1. A dental implantation system to replace at least one tooth of a patient, the system comprising:

  • a dental prosthesis including a root portion and a permanent crown portion, the crown portion including an outer surface portion having a three-dimensional shape, the outer surface portion of the crown portion including one of the following;

    a lingual outer surface portion and a labial outer surface portion; and

    a custom dental splint adapted to fixate the dental prosthesis into an extraction socket located in a jaw bone of a specific patient at a desired position and inclination when the root portion of the dental prosthesis is being integrated into the extraction socket, the desired position and inclination having a geometrical relation to a pair of adjacent functional teeth of the specific patient separately located adjacent and on opposite sides of the extraction socket, the custom dental splint comprising;

    an elongate body including a tooth-facing outer surface, a non-tooth-facing outer surface opposite the tooth-facing surface, and an outer perimeter surface extending therebetween, the tooth-facing outer surface including a length having a value substantially greater than a width thereof, the non-tooth-facing outer surface including a length having a value substantially greater than a width thereof, the width of the tooth-facing surface and the width of the non-tooth-facing surface being greater than a width of the outer perimeter surface, an extent of the width and an extent of the length of the tooth-facing and non-tooth-facing surfaces being both dimensioned to be sufficiently small so as to not extend beyond an incisal surface of either of the pair of adjacent functional teeth when the respective tooth is an anterior tooth and so as to not extend beyond an occlusal surface of either of the pair of adjacent functional teeth when the respective tooth is a posterior tooth, the tooth-facing outer surface further including;

    a first tooth-facing outer surface portion adapted to adhesively bond to the outer surface portion of the permanent crown portion of the dental prosthesis and having a first custom three-dimensional surface shape dimensioned to substantially match the three-dimensional shape of the outer surface portion of the permanent crown portion of the dental prosthesis, the first tooth-facing outer surface portion having the first custom three-dimensional surface shape prior to insertion of the dental prosthesis into the extraction socket, prior to application of bonding material to the first tooth-facing outer surface portion, and prior to bonding attachment of the first tooth-facing outer surface portion to the outer surface portion of the permanent crown portion of the dental prosthesis,a second tooth-facing outer surface portion adapted to adhesively bond to an outer surface portion of a crown of a first one of the pair of adjacent functional teeth defining a first adjacent tooth and having a second custom three-dimensional surface shape dimensioned to substantially match a three-dimensional shape of the outer surface portion of the crown of the first adjacent tooth, the second tooth-facing outer surface portion having the second custom three-dimensional surface shape prior to insertion of the dental prosthesis into the extraction socket, prior to application of bonding material to the second tooth-facing outer surface portion, and prior to bonding attachment of the second tooth-facing outer surface portion to the outer surface portion of the crown of the first adjacent tooth, the outer surface portion of the crown of the first adjacent tooth being one of the following;

    a lingual outer surface portion and a labial outer surface portion, anda third tooth-facing outer surface portion adapted to adhesively bond to an outer surface portion of a crown of a second one of the pair of adjacent functional teeth defining a second adjacent tooth and having a third custom three-dimensional surface shape dimension to substantially match a three-dimensional shape of the outer surface portion of the crown of the second adjacent tooth, the third tooth-facing outer surface portion having the third custom three-dimensional surface shape prior to insertion of the dental prosthesis into the extraction socket, prior to application of bonding material to the third tooth-facing outer surface portion, and prior to bonding attachment of the third tooth-facing outer surface portion to the outer surface portion of the crown of the first adjacent tooth, the outer surface portion of the crown of the second adjacent tooth being one of the following;

    a lingual outer surface portion and a labial outer surface portion.
