       4 . Set of motor-driven instruments to aid the fixing of dental implants according to  claim 1 , wherein the connector ( 14 ) possesses motor functions and comprises an extension ( 6 ) for its connection to a surgical motor.  
   
   
       5 . Set of motor-driven instruments to aid the fixing of dental implants according to  claim 1 , wherein the connector ( 17 ) possesses extractor functions and comprises a coupling area ( 15 ) for connection to a ratchet wrench.  
   
   
       6 . Procedure to facilitate the fixing of dental implants wherein during said fixing process the set of motor-driven instruments according to  claim 5  is used.  
   
   
       7 . Set of motor-driven instruments to aid the fixing of dental implants according to  claim 3 , wherein the connector ( 14 ) possesses motor functions and comprises an extension ( 6 ) for its connection to a surgical motor.  
   
   
       8 . Set of motor-driven instruments to aid the fixing of dental implants according to  claim 3 , wherein the connector ( 17 ) possesses extractor functions and comprises a coupling area ( 15 ) for connection to a ratchet wrench.  
   
   
       9 . Procedure to facilitate the fixing of dental implants wherein during said fixing process the set of motor-driven instruments according to  claim 1  is used.  
   
   
       10 . Osteotome ( 4 A,  4 B,  4 C,  4 D) applicable in techniques that modify the bone structure in a suitable way before receiving a dental implant, wherein the osteotome comprises an apical end ( 10 ) followed by a threaded conical sention ( 9 ) and a threaded cylindrical section ( 8 ), said threaded conical section being finished by an adjustment area ( 7 ) to which a manually-driven or motor-driven connector ( 14 ,  17 ) can be connected.  
   
   
       11 . Osteotome ( 4 A,  4 B,  4 C,  4 D), according to  claim 10 , wherein the adjustment area ( 7 ) comprises a polygonal projection ( 13 ) which is capped by a cylindrical projection that creates a circular recess in which an O-ring seal ( 11 ) is housed.  
   
   
       12 . Osteotome ( 4 A,  4 B,  4 C,  4 D), according to  claim 11 , wherein the poligonal projection ( 13 ) is hexagonal.
