Custom-made solutions that last for years
People lose teeth all the time, either through trauma (when teeth are knocked out) or due to decay, gum disease or old age. Whatever the reason for losing 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 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.
A dental bridge is used to bridge a gap (missing teeth) between healthy teeth.
Teeth on either side of the gap are reshaped and reduced in size. These then act as anchors, or abutments. The bridge is attached to these anchor teeth – filling the missing tooth space.
How is a dental implant placed?
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 first be treated. Thereafter, your treatment will be planned following several x-rays to assess the bone quality and check for nearby anatomical structures to avoid before any drilling. The procedure is usually carried out under local anaesthesia; Oral sedation is sometimes used 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 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 six weeks to six months. The bone tissue will grow and anchor itself into the microscopic rough surface of the implant.
After the healing period, when the surrounding gum tissue has matured, the final permanent restoration can be fitted to the implant.
What are advantages of dental implant 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) which 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
once dental implants are fully integrated into your jaw, they function just as well as your own natural teeth: 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 greatly improve function, 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 dental 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 your natural teeth do not need to be prepared or altered in any way
if done correctly, a dental implant should be indistinguishable from your surrounding natural teeth. Dentures can come loose and look unnatural 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 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+) needs to be supported in either the upper or lower jaw, a minimum of five to six 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 thorough 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 a sufficient quantity 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 the 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 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 on how well 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 vary considerably and depends on several factors, including type/quality/brand of implant used, the amount of work required (i.e., bone grafting) and the number of implants required. The costs of a single tooth implant can vary from £1000 up to £3,000
