Abstract

India saw a devastating second wave of Coronavirus and along with the fatal nature of the disease the healthcare professionals saw a huge number of post Covid problems. One of these, is a fungal disease called mucormycosis which although an uncommon fungal infection can cause blackening of skin, redness, inflammation, sores and can encroach the eyes, lungs and even the brain. This warrants for extensive surgical resection and debridement of the necrosed areas resulting in maxillary and orbital defects. Intraoral defects in the maxilla cause communication with the nasopharyngeal complex. The surgically removed palate has a devastating effect on the appearance and speech of the patient. Obturator allows patients to eat and drink without letting the food to enter the oroantral cavities/ pharynx during mastication. This case series focusses on prosthetic rehabilitation of two patients with Hollow obturator post hemimaxillectomy in order to restore form and function.   Keywords: Post­Covid Mucormycosis, Hollow bulb Obturator, Maxillary defects

Abstract

The concept of Preventive Prosthodontics utilising conventional tooth-retained overdentures is a simple and cost effective treatment compared to implant overdentures. The concept of tooth supported overdentures is getting less popular because of advent of implant supported overdentures/hybrid dentures, but it is still utilised and provides a satisfactory means of rehabilitation and helps in delaying the process of residual ridge resorption and thus, helps in the preservation of bone, especially in patients who cant afford and/or cant undergo implant surgery because of health issues. A number of attachment systems are available for tooth supported overdenture treatment modality. The objective of all the systems is to provide retention and support for the overdenture, but the bar retained systems are expensive. This case report describes a simple and economic way of fabrication of a customised Hader bar using a simple coffee stirrer for tooth supported overdenture. Keywords: Customized Hader Bar, Tooth supported overdenture, Cast copings, Bar supported overdenture.
