Introduction: A lateral maxillary sinus lift procedure, also known as a sinus augmentation, is a surgical procedure designed to increase the amount of bone in the upper jaw, particularly in the molar and premolar areas. The procedure involves lifting the sinus membrane and grafting bone into the sinus floor to allow for the placement of dental implants. This consent form outlines the plan, alternatives, risks, and questions associated with the lateral maxillary sinus lift procedure.
Plan: The procedure will be carried out by the qualified medical team. The plan for the lateral
maxillary sinus lift procedure involves:
• Preoperative Evaluation: Including imaging studies such as X-rays or CT scans to assess
the existing bone structure and sinus anatomy.
• Administration of Anesthesia: Local or general anesthesia will be administered as
needed for comfort during the procedure.
• Surgical Incision: An incision will be made along the gumline to lift the gingiva and
expose the maxillary bone.
• Removal of Bone: Using a surgical drill or piezotome, a window will be created into the
maxillary sinus to expose the sinus membrane.
• Surgical Lifting of the Sinus Membrane: Careful lifting of the sinus membrane to create
space for the bone graft.
• Placement of Bone Graft Material and PRF: Graft material, along with Platelet-Rich Fibrin
(PRF) if applicable, will be placed to augment the existing bone. This will support future
implant placement.
• Closure of the Surgical Site: The incision will be closed with sutures, and proper aftercare
instructions will be provided, including details on medications, activity restrictions, and follow-up appointments.
• In some situations, an implant may be placed simultaneously with the lateral sinus lift;
however, this procedure is typically conducted in two stages. The implant is most often
placed 4-6 months after the completion of the lateral sinus lift surgery, allowing
adequate time for the bone graft to integrate and heal.
Bone Grafting, Tissue Grafting, and Platelet Rich Fibrin (PRF), Use:
In this procedure, materials like bone grafting, Platelet Rich Fibrin (PRF), may be necessary
before implant placement if the jawbone lacks adequate thickness. These factors will be
evaluated and discussed during your consultation.
• Allograft Bone Graft: There might be situations where a bone graft is required. An
allograft bone graft involves the use of human donor bone, which is treated to ensure
safety and compatibility, to augment the area around the implant. This procedure is
performed to replace bone lost to peri-implantitis and to provide robust support for the
implant. Since the graft is derived from a human source, it carries a low risk of rejection
or infection and integrates well with your own body tissues. Donor bone used for
grafting is processed in strict compliance with regulations set by the Food and Drug
Administration (FDA) and the American Association of Tissue Banks (AATB). Synthetic
grafting materials, including a blend of tricalcium phosphate and hydroxyapatite, are also
used. However, synthetic bone integration is generally slower and less efficient
compared to donor bone, potentially resulting in delayed bone healing.
• Platelet Rich Fibrin (PRF): PRF is a product derived from your own blood platelets and
growth factors. This is obtained by processing a blood sample in a centrifuge. The PRF is
then applied to the surgical area to promote faster healing and recovery. The growth
factors present in PRF stimulate tissue regeneration, and the fibrin forms a scaffold for
the growth of new bone and soft tissue.
Alternatives: Alternatives to a lateral maxillary sinus lift may include:
• Using shorter or angled implants without a sinus lift.
• Traditional dentures or bridges.
• No treatment, accepting the current dental condition. Patients should understand the
benefits, limitations, and risks associated with these alternatives.
Risks: Risks and potential complications associated with a lateral maxillary sinus lift procedure
include but are not limited to:
• Sinus Membrane Perforation: As detailed previously, tearing or cutting of the
membrane may occur.
• Infection: Postoperative infection requiring antibiotics or additional treatment.
• Bleeding: Excessive bleeding during or after the procedure.
• Chronic Sinus Issues: As mentioned earlier, this may lead to long-term sinus problems.
• Graft Failure: The bone graft may fail to integrate, requiring additional procedures.
• Graft migration: The graft may become dislodged and require additional surgery to
recover.
• Nerve Damage: Temporary or permanent altered sensation in the affected area.
• Adverse Reaction to Anesthesia: Allergic or other reactions to anesthesia or other
medications used.
• Risk of Sinus Exposure and Damage: As detailed previously.
• Other unforeseen complications or risks specific to the patient’s situation.
Questions: It is essential that patients fully understand the procedure, alternatives, and risks. All
questions should be thoroughly discussed with the Doctor.
Consent: I, the undersigned, have read and understood this informed consent form. I have had
the opportunity to ask all questions, and all questions have been answered to my satisfaction. I
hereby consent to the lateral maxillary sinus lift procedure as described above, understanding
all associated risks and alternatives.
