Assessment of Deproteinized Bovine Bone for Immediate Implants Placement in Maxillary Esthetic Zone: A Randomized Clinical Study

: Many of studies have been performed to improve osseointegration and bone density around implants by modifying the implant by adding bone graft or substitute material that increase success of implant. Aim: The aim of this study is to evaluate clinically the efficacy of deproteinized bovine bone in maxillary Esthetic zone to promote bone formation and improve outcomes in immediate implant cases. Methodology: 16 immediate implants will be placed in maxillary esthetic zone. That study will be Conducted on 16 hopeless teeth divided equally and randomly into two groups Randomization will be done using www.randomizer.org ., Group 1: 8 hopeless teeth will be replaced by immediate dental implants represent the (control group) where the implants will be placed without bone graft, Group 2: 8 hopeless teeth will be replaced by immediate dental implants represent the (study group) where the implants will be placed with deproteinized bovine bone graft. The implant stability will be assessed clinically using (Ostell) immediate postoperative and after 6 months and Postoperative pain using visual analogue scale (VAS)

Pre and Post Operative CBCT Will be taken. Bone density will be assessed Using 3D onDemand Softwear.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Implant Stability (ISQ)
Time Frame: Baseline (immediately after implant placement) and 6 months postoperatively
Clinical stability of dental implants was assessed using the Osstell device. The implant stability quotient (ISQ) was measured immediately after implant placement and at 6 months postoperatively. ISQ scores range from 1-100, with scores ≥70 indicating high stability, 60-69 medium stability, and <60 low stability.
Baseline (immediately after implant placement) and 6 months postoperatively
Postoperative Pain (Visual Analog Scale, VAS)
Time Frame: 1, 3, and 7 days postoperatively
Patients reported the degree of pain using a 10-cm visual analog scale (VAS), where 0 = no pain and 10 = worst possible pain. Pain was assessed at 1, 3, and 7 days postoperatively.
1, 3, and 7 days postoperatively
Visual Scale of Edema
Time Frame: 1, 3, and 7 days postoperatively
Facial edema was assessed using a visual grading scale: No edema, Low-grade, Intermediate-grade, and High-grade, based on visual inspection and palpation. Edema was evaluated at 1, 3, and 7 days postoperatively.
1, 3, and 7 days postoperatively
Peri-implant Bone Density
Time Frame: Baseline (immediately after implant placement) and 6 months postoperatively
Bone density around the implants was measured using CBCT radiographs and analyzed with 3D OnDemand software. Measurements were recorded immediately postoperatively and at 6 months.
Baseline (immediately after implant placement) and 6 months postoperatively
