Dental Implants

Dental implants are artificial roots made of titanium or zirconium that are surgically placed into the jawbone to replace missing teeth. Implants integrate with the jawbone through the osseointegration process, forming a solid foundation and mimicking the appearance and function of natural teeth. In addition to improving chewing function, they offer advantages such as preventing bone loss and stabilizing adjacent teeth. The healing process can vary from person to person, and in some cases, additional procedures like bone grafts may be necessary. Regular oral hygiene and dental check-ups are crucial for long-term success and reducing the risk of infection.

What is a Dental Implant?

A dental implant is a device made of titanium that is surgically placed into the jawbone and serves as an artificial root to replace missing teeth. This titanium screw integrates with the jawbone, forming a solid foundation, and functions like a natural tooth root through a process called osseointegration. The modern use of dental implants began in 1952 when Dr. Per-Ingvar Brånemark discovered titanium’s ability to integrate with bone. Since the 1960s, this application has become widespread, its reliability increased with FDA approval, and it has become a standard in treatment procedures. Today, dental implants not only improve chewing and speaking functions but also provide an aesthetic appearance, offering a permanent solution for missing teeth.

How Do Dental Implants Work?

The working principle of dental implants relies on the implant integrating with the jawbone to provide long-term support. This integration process is called “osseointegration,” where the implant merges with the surrounding bone to form a load-bearing structure. During osseointegration, a direct interface is formed between the implant surface and the bone, allowing the implant to take over the functions of a natural tooth.

After the implant is placed, the body initiates a multi-stage healing process at the bone-implant interface:

• Blood clot
• Granulation tissue
• Osteoprogenitor cells

During these stages, osteoprogenitor cells transform into osteoblast cells that form bone matrix on the implant surface. These cells ensure the implant binds to the bone, while the remodeling and maturation process continues for months, creating an implant that is integrated into the jawbone.

The surface characteristics of the implant affect osseointegration. Implants with rough and micro-porous surfaces facilitate bone cell attachment, providing higher stability. Therefore, bioactive coatings such as hydroxyapatite can support cellular bonding and bone formation on the surface.

Finally, the implant-abutment connection is crucial for stability and longevity. A strong connection minimizes micro-movements to prevent issues like peri-implantitis and the soft tissue seal prevents bacterial infiltration, reducing inflammation. These elements play a key role in the long-term success of the implant.

When Are Dental Implants Used?

Dental implants are used in various cases of tooth loss to meet both aesthetic and functional needs. They provide a fixed solution for the loss of one or more teeth, offering a natural-looking and functional appearance similar to natural teeth. The situations in which dental implants are used are as follows:

• For one or more missing teeth
• In edentulous upper or lower jaws
• To support removable dentures
• In situations requiring immediate or delayed loading
• With specialized implant techniques in cases of bone loss or atrophic jaws

Implants offer a safe alternative by enhancing the quality of life for patients who wish to avoid removable dentures or have difficulties with dentures. For instance, implant-supported solutions like “All-on-4” used in full edentulism are suitable for patients with sufficient bone density and provide more stability compared to traditional dentures. Methods supported by specialized techniques, such as zygomatic implants for patients with bone loss, offer a solution that does not require bone grafts.

Patients undergoing implant placement are evaluated based on jawbone quality, overall health status, and functional needs. In this process, imaging techniques such as cone beam computed tomography (CBCT) help determine the most suitable implant placement.

Who is Orthodontic Treatment Not Suitable For?

While dental implants generally have high success rates, they may not be suitable for every individual due to certain health and lifestyle factors. In particular, implant placement may be contraindicated for individuals with chronic diseases that negatively affect the healing process or those who have difficulty maintaining healthy bone structure.

Systemic Health Conditions:

• Uncontrolled diabetes
• Cardiovascular diseases
• Autoimmune diseases
• Osteoporosis
• Use of bisphosphonates

Oral Health and Structural Factors:

• Insufficient bone density
• Active periodontal disease
• Untreated cavities
• Smoking

Lifestyle and Behavioral Factors:

• Excessive smoking
• Chronic alcohol use
• Poor oral hygiene
• Bruxism (teeth grinding)

When evaluating candidates for dental implants, both systemic health conditions and oral health must be thoroughly assessed. For example, in individuals who smoke, reduced blood circulation to the gums can negatively affect the healing process. Similarly, habits that exert pressure on the jaw and teeth, such as bruxism, can have adverse effects on the stability and lifespan of implants.

How Are Dental Implants Placed?

Dental implants offer a durable solution to replace missing teeth. The implant procedure consists of several stages, and various steps are carefully carried out throughout the process. The success of the treatment process relies heavily on the patient’s bone health and healing rate at each stage.

• Initial Evaluation
• Bone Graft (If Necessary)
• Implant Placement
• Healing Process (Osseointegration)
• Abutment Placement
• Final Crown or Prosthesis Attachment

Each stage aims to ensure that the implant is firmly placed in the jawbone and to form a functional dental structure. In the initial evaluation stage, the dentist examines the jawbone and uses X-rays or 3D imaging techniques to plan the treatment. If there is insufficiency in the jawbone, a bone graft may be recommended. After implant placement, the healing process begins, and bone tissue grows around the implant to complete the osseointegration process. Osseointegr

ation ensures the integration of the implant with the jawbone, providing a long-lasting result.

In the final stage of the dental implant, an abutment is placed, and a prosthesis or crown specifically manufactured to match natural teeth is attached. This final step allows the patient to comfortably chew and speak in daily life.

What are the Side Effects of Dental Implants?

Dental implant procedures may include some surgical infectious and mechanical complications. These complications can vary depending on the patient’s overall health, oral hygiene habits, and the surgical technique used.

• Surgical Complications: Sinus perforation
• Nerve Damage: Numbness in lips, gums, and jaw
• Infections: Development of peri-implantitis
• Mechanical Problems: Screw loosening and breakage
• Bone Loss: Insufficient osseointegration
• Systemic Reactions: Chronic pain and swelling
• Allergic Reactions: Itching due to metal sensitivity
• Hygiene Challenges: Risk of plaque buildup and inflammation

Surgical complications such as sinus perforations are particularly observed in upper jaw implants, while nerve damage can cause permanent or temporary numbness and tingling in the lips and jaw. Post-implant placement care is important for both the health of the tissues surrounding the implant and the long-term success of the implant. Inadequate oral hygiene can trigger peri-implant diseases and increase the risk of infections. Excessive strain on implant components can compromise the stability of the implant, necessitating frequent check-ups and, if necessary, the re-adjustment of the implant structure.

How Successful are Dental Implants?

The success rate of dental implants is generally high, and they can function healthily for many years. Various factors directly affect the success rate by ensuring implants are long-lasting and functional. Studies have shown that the survival rates of dental implants are over 90%, and this rate can be even higher under suitable conditions.

Factors Affecting Success:

• Good oral hygiene
• Regular dental check-ups
• Implant surface treatments
• Patient-specific factors
• The area where the implant is used
• Minimally invasive techniques

Factors affecting the success rate of implants include bone health and the surface technologies used. Particularly, applying bioactive surfaces increases osseointegration and ensures long-term stability. These surface treatments enhance the bone’s ability to adhere to the implant, thus speeding up the initial healing process and reducing possible complications. Additionally, implants used for small bridges or single crowns have higher success rates compared to implants supporting larger prostheses.

Despite high success rates, some complications may occur. Peri-implantitis and marginal bone loss are among the commonly observed risks. Marginal bone loss remains minimal within the first year after placement and can vary between 0 to 0.2 mm annually in subsequent years.

How Should Care be Done After Dental Implants?

Post-dental implant care is crucial to extend the lifespan of the implant and preserve the health of surrounding tissues. The elements to be attended to in this process include daily care steps performed by the patient and regular professional check-ups. Home oral hygiene minimizes plaque accumulation around the implant area, reducing the risk of complications.

Home Care Recommendations:

• Using a soft-bristled toothbrush
• Using dental floss or interdental brushes without metal
• Supportive use of antimicrobial mouthwashes

Professional Care: Professional cleanings performed by dentists periodically are especially important for removing subgingival plaque accumulation. The use of non-abrasive tools containing plastic or carbon fiber minimizes the risk of damaging implant surfaces. Special ultrasonic tips can also be safely used if necessary.

Monitoring Complications: Peri-implant health should be evaluated through routine check-ups. Signs of inflammation such as bleeding on probing, probing depths, and recession can indicate the development of implant mucositis or peri-implantitis. These conditions can signal advanced level complications that require treatment.
