What this trial studies

This clinical trial aims to evaluate the effectiveness of two types of fixed partial dentures—porcelain-fused-to-metal and zirconia—on biting force and patient satisfaction in individuals with partial edentulism. A total of thirty-three participants will be randomly assigned to receive either a cobalt chromium removable partial denture or one of the two types of implant-supported fixed partial dentures after a three-month osseointegration period. Biting force will be measured at various intervals, and patient satisfaction will be assessed through a quality-of-life questionnaire at the six-month follow-up. The study employs a rigorous methodology, including pre-surgical assessments and post-surgical follow-ups to ensure comprehensive data collection.

Who should consider this trial

Good fit: Ideal candidates include individuals with Kennedy Class II mandibular arch and sufficient bone height for dental implants.

Not a fit: Patients with bone or mucosal diseases, heavy smokers, or uncontrolled metabolic disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance patient outcomes by identifying the most effective type of dental restoration for improved biting force and satisfaction.

How similar studies have performed: Previous studies have shown promising results with similar approaches in dental implant restoration, indicating potential for success in this trial.

Eligibility criteria

Inclusion Criteria:

* Kennedy Class II mandibular arch where the last standing abutment is the first premolar, opposed by a fully dentate maxilla (either natural dentition or fixed prostheses).
* A minimum of 12 millimeters of bone height above the inferior alveolar canal diagnosed from the pre-operative cone beam CT.
* Sufficient inter-arch space to accommodate the implant supported fixed partial denture.

Exclusion Criteria:

* Patients with bone or mucosal diseases.
* Heavy smokers.
* Patients with uncontrolled metabolic disorders such as diabetes mellitus.
* Patients with parafunctional habits.
* Patients with conditions that might complicate the treatment, such as: severe gag reflex, limited mouth opening.
