[Evaluation of peri-implant augmentation with collected bone]

Area of Science:

• Oral surgery
• Dental implantology
• Bone regeneration

Background:

• Dental implant procedures often require bone grafting for augmentation.
• Autogenous bone is a preferred graft material, but harvesting can be invasive.
• Bone collectors offer a minimally invasive method for collecting bone during osteotomy.

Purpose of the Study:

• To quantify bone harvested using the Aspeo 12000 bone collector during dental implant osteotomies.
• To characterize the histological properties of the collected bone debris.
• To evaluate the clinical efficacy of using collected bone for peri-implant augmentation.

Main Methods:

• 18 bone samples were collected from patients undergoing dental implant installation using the Aspeo 12000 bone collector.
• Statistical analysis (ANOVA) assessed differences in bone yield based on patient demographics and anatomical location.
• Histomorphometric analysis using hematoxylin and eosin staining evaluated bone proportion and viability.

Main Results:

• Approximately 93% of 'wet' bone volume was obtained per osteotomy, with no significant differences based on sex or anatomical location.
• Histological analysis revealed a mean bone proportion of 94.2% in the collected samples, alongside coagulum.
• Peri-implant defects augmented with collected bone showed successful augmentation and evidence of bone growth within 3-6 months.

Conclusions:

• Bone collectors are effective for harvesting bone during dental implant surgery.
• Collected bone is a viable autograft material for augmenting small peri-implant defects.
• This technique facilitates bone regeneration and simplifies augmentation procedures.
