Clinical Trial Summary

This clinical study aims to evaluate the effect of using PEKK (Pekkton) framework in mandibular implant-supported complete fixed dental prostheses with All-on-four treatment concept on peri-implant tissues health

Description:

The aim of this clinical study is to evaluate the effect of using PEKK (Pekkton) framework in mandibular implant-supported complete fixed dental prostheses with All-on-four treatment concept on peri-implant tissues health regarding the following parameters:

• Modified Plaque index

• Modified Gingival index

• Peri-implant probing pocket depth

Radiographic evaluation (periapical x-ray):

Marginal bone height changes

Recruitment information / eligibility

• Status: Completed
• Enrollment: 16
• Est. completion date: November 10, 2023
• Est. primary completion date: June 15, 2023
• Accepts healthy volunteers: Accepts Healthy Volunteers
• Gender: All
• Age group: 50 Years to 70 Years

Eligibility

Inclusion Criteria:

• Maxillary and mandibular alveolar ridges were covered with healthy, firm, relatively even thickness and even compressible mucosa and free from any signs of inflammation or flabbiness.

• Patients had completely edentulous maxillary and mandibular ridges with sufficient mandibular bone height not less than 15 mm in the interforaminal area and at least 12mm posteriorly

• All patients had sufficient inter-arch space

• All patients complained of insufficient retention and stability of their conventional mandibular dentures.

• All patients were of Angel's class I maxillo-mandibular relationship.

Exclusion Criteria:

• Patients with absolute contraindications for implant placement, such as active cancer and diseases of the immune system.

• Patients with metabolic diseases that are directly related to bone resorption, such as uncontrolled diabetes, osteoporosis, and hyperparathyroidism.

• Patients with general contraindications for surgical procedures, such as hematologic diseases, hepatic patients, patients with bleeding disorders, and serious problems with coagulation.

• Patients with a history of irradiation of the head and neck region or chemotherapy in the last 3 years were also excluded.

• Patients with relative contraindications such as a history of parafunctional habits (such as bruxism and clenching), smoking, alcoholism, and patients with any physical reasons that could affect follow-up.

• Patients with local contraindications for implant placement, such as localized bone defects.
