Clinical remounting of complete denture is performed to refine occlusal harmony in maxillo-mandibular relation. It has been reported that patients who used adjusted dentures with clinical remounting felt less complications such as pain and discomfort in mastication. The purpose of this study was to assess effects of clinical remounting with case series. Seven patients with existing complete prosthesis were included. Clinical remounting procedure was done through interocclusal relation recording. In addition, occlusal force was measured with pressure indicating sensor and occlusal contact areas were evaluated with photo occlusion analysis. Occlusal contact areas of prosthesis were enlarged, while bite pressure was not increased. Hit and slide phenomenon of prosthesis was reduced concurrently. Clinical remounting procedure improved denture stability and increased occlusal contact area. Therefore, clinical remounting should be considered.

Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the final prosthesis. These occlusal errors can be corrected in two ways: i) in patient's mouth ii) by recording new centric relation and remounting dentures on an articulator. The latter method is more feasible because the mobility of denture base on the mucosa in oral cavity does not permit the identification of premature contacts in centric occlusion and tooth guided eccentric excursions. This article describes a modest and effective clinical chair-side remount procedure using customized mounting platforms.

This clinical report presents the case using overlay dentures to treat a patient with cleft lip and palate and malocclusion. This patient requires vigorous treatment such as orthodontic treatment and combined orthodontic/oral surgery procedures. Overlay denture can be used as an alternative treatment option. Intraoral and radiographic examinations were done. The vertical dimension of occlusion was evaluated for proper prosthetic procedures and the surveying in the diagnostic cast was done. Considering the tissue and teeth undercut, the alterations of teeth shape were done. Final preparation and impression was performed. After the evaluation of vertical dimension and occlusion with wax-denture, the dentures were polymerized. Clinical remounting and occlusal adjustment were done on the articulator. Overlay dentures were delivered and the patient was recalled for relining. The overlay dentures satisfied patient's esthetic and functional requirements and provided a stable occlusion. Overlay dentures in this case were a reversible and relatively inexpensive treatment for this patient, however the potential possibilities of caries and periodontal disease as a result of poor oral hygiene should be prevented with periodic recall.

Loss of posterior support may cause overloading and excessive wear of remaining teeth. Moreover, the extrusion of antagonistic teeth leads to the destruction of the occlusal plane. The loss of vertical dimension of occlusion (VDO) also emerges clinically, which may bring the loss of esthetic appearance and function. These patients who suffer from the loss of posterior support, often require vigorous periodontal treatments (osteotomy, crown lengthening) and extensive oral rehabilitation. Sixty three years old female patient visited for the prosthetic treatment of the posterior edentulous area. She had no other systematic disease and parafuctional habits for prosthetic treatment. Intraoral and radiographic examinations were done. The evaluation of VDO and vertical dimension of rest position were evaluated for proper prosthetic procedures and diagnostic wax up was done. As a result of diagnosis, VDO was increased by 2 mm considering the loss of VDO and space for the prosthetic treatment. After the pretreatments, initial preparation of teeth and provisionalization were carried out. Six weeks later of provisionalizaion, final preparation and impression was performed. Using the duralay resin copings, jaw relation was registered. The master cast was mounted and definitive restoration was fabricated. After the evaluation of esthetic and function, pick up impression for clinical remounting was done. Lucia jig was made for new jaw relation and occlusal adjustment on the articulator. Definitive restoration was delivered and the patient was periodically recalled for additional occlusal adjustment. From this case, the satisfactory functional and esthetic results through full mouth rehabilitation with increase vertical dimension were achieved.

Nowadays, CAD/CAM is broadly used in dentistry for inlays, crowns, implant abutments and its spectrum is expanding to complete dentures. Utilizing CAD/CAM to fabricate complete dentures is expected to decrease chair time and the number of visits, thus decreasing total fabrication time, expenses and errors caused during fabrication processes. One of the systems using CAD/CAM, DENTCA$^{TM}$ CAD/CAM denture (DENTCA Inc. Los Angeles, USA) scans edentulous impressions, designs dentures digitally, fabricates try-in dentures by 3D printing and converts them into final dentures. Patients can wear final dentures after only 2 - 3 visits with satisfying adaptation. This case report introduces a 71-year-old male patient who visited to consult remaking of existing old dentures. Residual teeth with bad prognosis and root remnants were extracted and the patient used reformed existing mandibular denture for 2 months. And then DENTCA system started. One-step border molding was done using conventional tray of adequate size provided by DENTCA system and wash impression was taken. Gothic arch tracing was completed based on the vertical dimension of existing dentures. Both maxillary and mandibular trays were placed to the resultant centric relation and bite registration was taken. Then DENTCA scanned the bite registration, arranged the teeth, completed the festooning and fabricated the try-in dentures by 3D printing. The try-in dentures were positioned, occlusal plane and occlusal relations were evaluated. The try-in dentures were converted to final dentures. To create bilateral balanced occlusion, occlusal adjustment was done after clinical remounting using facebow transfer. The result was satisfactory and it was confirmed by patient and operator.
