Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. Custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses.

A changeable positioning device for dental drilling comprises a base, a guide body and a positioning block.

The invention could comprise a bone foundation guide system and a method for same, the bone foundation guide system having a bone foundation guide comprising a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site, the body being further contoured accept and to guide the cutting of a portion of the bone segment from a dental implant surgical site and as well as to alternatively support a dental implant surgical guide; the dental implant surgical guide; and a bone foundation guide prosthesis as an alternative to the dental implant surgical guide, the bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

An approach is disclosed that involves creating an updated master dental model of a patient's mouth after an implant surgery by aligning new postoperative oral scan data to pre-existing preoperative oral scan data that is more comprehensive (e.g., it includes bite registration). Before surgery a multi-piece stackable surgical guide set is created using the preoperative oral scan data. The surgical guide set is used to facilitate the surgery. After the surgery at least one piece of the surgical guide set is placed back in a patient's mouth and may act as a reference marker because it was created using the preoperative oral scan data, but is also part of the postoperative mouth configuration since it was used to facilitate the surgery. The affected portion of the mouth may then be digitally scanned directly or indirectly by way of a physical impression with the reference marker in place to determine the new characteristics resulting from the surgery such as new implant installation locations and orientations. The new postoperative oral scan data may be combined with the pre-existing preoperative oral scan data by way of the reference marker (since it is a constant between the two sets of scan data) without having to do such things as take a new bite registration, on which a new implant restoration can be easily created.

A combination of a guide sleeve for a surgical template, a drill, and a thread forming tool is disclosed. The guide sleeve has a guide surface for guiding the thread forming tool.
