There are quite a few reasons why gum graft surgery is often considered. The number of indications for this surgery is basically three, which depends on the available data and present dental practice. Indications are as follows:
Problems related to root exposure- the exposed root surface will be quite difficult to brush for the patient. In such cases, the dentist will witness plenty of calculus and plaques surrounding the root area. This is how the root decay begins. The root surface can be protected and covered by undergoing gum graft surgery.
High Sensitivity- the root surface, which is exposed, will give rise to problems like high level of sensitivity. These sensations can be minimized by getting the root surface covered.
Look- it is obvious that the patient will not be happy when it comes to tooth looks. Hence, even aesthetic reasons could also lead to cover the root surface.
In certain cases, the dentist will recommend only grafting of soft tissue with respect to restoration types like implants and crowns, for protecting teeth. Some factors deciding the coverage amount are type of defect in soft tissue, root shape etc. These factors will in turn depend on the amount of loss of bone underlying. There are also some unfortunate cases wherein the dentists are unable to offer covering for the entire exposed surface. There will be some additional surgeries done in order to direct the fresh soft tissue toward the dental crown.
Gum graft surgery procedure
The periodontist will begin gum grafting by collecting some palate (mouth roof) connective tissue. These tissues will be sutured to the affected area of gumline. By this procedure, the exposed part of the root will be covered and the growth of more tissues will be stimulated. Once some amount of tissue is removed from palate for transplantation purpose, the affected part will be packed or sutured for healing. Grafting of soft tissue can be done by three ways as given below:
By using only connective tissue- a layer consisting of group of tissues covers the mouth roof or palate. The part on the roof, which your tongue can touch, is called surface tissue, and the connective tissues are those which can be found between inner bone and surface tissue. The dentist will make use of an incision in order to withdraw some amount of tissue lying inside the surface, which will result in a minor wound on palate. Less pain is the major advantage of this procedure as the minor wound will be well covered while healing.
Using connective tissue with surface tissue- here, both surface and connective tissues are removed for gum graft surgery. The thickness of the graft will be significant in this case.
Biomaterial method- this method will be preferred by the dentist in case donor tissue amount is limited. The amount of soft tissue left at the recipient area will also be a deciding factor for employing this method.
The success rate of gum graft surgery is considerably high if right surgeons and techniques are employed.
