Objective: To analyze the clinical application and limiting factors of the Hall technique (HT) preformed metal crowns in caries of primary molars and to provide reference for its clinical application based on a questionnaire survey.
Materials And Methods: From June to December 2022, a questionnaire was distributed to pediatric dentists through the WeChat platform using "Questionnaire Star" to analyze the clinical application and influencing factors of the HT preformed metal crowns in caries of primary molars.
Results: A total of 700 survey questionnaires were distributed, and 650 valid questionnaires were recovered, with a effectiveness rate of 92.

Purpose: The purpose of the study was to investigate the accuracy of complete-arch intraoral scans for all-on-4 implant treatment under simulated intraoral variables.
Materials And Methods: A maxillary model designed to receive 4 implants in the regions of first molars and canines was used. Intraoral digital scans were completed in a simulation device by simulating two2 different clinical conditions: normal intraoral variables (NIV) and limited intraoral variables (LIV).

Objectives: The aim of the present study was to compare the accuracy of fully guided implant insertion in vitro achieved by two fabrication methods in a cohort of undergraduates. We hypothesized that both methods achieve a comparable accuracy.
Methods: Surface scans and cone beam computed tomography images of 48 mandibular models were matched.

Objectives: This study investigated the effects of thread design on the soft and hard tissues around implants in rat maxillary peri-implantitis-like lesions.
Methods: Fourteen, 9-week-old, female Wistar rats were used in this study. Two types of grade IV titanium tissue-level implants with a standard V-shape and buttress threads were prepared (control and test implants, respectively).

To assess the biomechanical behaviors of endodontically treated molars (ETMs) restored with endocrowns composed of different materials, forty mandibular molars were assigned to five groups (n = 8 each). Untreated molars constituted the control group (group C); the rest of the teeth that underwent root canal therapy were restored with endocrowns composed of polycrystalline ceramics (ST zirconia, UPCERA) in group ZR, lithium disilicate glass ceramics (UP.CAD, UPCERA) in group LD, resin-based nanoceramics (Hyramic, UPCERA) in group NC, and feldspathic ceramics (CEREC Blocs, Sirona) in group FC.
