The purpose of this study was to report a rare case an aggressive nasopalatine cyst with nasal involvement in edentulous patient. A 61-year-old Caucasian male presented anterior maxillary lesion that prevented him from wearing his complete upper denture. Clinical examination showed vestibular and palatal swelling around the sites teeth #11, 12 13. Radiological revealed well-limited maxilla natu...

Objective This study investigated the wear resistance of injection-molded thermoplastic denture base resins using nanoindentation instrument. Materials and methods Six injection-molded thermoplastic denture base resins (two polyamides, two polyesters, one polycarbonate, one polymethylmethacrylate [PMMA]) and a PMMA conventional heat-polymerized denture-based polymer control were tested. Elastic...

Simple excision of the epulis fissuratum results in loss of sulcus dept hand scar formation, hence the peripheral seal of full denture are obstructed. In order to avoid these condition, lyophilized porcine skin or dermis were used to excised surface for wound dressing, and treatment dentures were inserted one week after the operation which act as a splint maintaining sulcus depth. Furthermore, ...

The central giant cell granuloma (CGCG) is benign, nonodontogenic, and intraosseous lesion of the jaw. Aggressive subtypes of CGCG have a tendency to recur after excision and require wide resection that leads to major defects in the jaw. In this case report a patient who had severe mandibular bony deficiency as a result of excision of aggressive CGCG, orthodontic, and prosthetic treatment was d...

The purpose of this study was to evaluate the fabrication of a complete denture using a CAD/CAM system. Cone beam CT was used to measure the complete denture and the artificial teeth. After a 3D complete denture image was structured using 3D CAD software, we factored out the artificial teeth and obtained a 3D denture base image. A machining center cut an acrylic resin block, and fabricated an a...

Inflammatory fibrous hyperplasia (epulis fissuratum) (IFH) and inflammatory papillary hyperplasia (IPH) are oral mucosal diseases caused by ill-fitting denture wearing. A study was carried out on a group of Turkish people consisted of 131 female and 39 male complete denture wearers (n= 170) distributed in two age groups (30-60 and 60-80 years old). The analysis of data collected from patients s...
