Summary
Overcoming the vertical and horizontal bone deficiency in the posterior maxillae are considered as the most challenging scenarios for implant-supported oral rehabilitation in modern implant dentistry. Therefore, a comprehensive and precise understanding of such anatomical structures are needed to avoid potential complications that ultimately might jeopardize the treatment outcome.
Cone-beam computerized tomography (CBCT) offers some advantages to conventional CT-scan such as lower-dose radiation with high isotropic spatial resolution and cost. Therefore, it offers a viable and reliable tool to study anatomical structures such as the posterior atrophic maxillae
Eligibility Criteria
- Images were included if:
- Pristine maxillary posterior atrophic ridges (between premolars and molars) as a result of missing single or multiple teeth for over than 12 months.
- Residual ridge height (RH) was < 10 mm.
- Presence of teeth adjacent to or opposing the edentulous area so the location of the edentulous ridges corresponding to the tooth site could be identified.
- The maxillary sinus to be measured was visible from its floor to at least 15 mm from the alveolar crest of the edentulous ridge.
- Images were excluded if:
- Images were unclear or incomplete due to scattering or other reasons
- Edentulous ridge height was more than 10 mm
- Ridge preservation/augmentation simultaneous/delayed to tooth extractions
- Grafted maxillary sinus for implant-supported prosthesis
- The location of the edentulous ridge cannot be determined
- Implants or other prosthetic device restoring the posterior ridge
- Presence of sinus pathology that made the measurement impossible
- The outline of the edentulous ridge cannot be identified due to low 'grey scale' density
