Influence of Cement Type on its Quality of Removal from Zirconium Oxide Implant-Supported Restorations.

Purpose: To assess excess cement removal after cementation of implant-supported cementretained restorations using different cements.

Materials And Methods: A dental model with soft tissue imitation, 20 individual zirconium oxide abutments, and 20 zirconium oxide crowns were fabricated. Half of the restorations were cemented using resin cement (RX) and the other half with resin-modified glass-ionomer cement (GC).

Interrelationships between distinct circadian manifestations of possible bruxism, perceived stress, chronotype and social jetlag in a population of undergraduate students.

This study investigates the recently hypothesized association between distinct circadian manifestations of possible bruxism in subjects with different chronotype profiles, social jetlag and levels of perceived stress. A cross-sectional study was performed by surveying dental students' of Lithuanian University of Health Sciences. A survey instrument was designed and pilot tested for reliability and validity prior to full-scale administration.

Lithuanian dentists' knowledge, attitudes, and clinical practices regarding obstructive sleep apnea: A nationwide cross-sectional study.

To investigate the knowledge, attitudes toward, and aspects of clinical practice regarding obstructive sleep apnea (OSA) among Lithuanian dentists. A cross-sectional study was carried out during the period from December 2016 to March 2017. A survey instrument was designed and pilot tested prior to full-scale administration.

The relationship between pathological wear of teeth and temporomandibular joint dysfunction.

Objective: Temporomandibular joint dysfunction (TMJD) is quite frequent pathology in population. In scientific literature pathological tooth wear (PTW) is listed among the predisposing factors of it.

Material And Methods: During the survey 189 primary patients of dental department in polyclinic of Panevezys city were examined.

Evaluation of the relationship between the occlusion parameters and symptoms of the temporomandibular joint disorder.

Background: The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD.

Objective: The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system.

The relationship between unilateral mandibular angle fracture and temporomandibular joint function.

PURPOSE. Aim of this study was to analyze relation of occlusal correction and alterations of temporomandibular joint function during treatment of unilateral mandibular fractures. MATERIALS AND METHODS.

Dynamical changes of occlusion and articulation during treatment of mandibular angle fractures.

Outcomes of mandibular fractures were stated as frequent reason of temporomandibular joint dysfunctions. The objective of this study was to evaluate dynamical changes of occlusion and articulation during treatment of mandibular angle fractures. 12 subjects with mandibular angle fractures underwent analysis of occlusion and articulation in all stages of healing.

Finite element analysis of stresses in the maxillary and mandibular dental arches and TMJ articular discs during clenching into maximum intercuspation, anterior and unilateral posterior occlusion.

The objective of this study was to investigate distribution of stresses in the human TMJ discs, generated during clenching into various occlusal positions. The work presents a biomechanical finite element model of interaction of mandibular and maxillary dental arches and the TMJ discs of a particular person, based on real geometrical data obtained from spiral computed tomography two-dimensional images. 3D contour coordinates - point clouds were collected from these images and solid model was created.

A three-dimensional model of the human masticatory system, including the mandible, the dentition and the temporomandibular joints.

The objective of this study was to create a three-dimensional mathematical model of a human masticatory system, including the mandible, the dentition and the temporomandibular joints. Object of research was one 20 year old dead man. The research was approved by Committee of bioethics (Kaunas University of Medicine).
