Brief Summary

The aim of the present study will be clinical and radio graphical comparison of four basal and compressive implant designs will be installed in the interforamina area of atrophied edentulous mandible and immediately loaded by screw retained mandibular overdenture . Implant design comparison will be done clinically and radiographically after one and two years of implant loading

Conditions

Dental Implant Bone Loss; Peri-Implant Health

Keywords

Basal compressive implants; complete overdenture for atrophied edentulous mandibular ridge: Clinical and radiographic study

Outcome Measures

Primary Outcomes (3)

• Peri-implant tissue health

  Peri-implant tissue health that will be measured according to mombelli for both groups

  Baseline, 6 months, and 12 months after implant loading.

• Marginal bone height changes

  Marginal bone height changes will be measured using standardized digital panoramic x-ray for both groups

  Baseline, 6 months, and 12 months after implant loading.

• Implant stability

  Periotest will evaluate the stability of the implants during implantation for both groups

  Baseline, 6 months, and 6 months after implant loading.

Study Arms (2)

Basal implant Group

EXPERIMENTAL

Patients in this group will receive four basal implants placed in the atrophied edentulous mandible. Implants will be immediately loaded using a bar-retained mandibular overdenture. Clinical and radiographic evaluations will be performed to assess implant stability and peri-implant tissue health over the follow-up period.for 3,6,12months intervventions

Device: Basal Dental implant

Compressive Dental implant

EXPERIMENTAL

Patients in this group will receive four compressive implants placed in the atrophied edentulous mandible. Implants will be immediately loaded using a bar-retained mandibular overdenture. Clinical and radiographic evaluations will be performed to assess implant stability and peri-implant tissue health over the follow-up period.

Device: Compressive Dental implant

Interventions

Basal Dental implant DEVICE

Placement of four basal dental implants in the atrophied edentulous mandible followed by immediate loading using a bar-retained mandibular overdenture.

Also known as: Basal implant group, Immediate loading

Basal implant Group

Compressive Dental implant DEVICE

Placement of four compressive dental implants in the atrophied edentulous mandible followed by immediate loading using a bar-retained mandibular overdenture.

Compressive Dental implant
