STATEMENT OF PROBLEM Impressions are made using high-viscosity putty vinyl polysiloxane impression materials in conjunction with disposable plastic stock trays. The impression materials have been shown to be dimensionally stable. However, it remains unclear if the disposable plastic stock trays are rigid enough to resist deformation thus yielding potentially unreliable results. PURPOSE This s...

Case description: An institutionalized 78-year-old man with an extremely damage broken maxillary denture complained about repairing his denture. With the impossibility of repairing, the technique described was proposed so as to offer a treatment that would maximize the comfort of the patient. The maxilla-mandibular relationship was done at the first clinical session, after fabricating the maxil...

OBJECTIVES The aim of this case report was to present the procedure of fabricating a customized occlusal splint, through a revolutionary software that combines cone beam computed tomography (CBCT) with jaw motion tracking (JMT) data and superimposes a digital impression. MATERIALS AND METHODS The case report was conducted on a 46-year-old female patient diagnosed with the temporomandibular di...

OBJECTIVE A maximum mouth opening that is smaller than the size of a complete denture can make prosthetic treatment challenging. This article describes a simple technique used to fabricate maxillary and mandibular custom sectional impression trays for making definitive impressions in patients with microstomia.

INTRODUCTION An accurate and passive fit of implant framework prosthesis, as well as the successful surgical operation is suggested as one of the critical requirements for long-term implant success. OBJECTIVE The purpose of this in vitro study was to evaluate the accuracy of the master cast using open tray impression technique with conventional and novel splinting materials. METHODOLOGY A m...

To provide a mandibular complete denture for patient with partial glossectomy and mandibulectomy, the space was captured using piezography technique involving silicone impression materials two different viscosities. Artificial teeth were arranged within obtained piezographic index, processed in conventional manner. Using described enables physiologically appropriate dentures to be fabricated ba...

Introduction: Angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. The aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. Methods: Seventy edentulous patients at Mashhad Faculty of Dentistry a...
