Effects of condylar neck inclination and counterclockwise rotation on the stress distribution of the temporomandibular joint.

Three different kinds of condylar inclination were manually modelled anteriorly inclined condylar neck, vertical condylar neck, and posteriorly inclined condylar neck. Three different maxillary impactions were simulated to evaluate the effect of counterclockwise rotation. The von Misses stresses of the disc, compressive stresses of the glenoid fossa, and compressive stresses of the condyle were the highest in the models with posteriorly inclined neck and lowest in the models with vertical condylar neck design.

Analysis of Satisfaction Levels in Completely Edentulous Patients Treated with Different Configurations of Implant- Supported Prostheses.

Purpose: To evaluate and compare patient satisfaction levels in edentulous patients treated with different configurations of implant-supported prostheses as well as previous prosthesis experiences before implant treatment.

Materials And Methods: A study population of 142 patients was identified and separated into four treatment groups: group 1 comprised 43 patients treated with an implant-supported overdenture in the mandible and conventional complete denture in the maxilla; group 2 comprised 32 patients treated with implant-supported overdentures in the maxilla and mandible; group 3 comprised 26 patients treated with an implant-supported overdenture in the mandible and a fixed prosthesis in the maxilla; and group 4 comprised 41 patients treated with implant-supported maxillomandibular fixed restorations. Questionnaires asking about masticatory performance, pronunciation, comfort, and social ability were used to evaluate treatment outcomes.

Is Incisive Papilla a Good Landmark to Predict Clinical Outcomes and the Esthetic Perceptions of Edentulous Patients Treated with Implant-Supported Fixed Prostheses on Maxillae?

To investigate the effect of incisive papilla on esthetic ratings and lip support for patients who are treated with implant-supported fixed prostheses on edentulous maxillae. A study population of 118 patients with maxillomandibular edentulism was identified. A self-administered questionnaire was used to evaluate treatment outcomes through a patient perspective.

Evaluating the changes in nasal airway volume and nasal airflow after surgically assisted rapid maxillary expansion.

Objective: This study aims to compare the changes in the nasal airway volume and nasal airflow using acoustic rhinometry (AR), rhinomanometry (RMN), and dental volumetric tomography (DVT) after surgically assisted rapid maxillary expansion (SARME).

Study Design: Our study consists of 13 adults, 3 male and 10 female patients, aged between 15 and 26, with completed skeletal development. In our study, DVT imaging was obtained twice, preoperation and 3 months after expansion.
