Abstract
Diabetes mellitus is a metabolic disorder characterized by
hyperglycemia with impaired glucose metabolism as the main symptom.
Hyperglycemia can result from a deficiency in insulin secretion, insulin
resistance, or a combination of both. In oral environment, diabetes is
responsible for delayed wound healing, increased alveolar bone resorption, a
risk of up to 3.4 higher than non-diabetics to develop periodontal disease, an
increase in inflammatory tissue destruction and predisposition to infection.
For all those reasons, it was considered a contraindication to put
implant in diabetic patient. However dental implant therapy has become
performed among controlled diabetic patient. The rising success of dental
implants, along with the realized benefits of implant therapy, has shifted
current trends to accommodate patients with controlled diabetes as good
candidates for treatment.
In an effort to reduce heat generation during the preparation of an
implant bed, and to performing atraumatic tooth extraction and subsequent
implant site preparation. Piezosurgery(PS) as a new relevant, and predictable
method was introduced. PS has several advantages such as selective
sectioning of the mineralized bone structures, minimizing the damage to the
surrounding soft tissues. Postoperative healing after PS characterized by
minimal swelling, little bleeding and postoperative morbidity is lower
compared to traditional techniques.
20 male New Zealand rabbits were induced for diabetes, then had been
controlled using insulin injection and were divided into 2 groups; The 1st
group of 10 rabbits received implants prepared by conventional drills while the 2nd group received implants prepared by PS. All rabbits were euthanized
a month after the surgery. Samples were evaluated histologically using
stereomicroscope, light microscope and ESEM, then histomorphometrical
analysis was done in order to estimate BIC,MBIC.Also MBD calculated
using CBCT.
