About this study
Official title: Evaluation of Periodontal Health of the Abutment Teeth in Partial Dentures Made of Injection Molded PEEK Framework Versus Cobalt Chromium Framework in Mandibular Kennedy Class I Edentulous Cases
This study is aiming to evaluate the periodontal status of the abutment teeth in Polyetheretherketone ( PEEK ) framework partial dentures compared with cobalt-chromium ones in mandibular kennedy class I edentulous cases aiming to preserve the optimum periodontal health of the abutment teeth .
- Conditions
- Mandibular Prosthesis User
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cobalt-chromium framework partial denturesDevice
It's a biocompatible metal alloy used in thin sections and are less bulky, provide high strength and stiffness ,conduct heat and cold for a more natural experience, enable designs that minimize the covering of the gingival margins, allow for a stable denture base, and is resistant to corrosion. Disadvantages include hypersensitivity, esthetic issues with metal display, oral galvanism, adverse tissue reactions, osteolysis of abutment teeth, and biofilm production .
PEEK framework partial denturesDevice
It's a promising polymer-based framework material has recently been introduced which is made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base.

What is being measured
The primary outcome is the main question the study is designed to answer.
Periodontal status
periodontal status of the abutment teeth assessed by a periodontal chart .
Measured: Change in periodontal status will be assessed at base line , after one month and after 3 months .

What does the primary outcome measure?
Periodontal status (time frame: Change in periodontal status will be assessed at base line , after one month and after 3 months .). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03777345, which also lists 1 linked publication.
