Tooth wear is a physiologic process, but when accelerated by specific factors, it is considered pathologic wear, leading various issues that require prosthodontic intervention. Full-mouth prosthetic rehabilitation is often considered to restore adequate vertical dimension and esthetics for patients with severely worn dentition.However, a minimally invasive prosthodontic approach through multidisciplinary collaboration may be feasible for patients with localized anterior or posterior wear. This clinical case addressed the treatment for excessive anterior deep bites and pathologic wear of the anterior teeth, leading to deteriorated esthetics and function. Orthodontic extrusion was employed in the posterior teeth to increase the vertical dimension of occlusion and secure adequate space for the anterior restorations. A minimally invasive treatment was possible by limiting the scope of treatment to the anterior region. As a result, function and esthetics were improved by restoring only the teeth with pathologic wear without removing healthy tooth structure.

Restoring lost teeth is very important in terms of both function and aesthetics. If tooth loss occurs in the posterior region and the loss of support is persistent, it may cause a gradual shift in the position of the mandible and a change in occlusion. This clinical case attempted to restore support for the posterior teeth with a fixed prosthesis using implants in a patient whose opposing teeth were erupted and the occlusal plane collapsed due to long-term loss of the maxillary left posterior teeth and mandibular right first molars. To correct the occlusal plane of remaining dentition, wax-up of maxillary left posterior teeth was duplicated with acrylic resin and placed on maxilla. Surgical template for implant placement were fabricated using digital technology. After the support of the posterior teeth was restored with the placement of the implant, stable occlusion with temporary restorations was observed for a sufficient time. Afterwards, monolithic zirconia prosthesis was placed on the patient to ensure functional and aesthetic improvement.

A variety of digital technologies are being used throughout the entire implant treatment process of diagnosis, surgery, impression, design, and fabrication of prostheses. In this case, using a digital surgical guide, sinus floor elevation was performed without complications, and the implants were placed in the planned position. After the healing period for osseointegration, CAD-CAM (Computer-aided design-Computer-aided manufacturing) customized abutments and provisional prostheses were delivered. While using the provisional prosthesis, occlusal change was observed. To transfer the intermaxillary relationship and abutment position that reflect occlusal change and axial displacement, double scanning and abutment-level digital impressions were taken. Abutment superimposition was used to capture the subgingival margin without gingival retraction. Then, the definitive prosthesis was designed and fabricated with digital system. We report a case applying digital system, to achieve the predictable result as well as the efficient treatment process from implant surgery to fabricating prosthesis in the posterior area.

There are various approaches to treatment for patients with fully edentulous jaw. In maxilla, it is easy to obtain sufficient stability, support, and retention with the traditional full denture method. In mandible, however, there are difficulties caused by anatomical limitations. In this case, treatment with implants can be considered. If it is difficult to place implants in posterior area, a fixed complete denture can be considered, using 4 - 5 implants anterior to mental foramen. This approach has changed in many ways, such as surgical methods and materials used, over the years. This case report compares two approaches and their changes over time, especially in the cases of mandibular fixed prostheses using implants, paired with maxillary complete denture.

For fully edentulous patients, implant-supported overdenture can be considered to enhance chewing efficiency and denture stability. Implant planning software can be used to fabricate a surgical guide for a more precise consideration of anatomic factors and prediction of the shape of definitive prosthesis. Though there are many possible attachments for implant overdenture, milled bar can be useful due to its splinting effect of implants and rigid support of overdenture. This report presents a case of implant-supported milled bar overdenture after guided implant surgery performed with two surgical guide that was fabricated before and after bone reduction.

A crossed occlusion resulting from the presence of posterior teeth in one arch but no opposing teeth in the opposite arch results in collapse of the vertical dimension. In this case, the patient has a class III malocclusion with crossed occlusion and anterior crossbite. In order to evaluate the proper vertical dimension, provisional denture was used to stabilize the vertical occlusal dimension for 3 months. After, provisional fixed restoration was used for the stabilizing occlusal relationship and aesthetic improvement for lip support. Definitive prosthesis in implants in the mandible and abutments in the maxillary were using Porcelain-fused-to-metal crown (PFM) crown and the maxillary unilateral edentulous area was treated with removable partial dentures. Through this, proper support of the posterior region and normal anterior occlusal relationship were formed, and the patient was able to obtain aesthetically and functionally satisfactory treatment results.
