NCT05468983

Brief Summary

The biggest challenge of oral rehabilitation is the replacement of lost structures and the restoration of their function and esthetics, focusing on matching a healthy tooth. Traditional complete dentures, implant (retained, supported) overdentures, and complete implant-supported fixed prostheses are all alternatives to the rehabilitation of the mandibular arch. The aim of this study was to compare BioHPP used as a skeletal substructure for hybrid (implant fixed, detachable) prostheses versus BioHPP bar supporting and retaining by using radiographic tracing to the marginal bone height changes around the implants, patient satisfaction can be improved.

Outcome Measures

Primary Outcomes (1)

  • bone height change around implants

    The bone loss measurements were taken using a digital preapical radiograph as follows: Two horizontal lines were drawn at the alveolar bone crest and the implant apex; the software then automatically displays the measurements in millimeters between the two lines on the screen. Subtraction was used to compute the difference in bone height. The mean of the mesial and distal readings was calculated. The software then displays the measurements in millimeters between the two lines on the screen. At each follow-up visit, the values of linear measurements were recorded in the patient's chart, and the mean value of bone height change was calculated using this data.

    from insertion ( base line) to 6 months ) , from 6 months to 12 months ,from 12 months to 18 months , from insertion to 12 months, from insertion to 18 months

Secondary Outcomes (1)

  • patient satisfactions

    6 months and 18 months

Study Arms (2)

BioHpp hybrid prosthesis( fixed )

OTHER

4 implants were placed in the mandibular arch by a surgical guide, after 3 months the final prosthesis was constructed by using a digital workflow( CAD-CAM )

Procedure: surgical ( implants placement)

Eligibility Criteria

Age55 Years - 65 Years
Sexmale(Gender-based eligibility)
Gender Eligibility DetailsAll selected patients were healthy to minimize gender difference and to avoid the sex-related hormonal changes that accompany the menopausal and post-menopausal periods in females, which might affect the rate of alveolar ridge resorption
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • sufficient inter arch distance. 2. good oral hygiene. 3. Enough bone volume in interforaminal region.

You may not qualify if:

  • TMJ disorders.
  • Radiotherapy or chemotherapy.
  • Diabetes mellitus
  • Uncooperative patients
