Interim three-dimensional printed overlay prosthesis for an adolescent patient with oligodontia

Abstract

Oligodontia is a developmental anomaly which represents the congenital absence of more than six teeth in primary, permanent, or both dentitions and may or may not be associated with a syndrome. These patients suffer from occlusal disharmony, problems in speech and esthetic appearance. A multidisciplinary approach becomes mandatory to manage such patients to rehabilitate their oral function. Therefore, early diagnosis and treatment become important. This is a case report of a 15-year-old female patient with oligodontia, who was rehabilitated with removable overlay prostheses fabricated digitally, without modifying her existing dentition, to restore mastication, phonetics, and esthetics. Such an approach is essential for children who have not completed their growth. The monolithic three-dimensional (3D) printed denture has increased fracture resistance and higher wear resistance compared to conventional denture. It can also be easily adjusted, repaired and if required, reproduced. This article highlights the methodology, pros and cons of fabricating 3D printed dentures for such patients.

“…Additionally, 3Dprinted surgical guides help safely extract deeply impacted supernumerary teeth [15]. Their usefulness extends to effective prosthetic treatment of school-age students with oligodontia [16] and for the testing of fracture resistance of zirconia crown restorations with additional post [17]. It applies to or-thodontic interventions, especially beneficial for patients who have difficulty producing alginate impressions.…”

“…These RSMs can be made from materials such as poly methyl methacrylate (PMMA) or acrylic resin, which are lightweight and provide stable results [16]. In case of any growth-related changes, 3D-printed RSMs offer added flexibility as they can be easily trimmed, adjusted, relined, or even reprinted since digital files are readily available [19].…”
