Informed Consent for Dental Implant Placement

Patient and Provider Information

Nature and Purpose of the Procedure

A dental implant is a sterile, biocompatible titanium or zirconia post that is surgically placed into the jawbone to serve as an artificial tooth root for a missing tooth or teeth. The procedure is performed under local anesthesia, with sedation available. An incision is made in the gingiva overlying the edentulous site, the bone is exposed, and a series of precision drills of progressively larger diameter are used to create an osteotomy (drill site) in the bone to the planned depth and diameter. The implant fixture is threaded into the osteotomy and a healing abutment or cover screw is placed. The gingiva is sutured over or around the implant. The critical healing phase — osseointegration — is the biological process by which bone cells grow into the porous titanium surface and create a stable biological bond. This process takes 2 to 6 months depending on bone density, implant site, and patient-specific healing factors. Once osseointegration is confirmed, an abutment and final crown, bridge, or overdenture prosthesis is fabricated by the restorative dentist. Bone grafting (guided bone regeneration with autologous or synthetic bone) may be required prior to or at the time of implant placement if jawbone volume is insufficient. Sinus augmentation (sinus lift) is required for posterior upper jaw implants with inadequate vertical bone height above the maxillary sinus floor.

Material Risks and Potential Complications

Implant failure (failure to osseointegrate): occurs in 2 to 5 percent of implants, more commonly in smokers, patients with poorly controlled diabetes, those with low bone density, or where inadequate primary stability was achieved. Failed implants must be removed; re-implantation may be attempted after healing.
Peri-implantitis: a destructive inflammatory condition around the implant analogous to periodontitis, characterized by progressive bone loss, bleeding on probing, and suppuration. Affects 10 to 20 percent of implants at 10 years in some studies. May lead to implant loss if untreated.
Inferior alveolar nerve (IAN) injury: mandibular implants placed in the posterior lower jaw carry a risk of nerve contact if the implant is placed too close to the mandibular canal, causing permanent numbness, tingling, or pain in the lower lip, chin, and teeth. CBCT imaging is routinely used to assess safe distances.
Maxillary sinus perforation or sinusitis: upper jaw implants may perforate the sinus floor, particularly when sinus lift grafting is not performed or graft material migrates into the sinus, causing chronic sinusitis or oroantral communication.
Infection: post-surgical implant site infection may cause early implant failure and requires antibiotic treatment and potentially implant removal.
Bone graft resorption: bone graft material used to augment deficient sites may resorb partially or completely, resulting in insufficient bone for stable implant placement.
Adjacent tooth or root injury from the drilling procedure, which may require endodontic treatment of the affected tooth.
Implant or prosthetic component fracture: implant body fracture, abutment screw loosening or fracture, and ceramic crown chipping are long-term mechanical complications requiring component replacement.
Delayed healing in patients with medical conditions (uncontrolled diabetes, osteoporosis treated with bisphosphonates, history of head and neck radiation) may significantly impair osseointegration or cause osteonecrosis of the jaw (MRONJ) in bisphosphonate-treated patients.

Patient Obligations and Lifestyle Requirements

Dental implant success is heavily influenced by patient behaviour. Patients must commit to: (1) cessation of smoking during the healing phase (and ideally permanently), as smoking reduces implant survival rates by 30 to 50 percent; (2) optimal blood glucose control in diabetic patients (HbA1c below 7.0 percent preferred); (3) meticulous daily oral hygiene including interdental brushing and water flossing around implant components; (4) regular professional maintenance appointments every 3 to 6 months; (5) wearing an occlusal night guard if bruxism is identified, to prevent implant and prosthetic overload.

Alternatives to Implant Placement

Fixed dental bridge: a tooth-supported prosthesis that crowns the adjacent teeth (abutment teeth) and spans the gap with a false tooth (pontic). Avoids surgery but requires irreversible reduction of healthy adjacent teeth.
Removable partial or complete denture: removable prosthesis replacing missing teeth. No surgery required; lower cost; but associated with bone resorption, reduced chewing efficiency, and less patient satisfaction than implants.
No replacement: acceptable for asymptomatic cases but results in progressive bone resorption, supraeruption of opposing teeth, and drifting of adjacent teeth over time.

Expected Benefits

The primary expected benefit of dental implant placement is the restoration of a missing tooth or teeth with a stable, functional prosthesis that closely mimics natural tooth function and appearance. Unlike removable dentures, implants are fixed in the jawbone and do not require adhesives. Successful osseointegration provides a long-term solution with studies demonstrating 10-year survival rates of 94 to 98 percent in healthy, non-smoking patients. Implants also help preserve the jawbone by preventing disuse bone resorption that occurs following tooth loss.

Medication-Related Osteonecrosis of the Jaw (MRONJ) Disclosure

Patients who are taking or have taken bisphosphonate medications (e.g., alendronate/Fosamax, zoledronic acid/Zometa, risedronate/Actonel) for osteoporosis, Paget's disease, or cancer are at elevated risk for medication-related osteonecrosis of the jaw (MRONJ). MRONJ is characterized by exposed jawbone that fails to heal following dental surgery, which can lead to chronic pain, infection, and significant bone loss. If you are taking or have taken bisphosphonates, you must disclose this to your provider. The risk is substantially higher with intravenous bisphosphonates used in oncology (zoledronic acid, pamidronate) than with oral formulations. Your provider may request a drug holiday, medical clearance, or recommend against implant placement in high-risk cases.

Right to Refuse or Withdraw Consent

You have the right to refuse this procedure or withdraw your consent at any time before the procedure begins without penalty or adverse effect on your dental care. Your provider will discuss alternative prosthetic options with you if you choose not to proceed.

Questions and Understanding Confirmation

I confirm that I have disclosed all medications, supplements, and health conditions to my provider, including bisphosphonate use and smoking status. I understand the osseointegration timeline, maintenance obligations, and long-term success factors. All my questions have been answered to my satisfaction.

Language Access and Interpreter Services

If English is not your primary language or if you require assistance communicating, a qualified interpreter is available at no cost. Please notify your care team before signing this document.
