Dental Implants for Molars


Many people at some point in their life lose a tooth or their dentist tells them that they will have to have an implant placed in a tooth. In fact, the placement of implants in molars is very common since these are the teeth that are most frequently lost.

The reason that molars are lost so often is that both cavities and periodontal disease are especially primed with these types of teeth and that is why they are the ones we implantologists treat most often.


In general, the replacement of a molar by an implant is a simple treatment. Here are the steps to place an implant in molars and some circumstances that make treatment difficult.

 Usual protocol when implants are placed in the molar area

STEP 1: Removal of the molar

Because molars are teeth with more than one root, when they are extracted, the “hole” that remains in the bone has a considerable dimension.

This factor, which seems irrelevant, is in fact very important since it almost always prevents the placement of the implant on the same day that the tooth is removed.

Except in very exceptional situations, in which the implant can be placed in the space between the roots, the normal thing is to do the extraction of the tooth first and two or three months later to place the implant.

Obviously, there are those who will want to replace a tooth faster, but from our point of view, the molar is a tooth that allows to work respecting biological times since aesthetically it is not taught and its absence does not prevent a relatively normal life for a while.

STEP 2: CT scan to identify implant thickness and height

After two or three months, a CT scan of the area to be treated will be performed to identify the thickness and height of the implant and the need or not for additional treatments such as bone or soft tissue grafts.

STEP 3: Placing the crown

Once the implant has been placed, you should wait between 6 and 12 weeks to start the prosthetic treatment that will culminate in the placement of the crown or tooth in the desired location.

SURGERY: What is surgery for the placement of implants in molars?


Many people ask us how is surgery on tooth implants and now we will tell you the steps before and after placing an implant.

Once the type of implant has been selected and the need or not for additional treatments, the patient will attend the surgical visit.

  • Previous considerations: The first thing to keep in mind is that it is not necessary to come on an empty stomach or prepare in any specific way for this type of approach.
  • Protection and anesthesia : Once the patient enters the surgery room, a sterile protector will be placed over the body and eyes so that the surgeon will only see the patient’s mouth and will proceed to anesthetize the patient with local anesthesia.
  • Separate gum from bone: A flap will then be made in order to separate the gum from the bone and thus see its dimensions.
  • Bone milling: The next step is milling the bone with increasingly wide diameter drills until the desired diameter is reached depending on the selected implant.
  • Implant placement: Finally, the implant is placed in the bone and a healing plug is screwed over it, which will have the function of covering the head of the implant and shaping the gum for the future crown.
  • Suture with stitches: It is sutured with non-absorbable stitches (normally) and the case is already closed.

POST-TREATMENT: What happens after surgery?

During the post-treatment, which is generally not bothersome, the patient will take oral antibiotics and some type of analgesic and anti-inflammatory.

After a week or 10 days, the stitches will be removed and the patient will rest until after 6-12 weeks the prosthetic treatment begins.

The type of dental implant for molars used is one of the key elements in reducing the risk of complications.

Working with high-end implants like Straumann is undoubtedly a guarantee of quality for the patient due to the high degree of sophistication and scientific studies behind this implant system.

In fact, many patients ask us about the cost of dental implants and it depends on many factors, but in general the type of implants, the quality of the materials and the dentist’s service are of vital importance.

What factors complicate the placement of implants in molars?

The main complication in this type of surgery is the absence of bone in the area where the implant is to be placed.

There are 3 fundamental reasons that lead to bone limitation when placing an implant in molars:

  • Anatomical factors: having very large maxillary sinuses or having a mental nerve that runs very high are two of the main anatomical limitations faced by the surgeon. that is why it is essential to perform a CT scan before carrying out the surgery.
  • Infections: In case of infections that cause injuries to the root of the tooth, it is best to proceed with the extraction and wait to see how the bone heals. If after 2 months, when performing the CT, a limitation of height to the sinus or teeth is observed, then extra-short implants must be regenerated or placed.
  • Periodontal disease : If the patient suffers from periodontal disease , it is common that there is not enough bone and in these cases it is more common to have to regenerate before or during implant placement.

If you feel that you may suffer from any of the above cases, you can request a free first visit on dental implants at our clinic in Barcelona without obligation and we will help you get out of your doubts.


The prosthetic treatment is carried out over 3 or 4 visits approximately 15 days apart from each other.

During this phase the objective is to create a ceramic crown with a metal body together with the prosthetic laboratory.

Fig: In the image on the left we see the appearance of the metallic body of the implant crown when its adaptation to the tissues is verified. On the right we can see the crown finished with the ceramic coating.

Currently, this process is carried out in a digitized way so that the adaptation between the crown and the implant is optimal and the risk of errors or complications is considerably reduced.

It is very important to highlight in this sense that the type of laboratory with which it works, the technology that it uses, as well as the materials used for the metal alloy and the ceramic, will determine the final price of the crown.

Conclusion: about implants in molars

You will have seen that the usual process to place an implant in a tooth has a certain complexity and from us we always recommend that you go to trusted and professional dentists.

There are certain aspects that make a person an ideal patient to get implants and that cost other people more.

In fact, in some cases it gets complicated and infections and dental implant problems arise, but as always if you have a good specialist, they will surely answer all your questions.
