A technique for the fabrication of an open combination (hard-resilient) obturator prosthesis with VLC materials for patients undergoing partially edentulous maxillectomy is described. VLC denture resins and resilient liners are an exciting innovation in prosthodontic treatment and offer the maxillofacial prosthodontist a wider choice of treatment modalities. The technique and the resultant obturator prosthesis have the following advantages: 1. The ease and rapidity of the technique saves time for both the patient and the maxillofacial prosthodontist by introducing the open obturator prosthesis at the earliest opportunity. 2. The combination open obturator prosthesis provides a stable record base for securing jaw relation records. 3. The thickness and resiliency of the obturator prosthesis can be managed more easily. Flexibility and resiliency can be modified by the thickness of the resilient liner or by adding a rigid scaffolding according to the clinical requirements. 4. Prostheses are easy to repair or modify by using increments of VLC hard or resilient materials. 5. The combination VLC obturator prosthesis provides stability, retention, and decreased weight and obduration of residual palatal defects. 6. The technique can be used for partially edentulous or edentulous patients after maxillary resection.

Introduction: In children, polymethylmethacrylate (PMMA) is a commonly used material for fabrication of dental prostheses, such as obturators, removable space maintainers, habit-breaking appliances, removable orthodontic appliances, and removable partial and complete dentures. Regular cleaning of such prostheses is vital for maintaining the health of the oral tissues as well as the longevity of the prosthesis. The chemical method of disinfection, using different chemical cleansers, is commonly used for cleaning a dental prosthesis.

Purpose: This study aims to evaluate the effectiveness of a case-based reasoning (CBR) system in predicting the design of definitive obturator prostheses for maxillectomy patients.
Materials And Methods: Data from 209 maxillectomy cases, including extraoral images of obturator prostheses and occlusal images of maxillectomy defects, were collected from Institute of Science Tokyo Hospital. These cases were organized into a structured database using Python's pandas library.

Background: To spare important anatomical structures from damage during treatment of cystic odontogenic lesions, decompression has become a conservative alternative to enucleation. Marsupialization, in combination with the use of a custom-made decompression prosthesis, is an effective method of inducing reduction and bony infill of cystic lesions of the jaw.
Methods: In this case series and review of the literature, we describe three patients with odontogenic cysts of the mandible who were treated with custom-made decompression obturator prostheses (DOP) at the Memorial Sloan Kettering Cancer Center Dental Service.

Orbital defects can result from a myriad of underlying diseases and injuries. Treatment of malignant neoplasms and maxillofacial trauma are common reasons for orbital exenteration. Recently, a growing number of cases of orbital defects have been reported due to mucormycosis in patients with COVID-19.
