Photoelastic analysis of fixed partial prosthesis crown height and implant length on distribution of stress in two dental implant systems.

The aim of this study was to evaluate by photoelastic analysis stress distribution on short and long implants of two dental implant systems with 2-unit implant-supported fixed partial prostheses of 8 mm and 13 mm heights. Sixteen photoelastic models were divided into 4 groups: I: long implant (5 × 11 mm) (Neodent), II: long implant (5 × 11 mm) (Bicon), III: short implant (5 × 6 mm) (Neodent), and IV: short implants (5 × 6 mm) (Bicon). The models were positioned in a circular polariscope associated with a cell load and static axial (0.

Accuracy of enhancement filters in measuring in vitro peri-implant bone level.

Objectives: To identify the accuracy of enhancement filters of an intraoral phosphor-plate system for measuring the simulated peri-implant bone level.

Materials And Methods: A total of 20 titanium implants (Titamax(®) ) were placed into six fragments of bovine ribs and defects simulating bone loss were created. Periapical radiographs were taken with a phosphor-plate system (Vista Scan(®) ) according to the paralleling standard technique, and nine enhancement filters were applied: fine, caries 1, caries 2, perio, endo, noise reduction, invert, emboss, and sculpture.

Cervicofacial pain associated with Eagle's syndrome misdiagnosed as trigeminal neuralgia.

Background: Eagle's syndrome is characterized by the symptoms of recurrent throat pain, pharyngeal foreign body sensation, dysphagia, referred otalgia, and neck pain. The treatment for Eagle's syndrome can be pharmacologically, surgically, or both. The surgical management consists of two major procedures: the transoral approach or the extraoral-cervical approach.
