There are very few absolute contraindications, among which we can highlight serious diseases that affect bone metabolism, specific infections, malignant tumors affecting the bone, or high-dose radiotherapy.
It is important to note that dental implants do not cause rejection by the body. When rejection is commonly discussed, it usually refers to the failure of the dental implant to osseointegrate (a failure rate of 2% to 5% of implants placed is considered normal). When a dental implant fails to osseointegrate, another can be placed to replace it.

This is an outpatient procedure, meaning the patient is treated at our dental clinic.
The procedure is performed in most cases under local anesthesia. For longer procedures (full mouth rehabilitation, sinus lifts, bone regeneration), intravenous sedation administered by an anesthesiologist at the dental clinic may be used.

Contrary to what it may seem, in many cases the post-operative period involves less discomfort than other minor dental procedures. An implant can sometimes cause gum discomfort during the wound healing process, so analgesics or anti-inflammatories are prescribed depending on the type of procedure.
Maintaining good oral hygiene during this period is essential to prevent gum infections. Antibiotics are usually prescribed as a precaution. In some cases, swelling frequently appears during the first few days, which usually subsides spontaneously within 72 hours. It is not painful and allows for normal daily activities.

The prostheses can be placed after a three- to six-month waiting period once the surgery has been performed.

Implants can be placed in young people once development is complete, usually from the age of sixteen in women and eighteen in men. There is no age-related contraindication for adults.

There are basically two types of implant-supported prosthetic rehabilitation: fixed prostheses made of zirconia or porcelain-fused-to-metal, which offer the highest level of aesthetics, comfort, and function, and removable prostheses (which can be taken out and put back in), made of resin. Removable prostheses are a more economical option as they are a less sophisticated treatment (since there are no teeth) and require more maintenance. In the clinic, the dentist takes impressions and bite registrations, which are then sent to the laboratory. There, the dental technician pours the impressions into plaster and fabricates the structures of the fixed prosthesis using wax models. These wax-ups are then embedded in special high-temperature resistant investment materials, and the metal is cast using various alloys.
The final step could be mounting the ceramic onto the metal structures, depending on the type of fixed prosthesis to be made, since there is also the possibility of making the crowns and bridges in pure porcelain (without metal) or on a base of a white material called alumina or zirconium, in the latter case the innovative cadcam technology is used.

Properly placed implants guarantee aesthetic results that, in most cases, are far superior to the patient's original teeth.
The patient should understand that they will not only achieve a healthy mouth but also an aesthetically pleasing smile. These should be their expectations.

Well-placed implants of a size proportional to the load they have to bear (the larger the size, the greater the safety) are for life.

The fundamental conditions for ensuring success are:
1. Proper planning of the specific case
2. The surgeon's skill and experience (implant size and correct placement)
3. The fabrication of the prosthesis, taking into account the loads it must bear and ensuring a proper fit to avoid abnormal forces that could overstress the implants

Quizás el riesgo más significativo es la pérdida de sensibilidad en la zona del labio inferior cuando durante la intervención se toca o se secciona el nervio mentoniano, dicha pérdida de sensibilidad puede ser temporal o permanente.
For this reason, one must be especially careful when operating in that area because it is not good to touch the nerve with an implant that is too long, but neither is it good to have an implant that is too short and cannot withstand the load it will be subjected to.
On the other hand, it is essential that the implants are correctly placed from the beginning, since once they osseointegrate they become "fused" to the bone and if it were necessary to remove them we would lose a lot of maxillary bone, which would greatly complicate rehabilitation and of course the results would never be the same.

Today, we have advanced techniques for performing surgery in extreme cases. We can resort to maxillary sinus lifts and grafts, which can be autologous (from the patient's own body) or of other types, with a very high success rate.
Fortunately, it is extremely rare for a patient who wishes to be rehabilitated to be unable to do so. The field of bone regeneration is undoubtedly one of the most significant advances in implantology in recent years.

For patients with periodontitis, implants are "THE SOLUTION." Traditionally, these patients were inevitably destined to lose their teeth.
The only treatment we could offer them was meticulous hygiene and regular visits to the clinic for periodontal treatments. The end result was always the same: a complete removable denture.
Now, implants have revolutionized the way we treat these patients. It's crucial to understand that lengthy periodontal treatments are not only useless but harmful because while we strive to preserve the natural tooth, we can't prevent the disease from progressing and causing bone loss. We must stop this process before it's too late.
Bone is fundamental for a successful rehabilitation and an aesthetic outcome. In extreme cases, achieving an aesthetic result is very difficult.

This may be the only case in medicine where the artificial replacement functions better than the original organ.
An implant that works correctly in the mouth (because it is placed in the ideal position and supports an axial load proportional to its size) has a lifespan far exceeding that of a natural tooth.

When we talk about implants without surgery, we're referring to computer-guided, blind surgical procedures. All these systems use a pre-made template onto which the implants are fitted, allowing us to place them without having to open the gum or use sutures. Logically, the procedure is less invasive, but even a slight variation in the template's position in the mouth could cause problems.

It is only advisable to do so in very specific and favorable cases. Even then, the quality of the prosthesis that can be offered in these cases is greatly affected by the time factor. In these cases, we offer temporary resin teeth that will later be replaced by permanent, highly aesthetic ceramic prostheses. Ceramic treatments cannot be completed in a single day; it is only possible to create pre-designed, and therefore not personalized, resin prostheses.

Those we discussed in the previous question, in which the prosthesis is placed on the same day as the surgery.

Zirconium is an excellent material in dentistry, boasting maximum biocompatibility (the same as titanium) and allowing for prostheses with unsurpassed aesthetics. However, its use in dental surgery is recent and still very limited. It can be said that as an implant, that is, placed within the bone, it offers no added advantages over titanium. It is a choice made by the dentist.
