A system including an ablation probe tip and a virtual stent, said ablation probe tip for use in a tooth bud ablation procedure that results in tooth agenesis, said tooth bud having a middle, said ablation probe tip for use with an ablation probe unit, said system comprising:
- (a) said ablation probe tip having a shaft, said shaft having an insertion end for inserting into a tooth bud and a connection end for connecting said ablation probe tip to said ablation probe unit, said ablation probe tip having at least one movement transmitting sensor;
- (b) said ablation probe tip having a center of ablation;
- (c) said virtual stent having a display with at least one virtual surgical guide angle marking displayed thereon;
- (d) said ablation probe tip being guidable at a pre-defined angle when used in conjunction with said virtual stent as said at least one movement transmitting sensor transmits a real-time representation of said ablation probe tip to said display;
- and
- (e) said ablation probe tip being depth limited by stop information to a pre-defined depth;
- wherein said center of ablation substantially coincides with or overlaps with said middle of said tooth bud when said ablation probe tip is guided at said pre-defined angle to said pre-defined depth.
An ablation probe tip, said ablation probe tip for use in a tooth bud ablation procedure that results in tooth agenesis, said tooth bud having a middle, said ablation probe tip for use with a stent, said ablation probe tip for use with an ablation probe unit, said ablation probe tip comprising:
- (a) said ablation probe tip having a shaft, said shaft having an insertion end for inserting into a tooth bud and a connection end for connecting said ablation probe tip to said ablation probe unit;
- (b) said ablation probe tip having a center of ablation between said insertion end and said connection end;
- (c) said ablation probe tip being guidable at a pre-defined angle when used in conjunction with said stent;
- (d) said ablation probe tip being depth limited by stop information to a pre-defined depth;
- (e) said ablation probe tip having a shaft inner conductor, shaft insulation surrounding said shaft inner conductor, a shaft outer shield surrounding said shaft insulation, a window defined in said shaft outer shield, a shaft outer cover surrounding said shaft outer shield and said window, and a reflector positioned between said window and said insertion end, said center of ablation positioned in said shaft inner conductor at said window;
- and
- (f) said center of ablation being a focal point from which ablation means radiates through said window, at least part of said ablation means reflected from said reflector;
- wherein said center of ablation substantially coincides with or overlaps with said middle of said tooth bud when said ablation probe tip is guided at said pre-defined angle to said pre-defined depth.
