Precision of stereophotogrammetry in complete arch implant recordings: A clinical study.
J Prosthet Dent
January 2025
Assistant Professor, Department of Pre-Clinic Dentistry, Faculty of Biomedical and Health Sciences, European University of Madrid, Madrid, Spain. Electronic address:
Statement Of Problem: Stereophotogrammetry has been proposed as an alternative to intraoral scanners for recording the location of multiple dental implants. Most studies evaluating its accuracy have been in vitro, and clinical studies are lacking.
Purpose: The purpose of this clinical study was to evaluate the precision of a stereophotogrammetry system for complete arch prostheses supported by 6 implants.

Objective: To quantitatively evaluate the accuracy of data obtained from liquid-interference surfaces using an intraoral 3D scanner (IOS) integrated with a compressed airflow system, so as to provide clinical proof of accuracy for the application of the compressed airflow system-based scanning head in improving data quality on liquid-interference surfaces.
Methods: The study selected a standard model as the scanning object, adhering to the "YY/T 1818-2022 Dental Science Intraoral Digital Impression Scanner" guidelines, a standard that defined parameters for intraoral scanning. To establish a baseline for accuracy, the ATOS Q 12M scanner, known for its high precision, was used to generate true reference values.

Fourth Clinical Division, Peking University School and Hospital of Stomatology & National Center of Stomatology & National Clinical Research Center for Oral Diseases & National Engineering Research Center of Oral Biomaterials and Digital Medical Devices & Beijing Key Laboratory of Digital Stomatology, Beijing 100081, China.
Objective: To compare the influence of different emergence profile of implants in mandibular molar on the peri-implant soft tissue.
Methods: Forty-four implants were divided into two equal groups by mucosal thickness, ≥2 mm (group A) or < 2 mm (group B), and were randomly included in the test group and the control group. In the control group, the patients were treated by a prosthesis with no transmucosal modifications (subgroups A1 and B1).

Objective: To evaluate the clinical efficacy of clear aligner therapy in patients with severe periodontitis accompanied by pathological tooth displacement in the anterior region.
Methods: This retrospective study analyzed patients diagnosed with severe periodontitis and pathological displacement in the anterior region, who visited both the Periodontics and Orthodontics Departments at Peking University School and Hospital of Stomatology between 2019 and 2022. A total of 26 eligible cases were included in this study.
