The most important factor in the treatment of fully edentulous patients using implants is the shape of the definitive prosthesis. After the shape of the definitive prosthesis is determined, residual bone analysis and selection of the implant type, number and position should be followed. In this case, for restoration of an edentulous patient fully implanted (except the maxillary right lateral incisor) without considering definitive prosthesis, facial esthetics and possibility of fixed type prosthesis were evaluated using complete denture. It was determined that the fixed type prosthesis was possible. Implants that could not be used for the definitive prosthesis were excluded from the treatment plan and fixed type provisional restorations were fabricated. After four months of provisional restorations, the patient showed stable occlusion and esthetic satisfaction. Definitive prosthesis was made of zirconia using CAD/CAM (computer aided design and computer aided manufacturing). The results were satisfactory during the 3 months of follow-up period after termination of treatment.

Implant-Assisted Removable Partial Dentures (IARPDs) treatment is being performed in a fully edentulous patient using implant surveyed prosthesis as an abutment. Implant-supported prosthesis as an abutment of IARPDs is classified into screw-retained and cement-retained type according to the retention type, and each has advantages and disadvantages. The EZ crown system (Samwon DMP, Yangsan, Korea) has a cylinder combined with abutment, and the nickel-titanium spring in this cylinder provides a constant force on the zirconia ball to obtain retention in EZ crown system. In this patient, the natural abutment teeth of the mandibular overdenture was hopeless. We planned implant assisted removable partial denture using anterior implant surveyed prosthesis considering functional and esthetical rehabilitation, cost and patient's needs. When fabricating IARPDs using implant as abutment, we could compensate for the shortcomings of existing implant-supported prosthesis retention type and made the design of removable partial denture easy due to using EZ crown system.

Oral lichen planus (OLP) is a common mucocutaneous disease, which presents as bilateral or multiple lesions. The several factors are implicated in etiology of OLP such as dental restorations, systemic disease, drugs and stress. Especially the influence of dental restorations and plaque control for OLP has been the interest in dentistry. This case is about OLP patient having poor contoured and ill-fitting metal ceramic restorations. The patient in this study has suffered from OLP for a long time, particularly after restoration of metal ceramic restorations on both posterior teeth of maxilla and mandible. This study reported that OLP lesion recovered effectively by improving the contour and fitness of restorations with plaque control.

To obtain better esthetic results when immediately placing a dental implant, the soft tissue surrounding the implant must be conditioned during healing of the extraction socket. To this end, the emergence profile can be customized through immediate restoration of the provisional prosthesis, and good clinical results can be obtained at the time of definitive restoration in the future, resulting in high patient satisfaction. In this case, horizontal root fracture occurred after trauma to both maxillary central incisors. Immediate implant placement and loading was planned considering aesthetics and alveolar bone condition. By taking an impression using a digital intraoral scanner, a digital diagnostic wax-up was performed to make a more aesthetic prosthesis without applying external force to the traumatized teeth. Based on this, the ideal placement location was determined and immediate implant placement was performed using a 3D printed surgical guide. The provisional prosthesis was restored 5 days after placement, and the definitive zirconia crown was restored through soft tissue conditioning and customization using the shape of the provisional prosthesis for 3 months.

When fabricating definitive implant-supported fixed prostheses in upper and lower completely edentulous patients, it is crucial to get information about the vertical dimension, jaw relationship, implants, abutments and gingival contour. In this case, temporary prostheses were used to take the information. The temporary prosthesis was scanned outside of the mouth so that it increased the efficiency of scanning it. During the scan of the prosthesis, a scan zig which connected both posterior parts of the prosthesis was used to minimize the scan errors. We report this case because we obtained satisfactory functional and esthetic results by using the digital technology.

치아형태라고 하면 따분하고 재미없는 것으로 생각하기 쉽지만, 치과임상에서 아주 중요한 기초를 형성하고 있다. 지대치형성은 치과보철수복의 첫 단계로서, 좋은 지대치형성은 좋은 보철물로 연결된다. 또한 치과보철 수복의 대부분은 원래의 치아형태수복에 맞추어져 있어서, 치아형태와 지대치형성은 많은 상관성을 가지고 있을 것이라고 유추해 볼 수 있다. 그러나 통상적으로 알고 있는 치아형태는 교합변형태로만 인식하고 있어서, 지대치형성시 치아형태가 큰 도움을 주지는 못하는 실정에 있다. 물론 교합면형태도 중요하지만 그외의 여러형태도 치과임상에 있어서 결코 무시할 수 없다. 필자는 지대치형성에서 고려해야 할 치아형태와 임상적 중요성에 대해서 언급하여 치과의사선생님들의 임상에 도움을 주고자 한다.
