“…[ 7 ] Extension of the lingual flanges of the mandibular denture to engage the sublingual undercut of the mandible was used and recommended as a mean to maximize retention of mandibular complete dentures. [ 11 12 20 21 ] While acrylic resin is the most commonly used denture base material, this study reported the use of flexible acrylic resin “Versacryl” to construct the lingual flanges of mandibular complete dentures. The flexible acrylic resin was introduced first in 1950 as an alternative to conventional acrylic resin denture base material.…”

“…One possible and simple way of enhancing denture retention is by extension of denture flanges to engage an existing soft-tissue undercut. [ 11 12 ] However, extension of conventional denture bases into soft-tissue undercuts should be kept minimal due to rigidity of acrylic resin. The introduction of resilient denture liners[ 13 ] and flexible acrylic resin[ 14 ] increased the chance for denture bases to be extended into deeper soft-tissue undercuts to gain further retention without risking the health of the supporting tissues or creating pain and difficulty during denture removal or insertion.…”

Objectives:The aim of this study was to compare the retention of conventional mandibular complete dentures with that of mandibular complete dentures having lingual flanges constructed with flexible acrylic resin “Versacryl.”Materials and Methods:The study sample comprised 10 completely edentulous patients. Each patient received one maxillary complete denture and two mandibular complete dentures. One mandibular denture was made of conventional heat-cured acrylic resin and the other had its lingual flanges made of flexible acrylic resin Versacryl. Digital force-meter was used to measure retention of mandibular dentures at delivery and at 2 weeks and 45 days following denture insertion.Results:The statistical analysis showed that at baseline and follow-up appointments, retention of mandibular complete dentures with flexible lingual flanges was significantly greater than retention of conventional mandibular dentures (P < 0.05). In both types of mandibular dentures, retention of dentures increased significantly over the follow-up period (P < 0.05).Conclusions:The use of flexible acrylic resin lingual flanges in the construction of mandibular complete dentures improved denture retention.

“…Tissue bounding this space moves freely, so that anterior lingual flange can be extended horizontally. 10,11,12 According to Glossary of Prosthodontic Terms, "sublingual crescent" is the crescent shaped area on the anterior floor of mouth formed by the lingual wall of mandible and adjacent sublingual fold. It is the region of anterior lingual sulcus.…”

“…In this case we didn't use patient's past denture because it was ill fitting and can't use an impression tray. The material of choice of sublingual crescent extension is modeling compound [4]. One requirement of the sublingual extension of the impression is to have minimal pressure exerted on the floor of the mouth with the tongue at rest.…”

“…It increases the tissue surface of the denture, augmenting simple adhesion and, therefore, retention. Krammer and Lawson [4,5] describe the principles and techniques of sublingual crescent extension and suggested its utilization in distal-extension highly compromized. Lewis ET [3] was first to report about the anterior sublingual area anatomy and utilization of sublingual crescent space for the retention of mandibular denture.…”

was instructed to gently place the tongue against the lingual side of tray handle. The tray was removed from mouth and cooled in cold water. This procedure was repeated until the sublingual crescent area was recorded satisfactorily. The impression compound was relieved in frenal notch area to expose the openings of sublingual ducts. The low fusing compound was carefully added along the borders of the recorded sublingual crescent in impression compound and patient was asked to repeat the same movement. The added sublingual crescent extension now maintains contact with the sublingual fold when tongue touches the lower lip ( Figure 5). It also maintains contact with floor of mouth even when tongue is in retracted position, thereby developing a good peripheral seal. Relief holes were made in the special tray and the secondary impression was made with zinc oxide eugenol impression paste ( Figure 6). Remaining steps were done in the conventional manner and the denture was fabricated in heat cure acrylic resin using long curing cycle (Figure 7).
