What is a dental implant? A complete encyclopedia of dental implantation
In the modern world of dentistry, no one has to live with missing teeth or loose and slipping removable dentures anymore. Dental implants (Dental Implant) are a revolution that has eliminated the boundary between natural and artificial teeth. But what exactly is an implant and why is it more than just a simple tooth?
An implant is a small screw made of titanium that replaces the root of a lost tooth. After it fuses with the jawbone (Osseointegration), an artificial crown is placed on it that has an appearance and function similar to a natural tooth.
Dental implants are the most advanced and standard method for replacing missing teeth. Unlike older methods (such as removable prostheses or bridges), an implant is the only method that reconstructs not only the crown of the tooth but also the root of the tooth.
Microscopic and Technical Examination of Dental Implant Components
An implant is not simply a “screw”; it is a system of components engineered with micron-level precision that must achieve complete biological compatibility with the living tissues of the body. This system consists of 3 main parts and 2 auxiliary parts:
1.Fixture – Artificial Root
The fixture is the main component that is placed inside the jawbone during surgery.
Material: It is generally made of grade 4 or grade 5 titanium. Titanium is chosen because of its “non‑magnetic” property and its high resistance to corrosion. In recent years, ceramic implants (zirconia) have also been produced for individuals who have metal sensitivity.
Thread Design: The threads on the fixture are designed so that the pressure caused by chewing is distributed across the entire bone surface rather than at a single point, helping prevent bone resorption.
Surface Technology: This is one of the most important aspects in reputable implant brands. The surface of the fixture is roughened using methods such as SLA (sandblasting and acid etching). This microscopic roughness allows bone‑forming cells to attach more quickly and firmly to the implant body.
2.Abutment – Connecting Pillar
The abutment is the component that is screwed onto the fixture after it has fused with the bone and extends above the gum.
Function: Transfers chewing forces from the crown to the fixture and supports the prosthesis.
Types by Angle:
Straight: Used when the implant is placed perfectly vertical.
Angled: When the implant is placed at an angle due to bone limitations, this abutment is used to correct the alignment of the final tooth.
Types by Construction:
Stock: Manufactured in standard sizes.
Custom: Produced using digital scanning and designed specifically according to the patient’s gum shape, providing the best aesthetic outcome.
3.Prosthesis or Crown – Visible Part
This is the part you see in the mouth and use for chewing.
Connection to the Abutment: The crown can be attached to the abutment in two ways:
Screw‑Retained Connection: The dentist screws the crown onto the abutment. Its advantage is that it can be easily removed and repaired in the future.
Cement‑Retained Connection: The crown is cemented onto the base similar to a natural tooth. Aesthetically, it is better for front teeth because there is no screw hole visible.
Auxiliary Parts (Vital During the Treatment Process)
In addition to the permanent components, two temporary but very important parts are used during treatment:
4.Cover Screw – Protective Screw
Immediately after the fixture is placed during the first stage of surgery, this small screw is placed over the opening of the fixture.
Purpose: Prevents blood, gum tissue, and bacteria from entering the internal space of the implant during the 3 to 6 month healing period.
5.Healing Abutment – Gum Former
This component, also called a “gingival former,” is used some time before placing the final tooth.
Purpose: Keeps the gum open in a circular shape around the implant and shapes the soft tissue so that when the final crown is installed, the gum surrounds the tooth in a completely natural way (similar to how a natural tooth emerges from the gum)
The 72‑Hour Critical Rule: Why the First 3 Days Are Decisive
Many patients think that once they leave the clinic, the process is finished. However, the reality is that during the first 72 hours your body is deciding whether to accept or reject the new component (the implant). During this period, a blood clot forms and the first protein fibers responsible for bone regeneration begin their activity.
Below, we examine the five main pillars of this rule in detail:
1.Blood Clot Management (The Blood Clot)
The blood clot that forms at the surgical site acts like a natural sterile pad that protects the underlying bone and provides the foundation for the growth of new cells.
Risk: If this clot becomes dislodged, you may develop a painful condition called “dry socket.”
What to do: Avoid forceful spitting and mouth rinsing for the first 24 hours. Allow saliva to flow gently out from the corner of the mouth.
.2Temperature Control Strategy (Oral Thermodynamics)
During the first 72 hours, the blood vessels around the implant are extremely sensitive.
Absolute prohibition of internal heat: Drinking hot tea, hot coffee, or hot soup causes the blood vessels to dilate and may restart heavy bleeding.
The power of cold: Applying an ice compress (20 minutes on the face, 20 minutes rest) during the first 48 hours constricts blood vessels and minimizes swelling. On the third day (after 72 hours), you may use a warm compress to help reduce possible bruising.
3.The Physics of Chewing and Mechanical Pressure
At this stage, the fixture (implant base) is held in the bone only mechanically and has not yet fused with it.
Smart nutrition: Consume only soft, cool foods that require no chewing (such as yogurt, smoothies, cooled soup, mashed bananas).
Opposite side: Even if other teeth feel normal, never allow food to contact the surgical area.
4.Prohibition of Negative Pressure (Suction)
Creating negative pressure in the mouth is the number one enemy of sutures and blood clots.
No straws: Drinking liquids through a straw creates strong suction that can disturb the surgical site.
No smoking: The act of inhaling from a cigarette, in addition to chemical exposure, creates suction that can increase the risk of implant failure by up to 30% within the first 72 hours.
Sneezing and coughing: If you must sneeze, do so with your mouth open so that pressure is not forced through the surgical site.
5.Swelling Management and Sleeping Position
The peak of swelling and inflammation usually occurs between 48 and 72 hours.
Golden sleep tip: Place two pillows under your head when sleeping. Keeping your head elevated above heart level reduces blood pressure in the jaw area and prevents throbbing at the surgical site and morning swelling

Additional explanations for better understanding of the table:
1.Conventional Implant; Safe and Predictable
This method is best for people who are not in a hurry and want their body to accept the implant with the least stress. In this method, the root is first placed, the gum is sutured, and after a few months—once the root has fully fused with the bone—the crown is installed on it.
2.Immediate Implant; Saying Goodbye to Toothlessness in One Session
This method is mostly used for front teeth that play a role in the smile. On the same day that the surgeon extracts the damaged tooth, the implant base is placed and a temporary crown is installed on it. However, the patient must avoid chewing hard foods with that tooth until the final fusion occurs.
3.Digital Implant; Surgery Without Blade and Sutures
In this method, which is performed with high precision in Dr. Hesam Nazari’s clinic, a CBCT scan of your jaw is first taken. The surgeon determines the exact position of the implant in specialized software, and a plastic guide specific to you is created. The surgery is performed using this guide; therefore, there is no need to cut the gum or place sutures, and the patient can immediately return to normal life.
4.All‑on‑4 Method; A Miracle for Toothless Jaws
If you have lost all the teeth of one jaw, instead of placing 10 or 12 implants, only 4 implants are placed in the jaw at specific angles to support a full fixed set of teeth. This method is a revolutionary solution for people who do not have sufficient bone in the posterior areas of the jaw.
Key Point: The final choice of any of these methods depends on your bone density, budget, and general health condition, which will be determined after a precise examination by Dr. Hesam Nazari

Ideal Candidates for Dental Implant Placement
1.Individuals with sufficient bone density and volume
For stability, an implant requires a “solid foundation.” An ideal candidate is someone whose jawbone has enough thickness and height to accommodate the titanium fixture.
Note: If the bone has resorbed, the person can still be a candidate, but they must first undergo bone graft surgery or sinus lift to reach ideal conditions.
2.Having good general health
Since dental implant placement is considered a surgical procedure, the body must have the ability to repair tissue and bone. Ideal candidates are individuals who:
Are not suffering from advanced autoimmune diseases.
Have diabetes that is fully controlled (stable blood sugar).
Are not undergoing intensive radiotherapy treatments in the head and neck region.
3.Complete gum health
The implant must be surrounded by healthy and strong gum tissue. People who suffer from active gum diseases (periodontitis) must first treat this infection. Healthy gums act like a defensive barrier that prevents bacteria from penetrating the connection between the implant and the bone.
4.Commitment to oral hygiene
An ideal candidate understands that implants require care. Although implants do not develop cavities, their main enemy is bacterial plaque and tartar, which can cause infection around the implant. People who regularly use a toothbrush, dental floss, and a water flosser achieve the best long‑term results.
5.Non‑smokers (or individuals willing to quit)
Smoking reduces blood flow in the gums and severely disrupts the process of bone fusion with the implant. An ideal candidate is someone who does not smoke or at least commits to completely stopping during the sensitive healing period (a few weeks before and after surgery).
6.Individuals who do not suffer from severe teeth grinding
Continuous and involuntary forces caused by bruxism can lead to fracture of the prosthesis or loosening of the implant base. Ideal candidates who have bruxism must commit to using a night guard to protect their investment.
7.Appropriate age (completion of jaw growth)
Implants should not be performed for individuals who are still in their growth stage (usually under 18 years old). As the jaw grows, the implant position remains fixed while other teeth move, which leads to misalignment. An ideal candidate is someone whose skeletal jaw growth has been completed.
Summary: Are you a suitable candidate?
If you have lost one or several teeth, enjoy relatively good general health, and are looking for a solution that functions like a natural tooth for the rest of your life, you are an excellent candidate.
At Dr. Hesam Nazari’s specialized center, your bone condition and oral health are first evaluated using digital scans. Even if you currently do not meet all the above conditions, Dr. Nazari can help turn you into an ideal candidate for a lasting smile by providing appropriate treatment solutions (such as gum or bone reconstruction)
What Exactly Is a Digital Implant?
In the conventional method, the dentist relies on experience and visual observation to cut the gum and determine the implant placement site. But in digital implantology:
1.First, a 3D model of your mouth is created using an intraoral scanner.
2.Specialized radiographic images (CBCT) are combined with the 3D scan.
3.The doctor determines the optimal angle and depth of implant placement in software, precisely according to bone density and the location of the jaw nerves.
4.A surgical guide is fabricated, which acts like a precise ruler placed on the gum and directs the drill exactly to the target point.
Complete Advantages of Digital Implants
1.Flapless Surgery (No Incision or Sutures)
The biggest advantage is that extensive gum cutting is no longer necessary. The implant base is inserted into the jaw through a very small opening (approximately the diameter of the implant itself).
2.Significant Reduction in Pain and Swelling
Because damage to the soft tissues (gums) is minimized, patients experience far less pain, bleeding, and swelling after surgery compared with the conventional method.
3.Exceptional Precision and Safety
The risk of damaging jaw nerves or sinuses is almost zero with this method, because the drill path is predetermined and locked by the surgical software and guide.
4.Very High Speed
Your time in the dental chair is drastically reduced. A surgery that normally takes 45 minutes may be completed in less than 10 to 15 minutes using the digital method.
5.More Aesthetic and Functional Final Result
Because the root position is designed according to the final crown shape, the final tooth will appear more natural and have a better bite alignment.
6.Fast Recovery
The recovery period with this method is very short, and most patients can return to their daily activities immediately.
