The use of a removable partial prosthesis is an effective treatment modality in the reconstruction of large maxillary defects, because it provides adequate support for the soft tissue and improves facial contours. Oral functions, such as speech and swallowing, also benefi t from the use of removable partial prostheses. Osseointegrated implants are generally not indicated due to systemic factors...

background:  the metal  framework  of a removable partial denture includes various parts and metal components that supply strength, retention, stability ,  and support of partial denture.  the purpose of this study is assessing the quality of the frameworks made in  the  department of prosthodontics, qazvin school of  dentistry , regarding  their causes of malfunction,  retention, stability ,  ...

Kriesell proved that every almost critical graph of connectivity 2 nonisomorphic to a cycle has at least 2 removable ears of length greater than 2. We improve this lower bound on the number of removable ears. A necessary condition for critically 2-connected graphs in terms of a forbidden minor is obtained. Further, we investigate properties of a special class of critically 2-connected series-pa...

several appliances have been used for palatal expansion for treatment of posterior cross bite. the purpose of this study was to evaluate the stress induced in the apical and crestal alveolar bone and the pattern of tooth displacement following expansion via removable expansion plates or fixed-banded palatal expander using the finite element method (fem) analysis.two 3d fem models were designed ...

OBJECTIVE To describe vertical distraction osteogenesis of a scapular flap and removable lip support for oral rehabilitation after surgical creation of an ablative defect of the mandible. CASE REPORT A 70-year-old man who was diagnosed with squamous cell carcinoma of the left lower gingiva underwent segmental mandibulectomy for tumor ablation and reconstruction with a scapular bone flap. To a...

This report describes the use of a removable acrylic resin tray handle that can be easily attached to custom impression trays to produce an improved peripheral sealing zone. This device can be indicated to develop functional impressions for complete dentures using the patient-conducted muscular motion technique. In upper trays, the handle is fixed in the midline with acrylic resin, while in low...

This study explored a method for fabricating removable complete denture aided by CAD&RP technology. 3D crossing section scanner and laser scanner were respectively applied to obtain the surface data of artificial teeth, edentulous models and rims made in clinic. The vertical and horizontal relations of models were recorded before scanning with a special device. A 3D graphic database of artifici...
