| Label | Type | Description | Intervention Names |
|---|---|---|---|
| cobalt-chromium framework partial dentures | Active Comparator | It's the gold standard biocompatible metal alloy used in thin sections, provide high strength and stiffness ,conduct heat and cold for a more natural experience, and is resistant to corrosion but their disadvantages include esthetic issues with metal display, oral galvanism, adverse tissue reactions,and osteolysis of abutment teeth. |
|
| PEEK framework partial dentures | Experimental | It's a promising polymer-based framework has recently been introduced which is made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| cobalt-chromium framework partial dentures | Device | 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 . |
| Measure | Description | Time Frame |
|---|---|---|
| Periodontal status | periodontal status of the abutment teeth assessed by a periodontal chart . | Change in periodontal status will be assessed at base line , after one month and after 3 months . |
