For selective grinding in the patient's mouth, the anterior bite plate was worn in the moth and the patient was asked to tap and slide her anterior teeth against the plate for five minutes while in an upright position. The plate was removed, and the patient was asked to close her jaw until tooth contact was made and then hold that position.
ConspectusConventionally, the virtue of porosity is only given to porous solids. Metal Organic Frameworks (MOFs), carbon materials, or zeolites are some examples. However, processing these solids is not a straightforward task. Here, we discuss how to endow porous solids (MOFs) with liquid phase processability. More specifically, we show that surface modification of MOF …
Occlusal adjustment, also referred to as occlusal equilibration, involves selective grinding of tooth surfaces with the goal of improving tooth contact patterns. The treatment can be an adjunctive therapy used to alleviate symptoms of temporomandibular dysfunction or, more commonly, to complement comprehensive prosthodontic reconstruction.
Inconel 718 alloy was fabricated by selective laser melting (SLM) and treated with different solutions and two-stage aging heat treatments (H1-H4). The microstructure evolution of the alloy under four different heat treatments was analyzed, and the influence of the size and quantity of precipitates on the mechanical properties of the alloy under different aging …
Selective grinding in complete denture Prosthodontics is an important laboratory procedure which is carried out by remounting of the dentures after processing is completed. This remounting may either be laboratory remount or patient remount.

To obtain a final model, which included only significant explanatory variables, we sequentially dropped insignificant terms using either Kenward–Roger's F test or likelihood-ratio tests, for models of brightness and chromatic contrast, respectively. If a model term was insignificant but improved the AIC of the model, it was retained.
Fine grinding or milling reduces the particle size down to as low as 1.0 micrometer (µm) (4 x 10-5in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

Selective grinding is an operation that consists in sorting polymers after shredding. Specific particle size distributions characterize each polymer in the output stream and these differences are used to recover certain polymers by sifting. This process is based on the brittle or ductile properties of polymers.

Avoiding remounting the dentures on articulator and selective grinding leads to, 1) A deformation of underlying soft tissues, 2) Discomfort, and. 3) Destruction of the underlying supporting bone. Later occlusal errors may be concealed and impossible to locate and correct because of distorted and swollen tissues.
