What Are Dental Implants ?
A natural tooth consists of a crown (the part you see above the gum), and the root (the part hidden under the gum). It is the root in the jawbone that actually holds the natural tooth in place. A dental implant is a small titanium fixture that serves as a replacement for the root portion of a missing natural tooth. Titanium is used because it is most compatible with our human body. The dental implant is placed in the bone of the upper or lower jaw and functions as an anchor for the replacement tooth.
Implants provide additional support where teeth are missing without putting forces onto remaining natural teeth. They may be used to support the replacement of a single missing tooth or a complete functional set for individuals who have lost many or all of their teeth.
What are the Advantages of Dental Implants over Dentures or Bridge?
To make a bridge for 1 missing tooth, the 2 adjacent teeth should be drilled down to half the size. This is a destructive process and results in tooth sensitivity and decay on those 2 teeth. In reality 2 healthy teeth are destroyed to replace one missing tooth. The final restoration is a 3 tooth bridge that connects one drilled down tooth to another, with one artificial tooth in the middle. Using dental implant technology, the same missing tooth can be easily replaced with one dental implant, and without any damage to any other teeth in the mouth. The restored implant tooth is individually supported and is not connected to adjacent teeth.
Dentures are also associated with numerous problems. They are bulky, and unstable in the mouth. Because they constantly move during chewing, they are inefficient in masticating solid foods. People using dentures are forced to limit their diet to soft food. They avoid vegetables, fruits, nuts, meat and other essential nutrients that are important for their health and well being. This results in systemic disorders such as digestive and cardiovascular disease.
People wearing dentures should remove them from their mouth after each use to clean them. This reminds them every day that they have artificial teeth. The emotional and psychological impact of this is profound. Use of denture adhesives to hold dentures in the mouth is quite uncomfortable and has an adverse physical and psychological impact.
These are some of the problems associated with dentures, but by far the most serious problem is facial bone loss and premature aging. This bone loss results in collapse of facial structures, and make the person look much older.
How long do implants last?
Published clinical research shows that implant supported restorations have been successful for over 30 years with success rates now reaching over 95%. These cases were carefully followed from the very beginning and are likely to remain successful for the lifetime of these patients.
Dental implants are designed to be permanent but there are many factors that contribute to their longevity. Home care and regular visits to the dentist or specialist are probably the most critical aspects. However, smoking, grinding of the teeth, or too much pressure on the implants can alter their success.
By comparison, research shows that the Dental bridge lasts from 7-10 years and that Removable partial denture and complete dentures last an average of only 5 years.
What if i have very deficient bone in Either of the Jaws? Is still i am a candidiate for Dental Implants ?
Removable Partial Denture
Yes, even in most compromised deficient bone condition it is possible to rehabilitate mouth with dental implants. With recent innovation of Basal implant, it is possible to rehabilitate even the most compromised area of jaws. Basal Implant engages the most stable bone of the jaws and that bone is basal bone.
Basal bone has very low rate of resorption, hence greater survival of implants. Also treatment with Basal Implant saves time period required for additional Bone augmentation Surgery & Sinus lift surgery . Also it saves patient from another surgery of traumatic bone grafting.
So even in most deficient jaw bone situation, patient can enjoy Basal Implant Supported fixed Prosthesis within just 10- 12 days of Follow up.
