Comparison of Attachment Types in Maxillary Implant-assisted Obturators using Digital Image Correlation Analysis.

Aim: The purpose of the study was to evaluate the stress on the implant and to assess the denture displacement for locator and bar and clip attachment types in implant-assisted obturators.

Materials And Methods: A maxillary edentulous experimental model with a maxillectomy defect was made along with an opposing edentulous mandibular model with self-cure acrylic. Two endosseous implants were placed in the maxillary model.

Analysis of factors determining thermal changes at osteotomy site in dental implant placement - An study.

Background: Heat generation during osteotomy site preparation is a crucial factor that determines the success of dental implant placement. Among the factors that affect the heat generation, drilling speed, hand pressure and coolant temperature are independent variables. However, a relation between these three parameters and their optimal values required for the maximum outcome has not been studied so far.

Effect of chemical disinfectants and accelerated aging on maxillofacial silicone elastomers: An Study.

Context: Maxillofacial prostheses need frequent refabrication due to degradation of color and deterioration of physical properties of the elastomer.

Aims: This study attempted to evaluate the change in color stability, Shore A hardness, and surface roughness of two maxillofacial silicones, A-2186 and Cosmesil M511, when submitted to chemical disinfection and accelerated aging.

Settings And Design: This was a comparative in vitro study.
