With the steadily growing frequency of AIDS, many dental researchers and clinicians have become more interested in disinfection and sterilization procedures. Impressions made in the clinic are potential contamination pathways. All patients may be considered as potentially infectious and the impressions must be treated the same as those made on so-called high-risk patients. Zinc oxide-eugenol, polysulfide and silicone rubber, and probably polyether materials are compatible with effective disinfectant solutions. The solutions do not substantially diminish the dimensional stability and the sharpness of surface detail reproduction of these impression materials. Impression compound as well as reversible and irreversible hydrocolloid, however, are not compatible with effective disinfectant solutions.

Window Technique for the Final Impression of a Maxillary Flabby Ridge: A Case Report of an Edentulous Patient.

Dentistry, King Saud University, Riyadh, SAU.
The window technique is a highly useful clinical procedure for resolving several issues while taking a final impression of a patient with a mobile or displaceable anterior maxillary ridge, also referred to as a flabby ridge. This kind of ridge is particularly problematic due to the underlying tissues lacking strength and resilience, making it challenging to achieve a solid and comfortable denture fit. This typically exacerbates the problem, as conventional pressure during impression-making induces further displacement, which reduces the impression's precision.

Aim: The aim of the present study was to comparatively evaluate the retention of complete dentures and oral health-related quality of life (OHRQoL) of patients with conventional and bioelectric impressions or transcutaneous electric nerve stimulation (TENS).
Materials And Methods: A total of thirty (n = 30) completely edentulous patients were randomly distributed into two groups: Group-C (n = 15) (Conventional) and Group-T (n = 15) (bioelectric). In Group C, border molding was performed using the manual manipulation of borders, and the final impression was made using zinc-oxide eugenol.

Background/purpose: Spacing between teeth is a common trait across different stages of dentition. With the tide of the digital impression, the scanning trueness of the intraoral scanner (IOS) is a hot subject. This study aimed to determine the correlation between the level of the spaced dentition and trueness of the intraoral scanning.

Background/purpose: The accuracy of intraoral scanners (IOSs) plays a crucial role in the success of final restorations in digital workflows. Previous studies have shown that numerous factors affect the accuracy of IOSs. Most studies have evaluated the accuracy of IOS under one restoration condition.

BACKGROUND A tooth preparation's clinical requirements and geometric configurations should take precedence over material characteristics when advocating for putty reline impression techniques for permanent restorations, since they require a technically sensitive spacer for light body elastomer. We evaluated the linear dimensional accuracy of vinyl polysiloxane-based putty reline impressions with different spacer acquisition techniques in short-span and long-span fixed partial dentures (FPD). MATERIAL AND METHODS A typodont tooth set simulated a 3-unit (short-span) and a 5-unit (long-span) FPD.
