Evaluation of Strut retained versus Screw retained patient specific implants in rehabilitation of post COVID mucormycosis maxillectomy Defects. A randomized controlled trial

This randomized controlled trial compares the effectiveness of two types of patient-specific implants in rehabilitating maxillectomy defects resulting from post-COVID mucormycosis. The study evaluates the outcomes of using both strut-retained and screw-retained implants in this context. By assessing factors such as quality of life, ease of surgery , ease of prosthesis fabrication, aesthetic outcomes, and patient satisfaction, the research aims to provide insights into the optimal approach for restoring maxillectomy defects in individuals affected by post-COVID mucormycosis.

Tailored patient-specific implants (PSIs) represent a precise solution for facial reconstruction, with two main types available: PSI with struts (PSI 1) and PSI with screw-retained implants embedded within (PSI 2). Computer surgical planning is crucial for this process, enabling surgeons to strategize and adjust defects and flaps with unobstructed 3D visualization. Integration of 3D-printed cutting guides, based on computer-generated plans, simplifies complex closing osteotomies, effectively translating virtual designs into real-world surgery. Compared to traditional implants, PSIs offer heightened accuracy, superior site adaptation, and reduced operating time. This transformative technology signifies a significant advancement in maxillofacial surgery, providing a more precise, efficient, and patient-tailored approach to reconstruction.

This study is planned in department of oral and maxillofacial surgery Government dental college and hospital Nagpur To evaluate and compare the effectiveness of Strut-Retained and Screw-Retained Patient-Specific Implants in rehabilitation of post covid mucormycosis maxillectomy defect.

Primary research question What is the comparative effectiveness of Strut-Retained and Screw-Retained Patient-Specific Implants in the rehabilitation of Post-COVID Mucormycosis maxillectomy defects ?

Null hypothesis : There is no difference in strut retained and screw retained patient specific implants in rehabilitating post covid mucormycosis maxillectomy defect

Alternative hypothesis : There is difference in strut retained and screw retained patient specific implants in rehabilitating post covid mucormycosis maxillectomy defect.
