In establishing an evidence-based rationale for the optimal use of implant therapy in patients with type 2 diabetes mellitus (T2DM), it is essential to first understand the impact of glycemic control on early healing and the success of dental implants. The objective of this study was to evaluate crestal bone loss (CBL) and stability around submerged and non-submerged dental implants in Saudi patients with well- and poorly controlled T2DM.
Thirty-five patients with well-controlled T2DM (24 males and 11 females) and 32 poorly controlled T2DM patients (19 males and 13 females) were included. CBL was measured on digital radiographs; resonance frequency analysis (RFA) measurements were made for each implant at the time of fixture placement and at 3 months in both the groups. A p value less than 0.05 was considered statistically significant.
A total of 124 dental implants were placed. Mean RFA values between baseline and 3 months in poorly controlled T2DM patients was statistically significant (p = 0.048). CBL at first year (p = 0.047), second year (p = 0.041), third year (p = 0.046), and seventh year (p = 0.035) was significantly worse in poorly controlled T2DM. CBL around non-submerged dental implants showed statistically significant differences at all time-intervals (p < 0.05).
Poorly controlled T2DM patients present worse peri-implant bone outcomes as compared to patients with well-controlled T2DM. We suggest that the predictability of successful dental implant therapy outcomes depends on the maintenance of optimal haemoglobin A1c levels.
在为 2 型糖尿病（T2DM）患者建立基于证据的最佳使用种植体治疗的理论基础时，首先了解血糖控制对早期愈合和牙种植体成功的影响至关重要。本研究的目的是评估沙特 T2DM 控制良好和控制不佳的患者中，埋入式和非埋入式牙种植体周围的牙槽骨吸收（CBL）和稳定性。
纳入 35 例 T2DM 控制良好的患者（24 名男性和 11 名女性）和 32 例 T2DM 控制不佳的患者（19 名男性和 13 名女性）。在数字射线照片上测量 CBL；在两组中，在固定器放置时和 3 个月时对每个种植体进行共振频率分析（RFA）测量。p 值小于 0.05 被认为具有统计学意义。
共植入 124 颗牙种植体。控制不佳的 T2DM 患者的 RFA 值从基线到 3 个月的平均值具有统计学意义（p = 0.048）。控制不佳的 T2DM 患者在第一年（p = 0.047）、第二年（p = 0.041）、第三年（p = 0.046）和第七年（p = 0.035）的 CBL 明显更差。非埋入式牙种植体周围的 CBL 在所有时间间隔均具有统计学差异（p < 0.05）。
与 T2DM 控制良好的患者相比，控制不佳的 T2DM 患者的种植体周围骨结局更差。我们认为，成功的牙种植体治疗结果的可预测性取决于维持最佳血红蛋白 A1c 水平。
