This study is aiming to evaluate the biting force of polyetheretherketone (PEEK) framework partial dentures compared to that of cobalt-chromium ones in mandibular Kennedy class I edentulous cases hoping that polyetheretherketone (PEEK) framework removable partial dentures can improve the patient masticatory efficiency .

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| PEEK framework partial dentures | Experimental | High performance ketone polymers introduced lately.These polymer-based frameworks provide better esthetics, higher elasticity, lighter in weight, have low water sorption and solubility, and are easily repaired and reproduced. |
|
| Cobalt-chromium framework partial dentures | Active Comparator | it is considered the gold standard framework. These frameworks are less bulky with high strength, conduct heat and electricity well, and have good durability. some disadvantages include hypersensitivity, adverse tissue reactions and bad aesthetics. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| PEEK framework partial dentures | Device | Polymer-based framework recently introduced made of polyetheretherketone polymer frame combined with acrylic resin denture teeth and a conventional acrylic resin denture base. |
| Measure | Description | Time Frame |
|---|---|---|
| Biting force | Biting force of the patient wearing the removable partial denture measured by I-load sensor device. | Change in baseline biting force from time of insertion, insertion after 1 month and after 3 months |

| Cobalt- chromium framework partial dentures | Device | It's a bio-compatible metal used in thin sections so 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 resistance to corrosion.Drawbacks of metal frameworks can include hypersensitivity, aesthetics because of metal metal display, oral galvanism, adverse tissue reactions, osteolysis of abutment teeth, and biofilm production |
