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.
Claims12
A dental tray set comprising:
- a base frame that is designed on a dental model containing surface information of gum tissue area and an exposed bone structure of a particular patient, the base frame being operable to engage at least one area of a patient's jawbone and further being operable to engage at least one area of a patient's gum tissue the base frame further having an exterior surface;
- and
- at least one surgical guide section having an exterior surface that extends over at least a portion of the exterior surface of the base frame, and that is attachable to the base frame;
- wherein the combination of the base frame and the at least one surgical guide section engage both the at least one area of a patient's jawbone and also engage the at least one area of a patient's gum tissue;
- wherein the base frame includes two spaced-apart base portions, an arm distinct from the stabilizing arm disposed therebetween, and a stabilizing arm extending from each of the base portions, each of the stabilizing arms being pliable and operable to exert an inwardly facing force on a jawbone at a plurality of contact points, the contact points laterally spaced along each stabilizing arm, at least one of the laterally spaced contact points of at least one stabilizing arm positioned and configured to contact a partially exposed jawbone.
