PLLA Membranes Enriched with Chitosan/DCPA: Innovative Approach to Bone Tissue Engineering.

Bone tissue engineering has been very promising. The use of scaffolds of synthetic and natural materials is an alternative to combine the advantages of both types of materials. This study aimed to evaluate electrospun polymeric matrices of pure PLLA or associated with 5% or 10% of chitosan particles loaded or not with DCPA in bone proliferation and differentiation of periodontal ligament stem cells (PDLSC).

Effect of the attachment system on the biomechanical and clinical performance of overdentures: A systematic review.

Statement Of Problem: Overdentures can improve the quality of life of elderly patients compared with conventional complete dentures. Different attachment systems can be used to retain these prostheses, but which system results in better function, mechanical performance, and patient comfort is unclear.

Purpose: The purpose of this systematic review was to evaluate randomized clinical trials to compare overdentures supported by either bar and clip or ball and O-ring attachments for retention, masticatory efficiency, bone loss, and patient satisfaction.
