Today, oral disorders are the most prominent and common issues in the world. Investigations reveal oral disorders comprising of gum disease, tooth decay, mouth sores, tooth erosion, tooth sensitivity, toothaches, and dental emergencies. Further, in-depth study identifies improper bonding between denture base and denture teeth ending up with costly repair along with mouth sores. This effect is observed from middle age (35 years) to old age (< 80 years) people in the world. Approximately one-third of the population is suffering because of untreated caries of natural teeth (31.2 %). The optimal composition of PMMA as denture base and denture teeth in clinical trials with observation and experimental methodology is yet to be unleashed. An alternative material for denture base or denture teeth is still an unanswered question. Selection of appropriate reinforcement material encompassing the guidelines for liquid/powder ratio, avoids processes terrible for bond strength, the wax free model. The current work focuses on investigation of mechan-ical properties with/without the reinforcement of a new biomaterial known as limpet teeth (LT). LT is abundantly available in the seashore or intertidal regions. Application of LT in dentistry or as a denture base material is unperceived. A comparative analysis of coupons with/without the reinforcement (in the form of a short/continuous fiber) of LT in PMMA is carried out. The simulation work correlates with experimental work exploring the possibilities of a new material in the field of dentistry. The observed results for mechanical properties such as flexural strength (106 %), microhardness (116 %) and impact strength (125 %) are better in comparison to base PMMA material.
