Using Digital Technology Versus Conventional Relining Procedure for Correction of Loose Maxillary Complete Denture

Inclusion Criteria: * Patients with completely edentulous maxillary and mandibular ridges with a normal skeletal relationship (class I) have a moderate-to-highly well-rounded maxillary edentulous ridge without severe undercuts to minimize the effect of undercuts on retention values. * Patients' main complaint was a loose or "falling" denture, but with proper esthetics, centric relation and the correct vertical dimension of occlusion (VDO). Exclusion Criteria: * Patients with significant skeletal problems (class II or III) or who went through severe osseous surgery or any hereditary or acquired osseous abnormality find it challenging to place the denture properly on the supporting ridge. * If the patient suffers from xerostomia, excessive flabby ridges, any pathology of the oral mucosa, or any inflammatory changes, candidiasis, hyperplasia, neurological disorders and malignancies * If the denture creates a major speech problem, poor esthetics, or an unsatisfactory jaw relationship.
