Pathologic attrition leads to pathologic damage on occlusal plane, functional disorders, occlusal disharmony, esthetic problems, pulpal lesion, temporomandibular joint (TMJ) disorder. In this case, treatment plan should be considered for possibility of vertical dimension loss, occlusal pattern, esthetics, phonetics, amount of vertical dimension increase. This case report was a 71-year-old man who had severely worn dentition. Full mouth rehabilitation was carried out with vertical dimension increase due to limited space for prosthesis. After evaluation of provisional restorations for patient's compliance, final restorations were fabricated and routine clinical assessments were made. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition.

The progressive attrition of teeth is a normal process by aging. However, excessive tooth wear with decreased vertical dimension of occlusion and collapse of occlusal plane may cause pathologic pulpal condition, occlusal disharmony and functional disorders. In this case, a patient with severely worn dentition was treated. Diagnostic wax-up was performed at the increased vertical dimension. After evaluation of provisional restorations for 12 weeks, final restorations were fabricated with zirconia crown and routine clinical assessments were made. Esthetically and functionally satisfactory results were obtained.

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.

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.

In a edentulous patient, various methods can be employed for prosthetic treatment using implants, such as implant-supported fixed prostheses, overdentures, hybrid prostheses, and implant assisted removable partial denture. In this case, in a patient with moderate to severe chronic periodontitis requiring full arch extractions, implants were strategically placed using computer-guided surgery. In the maxilla, due to inadequate bone quality and quantity leading to insufficient initial stability, delayed loading was implemented, and interim prosthesis was used during the osseointegration period. In the mandible, stable initial stability was achieved, allowing for immediate loading to reduce patient discomfort. Primary stability is considered the most crucial factor for obtaining immediate loading, so a thorough clinical and radiological evaluation of the remaining alveolar bone quantity and quality must be conducted before surgery.

In patients with newly established ideal occlusion through full-mouth rehabilitation using fixed prostheses, complications and occlusal changes over time can arise because of various factors. This case report describes a 10-year follow-up of a patient with masticatory dysfunction and aesthetic problems who underwent full-mouth rehabilitation with an increased vertical dimension. During the follow-up, complications such as tooth fracture, occlusal changes, infraocclusion of few implant-supported prostheses, and loss of interproximal contacts were observed. Detecting these issues early through periodic follow-up is important. This case report aims to review the causes of complications after full-mouth rehabilitation using fixed prostheses and the strategies for their management.

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.

As patients' esthetic expectations increase, there is an increase in demand for cosmetic restorations of anterior and posterior teeth that resemble the natural tooth morphology and color. An example of high-strength all-ceramic systems is zirconia with CAD/CAM application. This case report describes a full-mouth rehabilitation using zirconia all-ceramic crowns supported by upper and lower implants and by a minimal increase in the occlusal vertical dimension in a patient with severe abrasion due to loss of posterior teeth.

Using computer-aided design and manufacturing technique improve quality of treatment in many aspect. This case reports the complete mouth rehabilitation of a patient with amelogenesis imperfecta utilizing digital technology. Clinical examination revealed loss of mastication due to insufficient occlusal stop, missing teeth, interdental spacing due to microdontia, insufficient overbite, and etc. Full veneer crowns for teeth were selected, followed by a fixed partial denture and implant placement was done using CAD-CAM guide template with bone graft for partially edentulous space. Definitive restorations were duplicated by double scanning provisional restorations and successfully delivered to the patient. These full mouth rehabilitation procedures resulted in satisfactory outcomes for the patient functionally and aesthetically.

With the development of digital dentistry, it is being applied in various ways of dental treatment. This case report presents the definitive prosthesis designed in advance with a re-established vertical dimension and the digital technology, which determined the amount of tooth preparation, in order to preserve as much tooth structure as possible in a patient with pathological wear of the posterior teeth and loss of vertical dimension. For accurate tooth preparation, the guides of the occlusal and axial surfaces were digitally and additively manufactured. Then, aesthetics and anterior guidance were established at the provisional stage. The information of the provisional restoration was delivered to the definitive stage by double scanning. The digital technology, including the virtual planning and the guided tooth removal, produced the definitive restorations satisfactory to both the patient and clinician.
