Studies evaluating and comparing clinical and radiographic peri-implant indices around narrow diameter implants (NDIs; <3.3 mm) and regular diameter implants (RDIs) in type-2 diabetes mellitus (T2DM) and non-diabetic individuals are deficient.
To estimate and compare the clinical and radiographic indices around NDIs and RDIs placed in T2DM and non-diabetic patients.
Eighty-six patients requiring implant surgery in the posterior mandible were divided into two groups (42 T2DM and 44 non-diabetic individuals). Patients were further categorized into two subgroups on the basis of diameter of implants: (1) patients with NDIs (3.3 mm ø) and (2) patients with RDIs (4.1 mm ø). Clinical indices evaluating plaque index (PI), bleeding on probing (BOP), probing depth (PD), and crestal bone levels (CBL) were recorded around all dental implants at 18 and 36 months follow up. Serum hemoglobin A1c (HbA1c) test was carried out for both groups to assess the profile of glycosylated hemoglobin at baseline, 18 and 36 months of follow up.
The mean age of patients in T2DM group and non-diabetic group was 45.2 and 41.6 years, respectively. At 18 and 36 months follow up, mean HbA1c levels were 6.5% and 4.5% and 6.7% and 4.5% in T2DM and non-diabetic individuals, respectively. A statistically significant reduction in mean HbA1c levels from the baseline to respective follow-up periods were seen in T2DM patients. There was no statistically significant difference in the overall mean scores of PI, BOP, PD, and CBL around NDIs and RDIs among T2DM and non-diabetic patients at 18 and 36 months of follow up.
NDIs show reliable clinical stability and radiographic bone levels as RDIs placed in T2DM and non-diabetic individuals, provided oral hygiene and glycemic status are strictly maintained.
评估和比较窄径种植体（直径<3.3mm）和常规直径种植体在 2 型糖尿病（T2DM）和非糖尿病个体周围的临床和影像学种植体周围指数的研究较少。
评估和比较 T2DM 和非糖尿病患者中放置的窄径种植体和常规直径种植体周围的临床和影像学指数。
将 86 名需要在下颌后牙区进行种植手术的患者分为两组（T2DM 组 42 例，非糖尿病组 44 例）。根据种植体直径将患者进一步分为两组：（1）窄径种植体（3.3mmø）组，（2）常规直径种植体（4.1mmø）组。在 18 和 36 个月的随访中，记录所有种植体周围的菌斑指数（PI）、探诊出血（BOP）、探诊深度（PD）和牙槽嵴顶骨水平（CBL）等临床指标。对两组患者进行血清糖化血红蛋白（HbA1c）检测，以评估基线、18 和 36 个月随访时的糖化血红蛋白水平。
T2DM 组和非糖尿病组患者的平均年龄分别为 45.2 岁和 41.6 岁。在 18 和 36 个月的随访中，T2DM 患者的平均 HbA1c 水平分别为 6.5%和 4.5%，非糖尿病患者的平均 HbA1c 水平分别为 6.7%和 4.5%。T2DM 患者的平均 HbA1c 水平从基线到各随访期均显著降低。在 18 和 36 个月的随访中，T2DM 患者和非糖尿病患者的窄径种植体和常规直径种植体周围的 PI、BOP、PD 和 CBL 的总体平均评分无统计学差异。
在 T2DM 和非糖尿病个体中，窄径种植体与常规直径种植体具有相似的临床稳定性和影像学骨水平，只要严格保持口腔卫生和血糖控制。
