Prosthodontic rehabilitation of hereditary ectodermal dysplasia in an 11-year-old patient with flexible denture: a case report

Rehabilitation Considerations for Very Young Children with Severe Oligodontia due to Ectodermal Dysplasia: Report of Three Clinical Cases with a 2-Year Follow-Up

Introduction

Management of oligodontia can be complicated and requires multidiscipline care, involving a wide spectrum of interventions. The aim of this report is to describe the challenges of oral rehabilitation of three very young children with oligodontia. Report. Three preschool aged Caucasian males, diagnosed with ectodermal dysplasia, were treated with interim removable dentures in order to replace missing teeth, reclaim vertical dimension, and improve function and aesthetics. The main challenges faced were patient cooperation, dental and skeletal characteristics, and parental expectations. Two years post-treatment, both patients and parents reported excellent adaptation to prosthesis and satisfaction with aesthetics.

Conclusion

Rehabilitation of oligodontia may be challenging due to accompanying oral findings, dentofacial growth considerations, and behavioral issues. Establishment of good rapport between patients, parents, and clinician is the key for the success of the treatment even with the use of nonpharmacological behavioral management techniques.

Nonmetal clasp dentures: What is the evidence about their use?

The aim was to discuss the indications, contraindications, advantages, and disadvantages of Nonmetal clasp dentures (NMCDs), as well as the most relevant properties of its constituent materials. A search was conducted using the keywords: “nonmetal clasp dentures,” “thermoplastic resin,” “flexible resin removable partial denture,” “polyamide,” and “nylon” in databases PubMed/Medline, Lilacs, SciELO, and textbooks between 1955 and 2020. Theses and texts without reliable sources of publication were excluded. Once the analysis instruments were determined, the data were analyzed and discussed. NMCDs present high flexibility, easy adaptation to the abutments, color compatibility and biocompatibility with the oral mucosa, and absence of visible metal clasps. However, they need laboratory relining, grinding, and polishing, do not have criteria for its planning, become rougher and stained over time, and are able to traumatize supporting tissues. The association with metal components seems to be an alternative to increase the success of NMCDs by combining esthetics and biomechanical principles of conventional removable partial dentures. The lack of long-term clinical studies makes the professionals to rely solely on previous experiences or on the manufacturers' recommendations. It suggested that NMCDs must be indicated with caution when not used temporarily.

Prosthodontic Management of a Pediatric Patient with Christ-Siemens-Touraine Syndrome: A Case Report

Ectodermal dysplasias (ED) are a group of rare genetic disorders characterized by congenital defects involving two or more ectodermal structures. Christ-Siemens-Touraine syndrome or hypohidrotic ectodermal dysplasia is the commonest form of ED. Hypohidrotic ectodermal dysplasia (HED) is an X-linked disorder characterized by excessively dry skin due to the absence of sweat glands (anhidrosis), sparse body hair especially on the scalp and eyebrows (hypotrichosis), brittle nails, absence of sebaceous glands (asteatosis) and malformed or absent teeth. Oral manifestations include oligodontia or complete anodontia, conical teeth, underdeveloped alveolar ridges, generalized spacing and delayed eruption of permanent teeth. This case report discusses a classical case of HED and the options for rehabilitation in a growing patient. A thorough knowledge about the clinical manifestations of ED will lead to proper diagnosis and appropriate treatment plan thereby leading to significant improvements in esthetics, phonetics and masticatory function in ED patients, which in turn leads to improved quality of life in these individuals.

Conventional Complete Denture in Patients with Ectodermal Dysplasia

Ectodermal dysplasia is described as heritable conditions that involve anomalies of structures derived from the ectoderm, including hypodontia. In the cases of edentulous young patients, who did not finish their craniofacial growth, treatment with conventional complete denture is a suitable alternative. The aim of this study was to report a case of mandibular edentulism treated with conventional complete denture in a thirteen-year-old patient diagnosed with hidrotic ectodermal dysplasia. Typical features, such as frontal bossing, depressed nasal bridge, protuberant lips, scarce hair, and brittle nails, were visualized during the extraoral examination. The intraoral inspection and radiographic analysis revealed oligodontia, dental malformation, and prolonged retention of deciduous teeth at maxilla and total edentulism at mandible. A conventional complete denture was planned and constructed following the same steps of technique as recommended in adults. Although this option is not a definitive treatment, the patient and his parents were satisfied with his improvement in chewing and speech, as well as with the aesthetic benefits.

Prosthetic rehabilitation of acquired maxillary defects secondary to mucormycosis: clinical cases

Maxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections, such as herpes zoster or fungal infections, such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fungal infection, which mainly infects immunocompromised patients. Once the maxilla is involved, surgical resection and debridement of the necrosed areas can result in extensive maxillary defects. The clinician is to face many a challenge in order to replace not only the missing teeth, but also the lost soft tissues and bone, including hard palate and alveolar ridges. The prosthesis (Obturator) lacks a bony base and the lost structures of the posterior palatal seal area compromise retention of the prosthesis. Furthermore, the post surgical soft tissues are scarred and tense, which exert strong dislodging forces. The present article describes the prosthetic rehabilitation of maxillary necrosis secondary to mucormycosis in two cases, one completely edentulous and the other partially edentulous.
