Abstract

The durability and long term performance of a Fixed Partial Denture (FPD) largely depends on the type of occlusal relationship, area of missing teeth, distribution of stress, alveolar bone loss and condition of the periodontium. The prosthetic reclamation of a posterior FPD with pier abutment is always considered as a challenging task for a dentist due to frequent fracture of posterior FPD in connector region during functional occlusal loading. The frequent use of rigid connectors in day to day practice in such situations results in failure and instability of the prosthesis. In pier abutment areas, replacement of rigid connectors with non rigid connectors during fabrication of an FPD makes a huge difference in the long term mechanical behaviour of posterior fixed dental prosthesis. So, depending on the clinical scenario, accurate prior selection of type of connector by dentist makes the real difference in the overall prosthetic overhaul of the prosthesis. This clinical case report explains the simple basic technique of incorporation of non rigid connector to restore such cases. Keywords: Pier abutment, Connector, Retainer, FPD.

Abstract

Saliva is an important factor in determining the quality of retention in prosthetic management of edentulous conditions. Edentulism associated with multiple local conditions such as hypopigmentation, diabetes, Asthma, oral sub mucous fibrosis, multiple carious lesions etc results in decreased overall flow of salivary rate resulting in xerostomic condition. Due to this, lubricating capability of the saliva gets compromised resulting in loss of comfort and retention of removable dentures.To counteract this problem, numerous techniques have been proposed for incorporating reservoirs that contain salivary substitutes into dentures. This article describes the simplified prosthetic approach in constructing a properly functioning salivary reservoir denture to provide good lubrication to the tissues. Keywords: Reservoir denture, Retention, Xerostomia, Artificial salivary substitute.

Abstract

Weight is an important predetermining factor for surgical reconstruction of clefts in infants. These clefts causes’ difficulties in swallowing of milk leading to inadequate nutrition resulting in gradual loss of weight gain making surgical corrections difficult. Fabrication of artificial feeding plate prosthesis is the best alternative suggested treatment of choice in such situations. This prosthesis helps in proper devouring of the milk there by regaining required weight for surgical management of clefts. This article describes the simplified prosthetic approach in constructing a properly functioning feeding prosthesis and to reduce the parents’ anxiety originating from multiple dental visits. Keywords: Feeding plate, Obturator, Cleft lip, Cleft palate.
