A drill burr includes a channel, extending along a longitudinal axis of the drill burr, and fluidically connected to a water reservoir for providing a constant-flow liquid jet. The constant-flow liquid jet has a first pressure directed at the bone along the longitudinal axis of the drill burr. A pressure sensor senses a pressure change in the liquid jet from the first pressure to a second pressure. A signal processing unit is configured to translate the pressure change into information indicating a structural change in the bone along the drilling path, from a first structure to a second structure, corresponding respectively to the first pressure and the second pressure. Optionally, the signal processing unit generates an audio alarm notifying of the structural changes.

Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. Custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses.

A system of components or implements for easily and precisely installing a dental implant, and a method of installing the dental implant, within a patient's jaw, is disclosed. The system comprises a rotary cutter guide and a rotary cutter. Orthogonal slots are defined within the rotary cutter guide so as to precisely position the rotary cutter within the rotary cutter guide as well as to permit the rotary cutter to form slots within a patient's jaw so as to accommodate winged members of a winged dental implant. A method of installation is also disclosed, and the system and method may be utilized in conjunction with the installation of both a single winged implant or a dual winged implant wherein the two winged implants are connected together by means of a connecting bar or plate.

A dental impression that includes an underside and a connecting part. The underside has a negative form of at least one partial area of a jaw and at least one implant site located in the partial area of the jaw. The connecting part is a recess arranged on an upper surface of the dental impression opposite the underside in the area of the negative form of the implant site, and has a longitudinal axis defined along a depth direction of the recess. The recess has a geometry that is rotationally asymmetric about the longitudinal axis, and an external contour of the connecting part is asymmetrical in a plane perpendicular to the longitudinal axis of the connecting part. The connecting part has a lowered base as a depth stop, the lowered base being within the recess and below the upper surface of the dental impression.

A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.

A drill limit system includes a holder having drill stops removably coupled thereto and configured to receive a drill bit therethrough, and a platform coupled to the holder and configured to engage a tip end of the drill bits when received through the drill stops, wherein the holder and platform are movable relative to each other so that the position of the drill stops relative to the drill bits may be selectively varied. A method for attaching drill stops to a drill bit includes providing a holder and a platform movable relative to each other, the holder having a plurality of drill stops removably coupled thereto, inserting a plurality of drill bits through respective drill stops, moving the holder and platform relative to each other to select a desired height of the drill stops on the bits, and engaging the drill stops to the drill bits at the selected height.

A dental surgery guide system for use with a dental handpiece for forming a bore in a patient's jaw bone to receive a dental implant comprises a surgical template and a handpiece jig; the top of the handpiece guide can slide below the top of the template guide rail.

A series of a palatal expanders increasing width can be used to gradually expand a patient's palate. Each palatal expander may have a palatal region flanked by teeth regions. The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.

Embodiments of the disclosure relate to implantable objects and guiding devices, as well as recipient site preparation instruments, bone-implantable materials, and methods of fabrication and use thereof.

Dental implants for fixed and removable prosthetic devices, having application to single tooth replacement, e.g., caps and crowns, and multiple tooth replacement using one or more implants, e.g., bridges, and multiple implants for full and partial prosthetic devices. Dental implants include an implant and an abutment configured to mate with the implant in a non-rotatable fashion. The implant may have a cylindrical or a non-cylindrical shape. In one embodiment, the dental implant includes a first stage implant and a second stage implant. The second stage implant is interconnectable to the first stage implant and includes an abutment with an anatomical emergence profile. Further, dental reconstruction and abutment installation methods utilizing the dental implant systems and instruments are disclosed. Also provided are impression taking procedures, and impression copings that produce an accurate fit between the dental prosthesis and the dental implant.
