In everyday dentistry, lithium disilicate is a valid option for single-fix partial dentures, and this material crystallization process is available with two protocols: long and short. This study's aim was to assess the effects of these two different crystallization protocols, long and short, on the marginal gap of lithium disilicate single crowns. A total of 24 abutment plastic teeth were scanned using an intra-oral scanner.

- The study investigated how sterilization impacts the measurements of implants in a straight line using two different scanning methods: laboratory scanners (LBS) and intra-oral scanners (IOS).
- A 3D model was used to conduct multiple scans of a titanium intra-oral scan body (ISB) both before and after sterilization, with the results analyzed for discrepancies in measurements.
- Findings revealed that sterilization significantly increased measurement errors for most implant distances and axes, highlighting the need for further research to establish guidelines on the sterilization of ISBs.
Purpose: Assess whether a Retroaortic left renal vein (RLRV) affects vertebral osteophyte formation in the lumbar spine, compared to normal anatomy left renal vein.
Methods: We conducted a retrospective case-control study. Computed tomography (CT) scans of individuals with a RLRV (study group) were compared to age- and gender-matched normal anatomy CT scans (control group).
: In everyday dentistry, monolithic single crowns can be cemented with self-adhesive resin cements. The aim of this in vitro study was to evaluate how the marginal adaptation of full monolithic zirconia-reinforced lithium silicate (ZLS) single crowns is influenced by three different self-adhesive resin cements. : Forty-five typodont teeth fully prepared for full monolithic crowns were divided into three groups (fifteen each) for the use of three different self-adhesive resin cements.
