简要总结
In both complete and partial tooth loss, the use of dental implants as artificial replacements for missing teeth is a well-established and effective treatment modality, leading to high patient satisfaction and improved quality of life (1).
Horizontal deficiencies of the alveolar ridge can hinder implant-supported rehabilitation due to insufficient bone volume to support implant dimensions, negatively affecting the final prosthetic outcome from both functional and esthetic perspectives (2).
The split-crest technique reduces treatment time, the number of required surgical procedures, and the risk of complications, making it more acceptable to patients. Additionally, it allows for dental implant placement during the same surgical procedure and eliminates the need for a donor site for graft harvesting (3).
In this study, patients with posterior tooth loss in a narrow mandibular ridge underwent dental implant rehabilitation following alveolar ridge splitting and expansion performed using osseodensification, piezosurgery, or a magnetic mallet.
详细描述
The objective of this study is to compare ridge width gain following ridge splitting and expansion with simultaneous implant placement using osseodensification, piezosurgery, or a magnetic mallet in individuals with narrow mandibular alveolar ridges.
Thirty-nine patients will be randomly allocated into three groups. In Group 1, ridge splitting and expansion will be performed using piezosurgery and bone expanders, followed by simultaneous implant placement.
In Group 2, osseodensification burs will be used after ridge splitting, with simultaneous implant placement.
In Group 3, a magnetic mallet will be used after ridge splitting, with simultaneous implant placement.

研究组 & 干预措施
Osseodensification group:
Ridge splitting and expansion were carried out by creating horizontal and vertical cuts with piezosurgery, followed by expansion of the alveolar ridge using osseodensification burs
干预措施: Osseodensification (Procedure)
Magnetic mallet group:
Ridge splitting and expansion were performed using piezosurgery to create horizontal and vertical cuts, followed by chisels with a magnetic mallet to expand the ridge
干预措施: Magnetic mallet (Procedure)
Piezo-surgery group
Ridge splitting and expansion were performed with piezosurgery inserts, followed by bone expanders
干预措施: Piezo-surgery (Procedure)
结局指标
主要结局
The marginal bone loss
时间窗: Assessments will be conducted 4 months after surgery and 6 months after functional loading.
Changes in bone height following ridge splitting and expansion were assessed radiographically. Measurements were performed using cone beam computed tomography (CBCT) and periapical radiography
The bone width gain radiographically
时间窗: At baseline, after surgery, 4 months after surgery, and 6 months after functional loading.
The extent of bony expansion represents the increase in alveolar ridge width in the buccolingual direction, as determined by radiographic assessment using CBCT.
次要结局
- Implant stability quotients (ISQ)(Measurements will be taken at the time of surgery and again 4 months postoperatively.)
- Insertion Torque(During the surgical procedure.)
