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.

Background: Virtual surgical planning (VSP) with simple cutting templates could help surgeons preoperatively plan scapula reconstructions in the vertical and horizontal orientations.
Methods: Virtually, eight defects were created in ten healthy mandibles and reconstructed with the subject-specific scapula vertically and horizontally. In the clinical series, 15 single-piece scapula mandible reconstructions planned with in-house VSP and guided with simple templates were compared with 15 freehand reconstructions.

The anatomical location of certain lesions can be a difficulty when locating them intraoperatively. The use of surgical navigation allows anatomical structures to be located with great precision. However, there are technical difficulties with its use in mandibular surgery.

Aims: Bone preservation is a requirement for long-term stability of dental prostheses, which is all the more important in the posterior mandible, given the particular challenges these areas pose to prosthetic treatment. The objective was to investigate the implications of different prostheses on the atrophy of posterior alveolar bone after tooth loss.
Materials And Methods: A total of 457 treatment cases were retrieved from the medical documentation and information network.

Background: The continuous development in digital prosthodontics allowed the customization of attachments and retentive inserts which offers an easy and cheap solution for regular maintenance of locator overdentures during daily practice. The present study compared the change in retention values of the fully digitally manufactured custom-made locator attachment retentive insert with the ready-made ones after insertion, removal, and masticatory cycles.
Methods: A complete denture was constructed over a mandibular edentulous epoxy model.

Statement Of Problem: Intraoral scans can be articulated in maximum intercuspal position (MIP) by using an artificial intelligence (AI) based program; however, the impact of edentulous areas on the accuracy of the MIP located using this AI-based program is unknown.
Purpose: The purpose of this in vitro study was to assess the impact of edentulous areas (0, 1, 2, 3, and 4 posterior mandibular teeth) on the accuracy of the MIP located using 3 intraoral scanners (IOSs) and an AI-based program.
Material And Methods: Stone casts articulated in MIP in an articulator were digitized (T710).
