Dental Implant Surgery Explained

Most of us know by now that dental implant surgery is the best option to replace missing teeth, but most of us don’t know is how dental implant surgery is carried out. Here is a dental implant surgery guide so you know exactly what to expect before sitting in the dental chair.

dental implant surgery step 1Step-by-Step Guide for Placing Dental Implants

The proper placement of a dental implant is, so great care should be taken in the first part of the procedure. We start by accessing the patient’s jawbone through the gums and then drilling a pilot hole into the jawbone for the implant’s placement.

Before any of the actual dental implant work can be completed, the patient should be put under anesthesia. Anesthesia method will depend on the office, the availability of anesthesia types, and the preference of the patient. While local anesthetic is the most common choice, sedation is also an option, especially for patients who may find general dental work particularly difficult or intimidating.

Step One: Reaching the Jawbone for Evaluation

The first step in the dental implant procedure is preparing the jawbone. This can be done in one of two ways, depending on the initial evaluation of the patient’s mouth.

  • Method One:  Peeling the Gum Tissue Back – This is the most common method for reaching the jawbone. In order to peel back the gum tissue, a scalpel is used to create an incision–then a dental elevator is used to peel the gum tissue back creating a flaps. Once exposed, the jawbone is evaluated to ensure it’s a match for an implant.  An ideal bone will be smooth and even.  If it’s not, a drill can be used to reshape the bone to accept an implant.
  • Method Two: Circular Incision – Sometimes, a less invasive option is available via a small circular punch. During the procedure, a small, round section of the gum is removed. Because the small area of exposed bone is too small for evaluation, this can only be done when the dentist is experienced enough to ensure the bone is fit for an implant.

Step Two: Locating the Ideal Implant Site

With the bone exposed, it’s now time to use a bur to make a mark on the bone where the implant will be placed. This tiny indent commonly called a divot will be used to both mark the site and guide the larger pilot drill to come.

Next is the creation of a pilot hole. This is a small hole created using a small diameter drill called a pilot drill. To ensure the pilot drill is exact, a pre-created jig (sort of like a mouth guard) is used. The guard has a hole over the implant site so that the drill bit can easily find in correct spot.

Step Four: Checking the Current Work

With the use of an alignment pin, the dentist will check their work to ensure the placement is straight up and down, centered, and properly aligned with the other teeth.

Step Five: Finishing the Pilot Hole and a Second Alignment Check

At this stage, initial adjustments have been made. The positioning is complete, so it’s time to finish the pilot site and run a final alignment check.

Slowly and carefully, not to overheat the bone, the pilot hole will be drilled to the full depth of the implant. Once drilled, the alignment pin will be reinserted to ensure the hole is still straight and centered. If placement is acceptable, the next stage of fitting the implant can begin.

Step Six: Drilling the Implant Hole

Using bits of increasing size, the dentist will slowly drill into the bone to create a hole that will fit the implant’s anchor with most measuring around 4mm. The alignment pin will again be inserted to check the hole, and once any adjustments have been made its time for next step.

It’s time to thread the bone. The smoothly drilled space now needs to be given the same ribbed appearance as a screw. To achieve this, a screw tap will be slowly drilled into the hole. If available, the dentist may also choose to use a self-tapping implant. Self-tapping implants created the ribbed pattern in the bone as they are inserted. Either way this allows for a firm, fitted, secure implant.

When a self-threading implant isn’t available, the next step is to place the implant. Using either a drill or hand wrench, the implant is threaded into the bone.

Step Eight:  Healing Up

Before any further work can be done, the bone and implant need to heal. You want them to fuse to form a steady root for your new dental fixture–whether that be a crown or denture.

Once the implant has been placed, a healing cap is inserted on the top; then the gums are gently set into place over the bone and around the cap. The gums will require trimming, so they rest comfortably around the implant, and once situated, sutures can hold them in place.

Typically, sutures are left in place anywhere from a week to ten days. Following this time period, a dentist will remove them and ensure the health of the site. An additional six months is needed for the bone to fuse with the new implant.  Some dentists require that the implant is kept with the healing cap in place.  In other cases, depending on the stability of the implant, size of the area, and type of tooth, a temporary tooth can be placed on the healing cap. This can only be done if the dentist believes the use of the tooth won’t affect healing or cause the implant any trauma.

implant surgery step 4Step Nine: Permanent Restoration Placement

So, you’ve gone through the drilling and implant placement. You’ve waited six months or more for healing. You’ve treated your implant site with care and kept it clean. You’re ready to get the final piece of the puzzle.

The healing cap is removed, and an abutment is placed. This is a nub, for lack of a better term, which will serve as the port where the dental prosthetic will be screwed into.  The pre-created dental crown is then screwed onto the abutment, and the process is complete.  It’s now up to the patient to properly care for and clean the crown each day.

It should be noted that implants can be made as bridges or dentures as well. Denture implants with special dentures that are secured into place via implant anchors. These can be placed and fixed in the mouth at this stage as well. If multiple implant sites are needed, the above dental implant procedure would be followed for each section–likely during one sitting, then allowed to heal as a group. Once recovered, the full denture or bridge can be placed.
