Computer aided design and fabrication of a pediatric fox plane in PLA: A case report

Title: Computer aided design and fabrication of a pediatric fox plane in PLA: A case report

Abstract:

Because of the loss of teeth, all the manducatory functions are affected: phonation, swallowing and mastication, which generates several disorders and parafunction that affect the physical growth and maturation of the patient, in fact, the alteration of aesthetics degrades the image of the child of himself, especially as the infant environment to which he adheres (friends, neighbors and classmates) does not assimilate the early loss of teeth making schooling of these young patients difficult. As a result, the dentist participates not only as such but also as a therapist to facilitate the integration of the new prosthesis. Prosthetic management in children and adolescents is complicated by the reduction of the perimeter of the mouth, the importance of the psychological approach to facilitate the patient/practitioner exchange, but also the high esthetic expectations of the patients. the case of our patient where the alteration of the general state affects the oral anatomical elements. Auto-immune lymphoproliferative syndrome (ALPS) is benign, early-onset (on average before five years), combines multifocal lymphadenopathy, splenomegaly and possibly hepatomegaly; This multi-organ involvement is reflected by an alteration of all the manducatory functions of the affected patients, but xerostomia, immunosuppression, and hypofibrinogenemia reduce the quality of osteomucosal bearing surfaces; in addition to the low salivary viscosity, retention and prosthetic stability become a real challenge. In some more complex cases, where age (13years) and microstomia added to the arsenal of challenges, it becomes necessary to adapt the instruments to reduced pediatric dimensions. The objective of this work is to demonstrate through a clinical case the prosthetic management of a patient suffering from this syndrome, through the computer-aided design and manufacturing of an individualized Fox plan according to patient’s proportions made in PLA (polylactic acid) to adjust the occlusion plane appropriately.
