Comparative Study Between Artificial Intelligence-Assisted/Computer-Guided Versus Conventional Ridge Splitting Utilizing Electromagnetic Mallet for Reconstruction of Horizontal Ridge Defects: A Randomized Controlled Clinical Study
Kafrelsheikh University
22 participants
Aug 27, 2024
INTERVENTIONAL
Conditions
Summary
The current trial aims to assess the efficacy of utilizing the electromagnetic mallet either by AI-assisted digital workflow or by the conventional freehand approach for reconstruction of horizontal ridge defects utilizing the ridge-split and expansion technique.
Eligibility
Inclusion Criteria6
- The target population with inadequate bone volume for implant placement due to width insufficiency of maxillary anterior alveolar ridges.
- Age ranges from 18 to 40 years of both sexes.
- Absence of any complicating systemic condition that may contraindicate surgical procedures and implant placement.
- Adequate oral hygiene.
- Eligible participants should present good general health and agree to random assignment to any of the two parallel study groups.
- Participants had a minimum 3-month post-extraction healing period and a horizontal defect in the maxillary esthetic zone with at least a bone width of 3 mm.
Exclusion Criteria4
- Vertical ridge defect.
- Undercut on the labial/buccal side.
- Thick cortical bone without cancellous bone inside.
- Uncontrolled systematic disorders as, diabetes mellitus, uncontrolled periodontal disease, history of head and neck radiotherapy, smokers, pregnancy, noncompliant patients, allergy to the used medications, uncooperative individuals or those unable to attend the study follow-up appointments.

Interventions
Midcrestal incision will be followed by reflection of a full-thickness flap. A midcrestal cut without vertical osteotomy will be done using electromagnetic mallet unit, and then the cut will be extended deep to the implant length. The ridge will be expanded progressively using bone wedges. Dental implant fixtures will be placed stably with 1 mm minimal thickness of buccal bone plate. Surgical site will be completely closed, and wound edges will be sutured in a tension-free way.
The patient specific guides will be placed and fixed by monocortical osteosynthesis screws at the pre-planned positions at the labial buccal mucosa. A midcrestal cut will be performed on the crest of the alveolar ridge guided by the guide slits. The cuts will be expanded progressively using bone wedges through the guide slits to gradually lateralize and expand the labial alveolar plate of bone, so the labial cortex will move through the intentionally created micro gap till it touches the fitting aspect of the patient-specific guide. Implant drills will be inserted through the guiding holes in the surgical guide, and the implant osteotomy sites will be prepared. Finally, implants will be inserted in the osteotomy sites using a torque wrench in a self-tapping fashion, engaging palatal and basal bone for primary stability.
