IMPLANTS

 Introduction:

A dental implant (also known as an endosseous implant or fixture) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor.

Tooth Loss:

Tooth loss is normal with baby teeth, where at some point in a child’s life, a tooth becomes lose and then falls off, but is later replaced by an adult tooth. Otherwise loosing a tooth is unfavourable and if it happens with adult teeth, it’s the result of injury, tooth decay or periodontal disease. Decades ago it was considered normal to lose your teeth as you grew old.

Importance of Dental Implants:

Dental implants help maintain and strengthen bone structure. This means they do much more than replace a missing tooth , they also protect existing teeth by helping to preserve bone structure. Once a tooth is lost, several things begin to happen that are not immediately noticeable to a patient and which can have a significant negative effect on both health and appearance. Tooth roots help hold teeth in place, but they are also critical in maintaining health in the surrounding gums and supporting bone structures. Bone loss in the jawbone is one significant problem that naturally occurs once a tooth is lost. This bone loss can compromise the integrity of neighbouring tooth roots and tooth stability, and it is also a large part of what causes the “sunken” look that is seen in people who have lost several or all of their teeth.

Types of Dental Implants

Based on the material

Titanium Dental Implants

The initial implants were pure titanium, but they were a bit too soft so an alloy was developed to overcome the negative properties. Today, well over 95% of the dental implants placed are titanium alloys, there has not been one report of an allergy or reaction to the metal itself. Titanium fuses to the bone very well.

Zirconia Dental Implants

Several companies have conducted research and development into “metal-free” implants. This has led to the use of another metal called zirconium, which is just one row below titanium in the chemical periodic table.. Zirconium first became popular in its crystalline cubic zirconia form due to its resemblance to a flawless diamond. The material is very strong and hard and has also been used for making crowns and bridges. With the search for alternative implant materials, it was discovered that zirconia also fused to bone (osseointegrated) much like titanium

Titanium and Zirconia—Pros and Cons

Both materials can integrate with bone with equal success provided certain protocols are  followed. titanium dental implant

Titanium implants are much more versatile than zirconia because they can be made as one piece or two-piece systems. In two-piece systems, the implant replaces the root and is generally placed at the level of the underlying bone. Attached to this is a post or abutment—the part that sticks through the gums and is used to support or attach the teeth.

Two piece systems are a lot more versatile and offer many more options prosthetically. They can be used for overdentures (removable teeth) that snap into place as well as permanent teeth that are cemented or screwed onto the implants. Additionally, the implant can even be placed slightly off-angle and an angled or customized post can be fitted to correct it. Zirconium implants can also be modified if they are slightly off but are not as prosthetically ideal as what can be done with a separate post.

In some cases, placing an implant slightly off-angle is not a surgical error, but rather a necessity due to the volume and location of bone in the implant site. Basically titanium implants offer much more versatility with the final teeth and flexibility with their surgical placement.

Zirconium implants (the implant body and the post or abutment) on the other hand, are made as one piece. Therefore, the only option for the prosthetics is to cement the teeth into place. Secondly, there is very little room for error—one has to be very careful not to place an implant at an improper location or angle. Therefore surgical placement and volume of bone is absolutely critical.

In case if needed placing a bone graft in zirconia implant is little difficult.Both types of implants require several months for the bone to fuse or grow against the implant before we can place the final teeth. With one-piece zirconia implants, this healing phase can be a little more tricky as we cannot bury the implant under the gum tissue. if there is pressure or movement of the implant, it will not osseointegrate.

Another concern is the long-term strength. We no longer see fracture of titanium implants since the alloys were introduced, but zirconia implants have been known to fracture. If this occurs, usually the only option is to remove them and that can create a large defect in the bone.

Based on the Shape

Cylindrical Dental Implants

The dental implants available come in different shapes, and cylindrical is one of them. The coating and surface condition is what will determine whether or not to use cylindrical dental implants as the coating and the surface provide bonding and microscopic retention with the bone. The cylindrical implant can be conical, straight or tapered and is tapped or pushed into the bone site that has been prepared.

Root Form Dental Implants

Root form dental implants are a commonly used type of dental implant. Dental implants are used to replace missing teeth. A root form dental implant is made up of three parts:

  • a titanium device resembling a screw that a dentist inserts in the jawbone
  •  a metal structure called an abutment that is attached to the top of the implanted portion and sits above the gum line
  •  a crown, denture, or bridge that is placed over the abutment and replaces the missing tooth or teeth

Based on its Placement

Endosteal dental implant

There are three types of endosteal implant. There is the blade implant where thin plates are embedded into the jawbone, Ramus frame implant where a horse shoe-shaped device is inserted into the mandible and root form implant that takes on the shape of a normal tooth. The root form implant is the most common of the three, and the implant is positioned in such a manner that it offers directional load distribution.

Subperiosteal implant

This is a type of implant where the artificial tooth is placed beneath the periosteum that overlies the cortex. Here the jaw bone is not necessarily drilled. Much of the support is provided by the gums and how the implant lies on the bony cortex.

Transosteal implant

This type of implant can, also, be referred to as staple bone implant, mandibular staple implant or transmandibular implant. This type of implant is a combination of both the endosteal components and those of subperiosteal. The implant penetrates the two cortical plates.

Intramucosal dental implants

As the name hints, this type of implant is inserted directly into the oral mucosa. In this case, the mucosa is used as the site for attachment and the metal inserts, usually made from titanium.

Fibrointergration implants

In this type of implant, the implanted tooth is completely encapsulated by the soft tissue in the mouth.

Based on the Surface

Threaded dental Implants

When you look at the surface of the implants, you will see threads. This is where the name of this implant roots from. The main purpose of the threaded surface is to increase the implant’s surface area hence providing a more solid contact with the jawbone. The threads result in the implant being in contact and subjected to force over a greater bone volume.

Vented dental implants

This type of implant is a cylinder that has been coated with hydroxy apatite. They have a vertical groove that connects to the apical veins. This facilitates seating, and the bone growth into the groove prevents rotation.

Hollow dental implants

The hollow dental implants have a hollow design in their apical portion. There are perforations on the implant’s sides that have been arranged systematically. The perforations are meant to increase the anchoring surface and prevent the implant from twisting and moving.

Smooth, machined, textured and coated surface implants

The smooth surface implants have a smooth surface.Machined surface implants are those whose surfaces have been machined for better anchorage.Textured surface implants have a rough surface for increased surface area, and the coated surface implants are those whose surfaces have been covered by a porous coating, usually titanium or hydroxy apatite.

Based on the Reaction

Osseointegration

Osseointegration is the formation of a direct interface between an implant and bone, without intervening soft tissue”. Osseointegrated implant is a type of implant defined as “an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate”. Applied to oral implantology, this thus refers to bone grown right up to the implant surface without interposed soft tissue layer.

Two Stage Implant:

With two stage surgery, the day the surgery is performed the implant is completely covered. Three to six months later another surgery is done to expose the implant and place the healing abutment. The type of surgery chosen is determined by the amount and quality of bone that you have at the time of surgery.

Osseofixation

Dental stemmed devices are designed to occupy the chamber created in a passive but biomechanically locked, immovable manner. Once a device is seated altering the position is impossible. This stability allows the bone forming cells to complete the fixation phase by osseointegrating. It is a well known fact that osteoblasts cannot hit a moving target which may explain some of the failures of dental implants.

Some of the types are as follow :-

BASAL Implants – BOI Implants and Basal screws – bone grafts are history!

BOI implants are the most advanced system within the group of Basal Implants. These implants are well designed for immediate loading and therefore you get your permanent fixed teeth immediately in 3 days. These implants have a high success rate for patients who are:

  • smokers,
  • having bone with less height
  • Gum disease.

C:\Users\hp\Desktop\Basal-description-Copy.jpg

The term “Basal Implant” refers to the implants based on the principles of utilizing basal bone areas which are free of infection and resorption. The “Basal Implant” employs the cortical bone areas as such the patient’s chewing function becomes normal and even an old patient can chew hard food like nuts etc.

These simple devices but none of them are even equipped with any kind of prepared surface for the enhancement of bone regeneration.

They Seem to solve all principal problems of our profession today: Basal screw implants and BOI implants are independent of presence of bone volume in vertical dimension. This leads to completely changed therapeutic option in the upper jaw. Sinus lifts have become avoidable because all patients have sufficient horizontal bone naturally, even if vertical bone is missing.

Structure/Design of Basal Implants

Lateral basal implants are inserted from the lateral aspect of the jaw bone. With a disk-diameter of 7mm or more, they are inserted through a T-shaped slot in the jaw bone.

Screw able basal implants are flapless implants and are placed through gum, without giving a single cut.

Many options for immediate implant placement and implant loading in the upper jaw are available. Today sinus lift is a time-and money-consuming procedure. Today, the application of traditional implants connected to sinus lifting procedures needs a good reason because minimal invasive options are available and should be a part of complete information to a well informed patient.

With axial implants, implant patients were forced to undergo four different surgical procedures over a one year period in order to receive implants:

  • Extraction of all diseased teeth, curettage of granulation tissue, and preparation of the gingiva.
  • Bone grafting after two months, with an additional surgery at the donor site.
  • After six months of bone graft healing, insertion of the implants will be placed.
  • After another six months of implant healing, crowns are placed.
  • Sometimes patients are subjected to additional periodontal surgery.

Patients desirous of getting fixed teeth had to wear dentures for another year when treated with axial implants.

The All-on-4 treatment concept was developed to provide edentulous patients with an efficient and effective restoration using only four implants to support immediately loaded full-arch prosthesis.

The All-on-4 treatment concept offers clinicians and their patients various clear benefits:

C:\Users\hp\Desktop\all-on-4-implant-cost.jpg

  • Stability even in minimum bone volume
  • Good clinical results
  • Planning with Nobel Guide treatment concept
  • Prosthetic flexibility
  • Increased efficiency

Zygomatic Implants

C:\Users\hp\Desktop\original-2016-12-29_14-03-29.jpg20170104-29720-fl926f.jpg C:\Users\hp\Desktop\original-zyg_quad.jpg20170104-29720-j09w0j.jpg

These are used when there is insufficient bone to hold a normal dental implant. The difference between a Zygomatic Implant and a normal dental implant is that the former is longer and is placed diagonally into the cheek bone (zygoma), to make use of it , usually after extracting a tooth, the bone that held the tooth starts to shrink. In some cases the shrinkage is severe resulting in insufficient bone to hold a dental implant. This usually means a sinus lift and bone graft is required to build up bone structure and achieve better stability. In certain cases we can place longer Zygomatic implants into the cheek bone, giving better stability and strength to hold a implant retained bridge, and thus sometime negotiating the need for a bone graft. Zygomatic implants are placed carefully avoiding the sinuses, also eliminating the need for sinus lifts. Dental implants are a great solution to replace missing teeth, but can involve a 6 month period of waiting for the implant to fuse with bone before placing teeth onto the implants. With Zygomatic implants, you can place a bridge onto the implants straight away; therefore you will walk out of the surgery with a brand new smile.

Single Tooth Missing

The single tooth implant restoration consists of three parts. Namely, the implant post which replaces the tooth root, the abutment which will support the crown and the prosthetic crown itself. The crown is either cemented onto the abutment or held in place with a screw.

With today’s developments, there are a variety of implant systems, models and ranges available. Each line catering to the individualized needs of patients.

A single tooth implant with crown is one of the best permanent restorations. This solution both looks and functions just like a natural tooth.

Multiple Teeth Missing

If multiple teeth are missing in different parts of the mouth, several single tooth implants are good replacement restorations. If multiple teeth are missing within the same region, several missing teeth can sometimes be replaced with fewer implants because dental implants are stronger than the natural tooth roots. This solution includes having implant fixed bridges done.

C:\Users\hp\Desktop\full-arch2.png

An implant fixed bridge is very much like a conventional bridge except the support is actually over implants rather than natural teeth. The implants themselves act as man-made roots. A great advantage is that this is that it is self-supporting unlike conventional a tooth supported br idge that puts a heavier load on the remaining teeth.

Dental implant procedure is the term used to describe the entire process you go through from the time you walk into the dentist’s clinic for the first time, when getting your dental implants, till the last time you walk out of there with your new beautiful smile. The dental implant procedure involves two main stages separated by a minimum of 3 and up to 9 months of healing time

Dental implant surgery

This is the step where the dentist inserts a metal screw into the jaw bone. This screw (The implant) is inside the jaw-bone and is not visible. There is an abutment that is screwed onto it and it is the abutment that is visible. In the event that the work is being done in a visible area (like the smile line), the dentist will place a temporary covering on the abutment for aesthetic purposes. The next step is the implant restoration. So It all starts with the dentist introducing a local anaesthesia into the relevant area, It is then cut and an incision is made on the gum’s soft tissue creating a flap in order to expose the jaw bone.
The dentist then inserts the implant in the hole and screws it down using his dental motor or using a manual ratchet. Once the implant is in place the flap is then stitched up. The whole process can last for an hour a single implant and a few hours for a multiple implant case.

Implant restoration

It takes time for the implant to take hold. This could range from 3-9 months, depending on the individual’s rate of healing. Once the implant is firmly set inside the jaw bone, then the permanent crown is attached to the abutment. The crown is built of material that will match the surrounding teeth.
