal implants and these two implants(3i implant and Sargon implant) are also endosteal implants.

  • Nowadays, dental implant is one of the widely used treatment options for edentulous patients. Recently, a method of improving the accuracy of implant surgery using an implant surgical guide has been introduced and widely used in order to accurately place the implant in a proper position. Full-guided and half-guided implant surgery can be distinguished according to the level of surgical guide application during the implant surgery. It is true that full-guided implant surgery exhibits higher accuracy, but half- guided implant surgery is often performed in a clinical situation due to the factors such as the circumstances of the operation. A partially edentulous patient who lost teeth due to tooth fracture and periodontal disease was treated using implant and fixed prosthesis. Half-guided implant surgery was performed using an implant surgical guide during implant surgery, the accuracy of implant placement was analyzed.

  • This paper is the second paper among two papers which constitute the paper about the structural design of a dental implant. This paper completed the test drafting for the structural model of the new dental implant whose structural performance was confirmed and verified through the comparative structural analysis carried out in the first paper. This paper finished the structural design of a dental implant by manufacturing the dental implant using CNC machines and so forth on the basis of the completed draft and finally by evaluating the machining condition of the dental implant. The drafting work was performed using MDT(Mechanical Desk Top). The manufacturing work was carried out using CNC machines, general purpose milling machine, and Wire EDM. The manufactured surface condition of the dental implant was evaluated and confirmed finally using an electron microscope. As a result of evaluation, a testing dental implant with very good condition was designed and manufactured.

  • 치과용 임플란트(Implant)란 상실된 자연치아를 대신하여 골 내에 매식하는 인공치근을 말한다. 임플란트는 인접 자연치아의 보호, 심미적 안정 등의 장점으로 인해 그 수요가 늘어나고 있으며, 단일치아 임플란트의 경우, 부분 무치악 환자들에게 있어서 우수한 치의학적 해법이 되어왔다. 대부분의 임플란트는 두 개 이상의 구성요소로 이루어져 있으며, 각각의 구성요소는 나사에 의해 결합되어 있다. 많은 연구결과를 통해, 임플란트의 나사 풀림 현상(Screw loosening)은 임플란트와 관련하여 가장 흔한 문제로 나타나고 있다.(중략)

  • Currently, dental implants have become predictable and reliable adjuncts for oral rehabilitation. Osseointegrated implants can be used to provide rigid orthodontic anchorage and have advantages compared conventional orthodontic anchorage especially when there were edentulous areas and implants were scheduled as a treatment plan. Orthodontic force doesn't cause the bone loss of osseointegrated implants. Implant materials, surgical protocols and healing time before loading follow the conventional treatment protocol. Because the implants, once installed, can't change the location, meticulous treatment planning should be preceded. Further investigations are needed to standardize the treatment protocol.

  • One of the fastest growing segments of implant dentistry is the utilization of computed tomography (CT) scan data and treatment planning software in conjunction with guided surgery for implant reconstruction cases. Computer assisted planning systems and associated surgical templates have established a predictable, esthetic, functional technique for placing and restoring implants. Especially, a philosophy of restoratively driven implant placement has been generally adopted. Recently, a variety of commercial dental fields have released their scanning and fabricating protocols and methods for restorations. This process is still being investigated and developed for the most precise and predictable outcome. This case report describes a female patient who wanted dental implants in fully edentulous areas. Restoratively driven implant placements were performed with surgical guide and the patient was fully satisfied with the clinical results, and at 5-year post restorative follow-up assessment, both implant and prosthesis were proved clinical success.

  • Bone and soft tissue conditions are important for successful implant treatment. But, the placement itself is also very important. Implants which is installed in the wrong position result in the biological, esthetical and mechanical problems. In order to place an implant in the correct position, the final restoration and diagnostic wax-up should be considered prior to the surgery. If the artificial teeth for the interim denture are directly transferred from the diagnostic wax-up, the operator can try the form of diagnostic wax-up in the mouth. If the surgical template is produced by duplicating the interim denture, the implant can be placed in the planned position. In this case, the polymethyl methacrylate (PMMA) artificial tooth was precisely milled by the digital duplication of diagnostic wax-up. And interim denture was fabricated by using these milled teeth. After the patient adapted for a sufficient period, the implant was placed at the planned position with surgical template produced by duplicating the interim denture. After confirming sufficient osseointegration, the final prostheses were made to reflect the shape of diagnostic wax-up. Through this procedure, the satisfactory functional and esthetic outcome could be acquired.

  • With the recent progress of digital technology, the computer guided surgery utilizing a guide template in the placement of implant has been actively performed, and the method employing the intraoral scanner at the implant prosthesis introduced. Fabrication method of the guide template can be largely classified into design-related rapid prototyping (RP) system and vector milling system, and each of the method has its own weakness in the clinical application despite of excellent accuracy. Thus, in this case study, a working model was fabricated by the wax RP technology using images acquired by CBCT and an intraoral scanner, and the metal bushing was picked up with orthodontic resin cast upon the wax model. Using this method, a surgical guide template was fabricated and used in surgery. From this, we could obtain a satisfactory outcome clinically in the implant placement and the fabrication of the final prostheses and thus report this case herein.
