Association of masseter muscles thickness and facial morphology with facial expressions in children.

Objective: To evaluate the potential influence of muscular capacity and facial morphology on facial expressions in children.

Materials And Methods: A cross-sectional study was carried out on 40 healthy children (ages 9-13), without previous orthodontic treatment. Masseter muscle thickness and anthropometric facial proportions were measured using ultrasound and digital calipers respectively.

Microbiological evaluation of LOCATOR® Legacy attachments: A cross-sectional clinical study.

Objective: This retrospective cross-sectional study aimed to evaluate quantitatively the oral microbiome in the tri-lobe central cavity of Locator Legacy attachment and verify whether it harbors a different, potentially more pathogenic, bacterial spectrum than the adjacent edentulous ridge.

Materials And Methods: Edentulous patients rehabilitated with implant overdentures using Locator Legacy attachments were recruited for this study. The clinical examination comprised probing depths, mobility, peri-implant, and periodontal health along with intraoral swabs for microbiological evaluation, polymerase chain reaction (PCR) testing, and candida culture.

Clinical performance of LOCATOR® attachments: A retrospective study with 1-8 years of follow-up.

The use of LOCATOR® attachments in implant-supported removable dental prostheses (ISRDPs) has been evidenced with conflicting clinical behavior in literature. This retrospective study aimed to investigate the long-term clinical performance of LOCATOR® attachments by evaluating the frequency of the encountered mechanical complication events (MCEs) and the factors that play a role in attachment wear (AW). The study recruited participants with ISRDPs on LOCATOR® attachments.
