Abstract:
Specific considerations are needed for the dental treatment of patients with rheumatoid arthritis because they may experience disease-related problems such as trismus, impairment of the temporomandibular joint or hands, and side effects of medication that affect alveolar bone. Here we describe successful prosthetic treatment that addressed disease-related problems, including trismus, in a patient with rheumatoid arthritis. (Int J Maxillofac Prosthetics 2022;5:18-21)

Abstract:
Objective consonant evaluation using palatograph tracing and digital acoustic assessment methods are valuable tools for speech assessment that can be used to track speech improvement in patients wearing a removable prosthesis. In this case report, we employed the psychoacoustic parameter – sharpness - to compare the quality of consonants in a cleft palate patient while wearing the old prosthesis, the new prosthesis, and the new prosthesis following palatogram guided modification. The result suggests that sharpness can be successfully analyzed as a criterion to monitor consonants quality during prosthesis fabrication for cleft palate patients.

Abstract:
Facial prostheses are often fabricated for cosmetic and psychological reasons for patients with facial defects after tumor resection. Each case is unique, and fabricating a facial prosthesis that is tailored to the individual patient requires use of specific materials and a degree of flexibility. This article describes a facial prosthesis that was made using an Adams clasp and acrylic resin for an elderly patient with metal exposure after mandibulectomy.

Abstract:
A lingual augmentation prosthesis (LAP) is an appliance attached to the mandible to increase swallowing by extending the denture base area. It has been proven that the swallowing function improves with the insertion of an LAP assisting the palatal augmentation prosthesis (PAP). We delivered both the PAP and LAP to a patient with subtotal glossectomy who experienced saliva drooling and masticatory dysfunction. As the dead space between the reconstructed tongue and dentures decreased in both the vertical and anterior directions, his maximum tongue pressure increased, and the status of salivation and food residue improved. LAP assisted not only for saliva drooling control but also mastication.

Abstract:
Purpose: Few studies have focused on the feasibility and accuracy of intraoral digital impressions for maxillectomy defects, especially for extensive soft tissue defects. Using intraoral scanners alone might be feasible for producing maxillary obturator prostheses, albeit with some limitations. It seems logical to investigate this ambiguity. Therefore, this systematic review aimed to assessing the feasibility and accuracy of using intraoral scanners (IOSs) to digitize maxillectomy defects. Materials and Methods: PubMed, the Cochrane Oral Health Group Trials Register, and the Cochrane Central Register of Controlled Trials were electronically searched, and five prosthodontics journals were manually searched for English-language articles published as of December 2020 that assessed the feasibility and accuracy of using intraoral scanners to acquire digital impressions for maxillectomy defects. Results: Two in vitro studies, three clinical studies, six clinical reports, and three techniques were included (N=14). Aramany’s and Brown’s classifications were used to classify defects in twelve and one articles, respectively; the remaining article did not specify defect class. The 3M True definition IOS with Cone-beam computed tomography (CBCT), Computed tomography (CT), and/or optical scanners were used in both in vitro studies, mainly to evaluate accuracy. The Trios 3 scanner was used in nine studies as the main resource for data acquisition (75.0%), whereas the Trophy 3DI, Lava, and Cerec Omnicam scanners were used in three articles (25.0%). Four degrees of feasibility were identified: feasible (14.3%), feasible with limitations (28.6%), feasible with CBCT or CT (35.7%), and feasible with conventional impressions (21.4%). Accuracy was evaluated in four studies but was not mentioned in ten studies. Conclusion: The results revealed a low level of evidence for the feasibility and accuracy of using intraoral scanners to digitize maxillectomy defects. Additional multicenter clinical studies are needed to evaluate the feasibility and accuracy of digital workflow compared with the conventional approach.

Abstract:
Purpose: Xerostomia is a symptom of reduced oral functioning and can cause dysphagia and worsen dental disease. This study sought to investigate the actual status of xerostomia in head and neck tumor patients and the beneficial effects of maxillofacial prosthesis use on xerostomia. Materials and Methods: We conducted a questionnaire survey on xerostomia and measured resting salivary flow rate and oral mucosa moisture levels in 26 patients who had been treated for head and neck tumor. Results: After treatment, 16 of the 26 patients (62%) reported experiencing dry mouth. Moreover, 12 patients (46%) reported a tendency for dry mouth compared with before tumor treatment, indicating they perceived worsening of xerostomia after treatment. Mean resting salivary flow rate measured by the cotton roll method was 0.183 ± 0.178 g over 30 seconds. Resting salivary flow rate was significantly lower in patients who reported always having dry mouth than in those who did not report experiencing dry mouth. Patients who had been treated for mandibular/lingual tumors had a significantly lower resting salivary flow rate than those who had been treated for maxillary tumors. Mean moisture content in the oral mucosa measured with an oral moisture checker was 27.6 ± 1.6. Those who reported always having dry mouth had significantly lower oral mucosa moisture content than those who reported having dry mouth sometimes/a little. Five patients reported that wearing a maxillofacial prosthesis alleviated dry mouth. Conclusion: This study demonstrated that the maxillofacial prosthesis use can improve xerostomia after head and neck tumor treatment. (Int J Maxillofac Prosthetics 2021;4:9-17)

Abstract:
Purpose: This study investigated the use of digital technology in maxillofacial prosthetics among practitioners involved in maxillofacial prosthetic rehabilitation in Japan. Materials and Methods: A self-administered survey questionnaire with 24 closed-ended and multiple choice questions was used. A total of 300 questionnaires were distributed at the 32nd meeting of the Japanese Academy of Maxillofacial Prosthetics that was held in Tokyo, Japan in June 2015. The survey questionnaire was distributed in a pack that included an introduction letter explaining the research aims, objectives, and informed consent. The data obtained were analyzed by descriptive statistical methods and reported as frequency and range. Results: In total, 105 respondents (77 men (73.4%), 28 women (26.6%); median age, 40 years; age range 21-66 years) completed the questionnaire (response rate, 35%). The majority of respondents were dentists (75.2%), followed by dental technicians (21.9%). The median duration of work experience for the respondents in their specialty was 14 years, and 97% of respondents had interested and adopted digital technologies in maxillofacial prosthetics. Digital technologies were used significantly in patient and practice management, diagnostic, and patient’s defect visualization (p < 0.001) but insignificant in treatment planning (p = 0.917). In contrast, there were significant increases in non-use of digital technologies in prosthesis design, prosthesis manufacturing, and patient and prosthesis evaluation (p < 0.001). Conclusion: Japanese dental practitioners are interested and willing to use digital technology in maxillofacial prosthetics. Most respondents use some or a substantial number of digital technologies in clinical practice. (Int J Maxillofac Prosthetics 2021;4:25-36)

Abstract:
The reconstruction of cephalic defect and more precisely from the face is not a recent issue. Indeed, the use of facial masks in a symbolic perspective was reported in ancient Egypt. Few references to facial prostheses are then found. It is really only with the work of the French surgeon Ambroise Paré that the first surgical techniques concerning facial epithetics are described. Techniques and materials tend to evolve over the centuries. But then came WWI, which marked a major turning point and brought to light the broken faces and the impact of maxillofacial trauma. Rehabilitation became a major issue in society. The war was a driving force for change from both a surgical and prosthetic point of view, revealing in particular such brilliant designers as the American sculptor Anna Coleman Ladd. Today, the profession is undergoing a major upheaval, linked to the growing development of biotechnological constructions. This historical review aims to retrace the evolution of the rehabilitation of facial substance loss over the ages and to outline the prospects for the foreseeable future.
