Abstract
Complete dentures play an essential role in restoring oral function and improving the quality of life for individuals who have missing all their normal teeth. One of the key factors determining the success of complete dentures is their retention, which refers to the ability of dentures to stay securely in place during normal oral function. Adequate retention is essential for proper speech, mastication and overall comfort of the denture wearer. The study aimed to improve the retention of complete dentures through three different approaches: spacer, posterior palatal seal area, and undercut area. Three dentures were fabricated using the same steps, with variations in certain steps based on the retention technique being employed. The study showed that all three dentures had improved retention compared to standard complete dentures. The dentures that included the posterior palatal seal area and spacer demonstrated higher retention than the denture that employed the undercut technique. It is worth noting that the patient did not find the denture with the undercut technique satisfactorily.
