A Retrospective Cone Beam Computed Tomography Study of The Lateral Wall Bony Window

NCT06309706 | Completed

• 1 other identifier: JXHU
• Study Type: observational
• Target: 1,000
• Locations: 1 country
• Sites: 1

Brief Summary

Three experienced observers were asked to screen all the CBCT images from the Stomatology Hospital,Zhejiang University School of Medicine, between September 1, 2019 and December 31, 2019, and counted 1000 maxillary sinus CBCT images that met the criteria. Later, 1000 CBCT images were further measured and analyzed, and indicators such as maxillary sinus buccal wall thickness, morphology, whether there is blood vessel or not, whether there is bone septa or not were counted. The variation rules and related factors were summarized by SPSS analysis.

Study Population

edentulous ridges in the bilateral posterior maxillary area in Chinese patients

You may qualify if:

• Images were included if the following criteria were met: (1) patients were 18 years or older, (2) presence of teeth adjacent to or opposing the edentulous area allowing the location of the edentulous ridges corresponding to the tooth site to be identified, (3) presence of maxillary dentition defect in any tooth positon of the second premolar, the first molar or the second molar, (4) the maxillary sinus to be measured was visible from its floor to at least 15 mm high.

You may not qualify if:

• Images were excluded if any of the following criteria were met: (1) images were unclear or incomplete due to scattering or other reasons, (2) pristine maxillary posterior extraction sites after less than 3 months of healing and the tooth extraction sockets could be obviously identified, (3) the maxillary sinus had been grafted for implant-supported prosthesis, (4) implants or other prosthetic devices were present in maxillary posterior edentulous position, (5) orthodontic brackets and wires in images were present; (6) the location of the edentulous sites could not be determined, (7) sinus pathology was present that made the measurement impossible.
