“…The masticatory performance was evaluated after the insertion of the new obturator by measuring glucose extraction while masticating a piece of gummy jelly (Glucorumn; GC Corp., Tokyo, Japan) [16]. Considering the larger size of the defect in the present case, the patient's masticatory efficiency (106.6 mg/dL) was comparable to the results of a previous study that reported a masticatory efficiency of 99.6 mg/dL (59.0-124.0) for an acrylic resin obturator and 126.0 mg/dL (118.0-142.0) for a soft-liner obturator in patients who underwent partial maxillectomy [17].…”

We aimed to introduce a simple method for refabrication of an implant-retained obturator using the denture duplication technique while retaining the custom abutments for a patient who underwent bilateral maxillectomy and reconstruction with a free fibula osteocutaneous flap. We have proposed this technique to facilitate the impression-making procedure for this extensive maxillary defect and to avoid lengthy and complicated laboratory procedures. Methods: A custom tray was developed by duplicating the fitting surface of an old obturator using silicone putty. The tray was used for a bite-pressure impression wherein both definitive impression and jaw relation were obtained simultaneously, reducing the time required for the placement of a new obturator. Conclusion: We used the denture duplication technique to refabricate an implant-retained obturator while retaining the custom abutments. Decreased chairside time, fewer visits, the use of easily available materials, and uncomplicated laboratory procedures make this technique more economical and acceptable for patients. Using this approach, the patient was able to use the old prosthesis until the delivery of the new prosthesis. The replacement obturator that was developed using this method maintained an acceptable level of oral function.

A BSTRACT Mucormycosis, a rare fungal infection seen in diabetes, is now very frequent owing to the deadly triad of COVID-19 infection, diabetes, and rampant use of corticosteroids. Early diagnosis and treatment can reduce the mortality and morbidity of this lethal fungal infection. Treatment principles may include antifungal agents along with surgical debridement or resection. The surgically removed palate can have a devastating effect on the appearance and speech of the patient. Obturators allow patients to eat and drink without any suspicion of food entering the oroantral cavities/pharynx during mastication. This case series presented the prosthodontic rehabilitation of nine post-COVID rhinocerebral mucormycosis-infected patients with complete or partial defects.

Background: Oral rehabilitation through prosthetic management after cancer resection is a conservative and effective modality in improving patients’ oral health-related quality of life. However, it is challenging to obtain sufficient retention for hemimaxillectomy and edentulous cases without the use of Osseo-integrated implants. Purpose: This case aims to explain the oral rehabilitation management of post-hemimaxillectomy for edentulous patients using a hollow bulb obturator and long-term soft liner. Case: A 63-year-old female presented to the Universiti Malaya postgraduate dental clinic and complained of a loose obturator during speaking and eating and high resonance during speaking. Seven years ago, she underwent hemimaxillectomy surgery of the left hard palate for the removal of squamous cell carcinoma. Upon examination, she had an edentulous maxillary arch, with a large palatal defect; the lateral border of the defect was lined with a skin graft. The mandibular arch was partially dentate with three teeth remaining (33, 35, 43). Case Management: First, elective root canal treatment of the mandibular canines was done to use them as abutments for a mandibular overdenture. Next, a maxillary hollow bulb obturator and a mandibular overdenture were constructed. Then, after evaluating the airspace on the defect site, the lateral and posterior borders of the obturator were modified to be better utilized for retention. Conclusion: Oral rehabilitation of hemimaxillectomy cases with a hollow bulb obturator without the use of Osseo-integrated implants can be a viable option for improving patients’ mastication, and speech, after assessing the retention factors, including the seal, available undercuts, and occlusion.
