Recently, a method of fabricating an esthetic anterior fixed prosthesis by integrating data such as three-dimensional facial scan and jaw motion to form a virtual patient with dynamic occlusion has been introduced. This enables smooth communication with patients during the diagnosis process, improves the predictability of esthetic prosthetic treatment, and lowers the possibility of occlusal adjustment. In this case report, a virtual patient with dynamic occlusion was created in which the results of the treatment were simulated, and esthetic maxillary anterior fixed prosthesis was fabricated. With the aid of the virtual patient, the final restorations were satisfactory both in terms of esthetic and function.

I think the following conditions should be met for a successful anterior aesthetic restorations. They include the patient's facial and dental harmony, the coordination between the tooth and periodontal tissue, and the continuity with the adjacent teeth. However, in the laboratory process of making restorations, the dental technician works on the model without meeting the patient in person, so he or she has to rely on his or her knowledge and skills to make restoration within limited information. In this article, I discuss the biological criteria that I think as a dental technician and the forms of restorations and how to grant them to the sound periodontal condition.

Periodontal tissue destroyed by inflammation is difficult to achieve regeneration of the tissue and esthetic restorations only by surgical methods. In particular, improvement of esthetics is more difficult if the problem is related to the implant. A 23 year old woman suffered from unesthetic anterior implant prosthesis. According to her dental history, a repeated bone graft and soft tissue graft failed at a local dental clinic. It was needed to resolve the inflammation and to improve the esthetics. A free gingival graft and ridge augmentation accompanied by guided bone regeneration and a vascularized interpositional periosteal connective tissue graft was performed. Instead of implant prosthesis, a conventional fixed bridge was adopted for better esthetic result. The patient was satisfied with the esthetic conventional fixed prosthesis. This case report introduces esthetic rehabilitation of unesthetic implant prosthetics in the maxillary anterior dentition by a combination of surgical and prosthetic approaches.

Successful treatment in the anterior esthetic prosthetic can be a balance between aesthetics in the facial, tooth, and periodontal tissue in the oral. In the case of facial symmetry of patients with normal occlusal plane, If you establish criteria of finding balance of aesthetics such as a several books and articles and manufacture a prostheses by the established-criteria, you can manufacture a harmonious and aesthetic prostheses without any trouble. However, in the case of patients with facial asymmetry, if you manufacture a tooth as patient's facial aesthetic symmetry by force even facial asymmetry case, you can't get a result not only aesthetic but also functional prostheses. Also, to produce the prosthetic of harmonious and aesthetic with periodontal tissue, and excellent self-cleansing function, you must apply to the form of the prosthetic changed dental environment.

Restoration of missing oral tissues by using implant therapy is one of viable options in prosthodontic treatment. The purpose of oral rehabilitation are function, esthetics and phonetics. Recently, with the increasing esthetic demand of the patient, dentists and laboratory technicians are more concern ed about natural appearance of implant prostheses. There are so many factors which affect final esthetic results of treatment such a shape, color, proportion, gingival contour etc. To provide natural and vivid looking artificial prostheses to a patient, the careful diagnosis, treatment plan and laboratory Support is crucial. Several cases will be reviewed and discussed in terms of material, gingival shape, contour, speech and connection mode etc. to fabricate natural looking implant prostheses.

Recently, there are cases where anterior esthetic prostheses are fabricated for better esthetics, but biologic, mechanical factors could be overlooked, too focusing on esthetic factor. This leads to changes in neutral zone, dentition, position of tongue and lips, occlusion and anterior guidance causing inaccurate pronunciation. Therefore, consideration of systematic diagnosis and treatment procedure are required. In this case, prosthesis was refabricated through a systematic diagnosis and treatment procedure using four factor (acoustic analysis, esthetic analysis, occlusion, neutral zone) for the patient who complained of inaccurate pronunciation and esthetics of the fixed prosthesis fabricated 10 years ago. Thus, by promoting functional, esthetic recovery, this case report demonstrates satisfying results to both the patient and dentist.

전치부 발치 증례에서 기존의 통상적인 보철 시술은 발치 후 발치창이 치유되기까지 최소 1 개월 이상을 심미적 결함을 안고서 기다려 한다는 불편함이 있었다. 발치 부위의 치조제는 수평, 수직적 흡수가 일어나 차후 보철물 pontic design에 악영향을 미치게 되어 심미적 결함뿐 아니라 발음, 구강 청결의 측면에서도 좋지 않은 결과를 미치게된다. 그러나, 발치 직후 ovate pontic을 이용한 immediate fixed restoration으로 수복하면, 치아 상실로 인한 환자의 기능적 심미적 불편함을 해소하고, 치료 과정은 물론 치료 후에도 보다 나은 심미 치료가 가능하며, 치료의 공백 기간 없이 치료 기간을 줄일 수 있다.

Various materials and restorative options have been introduced recently with growing interest in esthetic dental treatment in modern society. Zirconia is especially known for its biocompatibility as well as remarkable toughness and resistance to wear, but it is limited in its use for esthetically focused treatment in anterior region for its white opacity. Lately the development of different kinds of zirconium blocks, such as colored block, clear block, and multi-layered block, allowed more extensive use of zirconia as a treatment option. This report describes a case, in which a prosthetic crown maxillary anterior region was stained with a combination of various coloring liquids before sintering to reproduce natural-looking color scheme in final restoration. The case was reported as the utilization of coloring liquid on monolithic zirconia crown could achieve esthetically satisfying prosthesis for both dentist and patient.

Recently, many patients undergo anterior prosthetic treatment for esthetic reasons. In some patients complain about functional reasons such as inaccurate pronunciation and occlusal discomfort after the treatment. Anterior teeth are important esthetically but in the occlusal point of view, anterior guidance is the second most important factor in occlusion, next to centric relation. Failure to determine an appropriate anterior guidance might lead to posterior occlusal interference, which can highly affect the stability of the posterior teeth. Also, discomfort might occur if the customized interior guidance is not in harmony with the patient's envelope of function. The patient in this case complained of overall discomfort in the maxillary anterior area after prosthetic treatment. The expressed difficulty in pronunciation, unstable occlusion due to lack of stable holding contact and discomfort of the facial muscles. Maxillary anterior prostheses were refabricated through systematic diagnosis and treatment and thus, this case presents esthetical and functional satisfaction to both the patient and the dentist.

경제적인 수준의 향상과 환자의 심미에 관한 요구도가 높아짐에 따라 금속이 없는 수복물, 특히 세라믹으로 구성된 완전도재관을 이용한 보철 수복이 점차로 증가되는 추세이다. 현재까지 발표된 문헌에 의하면 강도보다는 심미가 더 요구되는 부위에는 Glass ceramics 를, 심미보다는 강도가 더 요구되는 부위에는 지르코니아 세라믹을 이용한 완전전장관이나 고정성 국소의치를 제작하는 것이 일반적으로 추천되며, 그 수복물의 장기간의 성공적인 기능을 위해서는 올바른 접착 방법을 이용하는 것이 중요하다.
