“…The fact that posterior palatal seal plays an important role in enhancing the retention and stability of complete maxillary denture is well recognized. 2 , 3 By providing intimate contact with the posterior palatal tissue, it reduces the gagging reflex. Further, it partly compensates for the palatal discrepancy occurring as a result of curing shrinkage of acrylic resins.…”

AimTo evaluate retention of complete denture base with different types of posterior palatal seals.Material and methodsTen male patients between the age group of 50 years to 60 years were selected for the study. After the primary and secondary impressions were taken, five casts were made including a cast without posterior palatal seal, a cast with single bead posterior palatal seal, a cast with double bead posterior palatal seal, a cast with butterfly shaped posterior palatal seal, and a cast with posterior palatal seal with low fusing compound by functional method.ResultsIt was observed that retention increased up to 108% in the posterior palatal seal with low fusing compound with functional method and the posterior palatal seal that was obtained by using functional method provided greater retention than a denture base without posterior palatal seal.ConclusionIt was concluded that the incorporation of a posterior palatal seal is important for obtaining optimum retention of the maxillary complete denture.

“…It is worth noting that flow is a time-dependent phenomenon. 16,25 That is, the amount of separation of denture and mucosa that can occur depends on the duration of the application of any force. If a reseating force is applied before detachment has occurred, such as in chewing, the displacement will only be transitory and may never reach the point of collapse.…”

The purpose of this article is to assist the practitioner to understand which factors are relevant to complete denture retention in the light of the current understanding of physics and materials science and thus to guide design. Atmospheric pressure, vacuum, adhesion, cohesion, surface tension, viscosity, base adaption, border seal, seating force and muscular control have all been cited at one time or another as major or contributory factors, but usually as an opinion without proper reference to fundamental principles. Although there has been a detailed analysis published, it seems appropriate that a restatement of the points in a collated form be made. In fact, denture retention is a dynamic issue dependent on the control of the flow of interposed fluid and thus its viscosity and film thickness, while the timescale of displacement loading affects the assessment. Surface tension forces at the periphery contribute to retention, but the most important concerns are good base adaptation and border seal. These must be achieved if full advantage is to be taken of the saliva flow-related effects.
