A methods and apparatus is disclosed herein that confirms the accuracy of dental casts. The device has four adjustable arms terminating in rests. The rests are slightly concave to receive methylmethacrylate. The arms are adjustable to mate rests with selected points or cusp tips on the model. In use, the set screw is loosened to allow a friction fit adjustment of the four arms. Once the four arms are adjusted so that the rests are aligned over desired cusp tips a locking screw is tightened. The arms are held immobilized. Methylmethacrylate is now added to the concave portion of rests. While this acrylic is still soft it is returned in the same location on model to register the imprint of the preselected cusp tips. The verifier can now be utilized to verify accuracy of another clone model by placing in similar manner on second cast. The verifier should come to rest on the second model exactly as it did on the original.

A system for measured tightening of an oil filter to an engine block mount includes an array of clocks placed circumferential around oil filter (20). Each clock has one dark hand (26) and one light hand (28). The light hand is advanced of the dark hand. The degree of tightening is determined by amount of separation between hands. As filter is rotated, next clock coming into view, has hands positioned one hour advanced (4-13). Panoramic movement of hands as filter is turned will indicate degree of rotation and tightening.

A dental impression technique is disclosed which actually includes the presents of air pockets within the dental impression material. The technique describes including small sponges into the tray impression material while mixing base and catalyst. Air pockets are thus created evenly within the impression material. Air pockets may also exist by mixing air into material, small premanufactured spheres, or by chemical reaction.

A new type of dental impression device is disclosed, which aides in producing more accurate impressions. The device is a spring loaded device which holds a panel flat against the teeth. This panel is custom fabricated to fit against the teeth just below the height of contour. It temporarily yields a flattened surface, masking all of the irregular surfaces beneath it. The dental impression material may then be removed without the distortion caused by the associated stretching over the curves of the teeth.

An improved dental impression tray fabricated with vertical rests that anchor onto predetermined areas of the mouth to allow stabilization of tray while impression material sets. This disclosure also provides for a venting of selected teeth to the outside air to eliminate damaging force of vacuum on freshly cured material when tray is lifted. More specifically, the practitioner fills the impression tray with moldable material and seats fully into the mouth. Venting pins are immediately fitted through impression tray and impression material and seated onto the occlusal surfaces of the teeth. After the impression material has set, venting pins are removed. The impression tray is then lifted vertically and removed.

A dental/gingival stimulating article is disclosed that provides interdental stimulation and plaque removal to several teeth at once. This design holds many stimulator tips that have broadened but narrow profile paddle ends. The instrument is held in one hand and directed with appropriate direction and force to guide fiber ends into the spaces between the gum and teeth. It will reach several papillary areas. The rotational direction used on the handle will dissipate to a massaging motion within the sulci. Therefore, the threat of interproximal caries is reduced and the occurrence of periodontal disease is minimized.
