Compare the Difference in Occlusal Force Distribution and Denture Retention Using 2 Different Denture Base Materials in Implant Retained Overdenture

The global increase in the aging population has led to a rise in total edentulism, which remains a major public health concern. two-implant-retained mandibular overdentures have been regarded as the standard of care, offering superior retention, stability, comfort, and masticatory efficiency compared to conventional dentures. Among available attachment systems-bar, ball, stud, and magnet-the Equator attachment has gained popularity due to its low vertical profile, suitability for limited inter-occlusal space, and ease of handling. Assessment of masticatory performance and occlusal balance can be objectively measured using devices such as bite force analyzers and the computerized T-Scan system, which quantifies occlusion and disocclusion times. Conventional heat-cured polymethyl methacrylate (PMMA) remains the most widely used denture base material; however, it has mechanical and biological limitations. Flexible denture base materials have been introduced to overcome these drawbacks by enhancing adaptation, distributing occlusal loads more evenly, and improving comfort and retention.

Clinical Effects of Keratinized Mucosa Augmentation Around Dental Implant With Free Gingival Graft in Different Surgical Timing at Mandibular Posterior Sites

This study aims to compare clinical outcomes and tissue stability at implant sites in the mandibular posterior region with insufficient buccal keratinized gingiva. It will assess the use of free gingival grafts either before or during the second stage of implant surgery.

Evaluation of Bone Changes Around Implants in Patients Treated With All on Four

The Goal of the clinical trail is to evaluate the Bone height changes around two axially placed anterior implants and two distally inclined 30-degree angle posterior implants in comparison to two axially placed anterior implants and two distally inclined 45-degree angle posterior implants using cone beam CT (CBCT). Patients will visit the clinic after the surgery and after the framework and denture insertion for check ups and during the follow up periods ( at denture insertion, 6 months and 12 months)
