The Stress Effects of Mandibular Movements on the Temporomandibular Joint With Sagittal Split Ramus Osteotomy.

Purpose: The aim of this study was to evaluate the stress changes in the temporomandibular joint (TMJ) after sagittal split ramus osteotomy (SSRO) with finite element analysis (FEA).

Material And Methods: 5 and 10 mm mandibular setback and advancement were applied to models by using SSRO and a control model without osteotomy evaluated. The articular disc was modeled as superelastic, and the stresses on the articular fossa, disc, and condyle were evaluated.

Partially resorbed unremoved silk sutures after tooth extraction: A unique Case report.

Suturation may remain in the mouth for a long time due to incomplete information to patients due to inadvertency. Forgotten silk sutures might be sunk and cause irritation into the alveolar mucosa.

Accelerated Calcium Phosphate Mineralization by Peptides with Adjacent Oppositely Charged Residues.

Calcium phosphate mineralizing peptides are of special importance for dental and orthopedic applications, such as caries remineralization and improved osteointegration. Uncovering the mechanism of action for such peptides is an ongoing challenge with the aim of a better fundamental understanding of biomineralization processes and developing optimized peptides for clinical use. It has recently been reported that "adjacent oppositely charged residue" motifs are found abundantly in cation binding, inorganic surface binding, or biomineralization-related proteins and may play a key role in the biomineralization events.

Does Incidence of Temporomandibular Disc Displacement With and Without Reduction Show Similarity According to MRI Results?

Purpose: The aim of this study is to assess MRI reports of the patients and to provide retrospective analysis by conducting detailed evaluation of temporomandibular disc position.

Patients And Methods: MRI images of 259 patients from 2008 to 2017 were reviewed retrospectively. Existence of disc displacement in joint with and without reduction, existence of effusion in joint gap, arthritis, degenerative changes in joints and limitation of movement of joint and anatomic characteristics were evaluated.

Comparative Three-Dimensional Finite Element Analysis on Miniplate and Lag Screw Fixation to Symphysis Fractures.

The purpose of this study was to compare the amount of stress on the fracture site via three-dimensional finite element analysis between lag screw and miniplate systems. Solid mathematical models were created from the CT of a patient and a fracture observed in the symphysis area. On the fracture site mini plates and lag screws applied to the bone to fixate segments.

Salivary opiorphin in dental pain: A potential biomarker for dental disease.

Objectives: Opiorphin is a recently discovered peptide shown to inhibit the enkephalin-degrading enzymes and prolong the effects of enkephalins. Although opiorphin is found in high concentrations in saliva, the relationship between salivary opiorphin and orofacial pains is not yet fully understood. We aimed to determine salivary opiorphin concentrations in dental pain related to symptomatic irreversible pulpitis (SIP), and symptomatic apical periodontitis (SAP).
