A patient with para-functional habits can cause widespread teeth wear, along with temporomandibular joint disorders and myofascial pain syndrome in the masticatory muscles. Prolonged teeth wear is associated with a decrease in vertical occlusal dimension, leading to issues such as changes in facial morphology, decreased masticatory efficiency, and temporomandibular joint disorders. To achieve a three-dimensional full-mouth rehabilitation in patients with decreased vertical occlusal dimension, accurate diagnosis, analysis, and proactive treatment planning are essential. Prosthetic treatment accompanied by the restoration of physiological vertical occlusal dimension and the re-establishment of a normal occlusal plane is necessary. This case report presents a full-mouth rehabilitation case involving a patient with overall teeth wear, showing decreased vertical occlusal dimension which results in discomfort in the temporomandibular joint and aesthetic dissatisfaction. The report highlights the successful outcome achieved through the use of occlusal stabilization splint for temporomandibular joint stability and Gothic arch tracing devices for the re-establishment of intermaxillary relationships. Also, through adjustments and adaptation assessment using provisional prostheses, favorable outcomes were achieved both functionally and aesthetically.

Deep overbite patients who do not have proper occlusal relationship may cause problems such as teeth wear and antagonist extrusion. These lead to the collapse of occlusal plane and esthetic problem. Increasing vertical dimension is frequently essential to resolve those problems. This case report demonstrates a full-mouth rehabilitation for a patient with severe deep bite that contacts surface to surface by increasing vertical dimension. Treatment procedures included diagnosis, treatment planning, implant surgery, and prosthodontic rehabilitation. Satisfactory results were obtained in functional and esthetic aspects.

In patients with unstable mandibular movements who are accompanied by involuntary facial muscle movements and asymmetrical changes in the facial features, many difficulties exist in determining the vertical dimension of occlusion, recording centric relation, and transferring information about the occlusal plane. In this case, for a patient with unilateral facial nerve palsy who was edentulous for a long period of time, a CAD-CAM provisional prosthesis was fabricated using a 3D printing customized gothic arch tracer and a prefabricated occlusal plane recorder, the POP bow system, to achieve a stable interarch relationship. Afterwards, a full mouth implant fixed prosthesis was fabricated by delivering an appropriate vertical dimension of occlusion, a reproducible centric relation, and a correct three-dimensional occlusal plane, and continuous maintenance was performed to restore functional and aesthetic oral health to the patient.

Gradual teeth wear is normal physiological progress, severe tooth wear can causes dysfunction, occlusal plane disharmony and esthetic problems. If additional space is needed for prosthetic restoration due to severe attrition, full mouth rehabilitation with increase of occlusal vertical dimension may be considered. In this case, 72 year old male patient with severe worn dentition, irregular gingival zenith and deep anterior bite was treated by full mouth rehabilitation for regaining the space for restoration, improving relationship and esthetic of anterior teeth. Provisional restoration obtained by systemic analysis, diagnosis and re-evaluation for a sufficient time was replicated to final restorations through double scanning technique using monolithic zirconia blocks. Satisfactory functional and esthetic outcomes were obtained.

Interim immediate denture is fabricated to minimize the period of edentulousness after removal of the patient's remaining teeth and before delivery of final prosthesis. In the case of using the CAD/CAM system, there is an advantage in that the manufacturing process in the clinic and laboratory can be simplified by overcoming some of the limitations of manufacturing interim immediate dentures in the traditional way. However, there are also disadvantages in that errors occur in the process of transmitting information about the patient's intermaxillary relationship to the digital network of the laboratory, resulting in unstable occlusal relationships or non-esthetic prostheses. To overcome this problem, using the simple and accurate POP BOW system's occlusal plane digital transfer method, it was possible to fabricate an esthetic and functional 3D printed interim immediate denture after removal of the remaining upper and lower anterior teeth.

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.

It is important to produce a provisional restoration reflecting the patient's jaw relation, occlusal plane, lip support, shape of teeth, and occlusion type for fully edentulous patients before making a definite prosthesis. The patient introduced in this study showed bad prognosis of remained tooth after severe periodontal diseases. Therefore, remaining teeth were extracted and replaced with dental implants. Provisional restorations were fabricated and the the patient's vertical and horizontal jaw relationship, occlusal plane, amount of overjet and overbite, size of teeth, and length of anterior tooth were recorded. Provisional restorations were scanned and CAD/CAM techniques were used to fabricate a monolithic zirconia bridge, which contour is identical with the provisional restorations. The patient was satisfied with the treatment results on functional, esthetic aspects and the prosthesis retained stable during the four-month clinical observation period.

Teeth wear and extrusion of antagonist are commonly observed in deep bite patient having severe vertical and horizontal overlap. These problems cause collapse of occlusal plane and abnormal anterior guidance. Without restoring harmonious occlusion, loss of multiple teeth and decreased masticatory function could not be prevented. To resolve problems associated with deep bite, multidisciplinary treatment including oral surgical, orthodontic and prosthetic treatment should be performed. This clinical report describes the results of increasing occlusal vertical dimension with a full-mouth restoration procedure. The treatment procedures include extraoral and intraoral examination, diagnosis, treatment planning, diagnostic wax-up, segmental osteotomy, orthodontic intrusion and prosthodontic rehabilitation. Full mouth rehabilitation with increasing occlusal vertical dimension can solve esthetic and functional problems.

The collapse of the posterior occlusion destroys the normal occlusal plane and causes excessive wear reducing the vertical dimension. Reduced vertical dimension of occlusion causes not only aesthetic and functional problems but also overloading on the temporomandibular joints and abnormalities of muscle nerve system. In order to improve the collapsed occlusal relationship, it is necessary to consider the change of the vertical dimension. It is necessary to make a precise diagnosis and analysis before the treatment and to evaluate the adaption of patient to the new vertical dimension of occlusion. A patient with excessive overbite often has occlusal problems of tooth wear and tooth eruption. Considering these considerations, overall prosthodontic restoration is required to solve the problem. A patient of 68 year old man in this case who suffered major tooth wear and maxillary posterior teeth loss was treated with elevation of vertical dimension of occlusion by maxillary removable dental prosthesis and mandibular fixed prosthesis.

A patient failed to use conventional complete dentures due to severe mandibular bone resorption and soft tissue hyperplasia on lips, tongue and oral vestibule from vascular malformation. The treatment of choice would be an implant-retained overdenture, however, he refused owing to high cost. The closed mouth impression technique using BPS principle, CR record registration with gothic arch tracing and monoplane occlusion using non-anatomic teeth were used to fabricate complete dentures for this patient. Patient satisfaction, the retention and the stability of complete dentures were highly improved as a result.
