Summary
This studies aims to compare the behavior of recently introduced resin reinforces compared to monolithic zirconia
Eligibility
Inclusion Criteria9
- Mandibular Class II, partially edentulous patients that enables measuring the marginal bone height changes and values of biting forces intra-orally.
- Fully dentulous edentulous opposing Maxillary arch.
- Patients with normal class I jaw relationship.

- Age range (30-60 years).
- Cooperative patients those are willing to attend all follow-up periods.
- Patients with healthy attached mucosa of appropriate thickness free from any inflammation.
- Patients with healthy bone of appropriate thickness, width and height free from any inflammation.
- Patients without any medical conditions that contraindicates implant placement.
Exclusion Criteria8
- Patients with Parkinson's disease
- Patients with xerostomia.
- Patients with a history of allergy to resins and/ or zirconia.
- Patients with a medical systematic condition that contraindicate implant placement.
- Patients smoking more than 10 cigarettes per day.
- Patients with pathological changes of residual ridges as recurrent or persistent ulcers, osteomyelitis and infections.
- Patients with large irregular bony exostosis.
- Patients with medical or psychological conditions as physical disability or mental retardation that hinder cooperation in the follow up visits and answering the questionnaires.

Interventions
A comprehensive clinical examination with an understanding of patients' chief complaints and needs will be carried out. For each patient, two implants will be placed in the edentulous area, and the patient will receive a screw-retained bridge supported by both implants made of milled monolithic zirconia (Dental Direkt Zirconia, Germany). After 6 months, the zirconia restoration will be replaced with a milled resin-reinforced composite (Nanoska G Plus, USA), allowing the same patient to use the new restoration for another 6 months. Randomization will be performed to determine the sequence of bridge material for each participant. Accordingly, the two restorations will be sequentially delivered to each participant with no gap (wash-up period) between them. Consent will be signed by the selected participants after explaining the detailed information of the trial.
