Abstract

Objectives

To evaluate the dimensional reduction of the peri-implant hard tissues and esthetic outcome after immediate implant placement (IIP) in the esthetic zone.

Material and Methods

Patients who received IIP with bone grafts in the esthetic zone, with either immediate or delayed restoration, were included in this retrospective cohort study. The implants were categorized into three groups based on the labial bone thickness (LBT) before implantation: Group 1 (≤ 0.5 mm), Group 2 (0.5–1 mm), Group 3 (≥ 1 mm). The horizontal bone loss (HBL) at 0, 3, 5 mm apical to implant shoulder, peri-implant marginal bone loss (MBL), and Pink Esthetic Score (PES) were used to evaluate the hard and soft tissue after IIP.

Results

A total of 87 implants in 74 patients met the inclusion criteria. Compared to group 3, there was significant severe bone loss in the HBL-0 mm in groups 1 (p = 0.017); and the implant located in the central incisor position and female may led to increased bone resorption (p = 0.021, p = 0.061, respectively). For HBL-3 mm and HBL-5 mm, the non-immediate restoration may reduce bone resorption (p = 0.013, p = 0.022, respectively). The MBL during short-term follow-up and PES score showed no significant difference among three groups.

Conclusions

Despite limitations, our study found that LBT < 0.5 mm significantly affected horizontal bone loss. Meanwhile, immediate restoration, implant position of central incisors and female may also be considered as risk factors for HBL. However, the difference in the labial bone did not significantly affect MBL, or peri-implant soft tissue outcomes.

Trial Registration

This study was registered in a clinical trial registry (www.chictr.org.cn, No: ChiCTR2400087990)

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
