PURPOSE The purpose of this in vitro study was to investigate the effect of impression technique and implant angulation on the impression accuracy of external- and internal-connection implants using a novel experimental device. MATERIALS AND METHODS An experimental device was designed and fabricated to make in vitro impressions by means of open- and(More)
The paper presents computer-aided methods that allocate a dental implant and suggest its size, during the pre-operative planning stage, in conformance with introduced optimization criteria and established clinical requirements. Based on computed tomography data of the jaw and prosthesis anatomy, single tooth cases are planned for the best-suited implant(More)
STATEMENT OF PROBLEM Increased technical failure has been reported for cross-arch fixed partial dentures (FPDs), particularly for cantilever units with minimum osseous support. PURPOSE The purpose of this study was to investigate the effect of severely reduced bone support on the stress field developed within the connectors for 3 types of cross-arch FPDs.(More)
STATEMENT OF PROBLEM Inadequate dimensioning of the connectors in a cantilever cross-arch fixed dental prosthesis (FDP) in perioprosthetic patients jeopardizes the prognosis of the restoration. PURPOSE The purpose of this study was to investigate the effect of increasing the vertical dimension (VD) on the maximum stress developed within the connectors(More)
PURPOSE Insufficient coronal tooth structure may require restoration of endodontically treated (ET) teeth with cast posts and cores (CPCs). The prognosis for these teeth is a matter of scientific debate, especially if they serve as distal abutments in cantilever fixed dental prostheses (FDPs). The purpose of this study was to study stress field development(More)
STATEMENT OF PROBLEM Periodontally compromised teeth (PCT) that serve as terminal abutments (TAs) are often challenging depending on the post-and-core treatment, the type of partial fixed dental prosthesis (PFDP), and the periodontal support. PURPOSE The purpose of this study was to investigate the biomechanical impact of 3 types of PFDP supported by cast(More)
AIM The objective of this study was to assess if avibactam, a new β-lactamase inhibitor, can restore the potency of carbapenems, a sub-class of β-lactams, against Mycobacterium abscessus clinical isolates. MATERIALS & METHODS 28 M. abscessus clinical isolates that are resistant to multiple drugs currently used to treat its infection were included. MIC of(More)
