Dental implants are a stable and secure surgical option for replacing one or more missing teeth. A dental implant uses an artificial root, usually made of titanium. The implant is surgically inserted into the jawbone and after 4-6 months of healing (successful osteointegration) an artificial tooth is attached to the implant. The implant acts as an anchor to hold the replacement tooth in place. Your dentist may recommend dental implants for the following reasons:
Replace one or more missing teeth without affecting adjacent teeth
Resolve joint pain or bite problems caused by teeth shifting into missing tooth space
Restore a patient's confident smile
Restore chewing, speech, and proper digestion
Your dentist need to do some special X-ray, to check where to place implant to avoid a bad position (ensuring you you can place the crown on the correct bite), and surgical stent guide to help the correct placement of the implant.
To do proper implant that both looks good and has good function, your dentist must make sure you:
Have enough bone for get long term stability. Bone graft may be needed in some cases if there are any bone defects, bone lose, decreased bone volume, or if the location is to close to sinus.
Have enough keratinized soft tissue (thick pink gum tissue around the teeth). Soft tissue grafting may needed in some cases
Are in good condition for healing. Diabetes, smoking, and active periodontal disease create a high risk for implant failure in the future. Additionally, good oral hygiene and routine dental scaling are key for long term survival of the implants.
There are two types of implants:
Screw retained, where crown is attached to the implant post through special screw. This is for easy access for removal of the prosthesis in the case that it requires repair (broken) or replacement in the future.
Cement retain, the crown is cemented with dental cement over the implant post. In this case, it is harder to remove the prosthesis in the event that it requires repair or replacement. It is done in the area where screw may show (front teeth with implant placed in limited angulation).
With our aging population, more and more patient with missing teeth will need help to restore their function and self-esteem with denture services. Either from partially edentulous (some missing teeth) and full edentulous (all the teeth are missing) at 34 ave dental with Dr. Sam Huang, we work to provide high quality dentures at affordable rates for our patients.
Dr. Sam Huang has the experience and is committed to spending the time needed to make sure the dentures we create have the correct shade/shape, look, function and phonetics (correct Vertical dimension of occlusion). There are different types of dentures available based on your need:
- Complete dentures (upper or lower)
- Partial dentures
- Implant overdenture dentures
Your dentist may recommend dentures for the following reasons:
Loss of all teeth in an arch
Loss of several teeth in an arch
Enhancing smile and appearance
Improving chewing, speech and digestion
Complete dentures, like partial dentures, are a removable dental appliance that replaces missing teeth and the surrounding tissue. Dentures are designed to be comfortable and functional. They are very similar in appearance to natural teeth and can dramatically improve your smile and facial appearance.
Complete dentures replace all natural teeth and cover the entire upper or lower jaw. These dentures rest directly on the gum and provide support for the cheeks and lips.
Compete Upper Denture (CUD) are normally made of an acrylic resin (pink color to mimic gum color) and acrylic teeth with different shades available for a good cosmetic match. The denture base covers the roof of mouth to replace the entire upper arch of missing teeth for retention. Most people has good bone ridge height on the upper plus roof of mouth provide large surface called palatal seal has relatively successful and retentive upper denture. The satisfaction rate of upper denture is relatively high.
Compete lower denture (CLD) are made of the same material, however due to tongue and cheek being in the way, and constant motion of tongue and cheek when talk and eat, the lower denture will NOT be as retentive as the upper denture. In addition, the rate of lower bone ridge reabsorbs a lot faster compare to upper ridge. Many people end up with poor bone ridge after teeth being extracted for years. Complaints of lower dentures being loose and causing sore spots due to instability are not uncommon among patients. Despite the technique or tricks the dentist can do to increase the relative retention of lower denture, due to physiological limitations lower denture will take longer time to get use to. A denture adhesive can be used to increase retention for lower denture. Permanent Resilient softling on a lower denture functions as cushion to reduce the chance of sore spots on the lower denture.
The complete denture chewing forces is lot diminished compare to natural teeth, and will therefore require time and patience to learn the new way to chew/eat and talk. Most people will adapt with time, however some people will always want extra chewing ability and extra secure to keep the denture in without worry about it coming out, this is where an Implant over dentures can come into play.
A partial denture is a removable replacement for missing teeth. It consists of prosthetic teeth attached to a gum-coloured base, which attaches to your natural teeth with clasps. A partial denture not only fills in the space created by missing teeth, it prevents surrounding teeth from shifting.
If you have only some missing teeth, removable partial denture can help to restore some chewing functions. It is still removable, not fixed in the mouth. There are a few different styles of partial denture:
Casting metal base partial denture uses a metal base for stability, with acrylic resin for gum, and acrylic teeth for look and function. It contains metal clasps to hook on teeth for retention. It is more retentive then full dentures, and is a very strong, durable prothesis, that can be repaired if damaged. Limitations to consider are metal sensitivity or cosmetic concerns due to the metal arms.
Valplast Flexible Partial denture is a cast thermo plastic denture that is thin, lightweight, and flexible with invisible clasps that surround the natural teeth. Flexible partials are a premium, quality product that offer the benefits of superior esthetics, comfort, function and bio-compatibility. However, flexible partial dentures are more expensive then the metal denture alternative, and have a more limited capacity for repair when damaged.
Acrylic interim partial denture are made of an acrylic resin base, with metal hooks. They are designed for interim use for tissue healing, and monitoring the condition of gum/teeth. these are the the least expensive option, but a major disadvantage is they are not stable in the long term, and easy to distort or break.
Flipper denture (intermediate) is an acrylic denture that may be used to replace just one tooth, or replace several teeth. It can be used as an immediate replacement for an extracted tooth, as an interim replacement when waiting for tissue healing or waiting for implant procedure, and sometimes as a long term replacement if finances are a problem.
Implant Overdenture Dentures
In cases of poor stability with dentures or if a patient cannot get use traditional dentures, implant dentures are an effective alternative that can provide extra retention and stability.
On the lower arch, 2 or 4 implants are placed into lower arch, once they are healed and integrated into the bone, a denture is made over the top of implants, the denture can click into the implants making the denture harder to be removed and very retentive in the mouth.
There are different options on lower implant denture, such as locator denture, mini-implants, all on 4, and bar over denture, base on the bone available for surgery, .
