NCT06159530

Brief Summary

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.

Primary Outcomes (1)

  • occlusal stability

    Occlusal stability using digital occlusal device (occlusense)

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

Study Arms (2)

PEEK framework veneered with nanocomposite resin(visio-lign)

EXPERIMENTAL

patients recieved 4 implants according to All on 4 concept then peek framework was delivered and veneered with nano-composite resin (visio-lign) as an occlusal material

Eligibility Criteria

Age45 Years - 65 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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.
