Therapeutic tooth bud ablation
Ablation probe tips ( 108, 148, 320, 360 ) and physical and virtual stents ( 110 ) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.
1. An ablation method for ablating tissue using a virtual stent, said method comprising the steps of:
(a) providing said virtual stent and a movement sensored ablation probe tip, said movement sensored ablation probe tip having an insertion end and a connection end, said movement sensored ablation probe tip having a center of ablation;
(b) providing at least one volume scan;
(c) providing at least one virtual surgical guide angle, said at least one virtual surgical guide angle providing angle guidance to guide said movement sensored ablation probe tip at a pre-defined angle; and
(d) providing at least one virtual stop, said at least one virtual stop providing stop information to limit the depth of said movement sensored ablation probe tip to a pre-defined depth;
(e) introducing said movement sensored ablation probe tip to said tissue;
(f) using said at least one virtual surgical guide angle and said at least one virtual stop, guiding said movement sensored ablation probe tip towards the position where said center of ablation is substantially within said tissue; and
(g) using ablation means, ablating said tissue when said center of ablation is within said tissue.
2. The method of claim 1 , further comprising the step of providing a display on which representations of said movement sensored ablation probe tip having a center of ablation, said at least one virtual surgical guide angle, and said at least one virtual stop are displayed.
3. The method of claim 1 , further comprising the step of providing a display on which representations of said at least one volume scan, said movement sensored ablation probe tip having a center of ablation, said at least one virtual surgical guide angle, and said at least one virtual stop are displayed.
4. The method of claim 1 , further comprising the steps of:
(a) providing a display;
(b) displaying said at least one volume scan on said display; and
(c) overlaying on said at least one volume scan at least one representation selected from the group consisting of:
(i) a representation of said movement sensored ablation probe tip having a center of ablation;
(ii) a representation of said at least one virtual surgical guide angle; and
(iii) a representation of said at least one virtual stop.
5. The method of claim 1 , further comprising the steps of:
(a) providing a display;
(b) displaying said at least one volume scan on said display;
(c) overlaying on said at least one volume scan displayed on said display at least one representation selected from the group consisting of:
(i) a representation of said at least one virtual surgical guide angle; and
(ii) a representation of said at least one virtual stop; and
(d) displaying a real-time representation of said movement sensored ablation probe tip having a center of ablation overlaid on said at least one volume scan displayed on said display.
6. The method of claim 1 , said step of guiding said movement sensored ablation probe tip being performed manually.
7. The method of claim 1 , said step of guiding said movement sensored ablation probe tip being performed automatically.
8. The method of claim 1 , wherein said step of ablating results in tooth agenesis.
9. The method of claim 1 further comprising the step of providing indications to indicate that said center of ablation is within said tooth bud.
10. The method of claim 1 , during said step of ablating said tooth bud, monitoring progress of the ablating, and providing constant feedback pertaining to said progress.
11. The method of claim 1 further comprising the step of providing monitoring and overriding safeguards to allow automatic cessation of ablation.
12. The method of claim 1 further comprising the step of providing monitoring and overriding safeguards to allow manual cessation of ablation.
13. The method of claim 1 further comprising the step of ceasing the delivery of ablation means.
14. The method of claim 1 further comprising the step of preventing activation until said center of ablation is within said tooth bud.
15. The method of claim 1 , wherein said tissue is a lesion or a tumor.
