Summary
Chin implants can cause mandibular bone resorption, a common occurrence. Further research with longer follow-up periods is recommended to fully understand this phenomenon.
Area of Science:
- Plastic Surgery
- Oral and Maxillofacial Surgery
- Biomaterials Science
Background:
- Chin augmentation using implants is a long-established procedure.
- Potential association between chin implant usage and mandibular bone resorption has been noted.
- Understanding the extent and implications of bone resorption is crucial for patient safety and procedural outcomes.
Approach:
- A systematic literature review was conducted using major scientific databases (PubMed, Web of Science, Scopus, Google Scholar).
- Search terms focused on chin augmentation, implants, resorption, and bone.
- Studies were included if they involved human subjects and reported radiographic evidence of bone resorption post-chin implantation.
Key Points:
- Twenty-eight studies met the inclusion criteria.
- No significant correlation was found between publication year and the prevalence or depth of bone resorption.
- Longer follow-up periods were associated with deeper bone resorption, though prevalence was not significantly affected.
- Most studies reported mean bone resorption of less than 2 mm with follow-up periods under 5 years.
- The most cited study received 69 citations, with limited contributions from radiology journals.
Conclusions:
- Mandibular bone resorption is a frequent consequence of various chin implant materials.
- Increased clinical recognition and dedicated research focusing on longer follow-up durations are essential.
- Further investigation is needed to fully elucidate the long-term effects and management strategies for chin implant-associated bone resorption.
