Procedures involving animal subjects have been approved by the Chancellor&#39;s Animal Research Committee of the University of California, Los Angeles (ARC protocol number 2002-125), and the Animal Research: Reporting In Vivo Experiments (ARRIVE)22. For this method, eighteen 3-week-old C57BL/6J male mice were used and underwent dental extractions, implant placement and peri-implantitis induction. All dental procedures were performed under 10&#215; microscopic magnification and carried out by train...

This protocol presents a descriptive report on surgical procedures for peri-implantitis induction utilizing a ligature model in mice. Working with mice has advantages, such as being cost-effective, the availability of an extensive genetic array given the many backgrounds23 among other aspects24,25. Over the years, several studies have successfully utilized mice in the medical and dental fields, including in peri-implantitis<sup class="xref...

Dental implants are increasingly prevalent as a desirable choice for replacing missing teeth1. The prevalence of dental implants in the US adult population is projected to increase up to 23% by 20262. Based on a market analysis report by Grand View Research (2022), the global market size of dental implants was projected to reach approximately US $4.6 billion in 2022. Furthermore, it is anticipated to exhibit a steady annual growth rate of around 10% until the year 20303. Unfortunately, the use of dental implants can lead to complications, such as peri-implantitis. Peri-implantitis has been defined as a biofilm-induced condition characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone4.
A systematic review found that the mean prevalence of peri-implantitis was 19.53% (95% Confidence interval [CI], 12.87 to 26.19%) at the patient level and 12.53% (95% CI 11.67 to 13.39%) at the implant-level5. Peri-implantitis represents a growing public health, due to an increase in implant failure and, consequently, substantial treatment costs6.
Understanding the pathogenesis of peri-implantitis is crucial to developing a systematic approach to prevent its onset and progression and maximize dental implants&#39; longevity in terms of aesthetics and function7,8. In this sense, using murine models in dental research has proven advantageous, given that mice share more than 95% of their genes with humans9,10, the number of available online genetic databases, and the ability to reproduce clinical scenarios11. All the described advantages allow the dissection of genetic mechanisms in different diseases12, accessible accommodation and management, and antibodies widely available as human panels, beyond the genetic modification availability (e.g., knockout and overexpression) for inflammatory tissue assessment and disease mapping13. Although advantageous, there are few publications addressing peri-implantitis in mice. This is due to methodological challenges, among others, including the difficulty in obtaining mini-implants or installing them.
To develop peri-implantitis in mice, many protocols have been described, such as ligature-induced peri-implantitis, bacteria-induced peri-implantitis14, Lipopolysaccharide (LPS)-induced peri-implantitis15, or the combination LPS + ligature-induced peri-implantitis16. Here, we will focus on the ligature model because it is the most widely accepted method to induce periodontitis17,18,19 and, more recently, peri-implantitis20,21. The ligature placed around the implants in a submucosal position stimulates plaque accumulation and, consequently, tissue inflamation. So, the development of this approach is based on the indication of a viable cost-benefit technique for pre-clinical investigations on peri-implant diseases. This study aims to describe an experimental model of ligature-induced peri-implantitis in mice and determine whether there is effectiveness in inducing this disease given the observed bone and tissue changes.
The overall goal of this article is to report the protocol applied to induce peri-implantitis in mice by ligature and to observe its effectiveness through tissue evaluation and bone loss around the implants.

experimental model of ligature-induced peri-implantitis in mice

Dental implants have a high success and survival rate. However, complications such as peri-implantitis (PI) are highly challenging to treat. PI is characterized by inflammation in the tissues around dental implants with progressive loss of supporting bone. To optimize dental implants' longevity in terms of health and functionality, it is crucial to understand the peri-implantitis pathophysiology. In this regard, using mouse models in research has proven clear benefits in recreating clinical circumstances. This study aimed to describe an experimental model of ligature-induced peri-implantitis in mice and determine whether there is effectiveness in inducing this disease, given the observed bone and tissue changes. The experimental peri-implantitis induction comprehends the following steps: teeth extraction, implant placement, and ligature-inducted PI. A sample of eighteen 3-week-old C57BL/6J male mice was divided into two groups, ligature (N=9) and control non-ligature (N=9). The evaluation of clinical, radiographical, and histological factors was performed. The ligature group showed significantly higher bone loss, increased soft tissue edema, and apical epithelial migration than the non-ligature group. It was concluded that this pre-clinical model can successfully induce peri-implantitis in mice.

For this method, eighteen 3-week-old C57BL/6J male mice were used and underwent dental extractions, implant placement and peri-implantitis induction. There were nine animals per group which was statistically significant, considering linear bone loss achieving 80% power, 15% standard deviation (&#963;) and 95% confidence interval (&#945; =0.05). Mice were fed a soft diet ad libitum during the experiment. Nine mice received a ligature (ligature-induced periimplantitis-experimental group), and nine mice did not rec...
