“…Although various bone substitutes have been developed through tissue engineering, the gold standard for bone grafting remains autogenous bone, which has excellent biocompatibility, osteoconductivity, and osteoinductivity and contains living osteoblasts 1 . Autogenous bone grafts can provide support and stability to dental implants 2 , 3 and maintain proper volume combined with the surrounding bone based on its osteoinductivity, and this supports timely bone regeneration 4 .…”

“…Nevertheless, surgeons may hesitate to perform ramus harvesting due to possible donor site complications such as morbidity, sensory disturbance, bleeding, and hematoma 9 , 10 . In a recent report of 216 patients who underwent ramus harvesting, 15.3% suffered from inferior alveolar nerve (IAN) disturbance immediately after the surgery 3 . Most of these complications occur during harvest through invasion of bone marrow with neurovascular complexes.…”

Autogenous bone grafts from the mandibular ramus are a known source of inadequate bone volume scenarios of the residual alveolar ridge. However, the conventional block-type harvesting technique cannot prevent bone marrow invasion, which can cause postoperative complications such as pain, swelling, and inferior alveolar nerve injury. This study aims to suggest a complication-free harvesting technique and present the results of bone grafting and donor sites. One patient received two dental implants with a complication-free harvesting technique that involves creation of ditching holes with a 1 mm round bur. Sagittal, coronal, and axial osteotomies produced grid-type cortical squares using a micro-saw and a round bur to confirm the cortical thickness. The grid-type cortical bone was harvested from the occlusal aspect, and the harvesting was extended through an additional osteotomy on the exposed and remaining cortical bone to prevent bone marrow invasion. The patient did not suffer postoperative severe pain, swelling, or numbness. After 15 months, the harvested site exhibited new cortical bone lining, and the grafted area had healed to a cortico-cancellous complex with functional loading of the implants. Our technique, grid-type cortical bone harvesting without bone marrow invasion, allowed application of autogenous bone without bone marrow invasion to achieve acceptable bone healing of the dental implants and to regenerate the harvested cortical bone.

“…Despite its resorption tendency and propensity for donor site morbidity, autogenous bone is the gold standard for bone graft surgeries for its osteoconduction, osteoinduction, and osteogenesis properties [ 11 ]. Tooth-derived bone matrix, DDM, has recently been shown to possess osteoinductivity and an efficacy comparable to that of autogenous bone [ 12 , 13 ].…”

The purpose of this retrospective study was to evaluate bone healing after autogenous demineralized dentin matrix (DDM) grafts, focusing on the distal root of the mandibular second molar after the extraction of the third. We included retrospective data from 20 patients who had undergone molar extractions (15 male, 41.9 ± 12.0 years) between January 2020 and September 2022 and had DDM grafts implanted on the extraction socket, immediately (“immediate graft”) or 6 weeks (“delayed graft”) after the first surgery without primary closure. Patients who underwent grafting on only one side were used as the control group (n = 4). Bone defects at the mandibular second molar were measured preoperatively and 4 months after the graft surgery using cone-beam computed tomography (CBCT). Improvement of bone defect (i.e., the change in the bony defect pre- vs. postoperatively) was compared between the control and graft groups using the Wilcoxon Signed Rank test, and the difference between immediate and delayed grafts was analyzed with the Mann-Whitney U test. Complications such as infections or graft failure did not occur. Although pre-operative defects were smaller in the control than in the graft group (2.98 ± 1.77 and 10.02 ± 3.22 mm, p = 0.001), post-operative defects were similar in both (2.12 ± 0.59 and 2.29 ± 1.67 mm, respectively). The improvement ratio was not statistically significant in the control group (22.68 ± 15.36%) but a difference was observed in the graft group (76.70 ± 15.36%, p = 0.001). The amount of improvement of bone defect was not affected by graft timing or patient sex. In conclusion, DDM can improve bone defect at the distal aspect of the mandibular second molar after third molar extraction.

“…Calcium phosphate is a mineral constituent of natural bone. In addition, hydroxyapatite (HAp), tricalcium phosphate (α/β-TCP), and biphasic calcium phosphate (BCP) have been used to create a porous scaffold that serves as an artificial bone-healing aid in orthopedics and dentistry, where early cellular regeneration of the defect site and mechanical stability of the implant are considered vital issues [14,15]. Some site-specific, application-specific, and performance-specific prerequisites for using a bone substitute material in hard tissue treatment exist [16][17][18].…”

In orthopedics, a number of synthetic bone substitutes are being used for the repair and regeneration of damaged or diseased bone. The nature of the bone substitutes determines the clinical outcome and its application for a range of orthopedic clinical conditions. In this study, we aimed to demonstrate the possible applications of multichannel granular bone substitutes in different types of orthopedic clinical conditions, including bone tumor, fracture, and bone defect with arthroplasty. A clinical investigation on a single patient for every specific type of disease was performed, and patient outcome was evaluated by physical and radiographic observation. Brief physical characterization of the granular bone substitute and in vivo animal model investigation were presented for a comprehensive understanding of the physical characteristics of the granules and of the performance of the bone substitute in a physiological environment, respectively. In all cases, the bone substitute stabilized the bone defect without any complications, and the defect regenerated slowly during the postoperative period. Gradual filling of the defect with the newly regenerated bone was confirmed by radiographic findings, and no adverse effects, such as osteolysis, graft dispersion, and non-union, were observed. Homogeneous bone formation was observed throughout the defect area, showing a three-dimensional bone regeneration. High-strength multichannel granules could be employed as versatile bone substitutes for the treatment of a wide range of orthopedic conditions.
