Horizontal Ridge Expansion: A Comparative Study of Motorized Ridge Expanders Versus Osseodensification Techniques.

Background: Adequate horizontal and vertical bone volume is an ideal prerequisite to achieving good primary stability, osseointegration, and long-term survival of an implant. Several techniques are available to achieve adequate bone volume for implant placement. Among the various non-subtractive methods, ridge expansion with motorized bone expanders is a commonly used method to expand bone volume in the anterior maxilla.

Evaluation of Impact Strength and Flexural Strength of Polyether Ether Ketone vs. Computer-Aided Design/Computer-Aided Manufacturing Polymethyl Methacrylate Denture Base Materials: An In-Vitro Study.

Objective: The objective is to comparatively assess the impact strength and flexural strength of polyether ether ketone (PEEK) vs. computer-aided design/computer-aided manufacturing (CAD/CAM) polymethyl methacrylate denture base material.

Methods: A total of 90 samples were fabricated with traditional heat cure PMMA, PEEK, and CAD/CAM PMMA and divided into three groups of 30 samples each.
