Summary
Poor glycemic control in diabetes mellitus impairs dental implant stability. Higher HbA1c levels in diabetic patients correlate with reduced implant healing and longer recovery times, affecting osseointegration.
Area of Science:
- Oral Implantology
- Endocrinology
- Biomaterials Science
Background:
- Diabetes mellitus is often a contraindication for dental implant therapy.
- The impact of glycemic control on implant osseointegration in diabetic patients is not fully understood.
Purpose of the Study:
- To investigate the relationship between glycemic control and short-term dental implant stability in patients with type 2 diabetes.
- To test the hypothesis that poor glycemic control negatively affects implant stabilization.
Main Methods:
- Prospective clinical study involving 30 non-diabetic individuals (12 implants) and 20 individuals with type 2 diabetes (30 implants).
- Glycated hemoglobin (HbA1c) levels were measured, ranging from 4.7-12.6%.
- Implant stability was assessed using resonance frequency analysis over a 4-month period post-placement.
Main Results:
- All implants exhibited minimum stability 2-6 weeks post-placement.
- Patients with HbA1c levels of 8.1% or higher showed a greater decrease in stability and longer healing times.
- Altered implant stability was observed in relation to hyperglycemic conditions in diabetic patients.
Conclusions:
- Poor glycemic control in type 2 diabetes mellitus is associated with impaired short-term dental implant stability.
- Hyperglycemic conditions directly impact implant integration, potentially affecting long-term success.
- This research highlights the importance of glycemic management for successful dental implant outcomes in diabetic patients.

01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:15Diabetes: Management and Pharmacotherapy
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

01:22Diabetes Mellitus: Overview and Type I Subtype
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

01:16Insulin: Dosing Regimen and Adverse Effects
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

01:24Type II Diabetes II: Pathophysiology
PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
01:36Carbohydrate Metabolism
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
