Bottom Line: The student's t-test was used, to identify the significance of the study parameters.When mesial and distal bone losses were averaged, the radiographic evaluation with the SOPRO imaging software showed an average of 0.80 mm, with a standard deviation of ± 0.18 mm bone loss at the first month, followed by 1.03 mm with a standard deviation of ± 0.19 mm at the third month, and 1.23 mm with standard deviation of ± 0.6 mm at the sixth month.When the defect is more than 2 mm, autogenous grafts with membranes are the best choice.

ABSTRACT

Objectives: (1) To measure the crestal bone levels around implants immediately, and one month, three months, and six months after immediate implant placement, to evaluate the amount of bone level changes in six months. (2) To measure the initial stability in immediate implant placement.

Materials and methods: Ten patients were selected and a total of ten implants were placed in the immediate extraction sites. The change in the level of crestal bone was measured on standardized digital periapical radiographs taken at baseline, first month, third month, and sixth months for each patient, using the SOPRO imaging software. The initial stability of implants was measured with resonance frequency analysis (RFA) and an engine-driven torque. The measurements were statistically analyzed. The student's t-test was used, to identify the significance of the study parameters.

Results: When mesial and distal bone losses were averaged, the radiographic evaluation with the SOPRO imaging software showed an average of 0.80 mm, with a standard deviation of ± 0.18 mm bone loss at the first month, followed by 1.03 mm with a standard deviation of ± 0.19 mm at the third month, and 1.23 mm with standard deviation of ± 0.6 mm at the sixth month. The initial stability with the RFA instrument showed a mean of 55 implant stability quotient (ISQ) values and the torque showed a value of 36.50 Nm.

Conclusions: The implant has to be placed 2 mm below the crestal bone level to compensate the crestal bone loss. The initial stability is achieved by apical preparation of the socket wall and use of straight screw implants. When the defect is more than 2 mm, autogenous grafts with membranes are the best choice.

Mentions: The study protocol was approved by the Ethical Committee of the Meenakshi University, Chennai. All the patients were informed about the procedure being conducted and informed consent was obtained. The implant system used for the study was the Pitt-easy implant system. Preoperative diagnostic casts were obtained to know the interarch relationship and preoperative photographs and radiographs were taken. The implant diameter was selected based on the bone available in the mesio-distal distance between the adjacent root tips and the length was selected 2 mm beyond the socket wall to be restored using a preoperative radio visio graph (RVG) [Figure 1].
