“…Oral and maxillofacial surgery was the first branch to implement this technology. A multidisciplinary team is necessary to use 3D printing in the medical industry [ 4 ]. The majority of surgeons are unfamiliar with 3D printing methods, and most low-cost printers necessitate basic engineering skills for troubleshooting and computer-aided design (CAD).…”

Maxillofacial reconstructive implants are typically created in standard shapes and have a widespread application in head and neck surgery. During surgical procedures, the implant must be correctly bent according to the architecture of the particular bones. Bending takes practice, especially for untrained surgeons. Furthermore, repeated bending may increase internal stress, resulting in fatigue in vivo under masticatory loading and an array of consequences, including implant failure. There is a risk of fracture, screw loosening, and bone resorption. Resorption, infection, and displacement are usually associated with the use of premade alloplastic implants and autogenous grafts. Recent technological breakthroughs have led to the use of patient-specific implants (PSIs) developed by computer-designed additive manufacturing in reconstructive surgery. The use of computer-designed three-dimensional (3D)-printed PSI allows for more precise restoration of maxillofacial deformities, avoiding the common difficulties associated with premade implants and increasing patient satisfaction. Additive manufacturing is something that refers to a group of additive manufacturing methods. This technique has been quickly used in a variety of surgical procedures. The exponential expansion of this technology can be attributed to its enormous surgical value. Adding 3D printing to a medical practice can be a rewarding experience with stunning results.

Restoring the maxillary resection defect involving the alveolar process, the hard and soft palate and the paranasal sinuses in terms of phonetics, mastication and deglutition is more challenging, especially with young patients with aesthetic concerns.This case report describes the prosthodontic rehabilitation of a young patient with a unilateral subtotal maxillectomy due to post-COVID-19 mucormycosis. A patient-specific subperiosteal implant was planned to rehabilitate the patient’s bony defect. Using postsurgical CT, a customised subperiosteal titanium framework was fabricated by the direct metal laser sintering method using grade IV titanium alloy. The fabricated framework was implanted over the patient’s zygomatic anatomic contour. Three months later, the patient-specific implant was unveiled to the oral cavity, an open-tray impression was made and the fixed implant prosthesis was fabricated.This case report opens a new realm of rehabilitation for severely compromised maxillary bony defects and impaired oral functioning with no other viable conventional reconstruction options.
