Conditions

Edentulous Alveolar Ridge

Keywords

Brief summary

in this study we will construct denture for patient by different way and material one of this denture constructed digitally and the other one constructed in conventional way with metal reinforced. then we will measure the retention of the dentures

Detailed description

the complete denture is constructed for completely edentulous patient. the different technique of construction aim to increase retention of denture to prevent dislodgment during mastication

Design outcomes

Primary

MeasureTime frameDescription
retention measurementimmediatlly after denture constructionTo assess retention, a digital force gauge (Digital Force Gauge EXTECH 475044) was employed. All of the mandibular dentures were modified to receive a custom-made metal framework consisting of three tubes connected by a hook at the determining geometric center of the denture, two tubes extend 2 cm above the occlusal plane from the retromolar pad region, and one was made at the midline region lingual and below the central incisors. The mandibular denture's polished surface was then joined to the specially constructed custom-made metal framework using self-curing acrylic resin
