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.

Prosthetic treatment using implants in fully edentulous patients includes implant-supported fixed prosthesis, implant hybrid prosthesis, implant retained- or supported-over-denture and implant supported fixed prosthesis has advantages such as psychological stability, pronunciation. If an implant supported fixed prosthesis is planned, the implants should be placed in consideration of pronunciation, esthetics, and oral hygiene. For this, clinical and radiological diagnosis is indispensable. When placing the prosthetic driven implant at the site determined from the diagnosis, a sufficient amount of alveolar bone and soft tissue support are required. If these requirements found to be insufficient, a wide range of bone grafting should be performed in advance. In this case, a fully edentulous patient with severe alveolar bone resorption due to periodontal disease was treated with a full mouth rehabilitation using implant-supported fixed prosthesis preceding maxillary sinus graft and alveolar bone augmentation. We report this patient were satisfied with esthetic and function.

Full-mouth reconstruction of a patient using dental implants is a challenge if there is vertical and horizontal bone resorption. Therefore, it is should be cautious in making the fixed prostheses that restore the function and the esthetics of the gingiva and teeth. In full mouth rehabilitation, CAD/CAM system makes it possible to fabricate restorations with high precision, regardless of span of the restoration. Recently, Palladium-silver (Pd-Ag) alloy which is highly biocompatible and millingable has been developed to compensate for the shortcomings of the titanium or zirconia. This clinical report presents the reconstruction of a maxillary arch with a cement retained implant supported fixed prosthesis using a Pd-Ag alloy generated by CAD/CAM system on eleven osseointegrated implants. The occluding surfaces were made of Pd-Ag alloy, to decrease the risk of chipping or fracture. The prostheses were esthetically pleasing, and no clinical complications have been reported after two years.

A patient with severe periodontitis has causative factors that cause pathological tooth movement, the occlusion is disintegrated, and the vicious cycle of worsening periodontitis is repeated. In particular, when pathological tooth movement occurs in the maxillary anterior region, the patient has an aesthetic sense of atrophy, and the quality of life was reduced. Therefore, when orthodontic treatment was added to patients with severe periodontitis, it promotes the formation of new bone, reduces periodontal cysts, and obtains clinical attachment, which leads to favorable results in prosthetic restoration, thereby enabling ideal occlusion, function and aesthetics. Periodontal treatment, orthodontic treatment, natural tooth restoration, and implant prosthesis were planned for patients with pathological tooth movement in the anterior region due to loss of occlusal support in the posterior region. As a result, an ideal restoration space was secured, a stable restoration of occlusal contact was formed, and the maxillary anterior teeth were aesthetically improved.

The most critical aspect of full-arch prosthodontic treatment is evaluating whether the patient's vertical occlusal dimension is appropriate, and if necessary, restoring it through increasing vertical dimension. If the vertical occlusal dimension is too low, it can lead to reduced chewing efficiency, as well as not only aesthetic concerns but also potential issues like hyperactivity of muscles and posterior displacement of the mandible. This report is about the patient dissatisfied with pronunciation and aesthetics due to an inappropriate vertical occlusal dimension resulting from prior prosthetic interventions, underwent full-arch prosthodontic restoration treatment. Through the utilization of digital diagnostic apparatus, a comprehensive evaluation was undertaken for patient's vertical occlusal dimension, occlusal plane orientation, and the condition of prosthetic restorations. Through 3D facial scanning, the facial landmarks were discerned, and subsequently, the new occlusal plane was established. This provided the foundation for a digitally guided diagnostic wax-up. An elevation of 5 mm from the incisor was determined. Comprehensive dental rehabilitation was then executed for all remaining teeth, excluding the maxillary four incisors. The treatment protocol followed a systematic approach by initially creating implant-supported restorations on both sides of the dental arch to establish a stable occlusal contact. Subsequently, prosthetic restorations for the natural dentition were generated. Diagnostic and treatment planning were established through the utilization of facial scanning. This subsequently led to a reduction in treatment complexity and an expedited treatment timeline.

Amelogenesis imperfecta characterized as abnormally formed enamel is caused by a defect of unique group of genes. Patients affected by this disease might have difficulties in social and psychological aspects due to non-esthetic teeth as well as functional problems caused by enamel detachment and tooth wear from their early ages. Adult patients with amelogenesis imperfecta can be treated with full-mouth restorations, which make functional and esthetic rehabilitations of severely worn tooth. However, the anterior open bite and lack of occlusal clearance for posterior teeth restorations due to compensatory extrusion are the intervening factors in the prosthetic treatment. Therefore, the determination of anterior tooth lengths, vertical dimension, and anterior guidance should be set carefully. Recently, computer-aided design and computer-aided manufacturing (CAD/CAM) techniques help systematic approaches and enable dentists to reduce time-consuming procedures in the diagnosis and treatment of full-mouth rehabilitation. This case report demonstrates the successful full mouth rehabilitation using a CAD/CAM system in a young adult patient with amelogenesis imperfecta and anterior open bite.

Severe tooth wear may lead to pathological changes of pulp, imbalance in occlusion as well as functional and esthetic problems. In this case, 34-year-old male came to the hospital because of generally worn dentition due to attrition and erosion. After evaluation, a full mouth restoration with elevation of the vertical dimension of occlusion was planned. After occlusion was stabilized by an occlusal stabilization appliance, centric relation position was recorded and subsequent provisional restorations were fabricated. After evaluation, a CAD-CAM (computer aided design-computer aided manufacturing) prosthetic restoration was carried out using monolithic zirconia. After 12 months of follow up observation, the patient was satisfied with function and esthetic appearance.

This clinical report focuses on the treatment of a patient with esthetic and functional impairments due to severe worn dentition. Absence of posterior support for a prolonged period require comprehensive prosthetic restoration. Accurate clinical and radiographic examinations, diagnostic wax-up, and occlusal vertical dimension evaluation were performed and the degree of patient adaptability was evaluated using an interim restoration. After 8 weeks of stabilization with interim restoration and confirmation of absence of any abnormal findings, definitive prostheses were fabricated. Satisfactory functional and esthetic outcomes were observed after 6 months of follow-up.

Loss of teeth may not only imply impaired oral function and loss of alveolar bone but is also often accompanied by reduced self-confidence. This results in a larger problem with the fully edentulous patient. The patient introduced in this study showed multiple missing teeth and mobility of remaining teeth and wanted to have fixed dental prosthesis using implants. Remaining teeth were extracted because of periodontally bad prognosis. This article reports a satisfactory clinical and esthetic outcome of full mouth rehabilitation using implant hybrid prosthesis in fully edentulous patient.
