NCT06176014

Brief Summary

the purposse of the study To evaluate the effect of implant supported hybrid prostheses on the bone of the supporting structure of edentulous mandible using Polyetherketoneketone (PEKK) framework versus cobalt chromium framework. fourteen female patients with lower single edentulous ridges are chosen with adequate dental hygiene, enough interarch space and free of systemic diseases and parafunctional habits. Patients who received new single dentures are randomly allocated into each group using computer software program and five intraforaminal implants were inserted parallel using surgical guide.

Outcome Measures

Primary Outcomes (1)

  • amount of bone loss around implant

    The points of first bone contact with the fixture platform were detected and changes of those points position through the two years of observation were registered as a criterion of bone changes with further calculation of average values. A software ruler of CBCT was used to measure the crestal bone height in contact with the implant from the four aspects (buccal, lingual, mesial and distal).

Study Arms (2)

(PEKK fixed hybrid prostheses

OTHER

5 implants were placed in mandibular arch by surgical guide and after 3 months the prostheses was constructed by using digital workflow

Procedure: implant placement

PFM fixed hybrid prostheses

OTHER

5 implants were placed in mandibular arch by surgical guide and after 3 months the prostheses was constructed by using digital workflow until making wax pattern the casting was made.

Eligibility Criteria

Age50 Years - 60 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Patient's age range from 50 to 60 year's old.
  • All patients are with completely edentulous mandible.
  • Good oral hygiene is mandatory.
  • Sufficient interarch space to accept implant supported fixed prosthesis will be diagnosed by mounted diagnostic casts.
  • Firm and healthy mucosa covering the alveolar ridge.

  • Patients with Para functional habits.
  • Patients having TMJ disorders.
  • Uncontrolled diabetic patients
  • Patients have any medical condition or any disease that could interfere with implant placement or affect bone loss.
