The prosthesis successfully reduced the incidence of cheek biting and improved the patient’s oral competency. This report describes the procedure for making an intraoral cheek bumper prosthesis to improve patient oral function. “
“This clinical report outlines a method to retrieve a fractured implant abutment screw through the use of high-power magnification and ultrasonic instrumentation. Furthermore, the use of manufacturer’s specific components is highlighted to minimize occurrences of such clinical complications from arising. “
“Prosthetic rehabilitation of acquired maxillary defects can be achieved satisfactorily if all

facets of treatment planning and design considerations are taken into

account before find more the rehabilitation process. Complications associated with maxillary defects limit treatment protocols to a great Dasatinib chemical structure extent. The prosthodontist has to identify these problem areas and suitably devise feasible options and incorporate them in the design. In this report, an acquired maxillary defect with unfavorable undercuts in the defect was successfully treated by making a two-piece sectional obturator. The two pieces were connected by the use of double-die pin system. The methodology greatly reduced chairside time and number of visits, and effective obturation was satisfactorily achieved. “
“Purpose: To evaluate stress distribution in different horizontal mandibular arch formats restored by protocol-type prostheses using three-dimensional finite element analysis (3D-FEA). Materials and Methods: A representative model (M) of a completely edentulous mandible restored with a prefabricated bar using four interforaminal implants was created using SolidWorks 2010 software (Inovart, São Paulo, Brazil) and analyzed by Ansys selleck kinase inhibitor Workbench 10.0 (Swanson Analysis Inc., Houston,

PA) to obtain the stress fields. Three mandibular arch sizes were considered for analysis, regular (M), small (MS), and large (ML). Three unilateral posterior loads (L) (150 N) were used: perpendicular to the prefabricated bar (L1); 30° oblique in a buccolingual direction (L2); 30° oblique in a lingual-buccal direction (L3). The maximum and minimum principal stresses (σmax, σmin), the equivalent von Mises (σvM), and the maximum principal strain (σmax) were obtained for type I (M.I) and type II (M.II) cortical bones. Results: Tensile stress was more evident than compression stress in type I and II bone; however, type II bone showed lower stress values. The L2 condition showed highest values for all parameters (σvM, σmax, σmin, ɛmax). The σvM was highest for the large and small mandibular arches. Conclusion: The large arch model had a higher influence on σmax values than did the other formats, mainly for type I bone. Vertical and buccolingual loads showed considerable influence on both σmax and σmin stresses.
