简要总结
this research aims to compare between using multiunit abutments and OT Equator abutments for constructing implant supported fixed mandibular prosthesis regarding the marginal bone height alteration around the implants through radiographic evaluation
详细描述
Patient selection:
Fourteen completely edentulous male patients free from any systemic diseases that would affect bone metabolism, had no history of recent administration of chemotherapy or radiotherapy and no history of para-functional habits will be selected from out-patients clinic.
Grouping of patients:
The first group will include seven patients who will be planned to receive screw retained implant supported mandibular prosthesis with multiunit abutments.
The second group will include seven patients who will be planned to receive screw retained implant supported mandibular prosthesis with OT Equator abutments.

研究组 & 干预措施
multiunit abutments
multiunit abutments will be used to support the implant-supported prostheses
干预措施: different types of abutments (multiunit abutments OR OT EQUATOR abutments) will be screwed to the four implants to support the prosthesis (Other)
OT EQUATOR abutments
OT EQUATOR abutments will be used to support the implant-supported prostheses
干预措施: different types of abutments (multiunit abutments OR OT EQUATOR abutments) will be screwed to the four implants to support the prosthesis (Other)
结局指标
主要结局
crestal bone loss around implants
时间窗: 12 months
The DIGORA Optime intraoral sensor and a specially built acrylic template for each patient will be used to take intraoral radiographs with the standardized long cone paralleling technique to measure changes of crestal bone level around each implant. Periods of 0 (immediately after delivery of final prosthesis), 3, 6, and 9 months after delivery of final prosthesis for radiographic evaluation.
