AI Article Synopsis
- In dental surgery, when there’s insufficient bone for grafting, bone substitutes can help with regeneration.
- A study examined five osteoconductive materials in rats, comparing those filled with substitutes to naturally healing defects.
- The results indicated that while non-demineralized bovine bone excelled in integration, not all materials provided significant healing benefits over natural healing.
Article Abstract
Background: In daily dental surgery practice, when it is not possible to obtain-enough autogenous bone graft to fill bone defects, bone substitutes can be useful for bone regeneration.
Materials And Methods: After a preliminary microscopic examination of histologic samples obtained from semithin sections of the tibias of rats showing no major differences in the results both for the single material and implant time, further studies on five different osteoconductive materials used in oral clinical practice were carried out with microradiography, SEM and X-ray microanalysis. In experimental animals (rats) bone defects 3 mm large were surgically induced in both tibias: one of the defects was filled by bone substitutes and on the other side the bone defect healed naturally.
Results And Conclusions: The findings obtained were studied in depth, and allowed to conclude that the materials tested are suitable for the purpose for which they are marketed. Non-demineralized bovine bone showed the best results with a high degree of osteointegration. However, the results also show that not all the materials tested offer healing advantages over controls.

Division of Plastic and Reconstructive Surgery, Children's National Hospital.
Facial nerve dysfunction (FND) is a well-recognized but poorly documented complication of mandibular distraction osteogenesis (MDO) for Robin sequence (RS). This study aims to document the authors' experiences with FND and identify risk factors associated with this adverse event. A retrospective review of a prospectively gathered database was performed to identify patients with RS who underwent MDO at the authors' institution from March 2016 to June 2023.
