Summary
Replanted teeth with titanium root screws showed successful healing, with either osseointegration or connective tissue encapsulation around the screws being acceptable outcomes. Further research is needed to determine the long-term endpoint of this healing process.
Area of Science:
- Dental research
- Oral surgery
- Biomaterials science
Background:
- Tooth avulsion and replantation present challenges for periodontal and periapical tissue healing.
- Titanium root screws offer a potential method for stabilizing replanted teeth.
Purpose of the Study:
- To evaluate the marginal and periapical healing of replanted teeth after extraoral cementing of titanium root screws.
- To assess the integration of titanium screws within the root canal and surrounding tissues.
Main Methods:
- Extraction and replantation of teeth.
- Extraoral cementing of apically exposed titanium root screws into the root canal.
- Histological evaluation of periodontal tissues and screw integration.
Main Results:
- Periodontal tissues healed successfully in 5 out of 6 replanted teeth, with normal periodontal membrane or surface resorptions.
- Osseointegration of titanium screws occurred in 3 out of 6 teeth.
- Connective tissue encapsulation formed around the screws in the remaining 3 teeth.
Conclusions:
- Both osseointegration and connective tissue encapsulation are acceptable healing outcomes for titanium root screws in replanted teeth, provided inflammation is prevented.
- Further investigation is required to determine the definitive long-term endpoint of these healing processes.
