1. A dental drill bit configured to drill a particularly shaped socket in a portion of a tooth and a portion of a human jawbone, the socket being particularly shaped to receive a dental implant and an abutment therein, said dental drill bit comprising:
a cutting head, said cutting head comprising:
a first portion with a proximal end and a distal end; and
a second portion with a proximal end and a distal end, said proximal end of said second portion being positioned adjacent to said distal end of said first portion;
wherein said first portion of said cutting head is formed into a bullet shape, and comprises:
a plurality of flutes;
wherein each of said plurality of flutes is configured to cut away a first portion of the tooth and the portion of the human jawbone when said cutting head is rotated about the axis of said dental drill bit; and
wherein said plurality of flutes of said bullet-shaped first portion are configured to form a bullet-shaped socket portion when rotated about the axis of said dental drill bit, the bullet-shaped socket portion being shaped to match a shape of the dental implant;
wherein said second portion comprises: a spherical frustum shape defined by a first plane that coincides with the equatorial plane of the sphere, and a second plane;
wherein said spherical frustum-shaped second portion comprises: a cutting surface formed with diamond particles;
wherein said diamond particles of said cutting surface on said spherical frustum-shaped second portion are configured to form a spherical frustum-shaped socket portion in a second portion of the tooth, when said cutting head is rotated about the axis of said dental drill bit, being shaped to match at least a portion of a spherical surface of the abutment, without fracturing or chipping of the second portion of the tooth during drilling with said dental drill bit; and
wherein said bullet shape of said first portion is defined by:
an arc segment positioned co-planar with respect to the axis of said dental drill bit and revolved around the axis of said dental drill bit, said arc segment having a first end being coextensive with, and perpendicular to, said second plane, and a second end terminating at the axis of said dental drill bit; and
a radius of said arc segment being greater than a distance between said first end of said arc segment and the axis of said dental drill bit.
