Background & Aim: Rehabilitation of the atrophic mandible has always been a surgical and prosthetic challenge to clinicians. The literature documents diverse reports on the number of implants and the type of prosthetic attachments used to rehabilitate an edentulous mandible. The aim of this presentation is to present a series of 3 thought provoking research projects which when viewed collectively analyse the surgical risk factors in the anterior mandible, the number of implants best suited for overdenture function and the prosthetic attachments that would minimize complications and improve patient reported outcome measures (PROMS). Material & Methods: Study 1: Dentate and edentulous patients were recruited for the analysis of the blood flow in the anterior mandible. CBCT scans and Doppler ultrasonography were performed to determine the correlation between the diameter of the foramen and the blood flow. Study 2: A randomized cross-over clinical trial was performed on edentulous patients. PROMS were recorded in patients after they received overdenture on ADLC and Locator abutments. The sequence of treatment was randomized such that each patient experienced both treatment options for 6 months each. Study 3: A randomized cross-over clinical trial was performed on edentulous patients. PROMS were recorded in patients after they received 3 and 2 implant supported overdentures. The sequence of treatment was randomized such that each patient experienced both treatment options for 6 months each. Conclusions: Study 1 proved that the diameter of the lingual foramen on the CBCT is directly proportional to the blood flow. Therefore a CBCT can be predictably used to assess the vascularity of the mandible. In patients with 2 implant supported overdentures, the ADLC attachments resulted in better retention and a higher patient satisfaction as compared to Locator attachments. Overdentures retained by three implants resulted in higher patient satisfaction compared to overdentures retained by two implants.

Dr Tabrez Lakha completed Masters in Prosthodontics and Implantology from MA Rangoonwala Dental College,Pune, India. He followed this up with a 1 year ITI Scholarship at University of Zürich under the mentorship of Professor Christoph Hämmerle. He is currently an ITI Fellow and an Assistant Professor in Prosthodontics. He has lectured extensively in India and has made presentations at top notch implantology Congresses such as the ITI World Symposium (2021), EAO (Vienna 2018), Osteology Foundation (2019) . His research has also win him awards at the IADR Congress (India, 2015) He has published extensively on implantology is high impact factor journals such as Clinical Oral Implant Research, International Journal of Prosthodontics, Implant Dentistry, Journal of Maxillofacial Surgery, Journal of Prosthetic Dentistry and is a reviewer for important journal such as International Journal of Prosthodontics, International Journal of Esthetic Dentistry, Journal of oral biology and craniofacial research. Dr Tabrez Lakha is also a successful clinician and has a keen interest in developing and implementing restorative protocols using digital workflows. Dr Lakha is passionate about teaching and loves to share his clinical and research acumen with budding and early stage implantologists and Prosthodontists.
