Summary
Maxillary sinus augmentation bone grafting often results in excess or insufficient bone, rarely achieving ideal outcomes in both dimensions. Digital planning can help optimize future bone graft quantification for dental implant placement.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Biomaterials in Dentistry
Background:
- Maxillary sinus augmentation is crucial for dental implant success in the posterior maxilla.
- Predicting and achieving ideal bone graft volume is challenging.
- Digital planning offers a novel approach to assess radiographic outcomes.
Purpose of the Study:
- To evaluate radiographic outcomes of maxillary sinus augmentation bone grafting using digital implant planning.
- To assess bone graft volume (ideal, excess, insufficient) relative to planned implant position.
Main Methods:
- Retrospective analysis of 26 maxillary sinus elevation procedures.
- Digital superimposition of pre- and post-operative cone-beam computed tomography (CBCT) scans.
- Digital implant planning by a prosthodontic expert to define ideal apicocoronal (AC) and buccopalatal (BP) dimensions.
Main Results:
- 40.63% of procedures had insufficient bone graft in the AC dimension; 37.50% had excess.
- 21.88% achieved ideal bone graft in the AC dimension.
- 81.25% achieved ideal bone graft in the buccopalatal (BP) dimension, while 18.75% were insufficient.
Conclusions:
- Few maxillary sinus augmentation procedures achieve ideal bone grafting in both AC and BP dimensions based on implant planning guidelines.
- Most procedures result in excess or insufficient bone graft in at least one dimension.
- Future research should focus on quantifying optimal bone graft volumes using technology and interdisciplinary collaboration.
