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.

Traumatic injuries leading to severely mutilated anterior teeth are common in dentistry. These injuries may leave a severe impact when they affect endodontically treated teeth as strength of such teeth is compromised. Proper functional and esthetic rehabilitation of such badly broken teeth is a challenge. Dealing with the patient's mental suffering and their impatience to regain the natural smile back makes the treatment even more challenging. An effective treatment plan including a suitable and cost-effective choice of post is very much necessary in such conditions. Biological posts obtained through extracted teeth from another individual represent an economic option and alternative technique for the functional recovery of extensively damaged teeth. All-ceramic crowns further add to enhanced esthetics. This paper presents a case where biological posts with composite core build up followed by all-ceramic crown adaptation have been used with successful outcome.
