[Dimensional accuracy of thermoplastic impression material Adaptol. Part 1. Influence of handling temperature of impression material].
A thermoplastic impression material Adaptol (J.F. Jelenko & Co.) is used for the impression of denture and has attained good results. But the accuracy of the impression material is not distinct. The purpose of this study was to investigate the influence of handling temperature on dimensional accuracy of the impression material. Part 1. Impressions were made with Adaptol and custom trays. Accura...
متن کاملQuantitative evaluation of palatal bone thickness for the placement of orthodontic miniscrews in adults with different facial types
OBJECTIVES To quantitatively evaluate palatal bone thickness in adults with different facial types using cone beam computed tomography (CBCT). Methods: The CBCT volumetric data of 123 adults (mean age, 26.8 years) collected between August 2014 and August 2016 was retrospectively studied. The subjects were divided into a low-angle group (39 subjects), a normal-angle group (48 subjects) and a h...
متن کاملRisks and complications of orthodontic miniscrews.
The risks associated with miniscrew placement should be clearly understood by both the clinician and the patient. Complications can arise during miniscrew placement and after orthodontic loading that affect stability and patient safety. A thorough understanding of proper placement technique, bone density and landscape, peri-implant soft-tissue, regional anatomic structures, and patient home car...
متن کاملAccuracy of implant impression splinted techniques: effect of splinting material.
Three implant impression techniques, using 3 different splinting materials, were assessed for accuracy in a laboratory model that simulated clinical practice. For group A, an autopolymerizing acrylic resin was used to splint transfer copings. In group B, a dual-cure acrylic resin was used, and for group C, plaster, which was also the impression material, was used. A metal implant master cast wi...
متن کاملMiniscrews for orthodontic anchorage: nanoscale chemical surface analyses.
OBJECTIVES The goal of this study was to determine the chemical composition of the passivation layer of three clinically available orthodontic miniscrews at different depths. MATERIALS AND METHODS The miniscrews used were Aarhus Mini-Implant (AAR), IMTEC Ortho (IMT), and VectorTAS (VEC). The chemical compositions of the as-received miniscrews were determined by X-ray photoelectron spectroscop...
