Dental implant restoration is an effective therapy for missing teeth and is widely used in clinical practice to provide more treatment options for patients.
To explore the application of a positioning annular gingival cutter in minimally invasive stage II implant surgery and to evaluate its clinical effects.
Stage II implant surgery using a positioning annular gingival cutter was performed on 15 selected patients at 15 implant sites with sufficient keratinized gingival width in the posterior region. The patient underwent crown restoration 2 weeks after surgery and returned for follow-up 3 months later. The surgical effects were recorded for each patient, including the duration of surgery, postoperative pain and swelling, keratinized gingiva width, probing depth (PD) measurements, and the percentage of bleeding on probing (BOP) before surgery, during crown restoration, and 3 months after crown restoration. The data were subjected to a paired sample t-test using Statistical Product and Service Solutions (SPSS) 25.0.
The duration of stage II implant surgery using a positioning annular gingival cutter was 9.23 ± 1.63 min, and the duration of postoperative pain and swelling was 0.73 ± 0.35 and 0.81 ± 0.35 d, respectively. The keratinized gingiva width was 2.93 ± 0.41 mm before surgery and 2.91 ± 0.46 mm after crown restoration, demonstrating no significant reduction (P> 0.05). The keratinized gingiva width remained stable 3 months after crown restoration, with an average of 2.85 ± 0.49 mm, without significant reduction (P> 0.05). No obvious inflammation is observed. PD was 2.60 ± 0.52 mm and BOP was 10%.
The use of a positioning annular gingival cutter in stage II implant surgery achieves a positive and stable clinical effect within a short time.
牙种植体修复是治疗缺失牙的有效方法，在临床实践中被广泛应用，为患者提供更多的治疗选择。
探讨定位环形牙龈切割器在微创二期种植手术中的应用，并评估其临床效果。
选择 15 名后牙区角化龈宽度充足的患者，在 15 个种植位点进行二期种植手术，使用定位环形牙龈切割器。术后 2 周进行牙冠修复，术后 3 个月进行随访。记录每位患者的手术效果，包括手术时间、术后疼痛肿胀、角化龈宽度、探诊深度（PD）测量值，以及术前、牙冠修复时和牙冠修复后 3 个月的探诊出血百分比（BOP）。采用 SPSS 25.0 进行配对样本 t 检验。
使用定位环形牙龈切割器进行二期种植手术的时间为 9.23 ± 1.63 min，术后疼痛肿胀时间分别为 0.73 ± 0.35 和 0.81 ± 0.35 d。角化龈宽度术前为 2.93 ± 0.41 mm，牙冠修复后为 2.91 ± 0.46 mm，无明显减少（P＞0.05）。牙冠修复后 3 个月角化龈宽度稳定，平均为 2.85 ± 0.49 mm，无明显减少（P＞0.05）。无明显炎症。PD 为 2.60 ± 0.52 mm，BOP 为 10%。
在二期种植手术中使用定位环形牙龈切割器可在短时间内达到积极稳定的临床效果。
