Fixed Yet Flexible: Non-Rigid Connector Strategy for Pier Abutments – A Case Report

2025-06-06T07:41:30-04:00

Introduction: Pier abutments, located between two edentulous spaces, pose unique biomechanical challenges in fixed prosthodontics. Conventional fixed partial dentures (FPDs) with rigid connectors are often unsuccessful in such cases due to the fulcrum effect, which can lead to prosthesis failure. Non-rigid connectors are a proven solution that allows limited movement within the prosthesis, reducing stress on abutment teeth.

Case Presentation: This case report presents a 29-year-old male patient with missing right maxillary canine and second premolar. The first premolar served as a pier abutment between the edentulous spaces. Clinical and radiographic evaluations confirmed the abutments were periodontally sound. A new prosthetic plan was executed using a porcelain-fused-to-metal FPD incorporating a non-rigid key-keyway connector. The key (male) was placed on the distal surface of the pier abutment, and the keyway (female) on the mesial surface of the pontic replacing the second premolar.

Conclusion: Non-rigid connectors are essential in managing pier abutment cases to reduce stress and enhance prosthetic longevity. This case reinforces the value of biomechanically sound prosthodontic design in achieving long-term success.

Assessment of Knowledge Attitude and Perception of Information and Communication Technology and Computed Assisted Learning Undergraduate Dental Students

Background: The integration of Information and Communication Technology (ICT) and Computer-Assisted Learning (CAL) has transformed modern dental education, offering innovative methods for teaching, learning, and clinical training. Understanding students' knowledge, attitudes, and perceptions toward these tools is vital for effective implementation.

Objective: This study aims to assess the knowledge, attitude, and perception of undergraduate dental students regarding ICT and CAL in their academic and clinical training.

Methods: A cross-sectional survey was conducted among undergraduate dental students using a structured questionnaire. The instrument measured three key domains: knowledge of ICT and CAL tools, attitude towards their use in dental education, and perception of their effectiveness and usability.

Results: The majority of students demonstrated moderate to high knowledge of ICT applications, with a positive attitude toward the use of CAL in enhancing learning outcomes. Most participants perceived ICT and CAL as essential tools for modern dental education but highlighted the need for formal training and better infrastructure.

Conclusion: Undergraduate dental students show favorable knowledge and attitudes toward ICT and CAL. However, gaps in training and access must be addressed to fully leverage these technologies in dental education. Integrating ICT and CAL into the curriculum, supported by institutional resources, can enhance learning efficiency and prepare students for digitalized dental practice.
