This study aims to compare the efficacy of two bone augmentation techniques in the posterior mandible. Twenty participants will undergo 40 surgical procedures at Espíritu Santo University (UEES) in Samborondon, Ecuador. Each patient will receive two types of bone grafts: one side will use autogenous cortical bone plates with a 50/50 mixture of autogenous bone and biomaterial (as described by Dr. Fouad Khoury), while the other side will use xenogenous cortical bone plates with the same mixture.

A thick block from the ramus area of the mandible are cut longitudinally with a microsaw into two thin pieces with the same surface area. The two thin block are used to rebuild the two wall of the future alveolar crest and stabilized with osteosynthesis screw of the edentulous area. The remaining space is filled with a mixture of autogenic and xenogeneic particulate bone.
A tridimensional Onlay xenogeneic bone graft is positioned and stabilized with osteosynthesis screw of the edentulous area. The remaining space is filled with a mixture of autogenic and xenogeneic particulate bone.
To evaluate bone formation Across Different Graft Techniques
This study aims to evaluate bone formation resulting from various bone grafting techniques, with a focus on quantifying the amount of newly formed bone.
Time frame: The evaluation will occur from enrollment through the end of treatment at 12 months. Assessments will be conducted preoperatively, 7 days post-surgery, as well as at 3, 6, and 12 months following the surgery.
To evaluate the surgery duration of across different bone grafting techniques.
This study aims to evaluate the surgery duration.
Time frame: To record the duration of surgery for both techniques, from the administration of anesthesia to the final suture
To evaluate bone quality across different bone grafting techniques.
This will involve analyzing the bone density through radiographic imaging.
Time frame: From enrollment, to the end of treatment at 12 months; evaluating at 3 days, 30 days, 3 months, 6 months and 12 months
To evaluate postoperative inflammation across different bone grafting techniques.
This study aims to evaluate postoperative inflammation following surgery. A measurement will be taken from the corner of the lip to the ear lobe using a flexible measuring tape in order to monitor the swelling. The data will be recorded in millimeters.
Time frame: The evaluation will occur prior to surgery, immediately postoperatively, on the 3rd day, 7th day, and at 14 days
