Wisdom Teeth, also known as third molars, are the four last permanent teeth to erupt in the mouth. Located at the back corners of your mouth on the top and bottom, these teeth usually appear between the ages of 17 and 25. In most cases, Wisdom Teeth erupt naturally, just as the other molars, and cause no problems. However, if a Wisdom Tooth doesn’t have room to grow, it may result in pain, infection or other Dental problems, and you will need to have it pulled out.
Dental implants are titanium rods that are surgically placed in your jaw bone which will subsequently support your missing tooth. The titanium surface on the implant are biologically compatible with living tissue (bone) and over time becomes “joined” or integrated with bone forming a permanent fixture in your jaw.
The artificial tooth is then attached to the implant fixture either by a screw or by cementing on to a connecting abutment.
Implants are very versatile and can replace a single tooth or they can be joined to each other to provide more substantial support from 2 to more teeth. Indeed, we can replace the bulk of usable teeth almost returning you back to “normal”. Obviously, nothing can totally replace a natural tooth but implants can come close provided all care is taken to manage the situation.
From our experience of over 20 years, the following protocol is currently used to provide the most predictable result. For the single tooth
Stage 1 is to construct a provisional (temporary) restoration to allow the gum tissue to heal around a tooth structure and to allow the bone to be “progressively” loaded with a “plastic” (softer) structure to allow for optimal healing.
Stage 2 is the final replacement of the provisional crown with the definitive crown usually done 2-3 months after wearing the provisional or at the patient’s leisure.
In the posterior region where gum aesthetics is not so critical, we could bypass the provisional stage thus saving you some time and money. You can discuss this with your dentist should you wish to bypass the provisional stage. The laboratory construction of the implant provisional or definitive crown is approximately 12-15 working days.
For hybrid bridges and complex bridges where more steps are required to fabricate the prostheses, 4-6 weeks is necessary to complete the prosthetic phase.
In patients who are totally edentulous (missing all their teeth) there are 3 options that are available to them using implants:
1. Have an implant supported overdenture:
This is when we typically place a minimum of 4 implants (for the upper jaw) and 2 implants (for the lower jaw) that will clip on to a removable denture. This is the cheapest option and will give you good retention for your dentures. By being removable, cleaning is easy and should repair be required, it can be easily done.
2. Have an implant-supported hybrid bridge:
A hybrid bridge is basically having a denture attached by screws to the implants. These work extremely well for the lower jaw where the patients no longer have to remove the denture. Whilst it can be done for the upper jaw, cleaning can be an issue and may present a problem to the patient. As the patient ages and become less dexterous to clean the denture, gum disease can occur around the implants leading to infection and eventual loss of the implant.
3. Have an implant supported all porcelain or porcelain fused to metal bridges:
This is when we have custom made teeth made entirely of porcelain or with a combination of porcelain fused to metal (usually a gold alloy) either screwed to the implants or cemented to them. These are expensive as the technical expertise required to create each tooth individually becomes very costly. Nevertheless, it is very comfortable, aesthetically pleasing and can be cleaned easily like natural teeth. This is ideal for the upper jaw if a “fixed” option is chosen.
There will always be a bit of discomfort after any surgical procedure but in most cases, the discomfort can be managed by over the counter pain medication such as Paracetamol (Panadol). Stronger painkillers can be prescribed but, in many cases, this is not necessary. Usually, patients take pain medication for 24-48 hours and taper off after that time.
There will be minor bruising and depending on the location of surgery, your lips may feel swollen and tight.
This will settle down after a few days. You can minimize the swelling by using a cold compress after the surgery.
Yes, as long as your work does not include strenuous activity that will cause your blood pressure to go up. This may lead to more swelling and post-operative bleeding. Usually, you do not need to take time off work for a minor surgery involving 1-4 implants.
Yes, but have a soft diet for the day of surgery. You can go back to a normal diet the next day. Obviously, avoid chewing on the side of surgery until you feel comfortable to chew in that region again.
You must maintain a very high level of oral hygiene before and after implant surgery. You may commence the routine brushing of your teeth the next day after surgery but just take care not to “disturb” the wound which may still be swollen and slightly uncomfortable. You will be provided with a course of antibiotics which you should have started a day before the surgery which you must complete the entire prescribed course. You will also be given some Chlorhexidine gel and a special “ultra-soft” toothbrush to help you clean around the implant. You must apply the gel 5-6 times a day around the wound with a cotton bud until you finish the gel.
This usually happens when you have a major grafting procedure done. In this case, we will ask you to leave the dentures out for 2 weeks if possible. In many cases, patients take a holiday and….. disappear. Time to read several good books or catch up with chores around the house. We will reline or rebase your denture soon after that. This will only take a day to do. From then onwards you will always be able to wear your dentures.
Once again, this can occur under certain conditions. The healing of bone around an implant is very much like bone healing around a “fracture”. In the case of bone fracture, your doctor would immobilize the parts either with a plaster cast or by using plates or pins. This is done so that the fracture can heal properly, and the immobilization of the broken parts is critical for a successful result.
If a tooth is placed immediately on an implant, there is a risk that with everyday eating and chewing that the implant will be subjected to micromovement leading to the failure of the healing bone to integrate successfully with the implant. When this occurs, you will lose the implant and we will have to start all over again. In such cases, it will be costly and time consuming for the patient to pay for the procedure all over again.
When multiple implants are done, especially in the lower jaw, we may be able to do an immediate implant supported temporary bridge as all the implants will be splinted together. Careful planning is required in this case and coordination with the surgeon and dental technician is essential so that the delivery of the prostheses can be done in a timely manner. Please discuss this option with your dentist if this technique appeals to you.
We will try our very best to make the artificial tooth look as realistic as possible. Photos will be taken, together with a colourimetric evaluation of your adjacent teeth done (using the Shade Vision colourimeter) to obtain the best “matching” colour for your tooth/teeth. In some cases, you will need to see our technician to get the best result in his laboratory. There are no additional fees for this service.
What is difficult to predict is what your gums will do around the implant crown. It is possible that with the surgery that the gums may recede slightly around the adjacent teeth and the implant crown itself. The papilla (gum between your teeth) is likely to recede slightly and this may present as a slight cosmetic issue. Obviously, we will try everything possible to minimize the recession but at the end of the day, this aspect of implant dentistry is unpredictable. Your dentist will be happy to show your photos of completed cases to show you what you can realistically expect. You must accept that ultimately an implant crown is still an artificial tooth, and nothing can match the beauty of a natural tooth. However, we will do everything possible to achieve a good result for you.
In all cases, we will always try to use your own bone (autogenous bone). This is the gold standard. If we need more bone, we will use either Bio Oss which is a “Xeno” graft derived from cows (Bovine bone). Alternatively, if you have a problem with animal products, we can use totally artificial synthetic bone such as Bio Active glass particles. Depending on the volume used, we may place a collagen membrane to act as a “band-aid” to hold the graft material into place.
It is essential that you maintain a high level of personal oral hygiene and attend for your regular dental maintenance appointment every 6 months or at the very least every year.
