Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 45 to 70 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • • Patients were healthy and free from all systemic diseases that affect osseointegration or bone resorption around the implant as recorded from medical and dental history.
  • Patients were free from all oral pathological conditions and any remaining roots which were verified by pre-operative panoramic radiograph.
  • Patients with U shaped arch, flat mandibular alveolar ridge covered with even compressibility healthy mucosa and gingival thickness of about 2mm verified by dual scan of cone beam computed tomography (CBCT) during treatment planning. Fig.(1)
  • Adequate residual alveolar bone quality D2 bone type in the anterior and premolar regions according to the Misch bone density classification scheme (850 to1250 housefield units) confirmed by CBCT.
  • Angel's class I maxillomandibular relation with moderate inter- arch space (20 mm) confirmed through tentative jaw relationship, and restorative space of at least 15 mm determined by putty index technique
  • Patients complain from poor retentive mandibular denture seeking for alternative fixed options.
  • Patient who is motivated, agreed with the follow-up visits and willing to return for follow-up appointments.

Who cannot join

  • • Patient with absolute contraindications that interfere with surgical placement and osseointegration of implants as uncontrolled diabetes mellitus, generalized osteoporosis, recent myocardial infarction, patient with radiotherapy.
  • Patient with relative contraindication such as UN controlled diabetes mellitus, moderate smoking and alcoholism, patient with TMJ disorder and heavy smokers for more than10 cigarettes per day.
  • Patient with local contra indication as insufficient bone quality, localized lesion in canine area and premolar area, unfavourable position of the lower alveolar or mental nerve, bone defects as verified by cone beam CT.
  • Uncooperative patient.

Questions about this trial

What is this clinical trial studying?

A study testing implant casts fabrication in people with Prosthesis Durability, 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 7 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 20 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?

Results are not available in the source record.

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?

accuracy of 3D printed casts (time frame: 6 month). 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 20 Dec 2023.
