Generalized severely worn dentition causes occlusal disharmony, esthetic problems, and temporomandibular joint disorders. In order to solve these problems, it is necessary to make a precise analysis of vertical dimension and treatment plans considering it. This case report demonstrates the complete mouth rehabilitation of a 58-year-old male patient with a lot of worn teeth by increasing vertical dimension. Provisional restorations were cemented and after 4 months of evaluation for patient's compliance, permanent prostheses were fabricated. With these treatments, functionally and esthetically satisfactory results were obtained.

최근 심미적인 보철 치료에 대한 사람들의 관심이 높아짐에 따라 자연치와 더욱 조화롭게 보철 치료를 하는 것이 요구되고 있다. 이는 구조적인 심미성과 함께 자연스러운 색조 재현을 통하여 이루어지는데, 자연치의 색조는 매우 다양하고 부위별로 달라질 수 있기 때문에 단순히 shade guide상의 비교만으로는 정확한 색조를 얻기가 어렵다. 이러한 색조 선택의 부정확성 때문에 객관적으로 색조를 분석하는 많은 기계적 장치들이 고안되었고, 최근에 ShadeScan system(CYNOVAD, Canada), Vita Easyshade system(Vident, Canada) 등 디지털로 색조를 평가하는 시스템이 각광을 받고 있다. ShadeScan system은 한 번의 클릭으로 치아 이미지를 채득할 수 있고, 바로 컴퓨터를 통해서 이를 분석하여 원하는 shade map, translucency map 등을 얻을 수 있다. 또한 세 방향에서 조사되는 빛은 자체 calibration을 거쳤기 때문에 주변 광원이나 환경의 영향 없이 객관적으로 치아의 이미지를 채득할 수 있다고 한다. 사실 그 동안 이미지 채득이 객관적이라고 주장하는 많은 system이 있었지만 임상의들은 그 신뢰성에대해 의구심을 보였던 것이 사실이다. 이에 본고에서는 ShadeScan system이 반복 촬영 시 같은 색조재현을 할 수 있는지 실험하여 그 객관성에 대해 살펴보았다.

The maxillary anteriors play an important role in esthetics. Therefore after extraction, it is crucial to preserve the hard tissue and soft tissue in order to promote esthetics of restoration. There are several challenges when restoring the maxillary anteriors via implant. Some of the challenges are be maintaining consistency with neighboring teeth in terms of shade, form, and texture : as well as having harmonious emergency with the gingival margin. In this case, a traumatized patient with crown-root fracture of the maxillary central and lateral incisors is presented. The cracked teeth were extracted, and implants were inserted with bone grafts to compensate the volume of damaged area of the maxillary anterior. Cantilever implant prosthetics were planned while precise adjustments to the gingival area were made using customized impression coping to perform the esthetic restorations. The final outcome of the treatment was satisfying in both esthetic and utilitarian perspective.

To enhance the esthetic appearance, the maxillary anterior area is important. It is possible to improve the esthetic appearance through the treatment of maxillary anterior area, which includes altering the color, form, and arrangement of teeth. When planning these treatments, clinicians should individualize personal demands, by using the information obtained from facial, dento-labial, dental, and gingival analysis. It is essential to properly prepare the gingival structure, which includes the height of gingival margin, the location of zenith, reconstruction of the interdental papillae, emergence profile, and symmetry. Clinicians often face unfavorable condition of the gingiva and the edentulous ridge, and appropriate management of the gingival structure is needed. In this case report, the patients were treated to improve the gingival conditions surrounding maxillary anterior teeth. By using conservative treatment without surgical intervention, such as application of pink porcelain, subgingival contour modelling and modification of pontic base, satisfactory esthetic results were gained.

It often happens that a removable partial denture needs to be repaired due to tissue changes in the remaining alveolar ridge, fracture of the denture, or fracture of the abutment tooth. There are several advantages to retrofitting a customized surveyed crown under the existing RPD. Retrofitting a crown to the RPD decreases the economic burden to the patient and avoids the need for several appointments to fabricate a new RPD. It is difficult for artificial teeth used to repair dentures due to fractured natural teeth to have a shape similar to that of natural teeth, and to repair aesthetic artificial teeth, it is necessary to manufacture customized artificial teeth similar to the shape of each patient's teeth. Recently, CAD/CAM technology has been used to fabricate customized prosthetics on existing RPD to achieve high retention and fitness accuracy, and by manufacturing customized artificial teeth, more aesthetic and harmonious artificial tooth repair is possible. This is a case in which a denture was repaired using a digital method to fabricate a customized prosthesis on an existing partial denture and customized artificial teeth that mirrored the adjacent dentition, saving time and cost, simplifying the process, and achieving aesthetically and functionally satisfactory results.

In the case of an extraction in the maxillary anterior region, immediate placement of implant-supported fixed prosthesis can be considered as a treatment option. Fewer surgical operations, reduced treatment time, and optimal availability of existing bone are obvious advantages of the method; however, when applied in the continuous maxillary anterior region, inter-implant distance must be carefully considered, as well as accurate diagnosis and treatment planning for predictable outcome. In this case report, immediate placement of two implants in the continuous maxillary anterior along with bone graft following the extraction of root rests, and the restoration of provisional and implant-supported fixed prosthesis on a 63-year-old patient had resulted in both esthetically and functionally satisfactory clinical outcomes.

Gradual teeth wear is normal physiological progress, severe tooth wear can causes dysfunction, occlusal plane disharmony and esthetic problems. If additional space is needed for prosthetic restoration due to severe attrition, full mouth rehabilitation with increase of occlusal vertical dimension may be considered. In this case, 72 year old male patient with severe worn dentition, irregular gingival zenith and deep anterior bite was treated by full mouth rehabilitation for regaining the space for restoration, improving relationship and esthetic of anterior teeth. Provisional restoration obtained by systemic analysis, diagnosis and re-evaluation for a sufficient time was replicated to final restorations through double scanning technique using monolithic zirconia blocks. Satisfactory functional and esthetic outcomes were obtained.
