Autogenous teeth used for bone grafting: A systematic review

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Autogenous tooth bone graft materials are emerging for dental applications.
• Previous studies suggest positive clinical and histological outcomes.
• Alveolar ridge augmentation is a common dental procedure.

Purpose of the Study:

• To systematically review the reliability of autogenous tooth bone graft material for alveolar ridge augmentation.
• To evaluate clinical and histological outcomes of using teeth as bone graft material.
• To determine if autogenous teeth are a viable bone graft option for alveolar ridge deficiency.

Main Methods:

• Systematic literature review of articles published between 2007 and 2017.
• Analysis of four outcome variables: implant stability, post-operative complications, implant survival/failure rates, and histological analysis.
• PICO model used to frame the research question regarding autogenous teeth as bone grafts.

Main Results:

• Mean implant stability: primary 67.3 ISQ, secondary 75.5 ISQ.
• Wound dehiscence was the most frequent complication (29.1%).
• Implant survival rate was 97.7% with a 2.3% failure rate; histological analysis indicated bone formation.

Conclusions:

• Autogenous tooth bone grafting appears clinically safe with good bone-forming capacity.
• Positive results regarding implant stability were observed.
• Insufficient evidence exists to draw definitive conclusions on the long-term effects.
