AIM In this study, we investigated the effect of differences in periodontal status in the masticatory performance of dentate subjects with the same occlusal supporting area. MATERIALS AND METHODS The subjects of the analysis were classified into those of Eichner A1-3 (n = 1094) and Eichner B1-4 (n = 529). Subjects' periodontal status was evaluated on the basis of the Community Periodontal Ind...

Objective:  To evaluate the improvement in masticatory performances two weeks after posterior implant restoration.  Material and Methods: Nine patients with missing first second molars were included study. Masticatory evaluated using subjective objective methods utilizing color-changeable chewing gum visual analog scale (VAS) assessment. The subjects asked to chew gums before restoration. Their...

BACKGROUND The purpose of this study was to investigate the influence of occlusal forces (the contractile force of masticatory muscles) exerted during occlusal adjustment on the distribution of the forces among teeth, implants, and temporomandibular joints (TMJs) in intercuspal clenching in cases with bilateral missing molars and premolars by using finite element analysis. METHODS A three-dim...

Introduction Mandibular angle fractures can be treated by various methods, but even the most popular methods may not be able to give satisfactory results, as the pterygomasseteric sling and masticatory forces can result in displaced angle fracture. These displaced fragments cannot be satisfactorily retained by single miniplate fixation. The aim of this study is to assess treatment of displaced ...

Current strategies for jaw reconstruction require multiple procedures, to repair the bone defect, to offer sufficient support, and to place the tooth implant. The entire procedure can be painful and time-consuming, and the desired functional repair can be achieved only when both steps are successful. The ability to engineer combined tooth and bone constructs, which would grow in a coordinated f...

Buccal exostoses are broad-based, non-malignant surface growth occurring on the outer or facial surface of the maxilla and/or mandible, found usually in the premolar and molar region. Etiology is still not established, but it has been suggested that the bony overgrowth can be because of abnormally increased masticatory forces to the teeth. They tend to appear in early adolescence and may very s...

Sleep bruxism (SB) is a parafunctional oromotor habit that can sometimes pose a threat to the integrity of the structures of the masticatory system if the magnitude and direction of the forces exerted exceed the system 's adaptive capacity. Over the years science has tried to provide a consistent explanation of the etiopathogenesis and physiopathology of SB, although the pathophysiological mech...

Objectives: Ceramics have advantages such as optimal esthetics and biocompatibility. However, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of pH, which increase their risk of fracture. Since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair ...

econstruction of the mandible presents unique challenges to the head and neck surgeon. Although mandibular defects can result from trauma, infection, congenital deformities, or osteonecrosis, it most commonly occurs following ablative surgery for the treatment of benign or malignant neoplasms. Primary intrabony mandibular carcinoma is rare; therefore, the involvement of the lower jaw is usually...

The aim of the authors is in conditions of clinical study to investigate the masticatory function in patients with different types of prostheses. Normal function requires the coordinated action of many elements, including teeth, salivary glands, tongue, and masticatory muscles. Dysfunction in any of these areas can result in impaired mastication. Missing teeth and old prostheses are concern to ...
