Provisional restorations are vital to fixed prosthodontics treatment, providing an important diagnostic function while in place. In addition to protecting the prepared teeth, provisionalization enables clinicians to refine biologic and biomechanical issues before the final restoration is fabricated. Adjustments can be made in the provisional restoration to achieve both the clinician's and patient's desired results. The fabrication of temporary restorations requires that clinicians be proficient with a variety of materials and techniques that can be used to make well-adapted and functional provisionals. There are many material choices available to temporize a single crown as well as multi-unit fixed partial dentures, and the selection of provisional materials should be made based on a case-by-case evaluation. This article provides a review of polymeric resin provisional materials.

Objectives: The objective of this study was to evaluate the long-term clinical outcomes of one-piece narrow-diameter implants (NDIs), with diameters of 2.5 mm and 3.0 mm, and to investigate the factors that affect marginal bone loss (MBL) around these implants.

Background: The correlation between the three-dimensional spatial representation (3DSR) abilities, specifically involving spatial orientation, spatial visualisation and spatial relationship, and the performance in exercises related to preclinical practical exams in fixed prosthodontics and removable partial denture is not studied.
Objective: Assess the correlation between the 3DSR abilities and the performance in exercises related to preclinical practical exams in fixed prosthodontics and removable partial denture carried out by second and third year dental students.
Materials And Methods: The 3DSR abilities (spatial orientation, spatial visualisation and spatial relationship) and the scores of preclinical practical exams in prosthetics were tested on 187 students.

An important step in the workflow for a complete arch fixed implant-supported prosthesis is the fabrication of a prototype resin prosthesis to allow the patient to visualize the definitive treatment outcome and also to use as an interim prosthesis. Producing a prototype prosthesis with the natural appearance of the gingival color and contour has been challenging. Current methods include painted stains, manually applied pink composite resin or autopolymerizing acrylic resin, and multicolored resin blocks, but these are all relatively expensive, have less than optimal esthetics, and are labor-intensive and time-consuming.

: The measurement of Hounsfield units (HU) during implant treatment planning is important. Currently, various manufacturers' implant planning software programs offer HU capabilities; however, their accuracy remains unverified. In this study, we aimed to validate the accuracy of HU values measured by implant planning software programs.
