The patient in this case was an 80-year-old female who had lost #16, 13, 26, 37, 36, 35, 44, 45, 46, 47 teeth. The patient showed loss of posterior support, loss of vertical dimension of occlusion, and deep anterior overbite. Her chief complaint was esthetic and functional discomfort. She wanted to restore normal facial aesthetic shape and masticatory function through prosthetic treatment. Clinical evaluation, radiographic examinations, and facial and oral analysis were performed. Interocclusal rest space was excessive than the average. Distance between labial vestibules and zenith of central incisors, and lower facial ratio were below the average. Taken together, occlusal rehabilitation was determined through increasing 4 mm of vertical dimension on premolars. In this case, a patient who lacked restoration space with deep bite in the anterior region due to loss of the posterior teeth support restored a stable occlusal relationship and harmonious anterior and lateral guidance through fixed and removable prosthesis with increased vertical dimension.

In the modern society, the awareness of images is affecting the body-related consumer behavior through mass media such as TV and internet, and SNS that has grown explosively with the wide availability of smartphones. As a consequence, the demands for aesthetic treatments by patients who wish to improve their inferiority complex are increasing. Patients who want aesthetic treatments display more active inclinations than those receiving general treatments, and have the expectation for the improvement in images along with the anxiety over potential functional problems and satisfaction about the outcomes. In the consultation of the patient of aesthetic case, the basic starting point is that the surgeon and the patient recognize improvement points that the patient expects through the aesthetic treatment. The consultation starting from the viewpoint of the patient proceeds in a way that the consensus is reached through the medical approach, eventually finding the balance between ideals and naturalness. The consultation process from the initial meeting is established at each stage of treatment, at which the consultation is correctly recorded and shared by the surgeon and the care staff. In addition, the consistent policy is implemented from the initial consultation through to the maintenance care. Together, these will result in the consultation based on the true communications leading to the outcome that satisfies the patient, the surgeon and the care staff, rather than the one that gives the patient an unfounded hope and leads to the unsympathetic outcome. This article introduces the consultation strategy for patients of aesthetic case based on the sympathy with them through cases of aesthetic treatment by type.

The treatment of areas demanding esthetic requirements, such as maxillary anterior teeth, should take into account the achievement of a healthy, harmonious to the surrounding tissue, and an attractive smile line. In this case report, smile line, soft tissue and hard tissue morphology, and the anatomy and proportion of the tooth, must be considered. In patients with unesthetic maxillary anterior ratio due to inadequate gingival contour and diastema caused by peg lateralis, it would be challenging to achieve an esthetic restoration by orthodontic treatment alone. In such case, after orthodontic treatment, dento-gingivo-facial compositional diagnosis and analysis, followed by gingivectomy and prosthodontic restoration is needed to improve the interdental mesial/distal, width/length ratio to achieve a satisfactory esthetic result. In addition, when improving the tooth proportion of peg lateralis by prosthodontic treatment, Porcelain laminate veneer (PLV), which results in less tooth structure loss, reproduction of similar shade to that of the proximal tooth and high transparency, is recommended. This case report demonstrates esthetic improvements by prosthodontic restoration through systematic diagnosis and treatment procedure in patients with unesthetic maxillary anterior proportion after orthodontic treatment due to peg lateralis by means of two female patients aged twenty years old.

It is considered an implant failure when there is esthetic problems in the anterior area although the prosthesis function normally. In 2003, Dr. Kan et al stated that implant bone level is determined by the adjacent teeth. After that many scholars have studied how can achieve the esthetics result on adjacent teeth bone loss cases. In 2012, Dr. Takino published an article in Quintessence. He summarized previous articles and reclassified the defects from class 1 through 4. Class 1 and 2 depicts a situation where there is no bone loss on adjacent teeth. In Class 3 and 4, interproximal bone loss extends to the adjacent tooth. If one side is involved, it is Class 3. If both sides are involved, it is Class 4. The clue for esthetic implant restoration is whether bone loss extends to adjacent tooth or not. If the bone level of adjacent tooth is sound, we can easily achieve the esthetic but the bone level is not sound, the surgery will be complicated and the esthetic result will be unpredictable. So regenerative surgery for adjacent tooth is necessary for long-term maintenance. But the options and process were so complicated, the purpose of this article is to report the method simplify the surgery and gain a similar outcome.

Injuries of permanent teeth by trauma occur frequently in childhood and adolescence. Crown fractures are as frequent as 25-76% and especially maxillary incisors are prone to fractures. There have been numerous efforts to achieve both aesthetically and functionally satisfying restoration. When a mature tooth is fractured, porcelain crown or laminate veneer could be a choice of prosthodontic treatment. However, in a case of immature permanent incisor fracture, prosthodontic treatment is more complicated due to the immaturity of the tooth. Moreover, if endodontic treatment is accompanied with the prosthodontic treatment, the treatment period is prolonged. In the past, restoration using an orthodontic band, a ready-made crown, or glass ionomer cement did not exhibit esthetically satisfying result. As restorational materials have been improved, now more esthetic restoration is possible by reattaching fractured fragments or light-curing composite resin restoration. We reports cases of patients with fractured maxillary incisors and their successful treatment results through reattachment of fractured fragments and composite resin restoration.

Complicated crown fractures of maxillary anterior teeth caused by trauma in adolescence can cause functional and aesthetic problems. For crown fractures with pulp exposure, various restorative methods can be considered depending on the amount of remaining tooth structure. Direct resin restorations are the most traditional and effective method, but they are likely to discolor and break over time. Fixed prosthesis have a high possibility of re-restoration due to marginal disharmony due to tooth movement during the growth period, and restorations using post which are mainly performed for extensive crown fractures increase the risk of root perforation and root fracture. However, endocrown is an integrated structure that gains retention force from the pulp space, enabling effective reconstruction from a biomechanical perspective and providing advantages in restoring function and aesthetics. Therefore, endocrown can be considered as a restoration method for complicated crown fractures caused by trauma in adolescence.

Tooth bleaching was being done more than 100 years ago, but the standard for vital tooth bleaching for the last quarter century has been the use of hydrogen peroxide with heat or with a combination of heat and light. The major disadvantages of this process are high cost, unpredictability of results, and patient discomfort. In March, 1989, the dental world was introduced to a new vital tooth bleaching process by Haywood and Heymann in their article "Nightguard vital bleaching(NGVB)." Interestingly enough, this simple technique could have been developed years ago if we had known about the chemical effects of carbamide peroxide on tooth structure. NGVB has created a resurgence in the area of bleaching, primarily because of its relative ease of application, the safety of the materials used, low cost, and the high percentage of successful treatments. This article was to explain simply about all around NGVB(etiology of stains, bleaching chemicals and mechanisms, bleaching effectiveness, side effect, documentation, indications, treatment therapy, laboratory procedure, case reports)

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.

In recent years, as a burden on tooth preparationduring the processing the laminate veneer treatments to enhance aesthetics, the interests and demands for non-prep laminate veneers are increasing which do not require teeth preparation. Although there are clear limitationsbecause the restorations are fabricated without tooth preparation, there is a clear advantage of non-invasivehealthy teeth. When manufacturing a non-prep laminate veneer, an effective design should be selected according to the aesthetic requirements and intraoral condition because the margin of restorationsshould be determined on the natural tooth surface that isnot prepared. In this article, I would like to presentthe three different designsaccording to the range which teeth are covered, and the advantages and disadvantages of them. Non-prep laminate veneer introduced in this article was fabricated using Lithium disilicate press ingot.
