Validating an alternate version of the chewing function questionnaire in partially dentate patients.

Background: The aim of this study was to investigate the dimensionality, reliability, and validity of an alternate version of the chewing function questionnaire in partially dentate patients in Japan.

Methods: Subjects were partially dentate patients who attended the prosthodontic clinic at Tokyo Medical and Dental University (N = 491, 71% women, mean age (+/- SD): 63.0 +/- 11.

Clinical evaluation of semi-adjustable articulators: reproducibility of sagittal condylar path inclination assessed by a jaw-tracking system with six degrees of freedom.

Purpose: To validate whether the data for individual patients are correctly reproduced in sagittal condylar path inclination of the articulator, the data obtained by the conventional anterior check bite method and the data obtained by a jaw-tracking system with six degrees of freedom were compared.

Methods: In 5 subjects (4 males and 1 female) with healthy tooth alignments, 5 anterior check bites were obtained from each subject. Sagittal condylar path inclination was measured using seven types of semi-adjustable articulator.

Management of bruxism-induced complications in removable partial denture wearers using specially designed dentures: a clinical report.

In patients with a limited number of remaining teeth, bruxism force can be destructive for both the remaining teeth and periodontal structures. This paper reports the successful management of four such patients with severe sleep bruxism, using conventional removable partial dentures and specially designed, splint-like removable partial dentures called a night denture. The night denture was fabricated in two different designs, which depended upon the pattern of the remaining tooth contacts.

Do patients have a preference for major connector designs?

Aim: The aim of this research was to evaluate patients' preferences for resin analogs of four major connector designs formulated to have equal rigidity once fabricated in the same alloy.

Methods And Materials: Nineteen Kennedy Class I or II partially edentulous patients participated at two centers. The four major connector analogs (MCAs) were fabricated for each subject using light-polymerizing acrylic resin.

Patients' preference for acrylic resin major connector analogues formulated for titanium alloy removable partial dentures.

Purpose: Aim of this study was to determine patients' preference to acrylic resin major connector analogues (MCA) that simulated strengthened major connector designs formulated for Ti-6Al-7Nb alloy.

Materials And Methods: Four MCA namely wide design (Wide), design with 2 strengthening ridges (2SR), design with 1 strengthening ridge (1SR), and thick design (Thick) were fabricated using light-polymerizing acrylic resin for 10 patients with Kennedy Class I or II partially edentulous maxillary arches. They were asked to wear each MCA in the mouth for 30 seconds in 6 pairs, and to report their preference for each pair.

[Sensory perceptive and discriminative abilities of patients with occlusal dysesthesia].

Purpose: It is not rare for dentists to come across patients who complain of several uncomfortable feelings of occlusion despite the absence of any observable occlusal anomaly or discrepancy. These kinds of symptoms are well defined by the term "occlusal dysesthesia" (OD). This study evaluated the occlusal perceptive and discriminative abilities in OD patients.

Bending properties of strengthened Ti-6Al-7Nb alloy major connectors compared to Co-Cr alloy major connectors.

Statement Of Problem: Although Ti-6Al-7Nb alloy has several excellent mechanical properties, its poor rigidity has limited its clinical use as a material for the fabrication of a removable partial denture (RPD) major connector.

Purpose: The purpose of this study was to develop and evaluate strengthening designs of Ti-6Al-7Nb RPD major connectors in an effort to increase rigidity.

Material And Methods: Four strengthening designs of Ti-6Al-7Nb alloy major connectors were developed using finite element analysis modeling: wide, thick, thick at the middle, and thick at the anterior and posterior borders.
