Introduction
When your dentist places a dental implant to replace a missing tooth, the depth at which they place it matters more than most patients realize. Placing an implant slightly below the bone level, rather than right at the bone surface, results in better-looking implants that last longer. Understanding why your dentist might recommend subcrestal placement helps you make informed decisions about your implant.
Why Below-Bone Placement Is Better
Your natural teeth have tissues above the bone that help maintain its shape and support the tooth. Learn more about Peri Implantitis Implant Gum for additional guidance. When a dental implant sits right at the bone level, your body needs to create these same tissues around the implant, which causes the bone to resorb (shrink). Bone loss is the main reason implants can look unnatural over time, with the implant becoming visible through the gum or the gum receding away from the implant.
By placing the implant 1-4 millimeters below the bone level, your dentist pre-emptively creates the space your tissues need, eliminating the resorption. This keeps your bone and gums stable and in a better position for a natural-looking result.
Research shows the difference clearly: implants placed at the bone level lose about 1.

Over 5-10 years, this difference is dramatic—the difference between a good-looking implant and one with visible problems.
Combined with Platform Switching
The benefits are even better when subcrestal placement is combined with platform switching (where the crown's connection piece is narrower than the implant itself). Together, these techniques reduce bone loss by about 40-50% compared to implants placed at bone level without platform switching.
This means your implant looks natural not just immediately after placement but continues looking natural for decades.
Planning Your Subcrestal Implant
Successful subcrestal placement requires careful planning:
3D planning. Your dentist uses a 3D scan (CBCT) to visualize your bone, identify the proper implant position, and plan exactly how deep to place the implant. Surgical guides. A custom surgical guide ensures your dentist places the implant at the exact planned depth with precision. This level of accuracy is important for optimal esthetic outcomes. Possible bone shaping. In some cases, your dentist might need to reshape the bone slightly to achieve the ideal position. This is done carefully to maintain adequate bone volume around the implant.Soft Tissue Considerations
The soft tissue (gum) around your implant is just as important as the bone. For the best esthetic results in the front of your mouth, you need adequate gum thickness (at least 1.5-2 mm).
If your gum is thin, your dentist might recommend a soft tissue graft (taking gum tissue from another area of your mouth) done 4-6 weeks before implant placement. This ensures adequate soft tissue thickness to protect the implant and provide a natural appearance.
Custom Abutments for Esthetics
With subcrestal placement, the connection between the implant and crown might be positioned below your gumline. To handle this, custom abutments (instead of prefabricated ones) are often recommended. These are precisely shaped to provide the right emergence profile—the transition from the implant to the crown that mimics a natural tooth.
What to Expect
Timeline. Plan for 4-6 months from implant placement to final crown, though sometimes shorter timelines are possible with excellent bone quality. Temporary crown. A temporary crown guides soft tissue healing during the osseointegration period (when bone bonds to the implant). Adjustments. You'll have several follow-up appointments for adjustments and fine-tuning the final crown.Tips for Long-Term Success
Maintaining good results after dental treatment requires consistent care at home and regular professional check-ups. Brushing twice daily with a fluoride toothpaste and flossing at least once a day forms the foundation of good oral hygiene. These simple habits go a long way toward protecting your investment in your dental health and preventing future problems.
Your dentist may recommend additional steps specific to your situation, such as using a special rinse, wearing a nightguard, or adjusting your diet. Following these personalized recommendations can make a significant difference in how well your results hold up over time. Scheduling regular dental visits allows your dentist to catch any developing issues early, when they are easiest and least expensive to address.
When to Talk to Your Dentist
If you have any concerns about subcrestal implant placement below bone level, bringing them up at your next dental appointment is always a good idea. Your dentist has the training and experience to evaluate your situation and recommend the most appropriate course of action. Even concerns that seem minor can sometimes indicate an underlying issue that benefits from early attention.
Many patients find it helpful to write down their questions before an appointment. This ensures you don't forget anything important during your visit. Your dentist appreciates when you take an active role in your oral health, and open communication helps build a strong partnership between you and your dental care team. Remember that no question is too small or too simple to ask.
Pay attention to any changes in your mouth between dental visits. If you notice new symptoms like persistent pain, swelling, bleeding, or sensitivity, don't wait for your scheduled appointment. Contact your dental office to describe what you are experiencing, and they can advise whether you need to come in sooner.
Prevention and Daily Care
One of the best ways to protect your dental health is through consistent daily care. Brushing your teeth at least twice a day with fluoride toothpaste removes plaque and bacteria that can lead to decay and gum disease. Using a soft-bristled toothbrush and gentle circular motions helps clean your teeth effectively without damaging your enamel or irritating your gums.
Flossing once daily reaches the areas between your teeth that your toothbrush cannot access. These tight spaces are common spots where food particles and plaque collect, so regular flossing plays an important role in preventing cavities and gum problems. If traditional floss is difficult to use, ask your dentist about alternatives like water flossers or interdental brushes.
Your diet also has a significant impact on your oral health. Limiting sugary snacks and acidic beverages helps protect your tooth enamel from erosion. Drinking plenty of water throughout the day rinses away food particles and keeps your mouth hydrated. Crunchy fruits and vegetables like apples, carrots, and celery can help clean your teeth naturally between brushings.
Every patient's situation is unique. Talk to your dentist about the best approach for your specific needs.Conclusion
Subcrestal implant placement, often combined with platform switching and soft tissue optimization, provides superior esthetic and functional outcomes. While it requires more careful planning, the long-term benefits—better bone preservation, healthier soft tissues, and more natural appearance—make it the standard of care for esthetic implant cases.
> Key Takeaway: Placing your implant slightly below the bone level preserves bone and gums, resulting in an implant that looks natural and lasts longer than implants placed at bone level.
