Dental implants have become the gold standard for tooth replacement, but not every patient has the ideal bone structure needed for successful implant placement. In such cases, bone grafts or sinus lifts may be required to create a stable foundation for the implant. These procedures are critical to ensuring the long-term success of dental implants and particularly for All-on-4 full-arch cases where posterior bone is often deficient.
What Is Bone Grafting?
Bone grafting is a procedure used to increase the volume or density of bone at the site where a dental implant will be placed. The goal is to ensure that there is sufficient bone mass to support the implant securely. There are several types of bone grafts used in dentistry: autogenous grafts (bone taken from the patient's own body, often from the chin or jaw); allograft (donor bone from a human tissue bank); xenograft (bone derived from animal sources, typically bovine — Bio-Oss is the most widely used); and alloplastic graft (synthetic bone substitutes). At Dazzle, the graft type is selected based on the defect size, location, and clinical requirements.
What Is a Sinus Lift?
A sinus lift (or sinus augmentation) is a surgical procedure that adds bone to the upper jaw in the area above the molars and premolars. The sinuses (air-filled cavities above the upper back teeth) expand when these teeth are lost, limiting the available bone height for implant placement. A sinus lift elevates the sinus floor and places bone graft material in the created space. See our sinus lift vs bone graft guide for a full clinical comparison of both procedures.
Why Are These Procedures Needed?
After tooth extraction, bone at the extraction site resorbs progressively. Within the first year, significant bone volume is lost. For implant placement, a minimum bone width and height are required. When bone has resorbed below these minimums, augmentation restores the conditions needed for implant placement. Without augmentation, an implant placed in deficient bone will fail to achieve primary stability or will be positioned incorrectly for the planned prosthesis.
The Procedure
Bone grafting at Dazzle is performed under local anaesthesia with sedation available. A small incision is made at the graft site; the graft material is placed; a collagen membrane covers the graft to prevent soft tissue ingrowth; the site is sutured. Healing time before implant placement: 4–6 months for horizontal ridge augmentation; 6–8 months for lateral window sinus lift.
What to Expect After the Procedure
Post-operative care is similar to implant surgery. Swelling, mild discomfort, and minor bleeding are expected for 3–5 days and are managed with prescribed medications. Avoid strenuous physical activity and smoking during healing.
