  • Patent number: 8177554
    Abstract: A pulp chamber locator assists a dentist in performing a root canal procedure. The device includes a generally circular plate and a plurality of struts extending from the plate. The plate has a hole in the vicinity of its center. The device is inserted over a tooth, such that the struts engage the cemento-enamel junction of the tooth. The hole then indicates the proper point of entry for a dental instrument. The device may also include a rotatable indicator for showing the proper angle of entry, to insure that the instrument reaches the pulp chamber of the tooth. The dentist adjusts the position of the indicator, based on information provided by an X-ray or equivalent, and positions the dental instrument so as to be generally parallel with the indicator.

  • Publication number: 20120100500
    Abstract: This invention introduces an oral-dental anatomy modeling method and an implant treatment planning system based on a full anatomy model (FAM). Dental Implant Treatment Planning systems place implants on 2D slices of DICOM files, and sometimes on 3D models of bones and remaining teeth. Because the final look and feel of implants and restorations depend on how well they go along with the remaining teeth and soft tissues, treatment planning without tissue model presents safety and aesthetics risks. A FAM consists of models for bones, teeth, soft tissues and nerves. They are created from CT and optical scans, and assembled together with model registration techniques. The tissue model is the real differentiator. A treatment planning system uses FAM as a unique reference throughout the workflow. Its implant placement, restoration preview and surgical guide design are all based on FAM.

  • Publication number: 20120046914
    Abstract: A hybrid method for dental implant treatment planning and a corresponding approach to make a surgical guide. After digital treatment planning is performed with CT scan data, a master model is created, which embodies the patient anatomy and entire treatment plan. Jaw bone, tooth surfaces, soft tissues and nerves are all contained by the master model. The plan details including implant sizes and positions, surgical guide drill options, as well as the choice of a surgical kit, are all conveyed by the master model. Meanwhile, models of specially designed “implant inserts (or replicas)” are also generated, which have one end that fits into the implant holes on the master model and another end to make the surgical guide. The master model and inserts are manufactured with rapid prototyping technology. A surgical guide is later on made from them with conventional lab processes. A main characteristic of this approach is that the master model and the inserts are the physical embodiment of a virtual treatment plan.

    Abstract: Root apex position model data associated with electrical characteristic values between a measurement electrode and a mouth electrode in a state in which the distal end of the measurement electrode is located at a root apex position of a root canal is stored in a storage unit. A power supply applies measurement signals of 500 Hz and 2 kHz between the measurement electrode and the mouth electrode. Two different current values flowing between the measurement electrode and the mouth electrode are detected. These current values are compared with the root apex position mode data stored in the storage unit. If the root apex position data includes any data which coincides with the current values, it is detected that the distal end of the measurement electrode is located at the root apex position.

  • Patent number: 7771197
    Abstract: A handpiece for measuring root canal length having an outer sleeve that is substantially non-insulating, a connecting device, an instrument carrier, at least one transmission element within the outer sleeve, a length measuring circuit portion, a contact portion and an insulating portion. The instrument carrier is configured to receive a dental instrument. The transmission element transmits force to move the instrument carrier so that a dental instrument received in the instrument carrier executes a rotating, reciprocating and/or vibrating working movement. The length measuring circuit portion is disposed inside the handpiece and operable to transmit measuring signals for measuring length. The contact portion is operable to establish a conductive path between the dental instrument serving as an electrode and the length measuring circuit portion.

  • Patent number: 7758342
    Abstract: An apparatus that indicates a proximity of a dental instrument in a tooth's root canal to the canal's apical foramen while using the dental instrument to perform a dental/medical procedure. The apparatus includes a signal generator that provides divider signal across a first node and a third node, and a reference impedance coupled between the first node and a second node. The second node and third node include configuration for electrically coupling between a tip of the dental instrument and an electrode coupled with a body tissue of the patient, a stimulation signal being defined across the second node and the third node. The apparatus also includes a microprocessor operable to compare the stimulation signal and the divider signal, and generate a proximity signal in response to the comparison, and a proximity indicator that indicates the proximity of the dental instrument to the apical foramen in response to the proximity signal.

  • Publication number: 20100173259
    Abstract: A dental drill guide system, including a handpiece guide which interfaces with a custom surgical guide. The custom surgical guide may be designed based on patient-specific data, such as medical images, for example, and fits conformingly over at least a portion of the patient's dentition at the implant site. The handpiece guide is attachable to an existing dental handpiece, and includes a guide protrusion that interfaces with a guide receptacle of the surgical guide to position and guide the movement of the drill along a desired trajectory. The guide receptacle may have a curved shape to allow for varying the position of the handpiece to aid surgeon access in the drilling procedure.

  • Patent number: 7682151
    Abstract: The invention discloses an integrated 3 D surgical guide, guide bar, mini-implant system and a procedure to stabilize dental prostheses, based on implanting two parallel mini-implants at a given distance and then joining them by means of a prosthetic bar mounted on them, thus achieving the required strength to mount on the bar a metallic clip that retains a dental prosthesis. The advantage of this integrated system is the stabilization of dental prostheses with high precision and save standardized protocol, lower costs and less trauma for the patient than the traditionally used method.

    Abstract: An anchorage unit (41, 44) fits to a dental implant (5). A dental attachment (31, 32) for mounting to the anchorage unit comprises a first attachment part (31) and a second attachment part (32). The attachment parts (31, 32) define an aperture (24) for accommodating a portion (44) of the anchorage unit with a boundary wall of the aperture (24) on each of the attachment parts serving, in use, as a jaw for clamping against the portion of the anchorage unit. The aperture is of greater size than the portion of the anchorage unit to allow adjustment of the position of the attachment with respect to the anchorage unit. In another embodiment, a two-part anchoring assembly defines a pair of jaws for, in use, receiving and clamping against a portion of a dental attachment. The apparatus is particularly relevant when an attachment must be placed on more than one implant simultaneously.
