People lose  teeth all the time, either through trauma when teeth are knocked out (athletes  such as rugby players, soccer players and boxers commonly experience this) or due to decay, gum  disease or old age. Whatever the reason for loosing your teeth they need to be  replaced both for aesthetic and functional reasons. The most common treatments  for missing teeth are either a denture or a fixed bridge. However, dental  implants are now becoming a more popular treatment to replace missing teeth as  they provide a longer-term solution, slow down bone loss and preserve nearby  healthy tooth tissue. What is a dental implantA dental  implant is an artificial substitute / replacement for the root portion of your  natural tooth and is anchored into a pre-drilled socket in your jaw-bone to  support a crown, bridge or secure a denture firmly in place. Implants are made  from titanium, a material that is well tolerated by bone and integrates easily  with bone tissue. During the placement of a dental implant the goal is to  achieve a close contact between the outer surface of the implant and the  surrounding bone tissue so they can fuse together (osseointegration) creating a stable support for the new teeth.

The Implant Procedure

Before any  implants are placed it is important for your dentist to assess the health of  your teeth and gums, if there are any signs of gum disease or decay these must  be treated first. Following this your treatment will be planned following several  x-rays and a CT scan in some cases to assess that bone quality and check for  nearby anatomical structures to avoid before any drilling. The procedure is usually carried out under local anaesthesia and sometimes IV sedation if it is a long procedure or the patient is very anxious.The gum  where the implant is to be placed is cut and lifted and a small hole is drilled  in the jawbone at the precise location of the intended implant. The titanium implant is tightly fitted into this socket and the gum is stitched back over the implant. If there is insufficient bone material to accommodate the implant a bone graft may be required or alternatively the dentist may use smaller sized  mini implants if suitable. Once the implant has been placed it is left to heal and integrate with the jawbone for between 6 weeks to 6 months. The bone tissue will grow and anchor itself into the microscopic rough surface of the implant. During this healing period patients are given temporary teeth (bridges) or continue to wear dentures. It is important that any temporary teeth do not exert any forces on the healing implant.  After the healing period the gum is lifted again and a post is attached to the implant with a temporary crown. Four to six weeks later, when the surrounding gum tissue has matured, the final permanent restoration can be fitted to the implant.

What are the advantages of dental implants over dentures and bridges?

• Reduced bone loss. Normally, the bone tissue surrounding the root of your tooth is maintained by your body’s natural renewal process. However, if you loose a tooth, you will be left with a hole where your tooth root used to be and the bone around this area will slowly begin to disappear (atrophy) and may change the shape of your jaw. A dental implant placed in that area can actually stimulate bone growth and production, preventing loss of valuable bone structure. In some patients where bone loss is substantial a bone graft may be required before placing a dental implant. Bone loss is a problem for people who have dentures and as the shape of the jaw slowly changes the dentures need to be adjusted or re-made to fit the new shape of the jaw. Bone loss can also make a person look older since the area around the mouth can sag as bone is lost-
• Improved function. Once dental implants are fully integrated into you jaw they function just as well as your own natural teeth and you can eat the foods you want and  speak with complete confidence. With dentures, eating hard foods such as an apple can be a problem, either the dentures come loose or patients cannot withstand the hard biting forces as they cause pain in the gums. Irritation and inflammation of the gums is a common problem amongst denture patients. Dentures can be supported by implants or mini-implants which will improve function greatly enabling patients to eat the foods they want with complete confidence and not having to worry about bone loss and loose dentures falling out.
• Improved dental hygiene. Unlike bridges and dentures, which require special cleaning instructions and extra attention, dental implants just need regular brushing, flossing and hygiene appointments just like your natural teeth.
• No need to drill or remove any healthy tooth structure. When replacing missing teeth with dental bridges, the teeth adjacent to the gap need to be prepared and healthy tooth structure is removed to accommodate a crown or bridge abutment to fit over the top of the tooth. In the future if one of the supporting teeth is damaged the entire bridge restoration will also be compromised whereas with an implant the restoration is independent of any of your other teeth. By replacing lost teeth with an implant, no support is required of the adjacent teeth, and hence your natural teeth do not need to be prepared or altered in any way.
• Better aesthetics. If done correctly a dental implant should be indistinguishable from your surrounding natural teeth. Dentures can come loose and look un-natural if they do not blend with your gums and some bridges and dentures have unsightly metal clasps to hold them in place. Dental implants provide a much better cosmetic and functional end result.

How many  teeth can a dental implant support?

Traditionally an implant placed into your bone supports a single crown and this is know as a single tooth implant. However if you have several missing teeth you do not necessarily need an implant for every missing tooth, one implant can support several teeth via a bridge or a denture. The number of implants required  depends on the volume and density of bone tissue available at each implant  site. Often smaller sized mini implants are used to secure dentures in place. In the case of full mouth reconstructions where an arch of several teeth (10+) need to be supported  in either the upper or lower jaw a minimum of 5-6 implants in each jaw would be required. The exact number of implants needed would depend on the individual  case and your implant surgeon would be able to advise you on the best solution after a through examination and assessment.

Am I a suitable candidate for dental implants?

Dental Implants can be placed in patients of any age (with fully developed jawbones)  provided that they have sufficient quality and quality of bone tissue  available. Most healthy individuals that maintain a good oral hygiene program  are suitable candidates for dental implants. Circumstances where implants may not be suitable or situations that have an increased risk of implant failure  include:

• Heavy smoking this slows down and hinders the healing process
• Excessive alcohol intake disrupts healing of the gums
• Periodontal gum disease all active gum disease must be treated prior to any implant procedure to ensure long term success of any treatment. Periodontal disease is a major cause of bone loss, which would hinder the success of any implant procedure.
• Immuno-compromised individuals (steroids, auto-immune disease, patients undergoing radiation treatment).
• Teeth grinders (bruxism) a night time splint can be given to treat this.

How will I  know if I have enough bone for implants?

Using a  combination of dental X-rays and a CT scan (CBCT or 3-D conebeam imaging) your bone density and volume can be assessed as well as information about nearby anatomical structures to avoid  such as nerves.

What if I  don’t have enough bone for dental implants?

The alternative options for replacing missing teeth include dentures and bridges. However, there are various bone grafting and tissue regeneration procedures that can be carried out to enable treatment with dental implants:

• Sinus augmentation if you need to replace missing teeth at the back of the upper jaw then a sinus augmentation, whereby new bone in the sinus is created can increase the  height of the bone available for the placement of implants in this area
• Onlay Grafting this is where a piece of bone from somewhere else is taken and it is secured  over an area that is deficient in bone, over time the newly placed bone will  fuse with the underlying bone creating a better environment for an implant to  be placed.

Where can  bone be taken from for the graft?

The best  source of bone for your graft is your own bone tissue from else where in your  body and areas that can be used for bone grafts include the chin, back of the  lower jaw, the hip and tibia. Bone taken from your own body offers the most viable and faster healing time when compared to alternatives. In many cases a  combination of artificial bone substitutes and your natural bone is used. In any bone grafting procedure the grafted bone provides an anchor and stimulus for the existing bone to grow onto, eventually providing an environment suitable for the placement of implants.

How long do dental implants last?

Dental implants have been used for over 30 years to replace missing teeth and they can  last a lifetime depending upon how you look after them. Like any other restoration your implant-supported teeth can still be damaged by trauma and affected by gum disease and poor oral hygiene.

How much do dental implants cost?

The price of  dental implants tends to vary considerably and depends on several factors including the level of skill of the surgeon, the type / quality / brand of  implant used, the clinic where the treatment is carried out, the level of  aftercare service provided and obviously the amount of work required (i.e bone  grafting) and number of implants required. In the UK the costs of a single tooth  implant can vary from £800.00 up to £3000.00.

Nobel  Guide is a revolutionary treatment planning and surgical implementation system enabling you to transfer extra oral planning into the mouth with unrivalled  accuracy and ease. The idea of having great beautiful natural looking working teeth by only attending  a few appointments has now become a reality. This procedure is minimally  invasive and will get you back in work in no time. With  only a few clinics in the uk  offering this amazing new treatment this new concept is now available in Bishop Stortford (Houston, Texas and all over the US). This procedure can be used with patient requiring a few teeth to those requiring a  full arch reconstruction. The patient initially is sent for a cone beam ct scan of the jaw. This CT scan is a low dose scan and produces files through the jaw. These  files are then reconstructed on our software producing a 3-D image allowing our surgeon to place the implants with amazing accuracy. This information is then  sent to Sweden where a stent is manufactured. The  stent is secured with pins in the mouth and the implants placed using this key hole procedure avoiding the need to cut the tissue to find the bone. The  information of were the implants have been planned can also be sent to the laboratory at the same time as sending the information to Sweden. A  temporary bridge or even the final bridge can then be screwed onto the implants  during the very same visit. This incredible concept means that our patient can  come in our clinic and walk out in a hour with secured teeth! This is known as  teeth-in-an-hour.

Benefits Accurate  Planning : Using  the data from the ct scan we can place implants with amazing accuracy utilising  all available bone. This means that even the most difficult cases can be  treated. Maximum Comfort : This flapless procedure means less swelling and pain  with faster recovery Cost  Effective : By reducing the number of visit and a faster recovery time means that you don’t  have to take more time off then is absolutely necessary. Immediate  Function : Our  patient can have the surgery and be fully restored with the teeth all in the  same visit.
