Although various methods have been applied for getting a Complete Denture with perfect retention, but it is difficult to attain. Residual ridge resorption creates an ill-fitting denture, hence causing difficulty while eating and even dislodging during talking, even adding to the patient's embarrassment. Suction cup has been widely used for the retention & stability of dentures, but is known to carry few complications like palatal perforations and oro-antral communications. Here we present a case report of palatal hyperplasia due to the suction cup.

The retention, stability and comfort of wearing denture is greatly influenced by the flow, quantity and consistency of saliva. Insufficient salivary output results especially in old-aged edentulous patients may result in denture sores because of lack of lubrication by saliva, thus, reducing patient’s ability to retain the prosthesis. Various approaches have been concernes with the use of reservoir with holes have been described in the literature. However the flow of salivary substitute is very difficult to control. Moreover the frequent cleaning of the denture required to maintain the patency of the reservoir holes poses various challenges to the patient. This article explains a novel technique for the incorporation of a reservoir with controlled salivary flow in complete denture to enhance the retention of the prosthesis and thus, improving the comfort of wearing denture and the speech of patient.

Denture teeth and denture flange are two very important aspects of a complete denture. For aesthetic purpose while fabricating the complete denture prosthesis, restoring the labial fullness is a sensitive procedure. There are some clinical situations where the labial flange gives poor facial aesthetics. It is more occur in proclined maxillary anterior ridge or thick labial cortical plate with severe labial undercut. In this article we are presenting a case with thick labial cortical plates and severe labial undercut. So, we have modified the complete denture and delivered a prong (flangeless) denture to give more aesthetic appearance to the patient.

Mandibular ridge resorption is a biomechanical and a complex disease that brings about chronic, progressive, cumulative and irreversible changes in bone structure resulting in severe impairment in fit and function of prosthesis. Some common hormonal, neurological, metabolic disorders can affect the adaptability of denture which can be diagnosed by a trained prosthodontist with proper history taking and clinical examination. If a denture stays inside or outside of the neutral zone, it will be unstable during functional & physiological activities such as talking, swallowing and mastication. Neutral zone technique is a long being used for the management of severely resorbed mandibular ridge. Various materials can used in recording neutral zone which have their own advantages and disadvantages. This technique serves as an alternative approach for the construction of mandibular complete denture. This technique is most effective for denture where there is a highly atrophic ridge, neuromuscular incoordination and history of denture instability. This clinical report describes in detail the fabrication of a complete denture in a patient with poorly formed mandibular ridge using neutral zone technique with addition of cast metal in mandibular denture for extra stability.
