Retention, stability & support are three important factors which determine the basic objectives, success and comfort of any removable prosthesis.In acquired surgical maxillary defects; the degree of impairment, size and location of the defect influences the outcome of the overall prosthetic overhaul.Prosthetic therapy with obturator closes the defect by re-establishing the oro-nasal separation, thereby, improving deglutition, speech and hypernasality. After maxillectomy, 3-6 months after surgery,patients with class 4 maxillary defects complains of frequent loosening of temporary prosthesis due to more amount of tissue changes, dimensional stabilization of surgical site, more loss of mucogingival support and rapid healing changes. As a result, there is an every chance of endangerment with the use of temporary prosthesis and allow the patients in seeking the definitive prosthesis over interim prosthesis. In this regard, designing of cast partial metal frame work with linear configuration for class 4 maxillary defects enhances the quality and comfort of the definitive prosthesis over conventional acrylic prosthesis. This article mainly describes the fundamental designing technique in improving the retention, stability and support of the definitive prosthesis with cast retainers.

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.

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.
