Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aimed to evaluate the use of computer added designning / computer added manufacturing (CAD/ CAM ) technology versus conventional relining procedure for treating ill-fitted loose maxillary complete denture and its effect on patient satisfaction, denture retention, and denture adaptation to oral tissues.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Twelve edentulous patients suffering from loose maxillary complete dentures were selected, the dentures were adjusted for taking the relining impressions, the impressions were scanned and the STL files were used for milling new dentures (Group A), then the relining impression went through the conventional laboratory steps of processing (Group B). Both groups were evaluated regarding patient's satisfaction by a specially designed questionnaire, retention values were measured by a digital force gauge at denture insertion appointment and two weeks later, finally dentures adaptation to the oral tissues were compared using geomagic software.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
