About this trial

Partial dentures play a crucial role in restoring oral function and aesthetics for patients with missing teeth. Traditionally, these prostheses have been fabricated using materials such as acrylic resin or cobalt-chromium alloys. However, advancements in digital dentistry have introduced new materials and manufacturing techniques, including computer-aided design and computer-aided manufacturing (CAD/CAM) milled titanium. While titanium offers advantages such as biocompatibility, lightweight properties, and corrosion resistance, its impact on speech performance remains understudied.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Patients with Class IV Kennedy Classification partial edentulism.

Sufficient occluso-gingival height of its clinical crown

Full opposing arch or restored with acceptable restoration

Edentulous ridge covered by healthy firm muco-periosteum

Disqualifiers

without abnormal bony irregularity or sever lingual undercut

with no signs of mobility or inflammation with no tissue undercut

Patients with shallow floor of the mouth, prominent lingual tori, bony undercuts and lingual inclined teeth were all excluded

no tempro-mandibular joint disorders

Treatments tested in this trial

  • Removable Partial Denture

    Device

    A removable partial denture (RPD) is a dental prosthesis designed to replace one or more missing teeth in the mouth. Unlike full dentures, which are used when all teeth are missing, an RPD is specifically made for patients who still have some of their natural teeth remaining. It restores both function and aesthetics, allowing patients to chew, speak, and smile with greater confidence.

Treatment groups

12 Participants
are divided into 2 treatment groups
Group A: Conventional impression-based fabrication of cobalt-chromium frameworkActive comparator 1 intervention
Group B: CAD design, and CAM milling of titanium frameworkExperimental treatment 1 intervention

Trial outcomes

Primary outcomes

Speech analysis

Speech analysis refers to the systematic study and evaluation of human speech to understand various characteristics and functions related to sound production, articulation, and language. It is used in a wide range of fields, from linguistics and phonetics to medical and technological applications, such as diagnosing speech disorders and developing voice recognition systems.

Intelligibility test

An intelligibility test of speech is a method used to assess how well a person's speech is understood by others. It measures the clarity, precision, and comprehensibility of spoken words, focusing on how accurately listeners can interpret the speech without needing context or prior knowledge of the speaker\'s intent. Intelligibility tests are particularly important in diagnosing and evaluating speech disorders, assessing the effectiveness of speech treatments, and analyzing the impact of devices like dentures or hearing aids on communication.
