Abstract OBJECTIVES: To measure and compare the size of the cement gap of wax and polymer copings and final glass-ceramic crowns, produced from conventional and digital workflows, one additive and one subtractive. METHODS: Thirty wax copings were made by conventional manual layering technique and modeling wax on stone models with spacer varnish si...
Article
Statement of problem: Limited information is available on the trueness and precision of intraoral scanners (IOSs) for scanning dentate and edentulous casts. Purpose: The purpose of this in vitro study was to evaluate the trueness and precision of 5 different IOS devices for scanning a dentate and an edentulous cast in a standardized way for shor...

Artificial designs and features usually control production workflows in the industry. The operator has the freedom to adapt designs to achieve the desired function; when the operator is satisfied, mass production of the two objects is possible. The production workflow for prosthetic restorations in dentistry is a fairly complicated procedure that r...

Aim: To measure the trueness and precision under repeatable conditions for different intraoral scanners (IOSs) when scanning fully edentulous arch with multiple implants. Materials and methods: Three IOSs and one industrial scanner were used to scan one edentulous master cast containing five implant scan bodies and three spheres. The cast was sc...

Aim: The use of colored translucent zirconia may enable restorations of a more natural tooth-like appearance than previous opaque white zirconia. The shift from non-colored to colored zirconia may however entail a risk of reduced strength. The aim of the present study was to compare fracture load and fracture mode of fixed dental prostheses framewo...
Article
Objective: To evaluate the accuracy and precision of objects produced by additive manufacturing systems (AM) for use in dentistry and to compare with subtractive manufacturing systems (SM). Methods: Ten specimens of two geometrical objects were produced by five different AM machines and one SM machine. Object A mimics an inlay-shaped object, whi...
Article
Purpose To validate the well‐known and often‐used impression replica technique for measuring fit between a preparation and a crown in vitro. Materials and Methods The validation consisted of three steps. First, a measuring instrument was validated to elucidate its accuracy. Second, a specimen consisting of male and female counterparts was created...
Article
Objectives: To determine the production tolerance of four commercially available additive manufacturing systems. Methods: By reverse engineering annex A and B from the ISO_12836;2012, two geometrical figures relevant to dentistry was obtained. Object A specifies the measurement of an inlay-shaped object and B a multi-unit specimen to simulate a...
Article
Purpose: To measure the horizontal machining tolerances of the interface between internal- and external-hexagon implants and analogs with corresponding components after delivery from the manufacturer. These values may be a valuable tool for evaluating increasing misfit caused by fabrication, processing, and wear. Materials and methods: Seven imp...
Article
Titanium or zirconium computer-aided design/computer-aided manufacturing abutments are now widely used for aesthetic implant treatments; however, information regarding microscopic structural differences that may influence the biological and mechanical outcomes of different implant systems is limited. Therefore, the characteristics of different conn...
Conference Paper
Purpose: Passive fit is commonly discussed when a framework is retained on implants. Nonpassive fit frameworks are believed to lead to overload, which could result in loss of osseointegration and framework failure. Even though passive fit is a known term, the exact definition and range of room of play is not. The aim of this study was to verify the...
