As a dentist performing implant therapy in Charlotte NC, I have to perform various bone grafting procedures. Bone grafting procedures can add bone tissue to a site for future implant placement. The following are some common bone grafting procedures.

Sinus elevation: This is a routine surgical procedure to regenerate bone in the upper posterior jaw. A window is made in the bone, and the floor of the maxillary sinus is elevated. Graft material is placed under the floor, and the site is allowed to heal for future implant placement. 


The first picture (above) shows an initial implant hole (osteotomy) made under the sinus floor. The second picture shows the sinus floor being pushed up with an elevation instrument. 

The first picture (above) shows a bone graft placed under the sinus floor. The second pictures shows a dental implant placed under the sinus floor into the graft material. 

Ridge preservation or socket preservation: This graft procedure is completed when a tooth is removed or extracted. If a graft is not placed, the bone will collapse and resorb (shrink), and there may not be enough bone to insert an implant in the site. By placing a graft and membrane, there usually will be enough bone for the implant after healing. Ridge preservation grafting also helps keep the extraction site free of infection because the graft and membrane can isolate the bone from the bacterial in the mouth during healing.

Ridge expansion: This is a technique of splitting a thin ridge of bone to make it wider so that an implant can be placed between the two sides of bone. 

First picture (above)shows where tooth is needed. Second picture shows initial drill hole (osteotomy) placed. Third pictures show gum tissue being retracted to access the bone.

Ridge augmentation: This routine procedure adds bone to a thin ridge. Using various techniques, the graft material is placed on the side of the thin ridge, then secured to promote bone regeneration for future implant placement. 

Block Grafting

inadequate bone for implant placement. 

Pictures shows a block of bone taken from an adjacent area (donor site) and placed in the deficient site that needs more bone for implant placement. The bone is screwed into place. The screws will be removed eventually. The donor site will eventually fill in with bone again. 

Particulate Grafting 

Pictures shows a lower jaw with inadequate bone for implant placement. 

Bleeding holes are placed in bone to promote bleeding (blood supply) to the graft material.

Particulate (granular) graft material is placed in the site. 

A membrane is placed over the granules to keep them in place.
