Summary

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.)

Conditions

  • Alveolar Bone Loss
  • Alveolar Ridge Augmentation
  • Augmentation, Alveolar Ridge

Interventions

PROCEDURE

Splitting of bone and fixation of bone laminae differ between the 3 groups.

In split-box technique, all osteotomies were made using with piezoelectric surgery. Horizontal and vertical osteotomies were performed 1.5 mm away from adjacent teeth. Lower border osteotomy of the vestibular cortical bone was performed. A chisel osteoma was used to separate completely and mobilize the segmented bone. This separated, corticocancellous block was stabilized on the distance to the native alveolar crest with micro screws. The space between the block and the alveolar crest was filled with allograft. In reverse split box technique, differs from the split-box technique as follows: it involves reversing the separated corticocancellous bone block before fixation. In sliding split box technique, differs from the split-box technique as follows: horizontal osteotomy is performed at the level where the bone thickness reaches at least 3 mm. Separated corticocancellous bone block is slid toward the coronal of alveolar crest and fixed in line with the native alveolar bone.
