摘要:
An improved inspection block for use in endodontia training in the form of a block of transparent material having a root canal emulating cavity therein extending from the top towards the block bottom, the cavity opening at the block top so that an endodontic file may be positioned in the cavity whereby a student may replicate manipulation of the file in the cavity to practice the art of cleaning and preparing a root canal, the block having at least one side wall surface configured to optically magnify the root canal.
摘要:
An improved dental post formed of a unitary, elongated metal post having a proximal portion and a distal portion, the distal portion being configured to be received in a prepared drill hole in a tooth, the proximal portion being configured to extend externally of a tooth to receive a dental device, such as a crown, thereon, the proximal portion having a porous surface to which dental device materials securely adhere, the porous surface preferably having interconnected interstices. In one embodiment the post distal portion is irregularly configured to thereby accept a crown having a highly contoured configuration.
摘要:
An improved denture having a gum simulating base with a curved recess therein configured to fit the alveolar ridge of a user with simulated teeth supported by the base, some of the teeth having exposed chewing surfaces and an elongated chew enhancing bar of thin metal positioned within adjacent teeth having chewing surfaces, the bar having a generally rectangular cross-sectional configuration with opposed first and second longitudinal edges, the bar first longitudinal edge being exposed at the chewing surfaces of at least three adjacent teeth.
摘要:
A combined storage container and installation device for a dental retentive pin. The storage container is elongated and has a top opening. A cap has a recess therein to hold the proximal end of the dental retentive pin while allowing fluid to pass into and through the recess. The cap is received and held in the open top of the container. By holding and manipulating the cap, the dental retentive pin may be removed from the container and installed under sterilized conditions without the user touching the pin.
摘要:
An attachment for removably supporting a denture in the mouth of the user in which the user has at least two spaced apart dental posts implanted therein, the attachment including a first basic portion in the form of an anchor member semi-permanently attached to the anchor post and being curved to generally the shape of the alveolar ridge of the user and having a bar portion extending between the spaced apart dental posts, the anchor member having retention recesses at each end. The attachment's second basic portion is a denture member which conforms generally to the contour of the anchor member and which is engagable in proximity with the anchor member. The denture member is cast within a denture having simulated gum portions and teeth portions. The denture member has integrally formed projections which are removably insertable into the recesses in the anchor member, the axes of the projections and the axes of the recesses being inclined toward planes of the anchor member and the denture member. The denture member includes an arm pivotal between a locked and an unlocked position. The arm has a blade portion which extends underneath the anchor member so that the arm when in the locked position retains the denture within the mouth of the user. The bar portion is generally circular in cross-section and the projections and recesses are dimensioned to permit limited pivotal movement of the denture member relative to the anchor member when the denture is locked to the anchor member.

Meat tenderization is achieved in a closed vessel in which the meat is placed, the vessel having a liquid medium therein, which may be a marinade, of a depth at least sufficient to cover the meat, and an air passageway port. A vacuum pump is connected to the port and a high vacuum is pulled on the interior of the vessel. While a high vacuum is maintained, the level of vacuum is rapidly cycled. The rapid variation of vacuum serves to tear and disrupt muscle and connective tissue in the meat and to increase absorption of the marinade.
摘要:
An electrically animated fishing lure having a lure body, a motor retained by the body, a propulsion means driven by the motor whereby when the motor is energized the lure is caused to move on or through water, the lure being arranged to travel in a non-linear path, and an electrical conductor extending with a fishing line by which electrical energy is provided to the motor. The characteristic of the lure moving in a non-linear path permits a fisherman to control the movement of the lure in and around obstructions in the water being fished. The preferred propulsion means includes the use of oppositely extending rotating wings, one of the wings being configured to provide greater propulsion than the other and in another embodiment a flow cavity is provided having jets extending to each side of the lure, one of the jets providing greater thrust than the other.
摘要:
An attachment for removably supporting a denture in the mouth of the user in which the user has at least two spaced apart dental posts implanted therein, the attachment including a first basic portion in the form of an anchor member semi-permanently attached to the anchor post and being curved to generally the shape of the alveolar ridge of the user and having a bar portion extending between the spaced apart dental posts, the anchor member having retention means at the ends thereof such as in the form of a recess at each end. The attachment second basic portion is a denture member which conforms generally to the contour of the anchor member and which is engageable in proximity with the anchor member. The denture member is cast within a denture having simulated gum portions and teeth portions. The denture member has retention means such as integrally formed posts which are removably insertable into the recess in the anchor member, the axis of the posts and the axis of the recesses being inclined toward planes of the anchor member and the denture member. The denture member includes an arm pivotal between a locked and an unlocked position. The arm has a blade portion which engages the anchor member at a point intermediate the retention means so that the arm when in the locked position retains the denture within the mouth of the user, the arm being engageable at its outer end by the fingernail of the user so that it can be pivoted to the unlocked position, allowing the denture to be removed.
