Historically, dental implants have been widely performed in Korea since the late 1990s, while modern implant surgery has been conducted worldwide since the 1960s, providing sufficient clinical evidence. Both in Korea and globally, implant surgery is recognized for its high success rate, providing chewing power similar to natural teeth and aesthetic results. In the past, the main concern was how to ensure successful osseointegration of implants. Nowadays, with implant success generally assured, the focus has shifted to how quickly implants can be securely fixed into the jawbone, proving the procedure to be a consistently stable dental treatment.

Compared to dentures or conventional prosthetics, implants recreate the feeling of natural teeth, providing psychological comfort and confidence in social interactions.
1. Implants generally last longer than traditional prosthetics. Implants integrated into the jawbone can last around 7 years or even permanently, while the prosthetic on top of the implant usually lasts about 8 years.
2. Adjacent teeth do not need to be shaved down or damaged, unlike traditional bridges.
3. Implants provide chewing force 5–7 times stronger than dentures or conventional prosthetics.
4. Implant prosthetics allow chewing like natural teeth.
5. Implants help maintain healthy jawbone and gums, unlike long-term dentures which may cause bone loss.
6. No discomfort from removable dentures.
7. Food taste is better than with dentures.
8. Implants do not cover the palate or gums, reducing foreign body sensation.

Implants are made of titanium. Titanium forms a stable oxide layer on its surface, so it does not rust. This is why it is widely used in orthopedics, general surgery, and plastic surgery. Titanium can appear on X-rays but does not trigger metal detectors. In MRI scans, it may slightly obscure adjacent areas, but otherwise, it poses no known problems for the human body.

Some patients worry about metal allergies affecting surgery. There are no documented cases of implant failure due to metal allergy. In precaution, implants and surface treatments can be selected individually to accommodate patients’ physical conditions, allowing surgery for nearly everyone.

Other prosthetic treatments like crowns, bridges, and dentures can also restore missing teeth. However, implants are functionally superior and increasingly popular. Treatment choice should consider cost, time, and patient preference.

The basic principle is to place implants according to the number of missing tooth roots. However, adjustments may be made based on jawbone condition or financial considerations. Consultation with a dental specialist is necessary.

“1-Day Implants” or “rapid implants” refer to completing the implant placement and prosthetic preparation in one day, instead of the traditional two-step process. Not everyone is eligible. Candidates must have sufficient bone volume, dense bone, and healthy gums, with treatment carried out by experienced specialists. The total number of hospital visits is usually around 3–4 times, although the complete bone integration process may take several months depending on individual bone conditions.

Immediate implant placement is possible, but only if there is sufficient bone volume and density. Precise diagnosis and evaluation by an experienced clinician are essential for this procedure.

When upper molars are missing, the sinus cavity above the jawbone can descend, leaving insufficient bone for implants. A sinus lift involves raising the sinus floor and placing bone graft material to create enough bone for implants. This enables implants even in patients with thin upper jawbone in the molar area.

Implants may be difficult in certain conditions. For example:
Patients with uncontrolled diabetes, hypertension, or heart disease may have slower bone integration.
Insufficient space between teeth may require preparatory treatment.
Lack of bone in the lower jaw or near the sinus in the upper jaw may require bone grafting or sinus lift surgery. Consultation with a specialist is necessary for proper treatment planning.

Some swelling or mild pain may occur, but modern techniques and anesthesia minimize discomfort. Postoperative pain can be managed with prescribed medication, and in some cases, patients report less pain than tooth extraction.

Shape and materials are similar, and the 5-year success rates are comparable. Imported products may have longer-term data (e.g., Branemark System with 40-year follow-up) and may be slightly more expensive. Domestic implants increasingly match the performance of imported ones. The choice should focus on suitability for the surgical site and implant features rather than origin.

Implants can be performed regardless of the number of missing teeth. Even if wearing full dentures, implant treatment is possible. Hybrid “implant-supported dentures” are also available.

Implants can be placed after jaw growth is complete, typically after age 17. Patients with systemic conditions should exercise caution. Reports show successful surgeries even for patients over 80. The focus should be on overall health rather than age, with proper evaluation and treatment planning.

Alcohol and smoking increase the risk of postoperative inflammation. Nicotine delays gum healing. Avoiding alcohol for 2–3 weeks is recommended, while smoking cessation is critical for implant success. Maintaining oral hygiene and regular check-ups are essential for long-term implant health.

Implant longevity varies with oral hygiene and care. With proper hygiene, regular check-ups, and lifestyle considerations, implants can last 8–20 years or more. However, poor oral care or inflammation can shorten lifespan. Regular maintenance and choosing a specialized implant clinic are key for long-term success.

Minor swelling, inflammation, or temporary numbness may occur but usually resolves naturally. Individual conditions are considered, and appropriate measures are taken to minimize complications. Accurate pre-surgical diagnostics and careful procedures are performed.

Surgery usually takes 1–2 hours, depending on the number and location of teeth. After placement, osseointegration takes about 6 months for the upper jaw and 3 months for the lower jaw before prosthetics are attached. If gum inflammation or bone deficiency exists, preliminary treatment may extend the timeline. Regular check-ups every 3–6 months during the first year are crucial for monitoring success.

Implants can fail, usually due to poor maintenance or excessive forces rather than material defects. Signs include pain, mobility, or gum swelling. Early removal allows bone to regenerate and subsequent re-implantation or conventional prosthetics. Regular dental check-ups help prevent and address failures. Studies show about 88% of implants last over 10 years. Initial failures can be retreated, often at 50% of original surgery cost (minimum consumer protection guideline).

Implant surgery is globally widespread. In Korea, based on 40+ years of clinical data and material advances, success rates exceed 90% when proper conditions are met. Success is divided into “treatment completion” (implant placement with prosthetic attachment) and “maintenance” stages, with the completion stage success rate nearing 90% under optimal conditions.
