Indications for Dental Implant: Who Can Get It & Who Should Absolutely Avoid It?

Indications for Dental Implant: Who Can Get It & Who Should Absolutely Avoid It?

Prolonged tooth loss not only causes difficulty in chewing, misaligns the bite, but also leads to jawbone resorption and premature facial aging. Dental implants are currently the most comprehensive method to restore lost teeth from root to crown. However, this is a specialized dental technique that requires strict health standards. Understanding the indications for dental implants as well as contraindications will help you choose the safest and most successful treatment plan.

1. When do doctors recommend dental implants?

Unlike dental bridges that require grinding down natural teeth or removable dentures that can be loose, implants function as independent roots integrated directly into the jawbone. Doctors will recommend dental implants for the following clinical cases:

• Loss of a single tooth anywhere on the arch: Whether it's a front tooth requiring high aesthetics or a molar responsible for main chewing force, when a tooth is lost due to accident or disease, performing single tooth implant will help completely recreate a new independent tooth, preserve the integrity of the two adjacent natural teeth, and promptly prevent jawbone resorption in the missing tooth area.

• Loss of two or more teeth (adjacent or spaced apart): When multiple teeth are lost on the arch, chewing force is significantly reduced and the remaining teeth tend to tilt into the gap. With the solution of multiple tooth implants, the doctor will calculate the optimal number of implant posts combined with a supporting dental bridge above. This method not only fully restores firm chewing ability but also saves costs as it does not require one post for each missing tooth.

• Complete loss of teeth in one or both jaws: For older adults or those who have lost all teeth and do not want to endure the inconvenience, slippage, or gum pain from traditional removable dentures, the doctor will recommend full arch dental implants using advanced techniques like All-on-4 or All-on-6. With only 4 to 6 implant posts placed at the best bone positions, a full set of 12 – 14 new teeth will be securely supported, restoring over 90% of natural chewing power and supporting a youthful facial structure.

• Severely damaged teeth that cannot be preserved: Teeth that are decayed and broken down to the root near the gum, periodontitis at stages 3-4 with severe looseness, or severe root tip infections that require extraction. If the bone tissue is still good, the doctor may recommend immediate implant placement during the same minor surgery to shorten the waiting time.

2. Completion process after implant placement: Restoring porcelain teeth on implants

A complete dental implant procedure does not stop at placing the Titanium post into the jawbone. After a period of 6 weeks to 6 months (depending on the individual's condition and the type of post) for the post to integrate firmly with the bone, the client will enter the stage of restoring porcelain teeth on implants.

In this step, the doctor will attach the Abutment connector and fix the porcelain crown (or bridge/denture) crafted precisely according to personalized dental impressions onto the implant post. The restoration phase directly determines:

1. Natural aesthetics: The shape, color, and translucency of the porcelain crown blend perfectly with the natural teeth on the arch.

2. Bite balance: Ensures even distribution of chewing force, avoiding discomfort or overloading the implant post below.

3. Long-lasting durability: Perfectly snug with the gum line, preventing food from getting stuck and causing peri-implantitis.

3. Essential conditions to meet implant placement indications

To ensure the implant placement surgery proceeds smoothly and the implant integrates quickly with the bone, clients need to meet 4 core conditions:

4. Contraindications for dental implants to note

Besides the indications for dental implants, doctors also clearly classify 2 groups of contraindications to ensure absolute safety for clients:

4.1. Absolute contraindications (Do not perform implants)

• Children and adolescents under 18: The jawbone is still developing, early placement of fixed posts can deform the arch or bury the post.

• Pregnant women: The process of taking CT Cone Beam 3D X-rays, using anesthesia, antibiotics, and stress during minor surgery can adversely affect the fetus.

• Severe uncontrolled systemic diseases: People with severe diabetes who cannot control blood sugar (wounds heal very slowly and are prone to infection), heart failure, end-stage kidney failure, leukemia, severe coagulation disorders, or those who have recently undergone radiation therapy in the maxillofacial area.

• Individuals with behavioral control issues: Suffering from severe mental disorders, unable to cooperate with the doctor throughout the surgery and postoperative care process.

4.2. Relative contraindications (Pre-surgical treatment required before implantation)

• Heavy smokers: Smoking constricts blood vessels, reduces blood supply to bone and gum tissue, significantly increasing the risk of implant rejection compared to non-smokers. Clients must quit smoking at least 2 – 4 weeks before and after implantation.

• Severe jawbone resorption, low sinus floor: Due to prolonged tooth loss. In this case, implants can still be placed but require sinus lift procedures and additional bone grafting.

• Habit of teeth grinding during sleep: The unconscious grinding force is very strong and can break the connecting screw or chip the porcelain. Clients need to wear a specialized anti-grinding splint after completing the restoration.

Determining whether a client falls under the indications for dental implants cannot be done by mere visual inspection. At Santé Dental Clinic, every client before getting implants undergoes an examination following international standards:
