简要总结
This clinical trial evaluated horizontal ridge augmentation in the posterior mandible using subperiosteal tunneling with enriched bovine bone graft matrix (sticky bone). The minimally invasive procedure addressed horizontal bone deficiencies without flap elevation, while preserving periosteal integrity and reducing patient morbidity. Ten patients underwent clinical assessment of wound healing, pain, and neurosensory changes over 4 weeks; radiological evaluation of CBCT-measured bone width at immediate postoperative and 6-month follow-up; and histological analysis of bone core biopsies obtained at implant placement to evaluate remodeling and graft integration.
详细描述
The alveolar bone is a tooth-dependent tissue that extends from the basal bone of the maxilla and mandible to form and support the tooth sockets. Resorption of alveolar bone may be attributed to a variety of factors, such as tooth loss, trauma, periodontal disease, and pathologies. Tooth loss is often followed by a bone remodeling process leading to gradual horizontal and vertical bone ridge reduction.
The posterior mandible is the most challenging region for reconstruction and implant placement due to its critical neurovascular structures, thick cortical bone, and reduced vascular trabecular bone, requiring careful treatment planning for successful outcomes Multiple techniques such as osteoplasty, narrow implants, bone augmentation, ridge splitting, and distraction osteogenesis address deficient ridge width. However, conventional augmentation in the posterior mandible requires flap elevation and barrier membranes, increasing risks of complications such as pain, swelling, wound dehiscence, and membrane exposure.
To address these limitations, this study employed the subperiosteal tunneling technique for horizontal augmentation of posterior edentulous ridges. By creating a subperiosteal pouch without extensive flap elevation, this approach reduces tissue trauma, preserves periosteal integrity essential for bone regeneration, and eliminates the need for barrier membranes by harnessing the periosteum's regenerative potential.
Bovine sticky bone was utilized for its cohesive properties, enhanced stability, and regenerative potential. (31) This study evaluated the radiological and histological outcomes of horizontal mandibular ridge augmentation through subperiosteal tunneling using enriched bovine bone graft matrix (sticky bone). Conducted at the outpatient clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Tanta University.
Ten adult patients with mandibular horizontal alveolar ridge atrophy were included in the study. Their ages ranged from 34 to 42 years (mean ± SD: 38 ± 2.6). The gender distribution was 40% male and 60% female participants, reflecting women's predominance in dental treatment-seeking behavior.
