Abstract

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.

Claims24

Dependent claims

A dental tray set comprising:

a base frame having an arcuate shaped structure with an inner lateral surface and an outer lateral surface, the inner lateral surface defining at least one outer-lateral contact configured to selectively engage a corresponding outer lateral surface of one of a gum tissue area and a bone structure of a patient mouth in an initial installed orientation without obstructing a surgical site region of a top ridge of a patient jaw, an uppermost surface of the arcuate shaped structure sized to terminate below the top ridge when in the initial installed orientation, the base frame being further formed to include a fixed first connector element;
and
at least one attachment having an exterior surface that extends over at least a portion of the uppermost surface of the arcuate shaped structure of the base frame and that is attachable to the base frame using a fixed second connector element selectively engaging the first connector element to align the at least one attachment with the base frame;
wherein the at least one attachment is configured to obstruct at least a portion of the surgical site region of the top ridge;
wherein the dental tray set is configured to engage the at least one of the gum tissue area and the bone structure;
and
wherein the base frame and the at least one attachment are configured to be fully received in the patient mouth in an assembled orientation.

A dental tray set, comprising:

a base frame having an arcuate shaped structure with two opposing arms and a central portion disposed therebetween, the arcuate shaped structure further having an inner lateral surface and an outer lateral surface, a first lateral contact associated with a first arm of the two opposing arms and a second lateral contact associated with a second arm of the two opposing arms, the lateral contacts configured to selectively engage one of a corresponding outer lateral surface and a corresponding inner lateral surface of one of a gum tissue area and a bone structure of a patient mouth in an initial installed orientation without obstructing a surgical site region of a top ridge of a patient jaw, an uppermost surface of the arcuate shaped structure sized to terminate below the top ridge when in the initial installed orientation, and the uppermost surface selectively representing a bone reduction jig such that, in a final installed orientation when there is a shaved section, the uppermost surface corresponds to the top ridge, the base frame being further formed to include at least two fixed first connector elements, each of which is disposed on a separate opposing arm of the two opposing arms;
at least one anchor device;
and
at least one attachment having an exterior surface that extends over at least a portion of the uppermost surface of the arcuate shaped structure of the base frame and that is attachable to the base frame using at least two fixed second connector elements selectively engaging the at least two first connector elements to align the at least one attachment with the base frame, the at least one attachment configured to obstruct at least a portion of the surgical site region of the top ridge;
wherein the base frame is configured to engage the at least one of the gum tissue area and the bone structure by way of the at least one anchor device;
and
wherein the base frame and the at least one attachment are configured to be fully received in the patient mouth in an assembled orientation.
