Summary

Background This study was conducted to investigate the clinical efficacy of Socket-Shield Technique on the first premolar bone preservation in Orthodontic Extraction Treatment.

Methods patients were underwent Orthodontic Extraction Treatment in the First Affiliated Hospital of Guangzhou Medical University were enrolled. Extracted teeth were paired and randomly allocated into two groups: test group (Socket-Shield Technique) and control group. Cone beam computerized tomography were utilized to access the horizontal resorption and vertical resorption at 1mm, 3mm and 5mm from a reference plane of alveolar crest, as well as tooth movement rate at four time-points: before tooth extraction (T0), three months after tooth extraction (T1), the juncture socket-shield was removed (T2) and three months after socket-shield removal (T3).

Conditions

  • Immediate Dental Implant Loading

Interventions

PROCEDURE

Socket-Shield Technique

A high-speed turbine was used to cut the tooth crown 1.5-2 mm from the buccal gingival margin. The tooth was then divided along the long axis, approximately 2 mm from the buccal side(Figure 1c, 1d). The palatal roots were removed using minimally invasive elevation and extraction forceps. Next, the buccal socket-shield was trimmed to approximately 4-6 mm in height (1 mm from the buccal gingival margin)\[18\], 3-4 mm in width, and 1-1.5 mm in thickness\[19,20\]. The trimming process required with clear visualization of the shield and calibration by periodontal probe. Finally, the socket-shield was removed by minimally invasive forceps when the adjacent tooth moved proximate to the shield during the process of closing orthodontic gap.
