Replacing missing Teeth
Missing teeth can result in altered chewing ability and also affect your confidence when you smile. When missing teeth are left untreated, spaces created by missing teeth can lead to teeth rotating or shifting out of alignment, resulting in a bad bite. This results in unbalanced forces which can cause additional pressure and strain to the teeth leading to risk of remaining teeth becoming damaged, chipped or fractured.
Trower dental offers multiple options to replace missing teeth. Therefore, regardless your social, financial or physical circumstance we will have a suitable solution for you to replace your missing tooth.
Dental Implant
Dental implants have been developed since the late 1960’s and have been used extensively for the replacement of missing teeth. Acting as an artificial tooth root, they are fused into the jawbone to replace natural teeth that are missing. A completed dental implant has three main components: (i) A titanium implant: a metal root (ii) An abutment: a post and (iii) A Crown.
The benefits of Dental Implants are:
- Helps to withstand greater biting forces than dentures
- Gives you an option that feels and looks most natural
- Can improve the appearance of ‘hollowed’ cheeks that can occur after a tooth is extracted
- Are firmly secured into the jaw
- Do not require support from adjacent teeth
- Can be cleaned with normal cleaning routine at home, unlike dentures which require removal at night
There are three stages involved in dental implant treatment – (i) Planning (ii) Surgery and (iii) Restoration.
At Trower Dental, we plan and restore dental implants. For the surgery stage, we refer our patients to be taken care by a dental implant specialist surgeon to have treatment including tooth removal, socket preservation and bone grafting and surgical placement of the dental implant.
Planning for Dental Implants
The planning process begins with diagnostic tests to confirm that you are a suitable candidate for the procedure. This also helps us plan the best treatment for you. The process includes a dental examination, photographs, digital teeth impression and 3-D (CBCT) scan of your jaw.
Restoration of the Dental Implants
After you dental implant has been placed the surgeon with review you after a period of approximately 6-8 weeks to make sure that the dental implant has healed and integrated into the jaw bone. Once the surgeon is satisfied with the placement and integration of the implant you are ready to have your dental implant restored with a crown at Trower Dental. The restoration stage is relatively fast and pain-free and often will require no local anaesthetic. At this stage, a digital impression using the Primescan intraoral scanner, along with DSLR photography will be taken to capture detailed and accurate record of your teeth colour, size, shape and positioning. The scans and photographs will be digitally sent to an Australian dental laboratory, where special techniques are used to custom design and construct an implant crown that will perfectly fit and match your tooth. After a couple of weeks you can return to have your finished implant crown inserted.
Dental Bridge
Dental bridges are appliances that “bridge” the gap created by one or more missing teeth. They are made up of one or more crowns for the teeth adjacent to the gap, along with a false tooth or teeth attached. These anchoring teeth are called abutment teeth and the false teeth are called pontics. There are various types of bridge suitable for various different circumstance.
Conventional Bridge Conventional bridges are used when there are natural teeth present on both sides of the gap created by the missing tooth. They involve reshaping the teeth on either side of the gap to make room for bonding crowns on them, with a pontic in between to replace the missing tooth.
Cantilever Bridge
Cantilever bridges are used when there is an adjacent tooth on only one side of the missing tooth or teeth. The pontic is supported on only one side, rather than on both sides, by one crowned abutments. Since this type of bridge is supported on only one side, it may act as a lever leading to complications such as fractured teeth or loosened crowns. Therefore, this type of bridge is only suitable and recommended in limited circumstances.
Maryland Bridge
Maryland bridges (resin-bonded bridges) are considered a conservative alternative to traditional bridges. These bridges consist of a single pontic that is held in place by a metal or porcelain framework (wing). This framework is bonded onto the back of the tooth adjacent to the missing tooth. Minimal alteration of the adjacent tooth is required – your dentist will need to remove only a very small amount of tooth from the back surfaces of these teeth to make room for the wing. Often this treatment is recommended as a short to medium term solution (for example in a growing patient, or as an interim treatment before having a dental implant placed).
etime, making it worth the investment.
To help you choose your ideal bridge option, your dentist will plan your treatment depending on the number and location of missing teeth, presence and health of the adjacent teeth as well as quantity and quality of your jaw bone (in implant cases).
Composite Resin Bridge
Composite resin bridge is a more affordable fixed (do no require removal like a denture) solution to replace missing teeth. This type of bridge is constructed directly in the mouth in a single dental visit. The procedure is often done in comfort without local anaesthetic. Composite bridges uses fibre re-inforced filaments bonded to the teeth on either side of the missing teeth and require little or no tooth modification. Composite resin bridge has limitation with durability and strength
and is at higher risk of chipping, breaking and staining requiring repair and or replacement. Therefore, this option is only limited for very select scenarios and is often only recommended as a short term solution.
Implant-Supported Bridge
Implant-supported bridges are the most stable means of tooth replacement. Often, one dental implant is placed for every missing tooth. However, for multiple missing teeth, an alternative treatment option is a pontic suspended between two
implant-supported crowns. Patients who are considering an implant-supported bridge must have enough healthy bone in their jaws to support the implants. X-rays, CT scans and other tests may be required to investigate the quality and quantity of the bone. The procedure is expensive, invasive and time consuming, with a long recovery time and post-treatment sensitivity. However, the outcome of this treatment option can last a lifetime, making it worth the investment.
To help you choose your ideal bridge option, your dentist will plan your treatment depending on the number and location of missing teeth, presence and health of the adjacent teeth as well as quantity and quality of your jaw bone (in implant cases).
Dentures
A denture is a removable prosthetic device used to replace missing teeth and associated gum loss. Dentures are also known by other names – such as false teeth or plates. Dentures can be either partial (replacing one or more teeth) or full (replacing all teeth in one jaw or both jaws).
Partial denture
These can be made from one of three different materials: acrylic, metal or flexible resin.
Acrylic resin partial denture
Acrylic is a rigid resin material. In dental prosthetics it is pink for the base and gums and tooth-coloured for the replacement teeth. The partial denture is often held in the mouth through the use of metal clasps which grip onto surrounding natural teeth. When in place, the metal is partially or fully covered by your lips.
Metal partial denture
This is a denture with a metal base, usually made of an alloy containing cobalt and chrome. The portion of the denture used to replace the gums is made of pink acrylic material, and the part used to replace teeth is tooth-coloured. Metal clasps are usually attached to the metal base. A major advantage of using metal for the base is the ability to make it both thin, less bulky, more comfortable and strong. Another design advantage over acrylic dentures is the provision of greater support, which minimises impact on your existing teeth.
Flexible Valplast Partial Denture
This is also pink in colour, but is made using a thinner and flexible resin which can facilitate insertion into the mouth. It comes with metal free clasps and is less bulky and noticeable than other partial dentures. Flexible dentures can not be adjusted or repaired and do not last as long as acrylic or metal dentures but they may be a useful option for some patients.
Full denture
A full denture is an acrylic denture that replaces all of the teeth in one jaw or both jaws. This means that the denture rests on your gums and does not use clasps. For some patients, full dentures may need to be held in place with adhesive. Full dentures can be made either to look like an ideal dentition or to mimic your natural teeth. A little time is usually required to get used to eating and speaking with them.
Over-denture
An over-denture is a denture that is made to fit over existing teeth or roots, or over dental implants. An advantage of over-dentures over full dentures is that the teeth or implants act as a secure anchor.
Immediate denture
An immediate denture is one that is prepared in advance of tooth extraction, then placed on the same day as the extraction procedure. This ensures that the patient does not spend any time without teeth. However, the immediate denture cannot fit as accurately as a denture made after teeth have been extracted. It can sometimes be made to fit well with adjustments, but in most cases it is used as a temporary denture, with a new one being made several months later.
