Dental implants (Implantology)

In case of missing a tooth or a group of teeth, you need to go through a dental implant procedure. In simple words, when a non-natural tooth root replace with a defective organic one, it is called dental implants.

At Dr. Prof. Asheesh Gupta’s clinic for dental implants in Delhi at our Rohini Clinic or Pitampura Clinic, tooth implant procedure or surgery is done using local anesthesia or general anesthesia especially depending on the case.

Integration and healing of the implant or implants with jawbone happens over 3 to 6 months after which the bridges/crowns are attached and fabricated to the certain implants.

Dental implants are natural-like roots manufactured using titanium material. Being made of high-quality materials these implants feel like natural teeth root, and are positioned within the human bone. Further, they are of superior quality and more affordable than traditional dentures just because of their exceptional grinding and chewing properties and superior fitting.

They function as an anchor for a human tooth movement. Hence, if you are looking for best option for replacing missing teeth, we at Dr. Prof. Asheesh Gupta’s Dental and Braces Clinic (Rohini/Pitampura, New Delhi) have low-cost but high-quality of implants to make you smile.

We at Dr. Prof. Asheesh Gupta’s Dental Clinic have incredible excel in performing intricate tooth implant procedure or surgery. We make sure that our valuable clients like you get the best possible as well as economical services when it comes to dental implantation. If you are looking for best clinic for dental implants in Delhi, you need to look nowhere else but Dr. Prof. Asheesh Gupta’s Dental and Braces Clinic.

Procedure

Natural looking, comfortable and custom-crafted, these take more time to establish in than traditional dentures. Hence, for these to settle in, a small hole is drilled into the human bone and thus in this hole the implant is positioned. The tiny hole is usually 1 millimetre.

While making this hole, great care is also taken as not to demolish the organic bone cells or other nerve of human jaw-line. Usually, tooth implant may take a longer time to adjust or heal – around four to five months. Further, high cleanliness and sterilization is maintained throughout the procedure.

What is dental implant?

A dental implant or also called fixture or endosseous implant is a modern surgical module that interfaces with human bone of the skull or jaw to support an available dental prosthesis like bridge, crown, facial prostheses, denture, and to function as an available orthodontic anchor.

The fundamental for contemporary dental implants is a kind of biological procedure known as osseointegration where high quality of material, say for instance titanium builds an intimate relationship to bone. An implant fixture is usually first positioned so that it can osseointegrate, and then an available dental prosthetic is included.

A good recovery time is needed for osseointegration even before either the available dental prosthetic like denture, bridge and tooth is bonded to an abutment or the implant is positioned that will hold an available dental prosthetic.

Failure or success of the implants largely depends on the current physical condition an individual getting it, health of natural tissues found in mouth, and medication which influence the chances of the osseointegration. The great amount of stress that may be put on the fixture and implant during usual act is also assessed.

Further, planning the right position as well as number of required implants are main reasons to a long-lasting health or durability of prosthetic because biomechanical forces originated during chewing may be important. Remember, the position of a tooth implant is determined by current angle and position of an adjacent tooth or teeth, modern lab simulations or by utilizing computed tomography with CAM/CAD simulations as well as surgical directions known as stents.

It is a known fact that the prerequisites to a long-lasting success of contemporary osseointegrated dental surgery or implants are gingival and healthy bone. Further, since both may atrophy after a tooth extraction pre-prosthetic processes like gingival grafts or sinus lifts are often needed to reconstruct the ideal gingiva and bone.

The last step or final prosthetic may be either fixed, wherein an individual cannot eliminate the teeth or denture from their removable or mouth, where they may eliminate the available prosthetic. However, in every case, the abutment is included to the available implant fixture.

Moreover, wherein the prosthetic is joined, the bridge or denture, crown is included to the abutment either with cement or lag-screws. And wherein the prosthetic is movable or removable, an equivalent adapter is positioned in the available prosthetic especially that the two pieces could be thoroughly secured together.

The complications and risks associated with implant treatment can be divided into those that usually happened during the procedure like nerve injury or excessive bleeding, those that happen in the initial 6 months like failure and infection to osseointegrate and those that happen long-term like mechanical failures and peri-implantitis.

If the healthy tissues are available, a thoroughly integrated implant along with right biomechanical loads will have about 93% to 98% of success rates for the fixture as well as a lifespan of ten to fifteen year for the available prosthetic teeth.

Planning, technique and general considerations

Planning for the artificial dental implants concentrates on the normal health condition of an individual, the current health situation of the jaws, mucous membranes and position, shape and size of bones of human jaws, opposing and adjacent teeth.

There are some health situations that certainly exclusive positioning implants however there’re particular conditions that may maximize the risk of procedure failure. Individuals with bad oral hygiene, diabetics, and smokers are all at higher risk for an array of gum disease that may affect implants known as peri-implantitis, enhancing potential risk of long-term failures.

Further, osteoporosis, continuing steroid use and other several diseases that impact that natural bones may increase the potential risk of unwanted failure of teeth implants.

Biomechanical considerations

It is a well-known fact that long-lasting success of teeth implants is partially determined by the arrangement they have to hold. Since implants have no available periodontal ligament, there’s no feeling of pressure while biting thus the forces created would be higher. Further in order to offset it, the position of implants should distribute required forces thoroughly throughout the prosthetics they hold.

Focused forces may result in fracture of the artificial bridgework, loss of natural bone adjacent the artificial implant and implant components. The final location or position of an implant is based on both mechanical and biologic (vital structures, health, bone type) factors.

Remember, implants positioned in stronger, thicker bone like that available in the frontier area of the bottom jaw have lesser failure chances than implants positioned in lower bone like the back side of the natural upper jaw. Individuals who grind their natural teeth also enhance the force on available implants and thus increase the chances of failures.

The overall design of an artificial implant has to account for long-lasting use in an individual’s mouth. Dental implant business and regulators have established a series of authentic tests to assess the long-lasting mechanical authenticity of implants in an individual’s mouth wherein the artificial implant is walloped repeatedly with enhanced forces until it fails.

Apart from that when a clearer plan is required beyond contemporary clinical assessment; the dentist can make an acrylic guide also known as stent just prior to dental surgery that guides most favourable positioning of the implant. Moreover, dental professionals opt to receive a CT scan of the existing dentures and jaws, and then determine the surgery.

It is time when stent could also be constructed using stereo lithography following contemporary computerized assessment of the case from the modern CT scan. Remember, with the help of CT scan of complicated cases, dental surgeon can easily recognize and prevent vital structure, say for instance the sinus and lower alveolar nerve.

What are the surgical procedures for placing the implants?

Most of the implant systems come with total five fundamental steps for positioning of each artificial implant.

• The first usual step is called mild tissue reflection. In this process, an incision is built over the top of natural bone, dividing the thicker joined gingival in half so that the ultimate or final implant could have a thick structure of tissue around this. Further, the edges of soft tissues, each named as flap are forced back to unveil the bone. The flapless surgery is considered as an alternate method wherein a tiny punch of soft tissues is eliminated for artificial implant rather than lifting flaps.
• Second step involves the drilling. Having reflected the soft tissues as well as using a stent or surgical guide as essential, pilot holes are positioned with careful drilling at very high speed to avoid pressure necrosis or burning of the natural bone.
• Remember, drilling should be done at low speed. The required pilot hole is extended by using innovative wider drills (usually between 3 and 7 consecutive drilling points, depending on artificial implant length and width). Further, great care is needed to ensure bone cells or osteoblast damage. A water spray or cooling saline may keep the temperature low.
• Now, come to the positioning of the artificial implant. The artificial implant screw is positioned and should be self-tapping else the prepared space is tapped with the implant analog. Now, it is screwed into positioned with a torque managed drill at careful torque so as not to overburden the available bone. An overburden bone may die, a condition known as osteonecrosis that may be able to lead to failure of artificial implant to thoroughly bond or integrate with the natural jawbone.
• Now, the last and most important step called tissue adaptation. Remember, the gingival is thoroughly adapted around the whole implant to offer a thick group of healthy soft tissue around the recovering abutment.

Timing of artificial implants after tooth extraction

• Instantaneous post-extraction dental placement
• Delayed instantaneous post-extraction dental implant placement – 2 to 3 weeks after extraction
• Late dental implantation – 3 months or more after natural tooth extraction

There are also several alternates available for when to include teeth to artificial dental implants, grouped into:

• Instant loading process
• Initial loading – 1 week to 12 weeks
• Delayed Loading – about 3 months

Healing or recovery time

For an artificial implant to become permanent, human body should grow bone to the existing surface of an implant or osseointegration. Hence, based on this basic biologic procedure, it was assumed that loading a dental implant especially during the osseointegration time would outcome in movement that would avoid osseointegration, and hence enhance implant failure chances.

As an outcome, 3 to 6 months of integrating period (depends on several factors) was enabled before positioning the teeth on the implants.

Conversely, later research recommends that the starting stability of the dental implant in organic bone is more significant determinant of getting success of dental implant procedure, rather than a particular period of recovering time.

As an outcome, the time duration enabled to recover is traditionally depended on the density of natural bone the artificial implant is positioned in as well as the number of artificial implants integrated together, rather than a certain span of time.

One-stage and two-stage Surgery

Having positioned an implant, the internal parts are occupied with either a cover screw or healing abutment. A recovery abutment passes through available mucosa, and the available mucosa is placed around it.

Moreover, a significant cover screw is colour with natural surface of the implant, and is developed to be thoroughly occupied by mucosa. A second surgery is needed to depict the mucosa as well as position a healing abutment especially after the integration period.

When soft tissue is mutilated or deficient by the loss of natural teeth, dental implants are positioned and thus enabled to osseointegrate then the available gingival is medically or surgically revolve around the recovery abutments.

The demerit of a two-level method is the necessity for extra surgery and simple compromise of natural circulation to the soft tissue because of repeated surgeries. The option of two and one-stage, presently establishes around how perfect to re-establish the tissues around natural lost teeth.

Immediate placement

Immediate placement is an enhanced usual method to preserve natural bone and lessen treatment period includes the positioning of dental implants into a current extraction place. One hand, it reduces treatment time as well as can enhance aesthetics as the mild tissue is sealed.

On the other hand, dental implants could have a slightly greater chance of initial failure. However, conclusion of the subject is certainly difficult as some studies have thoroughly compared delayed and immediate implants in a scientifically meticulous manner.

Additional surgical methods

In order to implant to available osseointegrate, this requires to be thoroughly surrounded by a natural and healthy bone. For it to survive long-standing, it requires to have a healthy, thick and soft tissue or gingival envelop especially around it.

This is certainly usual for either the soft tissue or bone to be scarce that the dental professionals need to reconstruct it either during or before implant placement.

Hard tissue or bone reconstruction

Bone grafting is needed when there is absence of bone. However, there’re always innovative implant techniques and types to enable compromise but a usual treatment motto is to have at least ten millimetres in natural bone height as well as six millimetres in width.

In order to accomplish a sufficient height and width of bone, several bone grafting methods have been created. The guided natural bone graft augmentation is considered among the most frequently applied technique. In this technique, a bone defect is thoroughly filled with either allograft (synthetic or donor bone replacement) or natural (autograft or Harvested), occupied with a semi-permeable available membrane and enabled to treat.

Moreover, during the recovery period, organic bone replaces the available graft making a new bony foundation for the desired implant. The three most usual procedures are:

• Sinus Lift
• Increase in the main width of a space or lateral alveolar enhancement or augmentation
• The vertical alveolar enhancement or augmentation (enhance in the natural height of an available site)

Another more invasive processes, also available for bigger bone defects adding mobilization of the lower alveolar nerve to enable placement of a desired fixture, thus natural bone grafting utilizing iliac crest or other bigger source of microvascular bone graft and bone where the organic blood supply to the natural bone is placed with the original or source bone and reattached to the current blood supply.

The ultimate decision regarding which bone grafting method that is most suitable is based on a measurement of the degree of horizontal and vertical bone loss that present, and each of which is thoroughly classified into soft (2-3 millimetre loss), medium or moderate (4-6 millimetre loss) or complicated (bigger than 6 millimetre loss).

Advantages of dental implants

• New dental implants will feel and look like organic teeth
• Moreover, with an innovative dental implant, you will be more confident while smiling and easily bite anything eatable
• Remember, dental implants are capable of replacing a removable denture along with fixed teeth
• Your dental implants prevent your bone and gums from shrinking which decreases the aging impact caused by natural tooth lost

Dental implant surgery is never a painful procedure

We at Dr. Prof. Asheesh Gupta’s Dental and Braces Clinic make sure that our valuable patients feel quite comfortable during the dental implant placement. Thus, we use an effective but easy to use local anesthetic. Further, post-operatively we also prescribe painkillers to our patients to ensure that they remain comfortable.

How long does dental implant treatment take?

For normal cases, dental implants treatment time is normally between 12 to 16 weeks. However, more complicated cases may take longer time. Parameters such as patient’s current medical status, bone grafting, and bone volume can also augment the treatment time. Remember, more specific dental implant treatment schedule could be explained after the first consultation.

How often patients need to have their dental implants checked?

It is necessary that you must continue to manage or maintain excellent oral hygiene as well as regular bi-annual medical check-ups. It is recommended that at least once in a year, you need to consult with your implantologist to ensure the durability of your dental implants.

Are you the right individual for dental implants?

A normal health and missing teeth can make you eligible to go through dental implants procedure. Remember, apart from a few medical situations or conditions, almost anyone can go through dental implants process.

• Bruxism and uncontrolled diabetes are two medical conditions which don’t favour a desired end outcome. However, if the diabetes can be controlled or managed, one can easily accomplish desired outcomes with implants.
• In case of being a smoker, you need to quit smoking minimum for ten days after going through dental implants procedure, until the gums heal thoroughly.
• You also need to have good quantity and quality of bone for dental implant placement. But, individuals who have lost great amount of bone may also qualify for desired dental treatment with certain extra processes to create a new bone.
