While dealing with a grave second wave of ongoing pandemic COVID-19, India also saw a surge in cases of COVID-19-associated mucormycosis, a systematic fungal infection caused by the Mucorales species. Mucormycosis is a highly angioinvasive, rapidly spreading fungal infection. In numerous cases of mucormycosis, bilateral subtotal maxillectomy was performed due to unpredictable and indefinable advancement of fungus clinically. Effective obturation of bilateral maxillectomy defect is a difficult task and as this is a relatively uncommon surgical problem, insufficient data are available on the construction of delayed surgical obturator for such cases. The aim of this article is to discuss the design of Z-spring-retained delayed surgical obturator which is easy to fabricate, easy to rectify, cost-effective, and comfortable for the patients compared to previous spring-retained obturators. This surgical obturator is retained through Z-spring made of 1.02 mm thick wire. Due to the thick gauge, this spring counters postsurgery trismus and develops the seal between the acrylic plate and dorsum of the tongue during deglutition thus helps the patient in taking a soft diet initially. Novelty in this case is the design of the spring, which makes it beneficial for both patient and prosthodontist.

<p class="abstract">The prosthodontic management of impacted tooth that failed to extrude after orthodontic traction is a clinical challenge. There are many factors for orthodontic treatment failure like ankylosis and root exposure. Prosthodontic treatment options include surgical removal of failed tooth followed by implant placement either using staged approach or simultaneous approach. In this case report, the tooth that failed to erupt after orthodontic traction and tooth with root resorption in esthetic zone was managed successfully by immediate implant placement. Guided bone regeneration was performed along with implantation to compensate associated bone loss.</p>
