Basal Versus Compressive Implant Designs Immediately Loaded With Bar Retained Complete Overdenture for Atrophied Edentulous Mandibular Ridge: Clinical and Radiographic Study of peri_implant Tissue Health

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

Detailed Description

Patients will be divided randomly in to 2 equal groups:

  • Group1: this group will receive immediate loaded screw retained complete overdenture supported by 4 basal implants design .
  • Group2 :this group will receive immediate loaded screw retained complete overdenture supported by 4 compressive implants design
  • After final implant placements, they will be immediately scanned by intraoral scanner to construct milled in titanium bar which will be immediately screwed into the implants
  • Mandibular screw retained complete overdenture will be constructed.

Evaluation will be for:

  • Peri implant tissue health that will be measured according to mombelli(12) at the time of insertion(T0), 6months(T1) and 12months (T2).
  • Marginal bone height changes will be measured using standardized digital panoramic x-ray(13) after 6months (T0), 12month(T1) and 24months(T2) after prosthesis insertion.
  • Periotest will evaluate the stability of the implants during implantation (T0) , 3months(T1) and 6months(T3) following surgery(14) .

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Basal implant Group
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
Placement of four basal dental implants in the atrophied edentulous mandible followed by immediate loading using a bar-retained mandibular overdenture.
Other Names:
  • Basal implant group
  • Immediate loading
Experimental: Compressive Dental implant
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
Placement of four compressive dental implants in the atrophied edentulous mandible followed by immediate loading using a bar-retained mandibular overdenture.
