Brief Summary

Chronotherapy is an emerging field in biomedicine that leverages on fine-tuning the timing of drug delivery to obtain a therapeutic effect. Dr. Tamimi and his team have successfully harnessed chronotherapy using NSAIDs to enhance bone healing in a murine fracture model. Unpublished findings revealed that mice receiving carprofen for 3 days post-fracture exclusively during activity hours exhibited superior bone healing outcomes in comparison to specimens that received the same drug during resting hours. This is a 3-arm RCT aimed at evaluating the effect of different chronotherapeutic NSAID regimens on intraoral bone healing in humans using an extraction socket healing model in the context of an early implant placement protocol. The primary aim is to elucidate whether there are differences in osteogenesis and in the characteristics of the newly formed bone between patients following different post-operative NSAID chronotherapeutic protocols. Secondary endpoints of interest include assessment of alveolar bone and soft tissue dimensional changes between pre- and post-extraction, implant insertion torque, serum CRP levels, wound healing index and patient-reported discomfort at different time points. If proven beneficial, the proposed chronotherapeutic approach could be readily implemented in clinical practice as a standalone therapy or as a valuable complement to existing standard-of-care protocols, due to its simplicity, safety and cost-effectiveness.
