Context: Prosthetic rehabilitation of acquired maxillary defects with Maxillary Resection Prostheses (MRPs) remains biomechanically challenging, particularly in partially edentulous patients, where conventional clasp-retained designs often yield suboptimal retention, stability, and functional outcomes. Research Gap: The integration of telescopic crown systems with semi-precision attachments incorporating a rotational latching mechanism has not been previously described as a unified approach t...
