The sampling method is based on the target and continues until the desired number is reached, and then randomization is done using a coin in each person to allocate two areas to the test and control groups, Blinding description: The placement of the implant and the times determined by an examiner who was completely blinded to the surgical procedure are performed. 2 Investigating the effect of hyaluronic acid gel on the stability of dental implants. Intervention 1: Intervention group: 16 patients who are candidates for implant treatment, who have two posterior edentulous areas in the upper or lower jaw without the need for bone, without fenestration and synthesis and bone infection, are selected. In the intervention group, after preparing the osteotomy cavity according to the company's drilling sequence, the implants are randomly placed in one of the cavities with 0.4 ml of hyaluronic acid gel. Intervention 2: Control group:16 patients who are candidates for implant treatment, who have two posterior edentulous areas in the upper or lower jaw, without the need for bone, without fenestration and synthesis and bone infection, are selected. In the control group, after preparing the osteotomy cavity according to the drilling sequence of the company, the implants are placed in the cavities without any changes.
