Clinical application of a positioning annular gingival cutter in minimally invasive stage II implant surgery

Abstract

BACKGROUND:

Dental implant restoration is an effective therapy for missing teeth and is widely used in clinical practice to provide more treatment options for patients.

OBJECTIVE:

To explore the application of a positioning annular gingival cutter in minimally invasive stage II implant surgery and to evaluate its clinical effects.

METHOD:

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.

RESULTS:

The duration of stage II implant surgery using a positioning annular gingival cutter was 9.23 $\pm$ 1.63 min, and the duration of postoperative pain and swelling was 0.73 $\pm$ 0.35 and 0.81 $\pm$ 0.35 d, respectively. The keratinized gingiva width was 2.93 $\pm$ 0.41 mm before surgery and 2.91 $\pm$ 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 $\pm$ 0.49 mm, without significant reduction ( $P>$ 0.05). No obvious inflammation is observed. PD was 2.60 $\pm$ 0.52 mm and BOP was 10%.

CONCLUSION:

The use of a positioning annular gingival cutter in stage II implant surgery achieves a positive and stable clinical effect within a short time.
