This clinical report describes the design and fabrication of an implant-retained and soft-tissue-supported obturator prosthesis and a magnetic retained midfacial prosthesis for a patient with a midfacial defect following bilateral total maxillectomy, removal of the left zygoma, and excision of the entire upper lip. The patient underwent multiple head and neck surgeries for 4 separate primary oral cancers, 1 recurrence, and 1 pulmonary metastasis. The definitive obturator prosthesis was retained by 1 zygomatic implant with soft-tissue support and retention. The midfacial prosthesis was attached to the obturator prosthesis with magnets, improving appearance and the recovery of significant aspects of the patient's speech and swallowing. Some improvement in mastication was observed., (Copyright © 2022 Editorial Council for The Journal of Prosthetic Dentistry. Published by Elsevier Inc. All rights reserved.)

The interdisciplinary treatment provided for a 12-year-old boy with fusion of his left central and lateral incisors and concomitant distal space loss is described. His treatment was initiated with orthodontic therapy followed by endodontic treatment of the fused tooth. A conservative zirconia and porcelain cantilevered bonded fixed dental prosthesis was then completed to replace his left lateral incisor., (Copyright © 2023 Editorial Council for The Journal of Prosthetic Dentistry.

Introduction: Surgical site infections (SSI) are a common postoperative complication. During the development of the new WHO guidelines on SSI prevention, also in the Netherlands was concluded that perioperative care could be optimised beyond the current standard practice. We selected a limited set of readily available, cheap and evidence-based interventions from these new guidelines that are not part of standard practice in the Netherlands and formulated an Enhanced PeriOperative Care and Health bundle (EPOCH). Here, we describe the protocol for an open-label, randomised controlled, parallel-group, superiority trial to test the effect of the EPOCH bundle added to (national) standard care in comparison to standard care alone on the incidence of SSI., Methods and Analysis: EPOCH consists of intraoperative high fractional inspired oxygen (0.80); goal-directed fluid therapy; active preoperative, intraoperative and postoperative warming; perioperative glucose control and treatment of severe hyperglycaemia (>10 mmol l-1 ) and standardised surgical site handling. Patients scheduled for elective abdominal surgery with an incision larger than 5 cm are eligible for inclusion. Participants are randomised daily, 1:1 according to variable block sizes, and stratified per participating centre to either EPOCH added to standard care or standard care only. The primary endpoint will be SSI incidence according to the Centers for Disease Control and Prevention (CDC) definition within 30 days as part of routine clinical follow-up. Four additional questionnaires will be sent out over the course of 90 days to capture disability and costs. Other secondary endpoints include anastomotic leakage, incidence of incisional hernia, serious adverse events, hospital readmissions, length of stay and cost effectiveness. Analysis of the primary endpoint will be on an intention-to-treat basis., Ethics and Dissemination: Ethics approval is granted by the Amsterdam UMC Medical Ethics Committee (reference 2015_121). Results will be disseminated through peer-reviewed journals and summaries shared with stakeholders. This protocol is published before analysis of the results., Trial Registration Number: Registered in the Dutch Trial Register: NL5572., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Laryngeal and esophageal laxity resulting from a connective tissue disease can lead to severe pain and functional impairment. This clinical report describes a patient with such significant neck pain that it prevented her from speaking; it also caused pain with deglutition. Maxillofacial prosthetic rehabilitation with an external laryngeal and esophageal support significantly reduced the patient's pain and restored normal speaking and deglutition functions. This clinical report describes the design and fabrication of a support to stabilize the patient's laryngeal and esophageal structures to her midline., (Copyright © 2015 Editorial Council for the Journal of Prosthetic Dentistry.

Orbital tumor, trauma, and necrosis require the orbital contents to be resected and the patient is left with a cosmetic deformity that affects a patient's self-image and those around him or her. Careful planning between the oral and maxillofacial surgeon and/or oculoplastic surgeon and the maxillofacial prosthodontist will result in a secure and accurate esthetic reconstruction using an implant-supported prosthesis. The multiple steps involved in this process require the commitment of doctors and patient. This article reviews surgical and prosthetic considerations in providing a satisfactory esthetic reconstruction of a variety of orbital defects., (Published by Elsevier Inc.)

Prior to the invention of the metal ceramic crown, the pinledge retainer served prosthodontic dentistry for many years. The metal ceramic retainer has been the standard of choice for the majority of fixed partial dentures (FPDs) for nearly 40 years. Recent advances with acid-etched, resin-bonded metal retainers and most recently all-ceramic retainers may have led many to believe that the pinledge retainer is an outdated treatment modality. This clinical report provides examples of several types of pinledge retainers used to restore missing teeth or to splint teeth. These patient examples will also demonstrate that the pinledge retainer can provide excellent esthetics for today's appearance-conscious patients.

A 19-year-old man was admitted with fever, haematuria, general malaise, pain on the left side of the pelvis and a full feeling in the left lower abdominal quadrant of the abdomen. His history mentioned a varices operation. During admission he developed an acute abdomen and deep vein thrombosis in both legs. CT of the abdomen showed a pathologic mass and absence of the vena cava inferior. Laparotomy revealed extensive thrombosis in widened veins. Clinical improvement occurred following adequate thrombolysis. Congenital absence of the vena cava inferior results from aberrant development during organogenesis. Patients are typically asymptomatic, but may present with venous insufficiency at a young age and deep vein thrombosis. Absence of the vena cava inferior can be accompanied by other congenital abnormalities such as dextrocardia and congenital heart diseases. Diagnosis is made using CT or MRI. Treatment consists of lifelong anticoagulant therapy and, if necessary, surgery.

Purpose: To determine if using CIE L*a*b* color measurements of white facial skin could be correlated to those of silicone shade samples that visually matched the skin. Secondly, to see if a correlation in color measurements could be achieved between the silicone shade samples and duplicated silicone samples made using a shade-guide color formula., Materials and Methods: A color booth was designed according to ASTM specifications, and painted using a Munsell Value 8 gray. A Minolta colorimeter was used to make facial skin measurements on 15 white adults. The skin color was duplicated using custom-shaded silicone samples. A 7-step wedge silicone shade guide was then fabricated, representing the commonly encountered thicknesses when fabricating facial prostheses. The silicone samples were then measured with the Minolta colorimeter. The readings were compared with the previous L*a*b* readings from the corresponding patient's skin measurements, and the relative color difference was then calculated. Silicone samples were fabricated and analyzed for three of the patients to determine if duplication of the visually matched silicone specimen was possible using the silicone color formula, and if the duplicates were visually and colorimetrically equivalent to each other. The color difference Delta E and chromaticity was calculated, and the data were analyzed using a coefficient-of-variation formula expressed by percent. A Pearson Product Moment Correlation Coefficient was performed to determine if a correlation existed between the skin and the silicone samples at the p < or = .05 level., Results: The highest correlation was found in the b* dimension for silicone thicknesses of 1 to 4 mm. For silicone thicknesses of 6 to 10 mm, the highest correlation was found in the L* dimension. All three dimensions had positive correlations (R2 > 0), but only the 1-mm and 4-mm b* readings were very strong. Patient and silicone L*a*b* measurement results showed very little change in the a* axis, while the L* and b* measurements showed more change in their numbers, with changes in depth for all patient silicone samples. Delta E numbers indicated the lowest Delta E at the 1-mm depth and the highest Delta E at the 10-mm depth. All duplicated samples matched their original silicone samples to a degree that visual evaluation could not distinguish any color differences. Using volumetric measurements, a shade guide was developed for all 15 patients., Conclusions: There was good correlation between the patient's colorimeter measurements and the silicone samples, with the b* color dimension the most reproducible, followed by the L* and the a*. Silicone samples at 6, 8, and 10 mm matched the patient the best, and this study showed that silicone samples can be duplicated successfully if a good patient-silicone match is obtained. Rayon flocking fibers and liquid makeup are effective at matching facial prostheses and can be used to develop a simple shade guide for patient application.
