I Causes and Consequences of Missing Teeth

There are many causes of tooth loss, such as cavities, dental trauma, and periodontal disease. These factors progressively damage the teeth and surrounding periodontal tissues, causing teeth to loosen and eventually fall out. Missing teeth not only affect aesthetics and oral function but also have a negative impact on overall oral health. After losing a tooth, the alignment of the remaining teeth becomes unbalanced, potentially causing neighboring teeth to shift, alveolar bone atrophy, and surrounding soft tissue shrinkage, further affecting facial structure and even giving an aged appearance. Therefore, understanding the causes and consequences of missing teeth helps emphasize the importance of early prevention and timely treatment.

II Main Impacts of Missing Teeth

1. Affecting Oral Structure

After tooth loss, adjacent teeth tend to tilt into the gap left by the missing tooth, forming spaces that lead to food impaction. Over time, this misalignment can disrupt the entire dental arch, affecting normal occlusion. The remaining teeth may gradually loosen or even fall out due to bearing excessive bite force.

2. Causing Jaw Joint Problems

Tooth loss can restrict the forward, backward, and lateral movement of the mandible, resulting in air leakage while speaking, unclear pronunciation, and, in severe cases, temporomandibular joint disorder (TMJ), which can cause joint pain, limited mouth opening, and impair daily life quality.

3. Impacting the Digestive System

Missing teeth can affect chewing efficiency, making it difficult to thoroughly grind food and impacting digestive efficiency. This increases the burden on the gastrointestinal tract, potentially causing stomach and intestinal issues that negatively affect overall health.

For this reason, missing teeth should be treated promptly. Dental implants have become an increasingly popular and effective restorative option.

III What Are Dental Implants?

Dental implants, also known as artificial teeth implants, do not involve directly "planting" natural teeth. Instead, they use a highly biocompatible material (implant) to insert an artificial tooth root into the alveolar bone, on which an artificial tooth is then installed. The implant forms a strong bond with the alveolar bone, supporting and securing the dental crown to provide functionality and aesthetics similar to natural teeth.

A dental implant consists of three parts: the implant, abutment, and crown. Once the implant is integrated with the alveolar bone, the crown is fixed onto the implant through the abutment, creating a complete restoration. Dental implants do not require grinding down adjacent teeth, offer strong chewing function, and appear natural, earning them the name "third set of teeth." Implants and abutments are often made of titanium, which has excellent biocompatibility with the human body and does not interfere with MRI scans, making it a highly regarded option in restorative dentistry.

IV Main Stages of Dental Implant Treatment

The process of getting dental implants usually consists of the following stages:

1. Pre-surgical Oral and Routine Examinations

Before treatment, a detailed oral examination, including a dental CT scan (CBCT), provides information on the quality and density of the alveolar bone and determines whether a bone graft is needed. If the patient's alveolar bone conditions are favorable, implant surgery can proceed directly; if not, a bone graft surgery may be required to increase bone volume. Additionally, health indicators such as blood pressure and blood sugar are checked to ensure the patient is in good physical condition for the procedure.

2. Implant Placement

A hole is pre-drilled into the alveolar bone, and the implant is inserted, after which the gums are sutured. Following implant placement, a 3-6 month osseointegration period is required, during which the implant firmly integrates with the alveolar bone.

3. Healing Abutment Installation

After confirming a successful osseointegration via X-ray, the second-stage surgery is performed to install a healing abutment. This component helps the gums heal around the implant, creating optimal soft tissue conditions for the final crown placement.

4. Mold Taking and Crown Installation

Once the gums have healed, the dentist takes an impression to create the crown. The fabrication process usually takes 2-3 weeks, after which the crown is attached to the permanent abutment, completing the entire dental implant restoration.

V Different Types of Dental Implants

With advancements in dental technology, implant procedures have been refined to meet diverse patient needs. Here are some of the main types of dental implants:

1. Single-Tooth Implants

Designed for the loss of a single tooth, this procedure involves placing an independent implant in the missing area without impacting neighboring teeth.

2. Multiple-Tooth Implants

For multiple consecutive missing teeth, multiple implants can be used for restoration without relying on traditional bridge methods.

3. Full-Arch Implants

For patients with total edentulism (missing all teeth), full-arch restoration can be achieved with 4-6 implants supporting a complete set of teeth, such as the "All-on-4" immediate loading technique, significantly improving quality of life.

4. Immediate Implants

This technique allows certain patients to undergo implant restoration immediately after tooth extraction, saving time. However, it has strict requirements regarding the alveolar bone condition and is not suitable for all patients.

VI Advantages of Dental Implants

Dental implants offer the following benefits, making them an ideal restoration choice:

1. Bone Preservation

Implants stimulate the alveolar bone, preventing bone resorption and atrophy, thus preserving facial contours.

2. High Aesthetic Quality

Implants closely mimic the look and feel of natural teeth, making them difficult to distinguish from real teeth, with an excellent aesthetic appearance.

3. Chewing Efficiency

Compared to traditional dentures, implants have stronger chewing power, making eating more convenient and comfortable.

4. Preserves Adjacent Teeth

Unlike traditional dental bridges, implants do not require grinding down healthy neighboring teeth, avoiding any damage to other teeth.

5. Long-lasting

With proper daily maintenance, dental implants typically last over ten years, offering long-term functionality.

VII Future Development Trends in Dental Implants

As a frontier in dentistry, dental implants provide more options for patients with missing teeth. With continuous technological advancement, implant techniques are becoming more refined, and new materials and methods are increasingly applied in clinical practice. In the future, dental implants will become more personalized and comfortable, catering to the needs of a wider range of patients.
