Dental tools system and method

Abstract

A dental tools system with a plurality of guide tabs; a mold and a plurality of tissue punch heads. The mold has a plurality of mold holes, each mold hole having a top portion and a bottom portion. Each guide tab fits in the top portion of one of the mold holes and each tissue punch head fits in the top portion of one of the mold holes. A method of placing dental implants is also described.

1 . A mold comprising:
 a plurality of mold holes, each mold hole comprising a top portion and a bottom portion,
 wherein the mold comprises
 a mold base, which comprises the bottom portions of the mold holes; 
 a mold superstructure, which comprises the top portions of the mold holes, each top portion having a cross section which decreases in a direction towards the mold base, and 
 
 wherein the mold base and the mold superstructure may be engaged in more than one operation position so that some top portions match with bottom portions in each operation position. 
   
     
     
         2 . The mold according to  claim 1 , wherein the mold base comprises first positioning means and the mold superstructure comprises second positioning means suitable for interacting with the first positioning means in a stable position to keep constant the relative position of the mold base and the mold superstructure. 
     
     
         3 . The mold according to  claim 2 , wherein the first positioning means and the second positioning means have more than one stable position. 
     
     
         4 . The mold according to  claim 3 , wherein the mold superstructure comprises a first frame and a first insert, the first insert comprising the top portions of the mold holes and being inserted inside the first frame, and wherein the mold base comprises a second frame and a second insert, the second insert comprising the bottom portions of the mold holes and being inserted inside the second frame. 
     
     
         5 . The mold according to  claim 3 ,
 wherein
 the mold superstructure comprises a first frame and a first insert, the first insert comprising the top portions of the mold holes and being inserted inside the first frame; and 
 the mold base comprises a second frame with insert holes, each insert hole comprising a seat; and 
 the mold base further comprises a plurality of individual fitting inserts, each one of these individual fitting inserts being adapted to fit in at least one of the insert holes of the second frame, each individual fitting insert comprising a body and one of the bottom portions, and a wing, wherein each individual fitting insert is adapted to fit in the seat of one of the insert holes in such a way that the shape of the seat prevents the individual fitting insert from rotating once the individual fitting insert is fitted into the seat. 
   
     
     
         6 . The mold according to  claim 5 , wherein each individual fitting insert is secured to the second frame by means of a retention screw. 
     
     
         7 . The mold according to  claim 5 , wherein the wing of at least one individual fitting insert comprises one shoulder cavity adapted to receive at least part of a shoulder of a healing abutment. 
     
     
         8 . The mold according to  claim 5 , wherein the second positioning means are located in the first frame, and wherein one of the first and second positioning means comprises a concavity and the other of the first and second positioning means comprises at least one of a ball with spring, a convexity, or a plate. 
     
     
         9 . The mold according to  claim 5 , wherein some bottom portions are oriented in a different direction from some top portions. 
     
     
         10 . The mold according to  claim 5 , wherein each individual fitting insert and its bottom portion are one piece. 
     
     
         11 . The mold according to  claim 5 , wherein the top portions have an inferior zone with a cross section which varies in size and/or shape in the direction towards the mold base, in such a way that the shape of the inferior zone of the top portion is different from the shape of the rest of the top portion. 
     
     
         12 . The mold according to  claim 5 , wherein some of the top portions have at least one cross section which comprises a straight portion and a curved portion. 
     
     
         13 . The mold according to  claim 5 , wherein the top portions have a regular surface, as that which may be expressed by a polynomic, exponential or logarithmic mathematical formula, or a combination thereof, with a mean roughness Ra lower than 10 μm. 
     
     
         14 . The mold according to  claim 5 , further comprising detachable inserts suitable for modifying the final profile of some top and/or bottom portions. 
     
     
         15 . The mold according to  claim 5 , wherein the mold base comprises the bottom portions of the mold hole, the bottom portions being suitable for housing a prosthetic connection of a healing abutment or an impression post, and wherein the housing is achieved by means of snap on coupling and/or couple threading with or without the use of a retention screw. 
     
     
         16 . A method of fabricating a custom healing abutment and/or impression post, the method comprising:
 providing the mold according to  claim 5 ;   identifying a suitable top portion of a mold hole from the mold holes with the use of a guide tab or a virtual guide tab;   placing an abutment core into the suitable mold hole;   pouring a biocompatible and curable material into the open space of the suitable mold hole so that at least part of the open space is filled;   removing the custom healing abutment after the biocompatible and curable material is cured and set; and   coupling the healing abutment with an implant in order to establish and maintain a gingival emergence profile.   
     
     
         17 . The method of  claim 16 , further comprising:
 replacing the custom healing abutment with a custom impression post having a same shape and size custom body;   generating an impression;   introducing a silicon mask around the custom impression post present in the impression;   pouring stone into the impression and generating a working cast; and   fabricating an implant crown comprising an emergence profile similar to the gingival emergence profile.
