A comparative study for the long-term stability of simultaneously placed dental implants with autologous bone graft harvested from iliac crest and maxillomandibular bone

Object. Autologous bone graft harvesting from the iliac crest remains the gold standard for fusion surgery. One disadvantage of autologous bone harvesting is the patient's enduring postoperative pain at the donor site. Nerve injury is one of the postulated mechanisms that may account for this pain. The object of this study was to determine whether the lateral cutaneous branch of the subcostal nerve is vulnerable to injury in the process of obtaining grafts from the anterior iliac crest. Methods. Anatomical dissections were performed on 10 cadaveric specimens to ascertain the size of the T-12 subcostal nerve and its position in relation to the iliac crest. Conclusions. The lateral cutaneous branch of the subcostal nerve may lie as close as 6 cm from the anterior superior iliac spine. This nerve is very vulnerable to injury when harvesting bone from the anterior iliac crest. Knowledge of the anatomy may decrease the risk of injury to this nerve.

Autologous Bone

Background: Numerous operative procedures around the foot and ankle use bone graft to augment healing. Autologous bone graft remains the preferred type for these procedures. This can be harvested from the iliac crest, but complications are frequent. The purpose of our study was to investigate the option of harvesting the bone graft from the ipsilateral distal tibia or calcaneus. Method: Bone graft was harvested in 114 patients from the distal tibia (70 patients) or calcaneus (44 patients). The patients were followed postoperatively for an average of 16 (range 5 to 28) months and were evaluated for complications (minor and major), satisfaction, and healing rates. Results: There were no major complications. Ten patients (8.7%) had minor complications including initial incisional sensitivity or local numbness, none of which affected function or required additional treatment. Satisfaction rate for the procedure was 100%. Conclusion: Use of autologous bone graft harvested from the ipsilateral distal tibia or calcaneus is a safe and reliable alternative to iliac crest bone graft harvest for operative procedures of the foot and ankle.

Clinical Scenarios

Short dental implants are commonly recommended to be implemented with small crown-to-implant (C/I) ratios due to their mechanical stability — decreasing C/I ratios cause less deformation in skeletal tissue under occlusal force. However, the long-term stability of short implants with high C/I ratios remains a controversial issue due to biomechanical complications. This study evaluates the strain distribution and functional implications in an implant-supported crown with various C/I ratios using a high-fidelity, nonlinear finite-element model. Several clinical scenarios are simulated by loading implants with various implant lengths (IL) and crown heights (CH). Strain distribution and maximum equivalent strain are analyzed to evaluate the effects and significance of CH, IL, and the C/I ratio. The study shows underloading for certain implant configurations with high C/I ratio. Increasing IL and decreasing C/I in moderation demonstrates a positive effect in long-term stability.
