Summary
Orthodontic extrusion of nonrestorable teeth before dental implant placement significantly improves bone and gum tissue at implant sites. This method offers a viable alternative for enhancing implant recipient sites.
Area of Science:
- Dental Implantology
- Orthodontics
- Periodontology
Background:
- Nonrestorable teeth often compromise implant recipient site quality.
- Alveolar bone and gingival characteristics are crucial for successful dental implant outcomes.
Purpose of the Study:
- To evaluate the effectiveness of orthodontic extrusion for improving implant site bone and gingival characteristics.
- To assess orthodontic extrusion as a method for pre-implant site development.
Main Methods:
- Systematic review of electronic databases (Medline, PubMed, EMBASE, Scopus, Web of Science, CINAHL Plus) and hand searches.
- Independent article selection and evaluation by authors, with consensus reached through discussion.
- Analysis of timing, type, and magnitude of forces used in orthodontic extrusion.
Main Results:
- Eighteen articles, primarily case reports and series, were reviewed.
- Orthodontic extrusion of periodontally compromised anterior teeth was the focus.
- All reviewed cases demonstrated significant hard and soft tissue gains, improving implant site quality.
Conclusions:
- Orthodontic extrusion is a promising alternative to conventional augmentation for implant site development.
- The available literature suggests this technique enhances alveolar bone and gingival tissue.
- Further research is needed to compare its efficacy directly with other augmentation methods.
