Traditional removable partial denture is a successful treatment for partial edentulous patients. When the abutment is formed with unilateral minority teeth, satisfaction with the use of removable partial denture may be lowered due to patient's discomfort and damage of the abutment. Recently, it has been reported that the unilateral posterior extension partial denture is used as a bilateral posterior extension partial denture using implant fixed prostheses as abutments. In this case, by using implant surveyed crown prostheses, bilateral posterior extension partial denture is fabricated in site that is predicted to have a poor prognosis. This resulted in improved support, maintenance, and stabilization of the removable partial denture, which were economically beneficial to patient and satisfied with use.

Fall is the most common cause of trauma in the elderly and a major reason of dental injury. Maxillary anterior region is the most vulnerable area to the traumatic fall. Loss of teeth and adjacent tissue in this area results in maxillofacial defects and inappropriate maxillomandibular relationship. Reconstruction of the loss requires comprehensive and careful planning to fulfill not only functional but also esthetic demand. Prosthetic approach can avoid surgically extensive intervention, reducing both treatment cost and time. This clinical report describes a 78-year-old woman with the loss of teeth and alveolar bone in maxillary anterior region due to a traumatic fall, rehabilitated with a metal-ceramic fixed dental prosthesis using gingival porcelain.

Dental trauma is common in active children and adolescents. Among them, in the case of ankylosis due to avulsion, diagnosis through clinical examination is important, and the treatment is important for esthetic prosthetic restoration after adulthood. This case is a case of esthetic prosthetic restoration of maxillary anterior teeth through decoronation and implant. After that, space was maintained for prosthetic restoration using a decoronated crown. After becoming an adult, precise implant placement and esthetic prosthetic restoration were possible using guide surgery. For soft tissue support, the temporary crown were replaced by changing the contours of the temporary crown, and the final esthetic prosthesis was fabricated by digital wax-up.

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.

In order to treat edentulous patients with fixed implant prosthesis, the final prosthesis form should be predetermined based on the anatomic structures of the arch, the opposing dentition, and the occlusal plane. The design and occlusion of the interim prosthesis can provide useful information when fabricating the definitive prosthesis. In this case report, scan data of the edentulous region and the interim prosthesis were superimposed through an intraoral scanning digital workflow. In this way, the interim prosthesis information was incorporated into the design of the final prosthesis. Furthermore, the interim prosthesis data acquired through intraoral scanning was utilized to plan the positions and angles of the implants based on the final prosthesis design. Surgical guides were used to accurately place the implants in the planned three-dimensional positions. In this case report, satisfactory esthetic and functional clinical outcomes were achieved through application of digital techniques.

Purpose: This study was to assess clinically the success rates and technical complications of cement-retained implant-supported single crowns and splinted crowns with zirconia frameworks. Materials and methods: 75 (single crowns: 51, splinted crowns: 24) cement-retained implant-supported single crowns and splinted crowns with zirconia frameworks which were restored in 67 patients were investigated for the evaluation of the success rates and technical complications. All restorations were cemented with temporary cement. Age, gender, restoration position, opposing teeth, restoration type were assessed as possible factors affecting technical complications. Results: During the mean observation period of 22.2 months, cumulative success rates of all restorations were 66.9 (73.2 - 60.6)%. Retention loss was found in 16 restorations (single crowns: 14, splinted crowns: 2), abutment screw loosening and veneer porcelain fracture were found in each 2 single crowns, respectively. According to a Kaplan-Meier survival analysis of single crowns and splinted crowns, the cumulative success rates were 58.9 (66.6 - 51.2)%, 87.5 (96.1 - 78.9)%, respectively. There was a statistically significant difference. The other possible factors did not have a significant effect on the technical complications. Conclusion: Retention loss was the most frequent technical complication. Abutment screw loosening and veneer porcelain fracture were found rarely in single crowns only. Age, gender, restoration position, and antagonist did not have significant effect on the technical complications. Splinted crowns had a higher success rate than single crowns.

For a full-mouth fixed prosthetic treatment of the edentulous patient, it is essential to confirm the proper tooth position and thorough evaluation of the remaining alveolar bone and soft tissue before surgery. CAD-CAM dentistry and guided implant surgery have such advantages of providing simultaneous planning of surgery and prosthetic treatment to ensure pre-knowledge of the treatment. In this clinical case, using the digital technology, digital temporary denture fabrication, esthetic evaluation before fixed prostheses treatment, and guided surgery planning was possible. After the surgery, previously obtained data was used for fabricating fixed temporary prostheses. Definitive zirconia prostheses transferred from the provisional prostheses were fabricated and functionally and esthetically satisfying results were obtained.

The progressive wear of teeth is a physiologic process of aging, but excessive wear can lead to occlusal disharmony, tooth sensitivity and pulp exposure, decreased masticatory efficiency, and aesthetic problems. It should be treated by evaluating the cause of tooth wear and establishing a stable centric relation with appropriate vertical dimension of occlusion and occlusal plane. The present case report successfully rehabilitated a full-mouth case of a severely worn dentition with the use of digital facebow transfer and virtual articulator.

There are various treatment options such as conventional complete denture, hybrid prosthesis and implant-supported fixed prosthesis for fully edentulous patients. In case of implant-supported fixed prosthesis, compared to removable prosthesis, it is difficult to place the implant in the correct position considering the anatomical contours of the final prosthesis. In this case, a full mouth rehabilitation with implant-supported fixed prosthesis was performed for a patient who required extraction of all remaining teeth due to dental caries and chronic periodontitis. In the implant placement stage, the implant was placed in the desired position using a surgical guide fabricated considering the anatomical contours of the final prosthesis, and the function and esthetics were evaluated through correction and re-fabrication of the fixed provisional restoration. A final restoration of porcelain fused to gold prosthesis was delivered to the patient based on the provisional restoration. To cope with complications such as loosening of screws and fracture of porcelain, a screw-retained type prosthesis was fabricated for the posterior part and a screw-cement-retained type prosthesis for the anterior part. As a result, the patient showed an improved prognosis in terms of functional and esthetics after the final prosthesis was delivered.
