It is also known as a fixture or Endosseous Implants. It is a surgical component that aligns with the bone of the jaw or skull to support a dental prosthesis such as denture, crown, bridge, facial prosthesis. This is the physical and mechanical process in which a strong bond to the bone is made using TITANIUM. The oral health of a person who is receiving treatment is dependent on the success or failure of implants, the health of the tissues of the mouth, and the drugs which enhance the rate of Osseointegration. The amount of stress that will be put on the implant and fixture is also evaluated to make sure that it can bear it.
Main Procedures of Dental Implant(1): – Some basic implant procedures are defined as below.
1. Placing the Implant: – For each placement of the Implant, we have five basic steps.
- Reflection of soft tissue: – A cut is made over the crest bone, cut the strongly attached gingiva roughly in half, so it will have a thick band of tissue of the final implant around it. To expose the bone, the edges of the tissue are removed and a flap is pushed back. For implant placement, other than raising flaps, where a small punch of tissue is removed, flapless surgery can also be performed.
- High Speed Drilling: – Main holes are placed with precision drills at regulated high speed, after reflecting the soft tissue, a tube is placed as necessary for preventing of burning or pressure necrosis of the bone by excessive drilling.
- Low Speed drilling: – By using progressively wider drills, the pilot hole is expanded. To prevent damage to the osteoblast, care is taken. To keep the temperature low, keep water spray or cooling spray near you.
- Implant placement: – It can be self – trapping where implant screw is placed, otherwise an implant analog is tapped with the prepared site. With a torque-controlled wrench, it is then screwed into place, not to overload the surrounding bone.
- Adaptation of tissue: – The entire implant is adapted by the gingiva to give them a thick band of healthy tissue throughout the healing period.
2. After extraction of teeth, place the implants: – For the placement of dental implant after tooth extraction there are several approaches, which are defined as.
- Instant post–extraction implant placement.
- Delayed instant post–extraction implant placement.
- Late implementation.
The placement of a dental implant into a recent extraction site to preserve bone and reduce treatment is an increasingly common strategy. On the first side, it can improve aesthetics and shortens treatment time because it preserves the soft tissue envelope. On the other side, it has a higher rate of the initial failure of implants.
3. One versus two–stage surgery: – With a healing system or cover placed after an implant is placed, the internal components are covered. Through the mucosa, the healing gel passes and it is adapted into the surrounded mucosa around it. To reflect the mucosa and place a healing abutment after an integration period, a second surgery is required. This surgery is called two-stage surgery.
The risk of a failed implant can significantly minimize by the patient’s personal observation. Always be prepared, don’t wait for the problem.
Causes of Dental Implant Failure: – it can fail at an early or late stage. The most common causes of dental implant failure are.
Early stage: –
- Mini – movements.
- Infection
- Lack of compliance with the guidelines suggested by the dentist
- Allergic reactions.
- Subprime implant positioning.
- Inadequate bone support.
Late stages: –
- Implant Dental rejection.
- Damage of tissue and nerve.
- Infection
- Injury
The failure of an implant depends on many risk factors. The most common are:
- Inadequate proper aftercare
- Bruxism
- Smoking
- Poorly oral hygienic.
- Gum disease.
- Placement of the mandible rather than in the maxilla.
- The shape of non – cylindrical implant.
Dental Implant Failure signs: – Signs that can signal dental implant failure are as follows.
- Swallowing / chewing difficulties.
- Inflammation of gums.
- Rod loosening.
- Severe pain.
Only some people experience dental implant failure otherwise it has a high success rate. About 5 to 10 % are estimated of dental implant failure either after a procedure or month or years later.
How long Dental Implants lasts(2): – The revolutionized modern dentistry offers dental implants which have tooth replacement options. The same look and function of natural teeth are provided by these permanent solutions. The extent of dental implant longevity depends on several factors such as the dentist’s skill, implant quality, your health, the implant placement, and your oral care.
The dental crown is the visible part of tooth – replacement system. In fact, it must be replaced after every 5 to 15 years. Here are some factors that are additional that often impact how long implants will last. Such as the usage of your teeth, your implant placement, and your lifestyle and diet.
Dental implant – an investment: – When compared to other tooth-replacement methods, dental implants look surprisingly expensive. The two alternatives dentures and bridges have to be replaced after 5 to 10 years. The cost of simply turning to implants quickly outstrip the cost of regular maintenance, which can last a lifetime. They protect your Jawbone from deteriorating. On the other hand denture and bridges can’t do it. You’ll start looking older as your jaw deteriorates. Due to these reasons, we might think that implants are an investment nor an expense.
Dental Implant Costs: – In general, every case is unique, however, the cost of a single dental implant is $ 15,00 to $ 2,000 per implant. Some patients need only a single implant whereas the others need several implants. It is not the only cost of a dental implant, there are other expenses involved such as:
- The crown.
- The abutment.
- Root extraction and tooth cost.
- Office visit cost.
- Pre-op care.
- Post-op care.
These costs range from $1500 to 2800. For a single implant total cost is in the range of $3000 – $ 4800. If you want zygomatic implants you can expect slightly higher costs. It is a little longer than a regular implant because it requires more skill and training to place. These are specially designed for those patients with significant bone and gum loss. If you avail zygomatic implant you’re only paying for one surgery, not two. They allow you to skip Bone Graft Surgeries that’s why they are great.
