Squamous cell carcinoma is a common malignant condition affecting the oral cavity and may involve the surrounding maxillofacial regions. Treatment commonly involves resection of the tumor, followed by prosthetic rehabilitation of the resection defect. This clinical report presents a 62-year-old Asian male patient who had previously undergone surgical resection, resulting in a post-surgical Aramany Class II maxillary defect. The patient\'s medical history included severe trismus, characterized by restricted mouth opening, as well as a diagnosis of maxillary sinus verrucous squamous cell carcinoma. This report provides a comprehensive account of the rapid fabrication of an interim obturator using digitally assisted dentistry techniques.

Mucormycosis is a rare but often fatal fungal infection caused by a group of fungus known as the Mucorales. This fungus can cause varieties of infections in human beings, especially in an immunocompromised condition. According to various studies, the mortality rate ranges from 10% to 100% depending on the location and site of infection accompanied by underlying diseases. Rhinomaxillary involvement is the most common form of mucormycosis predominantly occurring in patients with uncontrolled diabetes. Necrosis of the maxilla in patients with rhinomaxillary form is less evident as the maxilla is richly vascular, but in case of immunocompromised status, it becomes a common clinical finding. Due to the necrosis of the maxilla, maggots have been found in the nasal and oral cavity which adds to the deteriorating clinical condition. This case report describes a combined medical, surgical, psychological, and prosthetic approach in effectively managing one such case of rhinomaxillary mucormycosis.

Prosthetic rehabilitation of extensive maxillectomy defects are exigent given the difficulties faced due to loss of palatal bone,teeth and surrounding supporting tissues which help in retention, support and stability of the prosthesis. An interim maxillary obturator is a prosthesis which is made after surgical resection of a portion or all of one or both maxilla where initial healing is completed. Frequently many or all teeth in the defect area are replaced by this prosthesis. It plays a vital role in preventing the facial disfigurement and irritation to the surgical site thereby enhancing the healing and restores the functional capabilities such as speech, mastication, deglutition etc. To gain better retention and stability, preservation of the unaffected regions is needed which can be achieved by proper surgical planning and designing of the prosthesis. This case series describes rehabilitation of three extensive maxillectomy defects with hollow open and closed interim obturators.

Treacher Collins syndrome has been described as a syndrome involving 1st and 2nd branchial arches, affecting various organs in the craniofacial region. Affected infants report with nasal regurgitation and minimal dietary intake due to cleft palate, consequently show delayed and retarded growth. The situation is further complicated when the repair of the palatal defect is postponed due to delayed milestones. At this juncture, it is of paramount importance to intervene prosthetically and close the defect with the aid of an interim obturator. Herein we describe a simple, yet successful, chairside approach to make an impression of an infant without the aid of any kind of anesthesia.
