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.

Conditions

  • Reconstruction of Horizontal Ridge Defects

Interventions

PROCEDURE

free-hand ridge splitting

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.

PROCEDURE

AI/guided ridge splitting

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.
