Association between type of health insurance and dental visits among Ecuadorian older population: evidence from a cross-sectional study.

Background: Dental services are often overlooked within healthcare systems, despite their critical role in overall health. Socioeconomic barriers and disparities in insurance coverage frequently limit access to oral care, particularly among vulnerable populations like older adults.

Objective: To examine the impact of different health insurance types on the frequency of dental consultations among Ecuadorian senior citizens, aiming to highlight gaps in access to care.

Stability of the prosthetic screws of three types of craniofacial prostheses retention systems.

Objectives: This study aimed to evaluate the stability of prosthetic screws from three types of craniofacial prostheses retention systems (bar-clip, ball/O-ring, and magnet) when submitted to mechanical cycling.

Materials And Methods: Twelve models of acrylic resin were used with implants placed 20 mm from each other and separated into three groups: (1) bar-clip (Sistema INP, São Paulo, Brazil), (2) ball/O-ring (Sistema INP), and (3) magnet (Metalmag, São Paulo, Brazil), with four samples in each group. Each sample underwent a mechanical cycling removal and insertion test (=0.

New bone formation in a bone defect associated to dental implant using absorbable or non-absorbable membrane in a dog model.

The aim of this research was to determine the bone formation capacity in fenestration defects associated with dental implants using absorbable and non-absorbable membranes. Six dogs were used in the study. In both tibias of each animal 3 implants were installed, and around these 5 mm circular defects were created.
