Abstract
This study was conducted to assess the effect of ridge splitting technique to increase the width of narrow anterior maxillary edentulous ridge using magnetic mallet.
Eight patients with narrow anterior maxillary edentulous alveolar ridge were selected in this study with assurance of absence of any systemic disease that would prevent successful healing of the bone and soft tissue. The patients ages ranged from 25 to 53 years with a mean±SD 44.38±8.96 years, they were 5 males 62.5% and 3 females 37.5%. All the patients had undergone the alveolar ridge splitting technique using magnetic mallet with simultaneous grafted material to fill the expanded gap.
Before the surgery, patients rinsed their oral cavities with chlorhexidine mouthwash for 60 s before receiving the local anaesthesia.
A full-thickness horizontal incision slightly palatal to the mid-crest using a Bard Parker blade no. 15 was made along the alveolar crest. The reflection of the envelope flap was done using a periosteal elevator. The alveolar ridge was splitted using the pilot split blade then the initial expander was utilized, followed by expanders 1, 2, and 3 until the desired width was reached. Grafted material was filled in the expanded gap. Repositioning of the flap margins after superficial horizontal cutting of the periosteum to facilitate extension of the flap margins and suturing using black silk 3-0 with a horizontal mattress at the midline and interrupted sutures at the rest of the flap.
Clinically, the horizontal bone width was measured preoperatively, during operative, one week postoperatively and three months postoperatively. They were assessed using the spring caliper by millimeters. All cases showed an increase in the ridge width after ridge splitting procedure.
Radiographically, CBCT was done pre-operatively, immediately after the procedure and after 3 months postoperatively, to measure the width, height and bone density.
No post-operative complications were recorded after the surgery, including the absence of signs of infection, wound dehiscence, or benign paroxysmal positional vertigo (BPPV).
The results showed an improvement in horizontal bone width and bone density after ridge splitting by magnetic mallet immediate postoperatively and three months postoperatively compared with baseline preoperative CBCT measures.
