The goal of this clinical study is to investigate the effectiveness of the split-box technique in systemically healthy, non-smoking, over 18 years of age, participants with narrow crests (<5mm bone width) and adequate bone height (>12mm). The main questions it aims to answer are: - The primary objective of the present study is to investigate the effectiveness of the split-box technique by evaluating the change in width and height of the alveolar bone. - The secondary objective is to evaluate the superiority of the split-box technique and its modifications in terms of the amount of bone gain. According to the 3D topography of the alveolar ridge of the patients before augmentation, split box or one of its modifications, reverse split box or sliding split box techniques were selected and applied. (split box was applied if the bone thickness was more than 3 mm at the top of the crest and did not increase towards the lower border at the alveolar bone, reverse split box technique was applied if the bone thickness was more than 3 mm at the top of the crest and increased towards the lower border at the alveolar bone, sliding split box was applied if the bone thickness was less than 3 mm at the top of the crest but the bone thickness increases towards the lower border at the alveolar bone.)

Primary | Horizontal changes in the alveolar bone | To determine the horizontal changes in the alveolar bone, thickness was measured at two different levels. The measurements were titled as follows: crestal width (CW) and screw level width (SLW).
To measure CW, measurements were made horizontally at the highest point of the crest in pre- and post-operative tomography. To measure SLW, in the post-operative tomography, the bone thickness at the screw level was measured horizontally and recorded. In addition, the distance between the anatomical landmark (mandibular basis, mandibular foramen, lower border of nasal or sinus cavity) and the screw level was also measured and recorded. The main goal of this measurement was to provide a reference for SLW measurement on preoperative cone-beam computed tomography (CBCT), since there were no screws. After the measurements in the postoperative CBCT were made, SLW was also made in the preoperative imaging. |

Primary | Vertical changes in the alveolar bone | To determine whether there was vertical bone loss during horizontal augmentation, the height of the alveolar ridge (ARH) was measured. To measure ARH, a line was created between the anatomical landmark and the highest point of the crest, and the length of this line was measured in the pre- and post-operative tomography. | 5 months | |
Secondary | Difference in bone thickness gain at the top of the crest (CW) between the 3 groups | In order to determine the difference between the 3 groups in terms of CW, the difference between the pre- and post-operative values of the 3 groups was determined. These values were compared between the 3 groups. | 5 months | |
Secondary | Difference in bone thickness gain at the top of the screw level (SLW) between the 3 groups | In order to determine the difference between the 3 groups in terms of SLW, the difference between the pre- and post-operative values of the 3 groups was determined. These values were compared between the 3 groups. | 5 months | |
Secondary | Difference in bone loss at alveolar ridge height (ARH) between 3 groups | In order to determine the difference between the 3 groups in terms of ARH, the difference between the pre- and post-operative values of the 3 groups was determined. These values were compared between the 3 groups. | 5 months |
