Abstract: A ball head multi-unit abutment assembly is provided for use with a dental implant. The assembly includes a base having an implant bore oriented on-axis with the implant, a coping bore, and a faceted exterior at the bottom of the base configured to seat on the implant. The base also includes a ball head at the top of the base opposite the faceted exterior. The ball head is oriented on-axis with the coping bore. The assembly also has a coping with a stem portion and a seat portion. The seat portion has a ball head receptacle corresponding to the ball head, the stem portion having a coping screw bore, and the base is configured such that when the concave profile is seated on the ball head, the coping screw bore is brought into registration with the coping bore.

Abstract: A dental implant and post apparatus having a reverse threaded dental implant is used for mounting on a dental drill having a direction of rotation opposite the advancing direction of the helical threads of the dental implant, for installation in patient bone. The apparatus includes a dental implant having a head portion with a bore and a threaded portion, and a post (also known as an abutment) having a post stem, a lower conical portion, and an upper conical portion. The bore includes a post stem receiving portion for receiving the post stem, and a conical sidewall configured to engage the lower conical portion. The threaded portion comprises threads oriented in a direction opposite the direction of rotation of the dental drill to drive the implant in an unscrewing rotation when spun by the dental drill, thereby causing the threads to force the bone down, out, and away from the implant as it is inserted into the patient.

A first extension extends from the first jaw, the first extension having an engaging portion configured to engage the driving socket. A second extension and a third extension, both extending from the second jaw in a parallel co-terminus configuration. The second extension and the third extension are configured to grip the implant with the engaging portion in the driving socket when the first handle portion and the second handle portion are moved proximally.

Abstract: A dental implant retaining driver apparatus has a body portion and an extension portion extending from the body portion. The extension portion terminating opposite the body portion in a connection region configured to engage a dental implant in a non-rotational relationship. The body portion and the extension portion together have a bore, and a retaining rod in the bore is configured to rotate relative to the body portion and the extension portion. An engagement portion on the retaining rod extends out of the extension portion. The engagement portion is configured to engage the dental implant, such that when the engagement portion and the connection region engage the dental implant, the dental implant cannot be rotated or removed from the apparatus.

Abstract: A dental implant screw for engaging a tightening apparatus and a dental implant. The dental implant screw extends through a dental tibase and a dental prosthetic. The dental implant screw includes a shaft portion and a head portion, with the shaft portion comprising a shaft having threads disposed at least partially along the length of the shaft and the threads configured to engage the dental implant. The head portion includes a top, a sidewall, and a bottom terminating in the shaft portion. The top includes a bore for receiving the tightening apparatus. The sidewall is conical, having its largest circumference proximal the top, and its smallest circumference proximal the bottom. The sidewall makes complete contact with the tibase when fully inserted into the dental implant.

Abstract: A cortical drill for hydrating and drilling cancellous bone when preparing a dental implant includes a stem portion and a drill portion, the stem portion with a locking notch and a water inlet configured for receiving fluid under pressure into the cortical drill. The drill portion has an elongated substantially conical body having an outer wall. The drill portion has a slot portion, and the slot portion includes a cut-out forming an inlet along a peripheral surface of the conical body. A plurality of jets are formed in the slot portion, with the jets in communication with the water inlet, and the jets arranged along the slot portion, such that fluid travelling under pressure into the water inlet, travels through the stem portion and the drill portion, and exits the jets in the slot portion.

Abstract: An angled zygomatic implant apparatus for spanning a patient's zygomatic bone and maxillary bone includes a zygomatic abutment screw with a conical receptacle and san implant threaded bore, the zygomatic abutment screw is adapted for fixation in the patient's zygomatic bone, and an angled extension having an implant end adapted with a conical portion adapted for fixation to the conical receptacle of the zygomatic abutment screw. The angled extension is elongated and otherwise adapted to span the space between a patient's zygomatic bone and maxillary bone for fixing a maxillary tooth implant.

Abstract: An apparatus for guiding a zygomatic implant dental drill installed in a dental handpiece includes a collar configured to seat on a neck portion of the dental handpiece, with an offset post extending from the collar. A first extension extends from the offset post parallel to the neck portion, and a second extension extends from the first extension. The second extension is oriented parallel to the zygomatic implant dental drill, extending from the first extension to be co-terminal and off-set from the zygomatic implant dental drill. By observing the travel of the second extension along a patient's face, a dental surgeon can guide the zygomatic implant dental drill inside the patient toward the patient's zygomatic bone.

Abstract: A dental oral appliance for use with patients who suffer with sleep disorders, to reduce or eliminate snoring or obstructive sleep apnea and to open the airway for a sleeping patient. Retention for the appliance is provided by an occlusal coverge, or wire clasps, on the upper or lower teeth. A raised incisor ramp that extends from the incisal tip (biting edge) of the incisors toward the lingual, or posterior ramps, separate the upper and lower teeth to open the airway. A transpalatal bar or translingual bar, which extends from the inside (lingual) of the right molars to the inside of the left molars, inhibits the upward and backward movement of the tongue. A posterior tongue restrainer has two parts, the first part being embedded in the transpalatal bar and the second part removably attachable to the first part, in order to further inhibit the upward and backward movement of the tongue.

Abstract: System, method and framework for generating scenarios used in risk management applications. The present invention is based on a generic framework that provides levels of abstraction, segregates risk factors and models, and structures a scenario generation process.

Abstract: A dental implant system and method for inserting a threaded implant in both edentulous and partially edentulous space of a patient's jaw bone in the form of a threaded implant having at least one hole adapted along its longitudinal axis for insertion of an abutment post and a drilling gauge having leg portions adapted for use with the implant. Any one of the leg portions includes a hole equally aligned with thee hole of the threaded implant when placed proximate the gauge. The implant is inserted into the hole drilled in the jaw bone. The hole of the drilling guage marks the location where a hole will be drilled vertically into the jaw bone through which an abutment post would be inserted and screwed into the hole of the implant, for subsequent placement of a prosthetic tooth.

Abstract: The present invention relates generally to a system of components, comprising an integrated architecture, which supports calibration of financial models, and the structuring, pricing, mark-to-market valuation, simulation, risk management, and reporting of a variety of credit instruments subject to both credit and market risk (e.g., interest rate, foreign exchange risk). Detailed instrument complexities may be accommodated, by modeling the underlying economic behavior driving the exercise of embedded options and other structural features of credit instruments by implementing detailed economic behavioral models.
