IMMEDIATE IMPLANTS: GRAFT VS NO GRAFT

IMMEDIATE IMPLANTOLOGY: EFFECTS OF BONE GRAFTING ON MANDIBULAR BONE MICROSTRUCTURE USING FRACTAL ANALYSIS

This prospective, randomized, controlled, split-mouth clinical trial aims to evaluate the effect of bone grafting on mandibular bone microstructure following immediate implant placement using fractal analysis of panoramic radiographs. Forty systemically healthy adults requiring bilateral immediate implant placement in the mandibular anterior region will be enrolled. In each participant, one implant site will receive a bone graft (Gen-Os), while the contralateral site will serve as the non-grafted control. Panoramic radiographs obtained during routine postoperative follow-up at 1 and 3 months will be analyzed using ImageJ software to calculate fractal dimension values. The primary outcome is the comparison of fractal dimension values between grafted and non-grafted implant sites. The results are expected to provide evidence regarding the effect of bone grafting on early bone healing and microstructural changes following immediate implant placement.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: BONE GRAFT GROUP
IMMEDIATE IMPLANT SITES RECEIVING GEN-OS BONE GRAFT MATERIAL FOLLOWING TOOTH EXTRACTION. BONE HEALING WILL BE EVALUATED USING FRACTAL ANALYSIS OF ROUTINE PANORAMIC RADIOGRAPHS OBTAINED AT 1 AND 3 MONTHS.
GEN-OS BONE GRAFT MATERIAL WILL BE PLACED IN THE EXTRACTION SOCKET DURING IMMEDIATE IMPLANT PLACEMENT ACCORDING TO THE STUDY PROTOCOL. NO ADDITIONAL EXPERIMENTAL PROCEDURES WILL BE PERFORMED.
Active Comparator: NO BONE GRAFT GROUP
IMMEDIATE IMPLANT SITES WITHOUT BONE GRAFTING FOLLOWING TOOTH EXTRACTION. BONE HEALING WILL BE EVALUATED USING FRACTAL ANALYSIS OF ROUTINE PANORAMIC RADIOGRAPHS OBTAINED AT 1 AND 3 MONTHS.
Immediate implant placement without bone grafting following tooth extraction. Bone healing will be evaluated using fractal analysis of routine panoramic radiographs obtained at 1 and 3 months.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
FRACTAL DIMENSION VALUE MEASURED USING IMAGEJ SOFTWARE
Time Frame: 1 month after immediate implant placement and 3 months after immediate implant placement
Fractal dimension values of the peri-implant bone will be measured on digital panoramic radiographs using ImageJ software. Fractal dimension is a unitless numerical parameter used to assess trabecular bone microstructure. Higher values indicate greater trabecular complexity.
1 month after immediate implant placement and 3 months after immediate implant placement

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
CHANGE IN FRACTAL DIMENSION VALUE MEASURED USING IMAGEJ SOFTWARE
Time Frame: 1 month and 3 months after immediate implant placement
Fractal dimension values of the peri-implant bone will be measured on digital panoramic radiographs using ImageJ software. The change in fractal dimension values between the 1-month and 3-month assessments will be evaluated separately for grafted and non-grafted implant sites.
1 month and 3 months after immediate implant placement
