About this study

Official title: Effect Of Occlusal Materials Used For All On Four Implant Supported Mandibular Fixed Prosthesis With PEEK Framework

This study was performed to compare between the effects of different occlusal materials used for all on four implant supported mandibular fixed prosthesis with PEEK framework.

Methods of Evaluation

1- Occlusal force analysis using digital occlusal device (occluscan).

The evaluation periods will be done at time of insertion (T0),6 month (T1),12 month(T2) and 18 month(T3) after framework insertion.

Read the detailed description

thirty completely edentulous patients will be selected for the study from the outpatient's clinic of Prosthodontic Department, Faculty of Dentistry, Mansoura University.

The patients will be selected according to the following criteria:

  1. lack of satisfaction of mandibular conventional dentures due to denture instability.
  2. Atrophy of mandibular ridges with insufficient bone.
  3. They were healthy, free from any systemic diseases relating to bone resorption.
  4. All patients have sufficient inter-arch space >15 mm.
  5. Maxillary and mandibular residual alveolar ridges covered by healthy non-inflamed mucosa with even compressibility.
  6. Normal maxilla-mandibular relationship (class I Angle's classification).
  7. All patients will have mandibular bone height not less than 8-10mm as verified by cone beam CT.
  8. Sufficient inter-arch space not less than 23 mm as verified by tentative jaw relation. And restorative space not less than14 mm as verified by putty index technique.

Exclusion criteria included:

1- Systemic disorders affecting bone (such as uncontrolled diabetes mellitus and osteoporosis).

2- Local or general contraindication for surgical procedures. 3- History of chemotherapy or radiation therapy to the head and neck area. 4- Habits as heavy smoking and alcoholism. 5- Patients with T.M.J disorders or poor neuromuscular co-ordination.

  1. For all patient's conventional complete denture will be constructed and adjusted for insertion and delivery.
  2. A cone beam C.T will be done for each patient to determine the bone quality and quantity.
  3. A surgical stent will be designed and fabricated to allow accurate implant placement of two axially placed anterior implants and two distally tilted posterior implants by about 30 degree to support mandibular overdenture.
  4. Surgical placement of implant fixtures on its sites will be done.
  5. Multiunit abutments were screwed to the distal implants.
  6. The conventional mandibular denture will be modified to act as immediate fixed prosthesis that replace lost teeth and gingival tissues.
  7. After three months, the Polyetheretherketone (PEEK) frame that connects the four implants will be constructed using digital scan and CAD CAM manufacturing.
  8. The milled frame was fixed to the metal caps using DTK cement
  9. The BioHPP framework will have prepared abutments projecting from it. After processing, the framework will be tried in patient mouth for passive fit.
  10. Wax interocclusal record was made to establish the occlusal relationship with opposing teeth. According to the artificial teeth, the patients will be divided into two groups:
  • Group (I): PEEK framework veneered with nanocomposite resin(visio-lign)
  • Group (II): PEEK framework veneered with zirconia
  1. The inner surface of the artificial teeth will be etched using hydrophosphoric acid then silane will be used and light cured resin cement will be used for cementation of the artificial teeth to the PEEK framework
  2. The occlusal scheme used with the opposing maxillary denture will be lingualized balanced occlusion to enhance the stability of mandibular implant overdentures.

Methods of evaluation:

1- Occlusal force analysis using digital occlusal device (occluscan).

The evaluation periods will be done at time of insertion (T0), 6 month (T1), 12 month (T2) and 18 month (T3) after framework insertion.

Questions about this trial

What is this clinical trial studying?

A study testing dental implants, peek framework and visio-lign nano composite in people with Occlusal Trauma, run by Mansoura University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

occlusal stability (time frame: The evaluation periods will be done at time of insertion (T0), 6 month (T1), 12 month (T2) and 18 month (T3) after framework insertion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Dec 2023.
