Background Evidence concerning the performance of entirely 3D printed digital obturators is insufficient. This prospective randomized, single-blind crossover study aimed to evaluate patient satisfaction with conventional obturators and 3D printed obturators. Methods Ten patients aged between 45 and 65 years with unilateral hemi-maxillectomy due to oncological surgeries were enrolled in a crossover design. Initial treatment involved a conventional obturator with a heat-cured acrylic base and a cast metal framework GI. Following a two-week washout, patients received a fully digitally designed and fabricated obturator incorporating 3D printed materials GII. Satisfaction was assessed using the validated Obturator Functioning Scale (OFS), and statistical analysis was conducted using the Mann-Whitney U test. Results The median of OFS scores of the two groups were statistically significant differences between the two studied groups in terms of functional and aesthetic limitations, with p -values 0.010* and 0.014* respectively. On the other hand, there were no significant differences in chewing limitation and social disability, with p -values of 0.572 and 0.087 respectively. Conclusion Within the limitations of this study, a full digital workflow for producing maxillary obturator prostheses can increase patient satisfaction with respect to functional, aesthetic, and phonetic outcomes. Trial registration This research was registered on www.clinicaltrials.gov in 17-06-2023 with registration number NCT0592081.

Background Maxillary defects predispose patients to different undesirable effects. The aim of this study was to assess the quality of life (QoL) of patients with maxillary defects (acquired/congenital) wearing obturators. Methods The study comprised 30 patients aged between 16 and 78 years. Interviews were conducted to collect information pertaining to patients; sociodemographic, self-reported function of obturator using Obturator Functioning Scale (OFS), self-evaluation of general health using Visual Analogue Scale (VAS), radiotherapy treatment, salivary gland removal, reconstructive surgery, neck dissection and length of time obturators were worn. Clinical examination included type of maxillectomy, Aramany classification of the defect, and evaluation of obturator function using the Kapur retention and stability scoring system. Result Quality of life was affected significantly by marital status ( P  = 0.026). Married patients had better quality of life 61.3%, followed by divorced patients 38.8%, widowed 37.3% and the least QoL was detected in single patients 36.5%. Significant association between the type of maxillectomy and QoL was detected ( P  = 0.002). Retention of obturator prosthesis had a highly significant association with QoL ( P  < 0.001). Type of maxillectomy had a significant relation with obturator retention ( P  = 0.005). Stability had a significant correlation with QoL ( P  = 0.022). Obturator wearers who were treated with radiotherapy had lower QoL than those who were not treated with radiotherapy. Conclusion Rehabilitation of patients with maxillary defects using obturator prosthesis is an appropriate and not invasive treatment modality. Results support that good obturators contribute to a better life quality.

Cancers of the orofacial region can be devastating in their impact on physical structure and function of the affected individual, leading to potentially severe compromises in quality of life. A total of Twenty (20) mandibular resected patients were selected for this study. All the patients’ were rehabilitated with mandibular resection prosthesis. Novel scale known as Maxillofacial Prosthesis Performance Scale (MFPPS) was developed for mandibulectomy patients to assess the oral health related quality of life. This scale has been tested for validity and reliability. The OHRQol was measured using the oral health impact profile (OHIP-Edent-19), Obturator functioning scale (OFS-15) and Maxillofacial Prosthesis Performance Scale (MFPPS-10) with standardized questionnaire after 2 weeks & 3months of prosthesis function for twenty (20) mandibular resected patients. For OHIP –Edent scale; when comparing 2 weeks, all subscale scores shown significant progress on oral health impact profile-Edent scale after 3 months of prosthesis function. For OFS scale; when observing the score of 2 weeks and 3 months, there was dramatic improvement of (75%) in miscellaneous factors which include Problems in dryness of mouth, engagement in social events and obturator positioning. For MFPPS; all rehabilitated patients’ were observed two weeks later, negative impacts have been eliminated and positive impacts increased on oral health. The patient was reviewed again 3months later and confirming an even higher level of overall satisfaction with the Mandibular Resection Prosthesis. The maxillofacial prosthesis had a strong positive impact on quality of life .Hence mandibular resection prosthesis enhance the oral health related quality of life.
