Coralline hydroxyapatite (CHA) shows excellent clinical results for maxillary sinus augmentation, achieving successful osseointegration and ideal bone regeneration. This bone graft material offers a reliable solution for insufficient bone volume in the sinus region.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Biomaterials Science
Background:
- Maxillary sinus augmentation is crucial for dental implant success in atrophic jaws.
- Coralline hydroxyapatite (CHA) is a potential biomaterial for bone regeneration.
Purpose of the Study:
- To retrospectively evaluate the clinical efficacy of coralline hydroxyapatite (CHA) in maxillary sinus augmentation.
- To assess osseointegration and new bone formation following CHA grafting.
Main Methods:
- Retrospective analysis of 118 cases undergoing sinus lift with CHA.
- Inclusion of simultaneous (78 patients) and delayed (40 cases) implantations.
- Clinical, radiographic, histological, and histomorphometrical evaluation of outcomes.
Main Results:
- High success rates for simultaneous implants (174/174) and delayed implants (79/82).
- Histology confirmed active bone remodeling and significant new bone formation at 6 months.
- Radiology showed gradual CHA resorption over 5 years.
Conclusions:
- Coralline hydroxyapatite (CHA) is an effective bone graft material for maxillary sinus augmentation.
- CHA demonstrates favorable histocompatibility and reliable clinical outcomes.
- Single-application CHA achieves desired clinical effects and ideal osseointegration.
