Are Dental Implants
Safe?

The published safety record

Dental implants have been in routine clinical use since the 1970s, with continuous refinement of materials and techniques. Across the published literature:

- 5-year success rate: 95–98% in healthy adults at non-augmented sites - Serious complication rate: approximately 1–2% (nerve injury, sinus involvement, deep infection) - Implant failure rate: approximately 2–5% over 5 years

This makes implants safer than many routinely-accepted medical procedures. The risk profile is well-understood, and most complications are predictable and preventable through proper case selection, surgical technique and aftercare.

The titanium used in implants is the same biocompatible material used in orthopaedic joint replacements. Allergic reactions to titanium are extremely rare and well-documented when they occur.

Common minor complications

Most patients experience some predictable minor effects after implant placement:

- Swelling and bruising at the surgical site — typically peaks 24–48 hours after surgery and resolves over 7–10 days. - Mild discomfort — usually managed with paracetamol or ibuprofen for the first 2–3 days. Severe pain is unusual and should be reported. - Temporary numbness or altered sensation in the lower lip or chin (lower jaw implants) or cheek (upper) — usually resolves within hours of surgery as the local anaesthetic wears off, but rarely persists for weeks or months in cases of nerve proximity.

These are normal post-surgical effects, not complications in the clinical sense.

Rare but serious risks

The complications that warrant pre-treatment discussion:

1. Nerve injury (lower jaw implants) — the inferior alveolar nerve runs through the lower jaw. CBCT 3D scanning at consultation maps the nerve location precisely and ensures the implant is placed at a safe distance. Permanent altered sensation is rare (<0.5% of well-planned cases). 2. Sinus involvement (upper back implants) — the maxillary sinus floor is often close to the upper molar root sites. CBCT identifies the available bone height. Sinus lift augmentation is performed where indicated to ensure safe placement. 3. Failure to integrate (~1–3%) — the implant does not bond to bone. Diagnosed at the integration check 12–16 weeks after placement. The implant is removed and a replacement placed after a short healing period, at no additional cost to the patient at Tower Dental. 4. Late peri-implantitis — inflammation of the gum and bone around an established implant, usually years after placement, driven by inadequate hygiene and recall. This is the main long-term risk and is preventable with the recall programme included on the Tower Dental adult plan.

How safety is engineered into Tower Dental implant treatment

Five process points reduce the risk profile:

1. CBCT 3D scanning at consultation. Every implant case at Tower Dental includes a CBCT scan to map bone, nerves and adjacent root anatomy in three dimensions. This is the standard of care for planned implant placement and is included in the £40 consultation fee. 2. Surgical guides where indicated. For complex anterior cases or multi-implant rehabilitations, a 3D-printed surgical guide ensures placement is exactly to plan. 3. Strict sterilisation and infection control. Single-use surgical kits, autoclave-sterilised reusable instruments, and CQC-regulated infection-control protocols verified at the most recent inspection (regulations met, May 2024). 4. Resonance frequency analysis at the integration check confirms successful osseointegration before the crown is fitted. 5. Structured aftercare programme includes 12-month, 3-year and 5-year reviews with periapical radiographs to monitor crestal bone levels.

Who should avoid dental implants

Implants are not appropriate for everyone. The main contraindications:

- Active uncontrolled diabetes (HbA1c >8.0%) — wound healing is significantly impaired. - Heavy current smoking — 1.5–2× higher failure rate. Stopping for at least 4 weeks before and 6 weeks after placement substantially improves outcomes. - Recent or active high-dose IV bisphosphonate therapy (most common in cancer patients) — risk of osteonecrosis. - Inadequate bone volume that cannot be successfully augmented — rare with modern grafting techniques. - Patients under 18 — implants are placed only after skeletal growth is complete.

Each of these is identified at the initial clinical examination and CBCT scan. If implants are not the right option, alternatives (bridge, denture, no treatment) are discussed in writing.
