Distraction of the temporomandibular joint condyle in patients with unilateral non-reducing disc displacement: Fact or fiction?

Objectives: This study investigated the distractive effect of a unilateral pivot splint on patients with unilateral disc displacement without reduction.

Methods: The study group was comprised of 18 patients who had no history of treatment with removable prosthetic restorations of molars, premolars, or canine teeth, and no previous treatment for temporomandibular disorder. Joint spaces measurements made on magnetic resonance images indicated the affected side to be narrower than the healthy side.

The correlation between direction and amount of retrusive movement and condyle position and joint space.

Objective: The direction and amount of retrusive movement may be correlated with the amount of joint space and the maximum intercuspal position of the condyle. The aim of this study was to identify any such correlation using an ultrasonic jaw motion analyzer and digital volumetric tomographic (DVT) scans.

Methods: Thirty-five dental students were selected as subjects.

In vitro comparison of two different materials for the repair of urethan dimethacrylate denture bases.

Purpose: The purpose of this in vitro study was to investigate the flexural properties of a recently introduced urethane dimethacrylate denture base material (Eclipse) after being repaired with two different materials.

Materials And Methods: Two repair groups and a control group consisting of 10 specimens each were generated. The ES group was repaired with auto-polymerizing polymer.

Evaluation of the closest speaking space in different dental and skeletal occlusions.

Statement Of Problem: The closest speaking space (CSS) together with the vertical overlap of anterior teeth during the production of the /s/ sound have not been previously investigated with respect to differences in dental and skeletal orthodontic classifications.

Purpose: The purpose of this study was to investigate the CSS in dental and skeletal occlusions and to analyze the cause and effect relationship of the CSS and the amount of the vertical overlap of anterior teeth.

Material And Methods: Poly vinylsiloxane interocclusal registration material was placed bilaterally onto the occlusal surfaces of premolar and molar teeth of 155 native Turkish speaking adolescent and young adult dentate participants, who were then asked to pronounce the word seyis.

Does the presence of anterior mandibular teeth increase the incidence of denture stomatitis?

Purpose: To compare the frequency of denture stomatitis (DS) under maxillary complete dentures (CDs) in patients with opposing mandibular distal extension removable partial dentures (RPDs) and CDs.

Materials And Methods: Participants included 365 maxillary CD wearers (241 women, mean age 70.5 ± 13.

A simple technique for increasing the occlusal vertical dimension of removable denture wearers.

This article describes a simple and efficient technique for increasing the occlusal vertical dimension of removable denture wearers. Functionally generated path technique is carried out by using gothic arch tracing, and the existing mandibular overdenture is modified for interim use.

Flexural properties of a light-cure and a self-cure denture base materials compared to conventional alternatives.

Purpose: A new light curing urethane dimethacrylate and a cold curing resin with simpler and faster laboratory procedures may have even improved flexural properties. This study investigated the 3-point flexural strengths and flexural moduli of two alternate base materials.

Materials And Methods: A cold curing resin (Weropress) and a light curing urethane dimethacrylate base material (Eclipse).

The effect of mandibular anterior teeth on the hypermobile tissue in the anterior part of the maxilla.

The absence of posterior occlusal contacts may result in increased anterior occlusal contacts and forces between natural mandibular dentition and artificial maxillary dentition. The impact of natural mandibular anterior teeth on the development of hypermobile tissues in the anterior part of the edentulous maxillary alveolar ridge was investigated in this study. The study group consisted of 410 patients with maxillary complete dentures and various mandibular dentitions from seven rest homes in Istanbul.

A quality-of-life comparison between self-aligning and ball attachment systems for 2-implant-retained mandibular overdentures.

The aim of this study was to evaluate the self-aligning overdenture attachment system by comparing its oral health-related quality of life (OHRQL) with a traditionally used ball attachment system. In this randomized, within-subject crossover trial, 25 edentulous subjects each received 2 mandibular implants, and were then assigned to receive either self-aligning or traditional ball attachments. After 3 months, all subjects were switched to the second attachment type.
