Objectives:
This study aims to evaluate the correlation between differences in intraoperative jumping gaps and soft tissue changes around immediate implant placement and provisionalization (IIPP) in the maxillary anterior region. Results will provide a basis for clinical evaluation of the change trend and long-term stability of the labial soft tissue contours of patients with different jumping gaps.
Methods:
Thirty-two patients with single tooth loss in the maxillary aesthetic area were enrolled, and they all received immediate implant placement and restoration. All patients were divided into three groups: A, B, and C according to the size of the jumping gap, group A: horizontal defect dimension (HDD) ≤2 mm; group B: 2 mm
Results:
All implants had osseointegration within 6 months after the surgery. The average thickness of soft tissue contour volume changed by 0.62 mm±0.15 mm, and the average PES was 11.09±0.99. The changes in the gingival mucosa levels in the three groups at 6 months after operation were 0.45 mm±0.11 mm, 0.40 mm±0.12 mm, and 0.35 mm± 0.11 mm, respectively. The changes in the average thickness of the soft tissue contour volume in the three groups at 6 months after the operation were 0.77 mm±0.16 mm, 0.63 mm±0.17 mm, and 0.54 mm±0.11 mm. A moderate negative correlation was found between the jumping gap size and the gingival mucosa level, and the average thickness changed. No significant correlation was found between size of jumping gap and PES.
Conclusions:
Although the contour volume of the labial soft tissue continuously decreased within 6 months after IIPP in the maxillary anterior region, the surgical procedure can achieve a satisfactory aesthetic effect, and the level of soft tissue around the implant can be well maintained.
