The merged information is used to generate a three-dimensional shape of the bone to be regenerated, a three-dimensional position of the missing tooth/teeth, and a three-dimensional model of the customized resorbable three-dimensional scaffold for oral and maxillofacial bone grafting. The three-dimensional model is used to generate the customized resorbable three-dimensional scaffold and resorbable connectors for the customized resorbable three-dimensional scaffold. ## Claims ### Claim 1 A method for making a customized and resorbable three-dimensional scaffold for oral and maxillofacial bone grafting, the method comprising: obtaining two different sets of three-dimensional information obtained from a patient, wherein a first set of the two different sets includes three-dimensional bone information and a second set of the two different sets includes three-dimensional teeth and tissue information;
